I wanted to put together a Rust toolchain using the system package manager rather than downloading the rustup installer, and cross-compile for a Raspberry Pi 3
To that end, in Ubuntu 20.04 I have installed rustc and gcc-arm-linux-gnueabihf.
However, the cargo build --bins --release --target armv7-unknown-linux-gnueabihf command fails with
error[E0463]: can't find crate for `core`
|
= note: the `armv7-unknown-linux-gnueabihf` target may not be installed
Is there a way to get this working, other than curl https://sh.rustup.rs -sSf | sh && rustup target add arm-unknown-linux-gnueabihf?
Chances are that you are better off using a docker image to help.
I found this in general:
https://kerkour.com/rust-reproducible-cross-compilation-with-docker/
and, for armv7 I'd say something akin to:
apt update && apt upgrade -y
apt install -y g++-arm-linux-gnueabihf libc6-dev-armhf-cross
rustup target add armv7-unknown-linux-gnueabihf
rustup toolchain install stable-armv7-unknown-linux-gnueabihf
under Ubuntu should do the trick.

Ok, so kind of getting nowhere here. Before I posted a problem with my Mac M1 having linker issues with Rust Diesel and got nothing. So I spun up an Ec2 instance and tried to run this crate here and got the following:
error: linking with `cc` failed: exit status: 1
...
= note: /usr/bin/ld: cannot find -lpq
I've installed the following:
sudo yum update -y
sudo yum install git -y
sudo yum groupinstall "Development Tools" -y
sudo yum install cmake -y
sudo yum install postgresql-libs -y
Seriously, how are people managing to get this crate running?
From the Diesel Getting Started guide:
If you run into an error like:
note: ld: library not found for -lmysqlclient
clang: error: linker command failed with exit code 1 (use -v to see invocation)
This means you are missing the client library needed for a database backend – mysqlclient in this case. You can resolve this issue by either installing the library (using the usual way to do this depending on your operating system) or by excluding the undesired default library with the --no-default-features flag.
By default diesel depends on the following client libraries:
libpq for the PostgreSQL backend
libmysqlclient for the Mysql backend
libsqlite3 for the SQlite backend
If you are not sure on how to install those dependencies please consult the documentation of the corresponding dependency or your distribution package manager.
For example, if you only have PostgreSQL installed, you can use this to install diesel_cli with only PostgreSQL:
cargo install diesel_cli --no-default-features --features postgres
The error "cannot find -lpq" is your linker telling you that it cannot find the PostgreSQL client library.
I'm on Fedora 36. The problem seemed to be that there were 2 versions of Postgres in my PC, and diesel couldn't figure out which library to use. So here's what solved it:
sudo dnf remove postgresql10-libs
sudo dnf install postgresql14-libs
sudo dnf install postgresql14-devel
Edit: this worked for a bit, but then broke again. I fixed it with:
sudo dnf remove postgresql14-devel
sudo dnf install libpq-devel.x86_64
The issue was caused by a missing library.
For Linux
sudo apt install libpq-dev
cargo install diesel_cli --no-default-features --features postgres
For Windows,
Check the version of rust you have installed
rustup --version
then copy the libq.lib from
C:\Program Files\PostgreSQL\14\lib
to
C:\Users\"Your User"\.rustup\toolchains\"Your version of Rust-Nightly or Stable"\lib\rustlib\x86_64-pc-windows-msvc\lib
Worked for me !!
I tried to create my first substrate chain. Create Your First Substrate Chain
But I got some error while compiling substrate.
failed to run custom build command for librocksdb-sys v6.11.4
Does anybody know how to fix this problem?
You need to install additional library:
sudo apt install clang should help.
sudo apt-get update
sudo apt install make clang pkg-config libssl-dev
This should do the trick.
Reference: https://github.com/paritytech/polkadot/issues/65
From #apopiak
Are you on Apple M1? If, so there are currently issues with building rocksdb there. See here an approach: vikiival.medium.com/run-substrate-on-apple-m1-a2699743fae8
Also others have reported needing to:
You need clone the rust-rocksdb repo and checkout the commit listed here: https://github.com/substrate-developer-hub/substrate-node-template/issues/122 then you can create a config.toml file in your .cargo folder in your home directory and add a path to that cloned repo
You had better update cargo to the nightly version and then try it.
If it keep in stuck error try comment commands, you may will need to study link.

I installed Rust on my Ubuntu 16.04 machine through
curl https://sh.rustup.rs -sSf | sh
as can be seen on the Installation Page.
How do I now uninstall Rust?
To uninstall rustc, rustup and cargo from my Ubuntu 16.04 installation, I did:
rustup self uninstall
and it worked.
If you pay attention to the message you get while installing, you will find the command you are looking for:
As for Linux based operating systems, the following command can be used:
rustup self uninstall
this will remove all the Rust Compiler, Tool Chains and Data including rustc and cargo
If you're one window this should wok, but you have to remove C++ build tools manually if you want to remove it as well, though I would never recommend.
You can do this without manually deleting the old rust binaries by uninstalling cargo and then auto-removing its now un-needed dependencies:
sudo apt remove cargo
sudo apt autoremove
I'm running Debian 7.2 on Google Compute Engine (Though I suspect Centos, Red Hat, and Amazon Linux AMI all have the same problem). After downloading the 64-bit Linux version of the Dart SDK from this page, any dart command I run, for example, dart --version, will output the following error:
./editor/dart/dart-sdk/bin/dart: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./editor/dart/dart-sdk/bin/dart)
./editor/dart/dart-sdk/bin/dart: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by ./editor/dart/dart-sdk/bin/dart)
Update: October 2014: Dart can now be installed on Debian with apt-get:
Instructions summarized from the dart website:
# Enable HTTPS for apt.
sudo apt-get update
sudo apt-get install apt-transport-https
# Get the Google Linux package signing key.
sudo sh -c 'curl https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'
# Set up the location of the stable repository.
sudo sh -c 'curl https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'
sudo apt-get update
# Finally, install the dart package!
sudo apt-get install dart
Instructions for building the binary yourself:
This problem appears to be caused by Google compiling against an edge version of GLIBC (>= 2.15) which is not generally supported on Linux outside of Ubuntu 12 (Precise Pangolin).
First of all, do not attempt to download an experimental version of GLIBC or EGLIBC. I was able to get dart to work using that method, but the rest of my machine fell apart. Updating GLIBC is a recipe for madness.
Instead, the best solution is building dart from source. Despite the GLIBC version requirements of the binary, the source itself has no such requirements. There are wiki pages for installing from source on debian, centos/fedora/red hat/amazon, ubuntu, and other linux versions.
Here is an overview of those steps, which I can confirm works on Debian 7.2. The centos/fedora/redhat steps appear to be the same except they use yum instead of apt-get.
Install subversion and the required build tools:
sudo apt-get -y update
sudo apt-get -y install subversion
sudo apt-get -y install make
sudo apt-get -y install g++
sudo apt-get -y install openjdk-6-jdk
Check out google's depot tools and add gclient to your path
svn co http://src.chromium.org/svn/trunk/tools/depot_tools
export PATH=$PATH:`pwd`/depot_tools
Download the dart source at the desired branch.
Replace 1.2 with whatever branch you wish to build. You can see a list of available versions here. In general, the latest numbered branch is best.
gclient config http://dart.googlecode.com/svn/branches/1.2/deps/all.deps
gclient sync
gclient runhooks
Move into the new dart directory
cd dart
Do only A or B below:
Note: For 32bit, use the --arch=ia32 flag instead.
A. Build the entire Dart SDK including pub, dart2js, dart, etc.:
tools/build.py --mode=release --arch=x64 create_sdk
B. Build just the dart executable:
tools/build.py --mode=release --arch=x64 runtime
The dart executable is now at either out/ReleaseX64/dart or out/ReleaseX64/dart-sdk/bin/dart you can do a smoke test by printing the version
dart/out/ReleaseX64/dart --version
The output should be something like Dart VM version: 1.2.0 (Mon Mar 3 03:06:20 2014) on "linux_x64".
How to help fix this issue
This was much more painful than it needed to be, since the binary clearly doesn't need to be built using GLIBC >= 2.15. If you wish to draw attention to this issue, please star this dart bug.
I am trying to install the gnu arm toolchain for ubuntu. I first downloaded the tar from CodeSourcery. However when I go into the bin folder, I cannot run any of the binaries. I have tried with ./ and without and putting it in the PATH and it keeps telling me "Command not Found" yet the file is there in the folder right in front of me. Then I tried sudo apt-get install gcc-arm-linux-gnueabi except after it says it has installed successfully, I cannot find it with whereis gcc-arm-linux-gnueabi. Can anyone help?
fixed, using:
sudo apt-get install gcc-arm*
Are you compiling on a 64-bit OS? Try:
sudo apt-get install ia32-libs
I had the same problem when trying to compile the Raspberry Pi kernel. I was cross-compiling on Ubuntu 12.04 64-bit and the toolchain requires ia32-libs to work on on a 64-bit system.
See http://hertaville.com/2012/09/28/development-environment-raspberry-pi-cross-compiler/
CodeSourcery convention is to use prefix arm-none-linux-gnueabi- for all executables, not gcc-arm-linux-gnueabi that you mention. So, standard name for CodeSourcery gcc would be arm-none-linux-gnueabi-gcc.
After you have installed CodeSourcery G++, you need to add CodeSourcery directory into your PATH.
Typically, I prefer to install CodeSourcery into directory like /opt/arm-2010q1 or something like that. If you don't know where you have installed it, you can find it using locate arm-none-linux-gnueabi-gcc, however you may need to force to update your locate db using sudo updatedb before locate will work properly.
After you have identified where your CodeSourcery is installed, add it your PATH by editing ~/.bashrc like this:
PATH=/opt/arm-2010q1/bin:$PATH
Also, it is customary and very convenient to define
CROSS_COMPILE=arm-none-linux-gnueabi-
in your .bashrc, because with CROSS_COMPILE defined, most tools will automatically use proper compiler for ARM compilation without you doing anything.
if you are on 64 bit os then you need to install this additional libraries.
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
got the same error when trying to cross compile the raspberry pi kernel on ubunto 14.04.03 64bit under VM. the solution was found here:
-Install packages used for cross compiling on the Ubuntu box.
sudo apt-get install gcc-arm-linux-gnueabi make git-core ncurses-dev
-Download the toolchain
cd ~
git clone https://github.com/raspberrypi/tools
-Add the toolchain to your path
PATH=$PATH:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian:~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin
notice the x64 version in the path command
I was also facing the same issue and resolved it after installing the following dependency:
sudo apt-get install lib32z1-dev
If you are on a 64bit build of ubuntu or debian (see e.g. 'cat /proc/version') you should simply use the 64bit cross compilers, if you cloned
git clone https://github.com/raspberrypi/tools
then the 64bit tools are in
tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64
use that directory for the gcc-toolchain.
A useful tutorial for compiling that I followed is available here Building and compiling Raspberry PI Kernel (use the -x64 path from above as ${CCPREFIX})
You have installed a toolchain which was compiled for i686 on a box which is running an x86_64 userland.
Use an i686 VM.
Its a bit counter-intuitive. The toolchain is called gcc-arm-linux-gnueabi. To invoke the tools execute the following: arm-linux-gnueabi-xxx
where xxx is gcc or ar or ld, etc
try the following command:
which gcc-arm-linux-gnueabi
Its very likely the command is installed in /usr/bin.
I had to cross compile C code in Ubuntu for ARM. This worked for me:
$ sudo apt install gcc-arm-none-eabi
Later, tested it on the qemu emulator
#Install qemu
sudo apt-get install qemu qemu-user-static qemu-system-arm
#Cross compile "helloworld.c"
$ arm-none-eabi-gcc --specs=rdimon.specs -Wl,--start-group -lgcc -lc -lm -lrdimon -Wl,--end-group helloworld.c -o helloworld
#Run
qemu-arm-static helloworld
