I have an embedded application written in C++ (running on a PowerPC in linux environment) which accesses an external database. So my application needs mysql++ libraries which needs to be built using a powerpc compiler. Before building the libraries, I wanted to build mysql++ libraries for linux on my Ubuntu VM to check the procedure. I downloaded the latest package from Official Website. Then I followed the steps mentioned.
Ran ./configure from the root directory, I got the below error.
*checking for MySQL library directory... configure: error: Didn't find mysqlclient library in '/usr/lib64 /usr/lib /usr/lib64/mysql /usr/lib/mysql /usr/local/lib64 /usr/local/lib /usr/local/lib/mysql /usr/local/mysql/lib /usr/local/mysql/lib/mysql /usr/mysql/lib/mysql /opt/mysql/lib /opt/mysql/lib/mysql /sw/lib /sw/lib/mysql'*
I tried locate mysqlclient and did not find any references, hence I followed instructions given in other forums and tried to install the libmysqlclient15-dev using the below command.
sudo apt-get install libmysqlclient15-dev
The output is as shown below
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'libmysqlclient-dev' instead of 'libmysqlclient15-dev'
libmysqlclient-dev is already the newest version.

After this I tried to locate libmysqlclient and I still couldn't find the libraries (.so files). I tried ./configure again and it failed in the same location with the same error message. How can I install libmysqlclient ?
Once this is solved I will rebuild the mysql++ library using my toolchain for powerpc. Has anyone tried this ? To build mysql++ library I need mysqlclient, in the earlier example I would install it by executing the command apt-get, but the libraries would be compiled using a gnu compiler ? How to cross compile mysqlclient for powerpc ? I guess I need to do the below
Build mysqlclient for powerpc.
Use those libraries and build mysql++ libraries for powerpc.
Use mysql++ and mysqlclient libraries in my application and compile for powerpc.
I am new to linux and databases.
I finally solved this problem. I did the below.
Downloaded the Connector/C (libmysql) source files from here
Cross compiled it for powerpc, below is the command given to cmake
cmake -DCMAKE_INSTALL_PREFIX="~/mysqlclient_C/lib" -DCMAKE_C_COMPILER="ppc_4xx-gcc" -DCMAKE_C_FLAGS="-I/opt/ELDK/4.2/ppc_4xx/usr/include/" -DCMAKE_CXX_COMPILER="ppc_4xx-g++" -DCMAKE_CXX_FLAGS="-I/opt/ELDK/4.2/ppc_4xx/usr/include/" -DCMAKE_EXE_LINKER_FLAGS="-lm"
Then a simple make generated the libmysql libraries.
Downloaded mysql++ source files from here
Cross compiled it for powerpc, below is my configure command
./configure --target=powerpc-linux --host=powerpc-linux --prefix="$HOME/mysql++/lib" --enable-thread-check --with-mysql="$HOME/mysqlclient_C/lib" CC=ppc_4xx-gcc CXX=ppc_4xx-g++ LDFLAGS=-lm CFFLAGS="-I/opt/ELDK/4.2/ppc_4xx/usr/include" CXXFLAGS="-I/opt/ELDK/4.2/ppc_4xx/usr/include"
The mysql++ libraries is generated now.
I have not tested the built libraries yet.

Having a heck of a time trying to build CodeLite for an ARM-based Ubuntu Linux target. (Build instructions here: http://codelite.org/Developers/Linux). I get an error from CMAKE that says Could not locate GTK2. Looking in the CmakeLists.txt file I can see that this is a result of find_package(GTK2) failing to find GTK2. I think I have installed gtk according to what the CodeLite build instructions say to do using the command sudo apt-get install libgtk2.0-dev.
In terms of cmake, I don't understand what a "package" is. How would I [manually] locate this package on my filesystem and how do I get cmake to find it?
For my aarch64 ubuntu 17.04, the libraries and headers were under /usr/lib/aarch64-linux-gnu, so invoking cmake with them produced the correct build files:
cmake -DCMAKE_INCLUDE_PATH=/usr/lib/aarch64-linux-gnu/ -DCMAKE_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu/ -DCMAKE_BUILD_TYPE=Release .. -DCOPY_WX_LIBS=1
I am new to Cassandra. I installed c++ driver from Datastax. Can some one please provide me the steps like in which path I have to create the ‘.c’ file and how I can compile it. I can see some example programs in example folder. Can anyone plz tell me how to compile the example programs.
The cpp-driver uses cmake and depends on libuv. So the first steps would be to ensure you have cmake installed as well as libuv. Depending on your linux distribution it may be as simple as using package manager like apt or yum (i.e. sudo apt-get install cmake libuv-dev)
Building is just a matter of running the following steps in the cpp-driver directory:
cmake .
make
sudo make install
This will install libcassandra.so to somewhere in your lib path. You can then link by providing '-lcassandra' in your parameters to clang or gcc (i.e. clang myfile.c -o myfile -lcassandra)
There is very comprehensive documentation on building from source here.
I wasnt't sure whether to put it on StackOverflow or AskUbuntu, but decided to post it here.
I have a problem building my app. I'm using CMake for building and one of the PkgConfig packages it depends on is linux. And when I'm trying to build it, it shows this error:
-- package 'linux' not found
When I'm removing the linux package from the dependencies, it complains about some Vala libraries isn't found. And the only way it is working is removing linux from the dependencies, then running cmake, then putting it to the dependencies again, then running make, then everything works fine (I don't know why).
I suppose I don't have some Ubuntu package installed and I don't have linux*.pc file, but I can't figure out what to do with it.
Can you help me with it?
UPD: Here is part of my CMakeFiles.txt file that raises the error:

I am trying to install the Vision Workbench on my computer, following the instructions from this homepage: http://lunokhod.org/?p=13. I have installed all dependencies but I have libboost1.54-all-dev instead since I am using Mint 17 (Ubuntu 14.4).
After that I have created the config.options file I do ./autogen and ./configure.
However, I get the following in the logfile:
configure:20861: /usr/include/boost is missing these required libraries: BOOST_PROGRAM_OPTIONS BOOST_FILESYSTEM BOOST_THREAD
Checking for a boost in /usr/include/boost-*
Checking for a boost in /usr/local/cuda/include
Checking for a boost in /usr/local/cuda/include/boost-*
configure:20875: checking for package BOOST
HAVE_PKG_BOOST=no
However, in /usr/include/boost/ I have booth program_options, filesystem and thread.
The .so files are under /usr/lib/x86_64-linux-gnu/ for opencv, boost and flann, but somehow it can only find flann.
Does anyone have an idea about where the error might be?
EDIT: In the log-file I saw that the program looked for cxcore when it searched for opencv, but in the new version it is called opencv_core so I did a symbolic link from cxcore to opencv_core and then ./configure finds opencv. However, boost is still a problem and is necessary to build the program.
EDIT2:
I have now downloaded an earlier version of boost (1.42), and almost all boost programs are found except BOOST_THREAD. When I install the boost library I get the following messages:
error: #error "Threading support unavaliable: it has been explicitly disabled with BOOST_DISABLE_THREADS"
/ Erik
try running
./configure --with-boost="path/to/boost"
if you have more than one version of boost installed, you may need to also set environment variables
HAVE_PKG_BOOST=yes
PKG_BOOST_CPPFLAGS=/path/to/boost
PKG_BOOST_LDFLAGS=/path/to/boost
I'm trying to install the software TinyOWS on a Linux computer. The source code is written in C programming language. I don't have much experience with installing C or C++ programs from source code on Linux. I read installation instructions, and it says that I must follow 3 steps after I unzip the source code folder:
./configure
make
make install
When I run ./configure, I get the following error:
checking for xml2-config... /usr/bin/xml2-config
checking for libxml2 version... 2.7.6
configure: error: You need at least libxml 2.8.0
This means that the software being installed requires version 2.8.0 of a library called libxml2 but my computer only has the 2.7.6 version. Unfortunately I found out that I cannot easily install the libxml 2.8.0 on my Linux distribution. The reason why the software TinyOWS that I'm trying to install requires libxml2.8.0 of the library is because libxml2.7.6 has a small bug. But most of the functionality of the software is not affected by the bug.
So, here is my question:
What files do I have to edit or what command line options do I need to use If I want the ./configure command to use the library libxml2.7.6 instead of libxml2.8.0?
Get the source, in the file configure.in replace the line:
AC_MSG_ERROR([You need at least libxml 2.8.0])
By
AC_MSG_NOTICE([You need at least libxml 2.8.0])
Then, do:
autoreconf -f -i -s
./configure
make
The configure step will not stop. But i think if the developpers have restricted this version of libxml2 there must be a good reason.
