I'm running Debian on Windows 10 (Windows Subsystem for Linux) and installed Rust using the command:
curl https://sh.rustup.rs -sSf | sh
There were no errors in the install, but when I tried to compile with rustc I got the error linker 'cc' not found.
The Linux Rust installer doesn't check for a compiler toolchain, but seems to assume that you've already got a C linker installed! The best solution is to install the tried-and-true gcc toolchain.
sudo apt install build-essential
If you need to target another architecture, install the appropriate toolchain and target the compilation as follows:
rustc --target=my_target_architecture -C linker=target_toolchain_linker my_rustfile.rs
I ran the following 2 commands and it worked.
sudo apt-get update
sudo apt install build-essential
You have to install some dependencies
for Arch Linux sudo pacman -S base-devel
for Ubuntu sudo apt install build-essential
for Centos sudo yum install gcc
for Solus sudo eopkg it -c system.devel
Solution for CentOS:
yum -y install gcc
if u are on wsl2 - ubuntu try to update the pacakges with following cmds:
sudo apt-get update
sudo apt install build-essential
Solution for Solus:
sudo eopkg it -c system.devel
Please do an "Update and Upgrade" before installing setup tools.
You can fix this problem by adding build essential package in linux
sudo apt install -y build-essential
IF ABOVE IS NOT WORKING: cc is included in the "GCC" package. You need to uninstall GCC and then reinstall it if you have accidentally replaced or removed the cc binary.
I ran the following commands in wsl1, it worked
sudo apt-get update
sudo apt install build-essential
I recently set up an AWS EC2 Linux instance, and I'm trying to install boost using the following code:
wget -c
http://sourceforge.net/projects/boost/files/boost/1.66.0/boost_1_66_0.tar.bz2
tar jxf boost_1_66_0.tar.bz2
cd boost_1_66_0
sudo ./bootstrap.sh --prefix=/usr/local/
./b2
sudo ./b2 install
When I run this, I get the following:
error: toolset gcc initialization:
error: no command provided, default command 'g++' not found
error: initialized from project-config.jam:12
Also, when I tried installing g++, which I thought I had already done by issuing this:
sudo yum install gcc-c++
The result:
Package gcc-c++-4.8.5-1.22.amzn1.noarch already installed and latest version
Nothing to do
On AWS Linux the way to go is described here: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/compile-software.html
Or execute command:
sudo yum groupinstall "Development Tools"
This should help.
It seems like you are missing other build tools required for compiling. Installing following should fix your problem,
sudo yum install -y gcc libxml2-devel gcc-c++ make
You can uninstall the tools afterwards.
I am trying to get a Python script to run on the linux server I'm connected to via ssh. The script uses mysqldb. I have all the other components I need, but when I try to install mySQLdb via setuptools like so:,
python setup.py install
I get the following error report related to the mysql_config command.
sh: mysql_config: command not found
Traceback (most recent call last):
File "setup.py", line 15, in <module>
metadata, options = get_config()
File "/usr/lib/python2.5/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r")
File "/usr/lib/python2.5/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
Has anyone else encountered this error and if so how did you resolve it/what can I do to successfully install mysqldb?
mySQLdb is a python interface for mysql, but it is not mysql itself. And apparently mySQLdb needs the command 'mysql_config', so you need to install that first.
Can you confirm that you did or did not install mysql itself, by running "mysql" from the shell? That should give you a response other than "mysql: command not found".
Which linux distribution are you using? Mysql is pre-packaged for most linux distributions. For example, for debian / ubuntu, installing mysql is as easy as
sudo apt-get install mysql-server
mysql-config is in a different package, which can be installed from (again, assuming debian / ubuntu):
sudo apt-get install libmysqlclient-dev
if you are using mariadb, the drop in replacement for mysql, then run
sudo apt-get install libmariadbclient-dev
Reference:
https://github.com/JudgeGirl/Judge-sender/issues/4#issuecomment-186542797
I was installing python-mysql on Ubuntu 12.04 using
pip install mysql-python
First I had the same problem:
Not Found "mysql_config"
This worked for me
$ sudo apt-get install libmysqlclient-dev
Then I had this problem:
...
_mysql.c:29:20: error fatal: Python.h: No existe el archivo o el directorio
compilación terminada.
error: command 'gcc' failed with exit status 1
Then I tried with
apt-get install python-dev
(If you're using python3, install python3-dev instead.)
And then I was happy :)

Cleaning up...
(Specific to Mac OS X)
I have tried a lot of things, but these set of commands finally worked for me.
Install mysql
brew install mysql
brew unlink mysql
brew install mysql-connector-c
Add the mysql bin folder to PATH
export PATH=/usr/local/Cellar/mysql/8.0.11/bin:$PATH
mkdir /usr/local/Cellar/lib/
Create a symlink
sudo ln -s /usr/local/Cellar/mysql/8.0.11/lib/libmysqlclient.21.dylib /usr/local/Cellar/lib/libmysqlclient.21.dylib
brew reinstall openssl (source)
Finally, install mysql-client
LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/ pip install mysqlclient
Update:
In case this doesn't work, #vinyll suggests to run brew link mysql before step 8.
On Red Hat I had to do
sudo yum install mysql-devel gcc gcc-devel python-devel
sudo easy_install mysql-python
Then it worked.
On python 3.5.2 + any future version
sudo apt-get install libmysqlclient-dev python-dev
The below worked for me on Ubuntu 12.04 LTS:
apt-get install libmysqlclient-dev python-dev
All though it worked, i still went ahead to do the below:
export PATH=$PATH:/usr/local/mysql/bin/
I got the same error while trying to install mysql-python.
This is how I fixed it.
sudo PATH=/usr/local/mysql/bin/:$PATH pip install mysql-python
The problem was that the installer could not find the mysql_config in the default path. Now it can ..and it worked..
15 warnings generated.

Hope this helps.
Thanks.
I fixed this problem with the following steps:
sudo apt-get install libmysqlclient-dev
sudo apt-get install python-dev
sudo python setup.py install
The commands (mysql too) mPATH might be missing.
export PATH=$PATH:/usr/local/mysql/bin/
Step1:-Install Python3 & Python3-dev Both
sudo apt-get install python3 python3-dev
Step2:- Install Python & Mysql Connector
sudo apt-get install libmysqlclient-dev
step3:- Install python mysql client
sudo apt-get install mysqlclient
This will Solve your Problem
The package libmysqlclient-dev is deprecated, so use the below command to fix it.
Package libmysqlclient-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
sudo apt-get install default-libmysqlclient-dev
I think the most convenient way to solve this problem in 2020 is using another python package. We don't need install any other binary software.
Try this
pip install mysql-connector-python
and then
import mysql.connector
mydb = mysql.connector.connect(
host="",
user="",
passwd="",
database=""
)
cursor = mydb.cursor( buffered=True)
cursor.execute('show tables;')
cursor.execute('insert into test values (null, "a",10)')
mydb.commit()
mydb.disconnect()
If you're on macOS and already installed mysql#5.7 via brew install:
brew install mysql-connector-c
brew unlink mysql#5.7
brew link --overwrite --dry-run mysql#5.7 first, to see what symlinks are getting overwritten
brew link --overwrite --force mysql#5.7 to actually overwrite mysql-related symlinks with mysql#5.7
pip install mysqlclient
I fixed it by installing libmysqlclient:
sudo apt-get install libmysqlclient16-dev
In centos 7 this works for me :
yum install mariadb-devel
pip install mysqlclient
The MySQL-python package is using the mysql_config command to learn about the mysql configuration on your host. Your host does not have the mysql_config command.
The MySQL development libraries package (MySQL-devel-xxx) from dev.mysql.com provides this command and the libraries needed by the MySQL-python package. The MySQL-devel packages are found in the download - community server area. The MySQL development library package names start with MySQL-devel and vary based MySQL version and linux platform (e.g. MySQL-devel-5.5.24-1.linux2.6.x86_64.rpm.)
Note that you do not need to install mysql server.
For Alpine Linux:
$ apk add mariadb-dev mariadb-client mariadb-libs
MariaDB is a drop-in replacement for MySQL and became the new standard as of Alpine 3.2. See https://bugs.alpinelinux.org/issues/4264
On my Fedora 23 machine I had to run the following:
sudo dnf install mysql-devel
In CentOS 7 , the following things should be done:
#step1:install mysql
https://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/
#step2:
sudo yum install mysql-devel
or
sudo yum install mysql-community-devel
I think, following lines can be executed on terminal
sudo ln -s /usr/local/zend/mysql/bin/mysql_config /usr/sbin/
This mysql_config directory is for zend server on MacOSx. You can do it for linux like following lines
sudo ln -s /usr/local/mysql/bin/mysql_config /usr/sbin/
This is default linux mysql directory.
I had this issues and solved if by adding a symlink to mysql_config.
I had installed mysql with homebrew and saw this in the output.
Error: The `brew link` step did not complete successfully
Depending on how you got mysql it will be in different places. In my case /usr/local/Cellar/mysql
Once you know where it is you should be able to ma a symbolic link to where python is looking for it. /usr/local/mysql
This worked for me.
ln -s /usr/local/Cellar/mysql/<< VERSION >>/bin/mysql_config /usr/local/mysql/bin/mysql_config
I had the same problem. I solved it by following this tutorial to install Python with python3-dev on Ubuntu 16.04:
sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y python3-pip
sudo apt-get install build-essential libssl-dev libffi-dev python3-dev
And now you can set up your virtual environment:
sudo apt-get install -y python3-venv
pyvenv my_env
source my_env/bin/activate
also, i fetch the same problem
I fixed this problem with the following steps:
First I run this command
sudo apt-get install libmysqlclient-dev
then I install
pip install mysqlclient==2.1.0
this is worked for me
You need to install the python-dev package:
sudo apt-get install python-dev
sudo apt-get install python-mysqldb
Python 2.5? Sounds like you are using a very old version of Ubuntu Server (Hardy 8.04?) - please confirm which Linux version the server uses.
python-mysql search on ubuntu package database
Some additional info:
From the README of mysql-python -
Red Hat Linux
.............
MySQL-python is pre-packaged in Red Hat Linux 7.x and newer. This
includes Fedora Core and Red Hat Enterprise Linux. You can also
build your own RPM packages as described above.
Debian GNU/Linux
................
Packaged as python-mysqldb_::
# apt-get install python-mysqldb
Or use Synaptic.
.. _python-mysqldb: http://packages.debian.org/python-mysqldb
Ubuntu
......
Same as with Debian.
Footnote: If you really are using a server distribution older than Ubuntu 10.04 then you are out of official support, and should upgrade sooner rather than later.
This method is only for those who know that Mysql is installed but still mysql_config can't be find. This happens if python install can't find mysql_config in your system path, which mostly happens if you have done the installation via .dmg Mac Package or installed at some custom path. The easiest and documented way by MySqlDB is to change the site.cfg. Find the mysql_config which is probably in /usr/local/mysql/bin/ and change the variable namely mysql_config just like below and run the installation again. Don't forget to un-comment it by removing "#"
Change below line
"#mysql_config = /usr/local/bin/mysql_config"
to
"mysql_config = /usr/local/mysql/bin/mysql_config"
depending upon the path in your system.
By the way I used python install after changing the site.cfg
sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python setup.py install
So far, all solutions (Linux) require sudo or root rights to install .
Here is a solution if you do not have root rights and without sudo. (no sudo apt install ...):
Download the .deb file of the libmysqlclient-dev, e.g. from this mirror
Navigate to the downloaded file and run dpkg -x libmysqlclient-dev_<version tag>.deb . This will extract a folder called usr.
Symlink ./usr/bin/mysql_config to somewhere that is found on your $PATH:
ln -s `pwd` /usr/bin/mysql_config FOLDER_IN_YOUR_PATH
It should now be able to find mysql_config
Tested on Ubuntu 18.04.
For macOS Mojave , additional configuration was required, for compilers to find openssl you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
I encountered the same problem, just added the path where *mysql_config* resided to the environment variable PATH and it worked for me.
sudo apt-get build-dep python-mysqldb will install all the dependencies to build the package from PIP/easy_install
I want to install Go. I prepared system for support language. But sadly, I can't find Bison and libc6-dev following this command.
sudo apt-get install bison ed gawk gcc libc6-dev make
Then I still can't find the suitable Mercurial for Ubuntu 8.10, which is followed this command.
apt-get install python-setuptools python-dev build-essential
Therefore everyone please guide what I should do in order to install Go completely. My OS is Ubuntu version 8.10. Notice you can post the direct link for me to get packets/files.
Mercurial can typically be installed with
sudo apt-get install mercurial
The package is in universe, which you may not have enabled. The full guide, if you need it, is available here:
https://help.ubuntu.com/community/Mercurial
After installing setuptools et al., the go installation instructions say that you should install mercurial with easy-install, i.e. sudo easy_install mercurial. Are you having trouble with easy_install?
In order to install go with Homebrew run the following command on the terminal:
$ brew install golang
To check the version of go run the following command:
$ go version
To see the location run:
$ which go
To uninstall go :
$ sudo apt-get remove golang-go
I can't figure out what is going wrong here -- any ideas??
I'm running on a Ubuntu 8.04 LTS, and have installed libxml2 and libxslt from these instructions:

However, I installed the latest versions:
libxslt-1.1.24
libxml2-2.7.3
The install was uneventful
-------------------- I set LD_LIBRARY_PATH ----------------------------------

In Ubuntu you need to follow these steps:
sudo apt-get install libxml2-dev
sudo apt-get install libxslt-dev
Jared Evans in this post on his blog, described a solution that worked for me on Ubuntu 8.04 LTS. His trick is to NOT use apt-get to install rubygems, but rather to build it from source. This worked great for me. His post is directed at installing rails, so I used these (modified slightly) steps from it to just install nokogiri:
FIRST INSTALL RUBY WITH APT-GET:
sudo apt-get update
sudo apt-get install ruby irb ri rdoc ruby1.8-dev libzlib-ruby
libyaml-ruby libreadline-ruby libncurses-ruby libcurses-ruby libruby
libruby-extras libfcgi-ruby1.8 build-essential libopenssl-ruby
libdbm-ruby libdbi-ruby libdbd-sqlite3-ruby sqlite3 libsqlite3-dev
libsqlite3-ruby libxml-ruby libxml2-dev
IN ADDITION TO JARED'S INSTRUCTIONS I ALSO INSTALLED (I'm not certain that libxslt1.1 is necessary):
sudo apt-get install libxslt1.1
sudo apt-get install libxslt1-dev
DOWNLOAD RUBYGEMS SOURCE:
Download the latest RubyGems (currently 1.3.6) from rubyforge (I used the zip package).
BUILD RUBYGEMS:
cd /TO/DIRECTORY/WHERE/YOU/UNZIPPED/rubygems-1.3.6/
sudo ruby setup.rb
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem
INSTALL NOKOGIRI:
sudo gem update –system
sudo gem install nokogiri
The response will be:
1 gem installed
Installing ri documentation for nokogiri-1.4.1...

I haven't yet noticed any problems caused by the 'No definition' messages...
Try removing the libxslt* and install them again. That fixed the issue for me.
You have to install the development kits of these libraries.
I get the same error when trying to install to a non-standard location (as I don't have access to directories outside my home directory). It seems as if this answer simply installed to the default location in /usr for success. Or did I misunderstand?
More context about what I'm trying to do at http://groups.google.com/group/nokogiri-talk/browse_thread/thread/c1e909be09e90f5a, if that's helpful.
Here's what worked for me on Ubuntu 11.04 (natty):
sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri
