I'm trying to build an embedded system with yocto poky. My layers are:
BBLAYERS ?= " \
/home/dev/microzed/meta \
/home/dev/microzed/meta-yocto \
/home/dev/microzed/meta-yocto-bsp \
/home/dev/microzed/meta-xilinx \
/home/dev/microzed/meta-mono \
"
with git clones:
git clone -b master git://git.yoctoproject.org/poky.git ~/microzed
git clone -b master git://git.yoctoproject.org/meta-xilinx ~/microzed/meta-xilinx
git clone -b master git://git.yoctoproject.org/meta-mono ~/microzed/meta-mono
with bitbake core-image-minimal it all compiles and runs - but no mono.
So if I try to bitbake mono: bitbake core-image-mono it fails with the error:
ERROR: Required build target 'core-image-mono' has no buildable
providers. Missing or unbuildable dependency chain was:
['core-image-mono', 'mono-helloworld', 'mono', 'libgdiplus', 'giflib']
not sure how to resolve this. I don't actually need libgdiplus either... :/ in previous versions it was easy to remove, but the current master seems to have the dependency in quite a few places.
Requires meta-oe
git clone -b master git://git.openembedded.org/meta-openembedded ~/microzed/meta-openembedded
plus the layer:
/home/dev/microzed/meta-openembedded/meta-oe \
you can compile console-only build with:
bitbake core-image-mono-console

I'm trying to create a derivation using nix files, and I'm a little stuck. A package I'm trying to install has a sh file in its repo to build it, and this sh file is running CMake with some arguments.
More specifically, this package is vcpkg.
Here's my vcpkg.nix file:
{ gcc11Stdenv, fetchFromGitHub, ninja, cmake, bash }:
gcc11Stdenv.mkDerivation {
name = "vcpkg-2021.05.12";
src = fetchFromGitHub {
owner = "microsoft";
repo = "vcpkg";
rev = "2021.05.12";
sha256 = "0290fp9nvmbqpgr33rnchn5ngsq4fdll2psvh0bqf0324w2qpsjw";
};
buildPhase = ''
./bootstrap-vcpkg.sh -useSystemBinaries
'';
}
When running it with nix-shell -p 'with (import <nixpkgs> {}); callPackage ./vcpkg.nix {}', I get this error:

It seems that adding cmake to buildInputs makes nix try to configure the project using cmake, but this is not what I'm trying to do since vcpkg don't simply have a CMakeLists.txt file in its repo.
Adding inherit cmake ninja; didn't seem to help.
You can prevent cmake from changing the configure phase by setting dontUseCmakeConfigure=true in your derivation.
From the nixpkgs manual:
6.7.29. cmake
Overrides the default configure phase to run the CMake command. By default, we use the Make generator of CMake. In addition, dependencies are added automatically to CMAKE_PREFIX_PATH so that packages are correctly detected by CMake. Some additional flags are passed in to give similar behavior to configure-based packages. You can disable this hook’s behavior by setting configurePhase to a custom value, or by setting dontUseCmakeConfigure. cmakeFlags controls flags passed only to CMake. By default, parallel building is enabled as CMake supports parallel building almost everywhere. When Ninja is also in use, CMake will detect that and use the ninja generator.
I'm trying to build libsodium-sys dependency in an Azure Docker VM which is based on debian.
Have spend a couple of hours trying to fix this build error, but can't figure out what's going on.
I fixed a couple of build errors by installing missing dependencies as the Azure Docker VM seems very vanilla. Executed commands are below the error.

The cause seems related to the issue explained here: https://gitlab.com/gitlab-org/gitlab-runner/-/issues/1379#note_280986944
For reasons unbeknownst to me, these are the commands I needed to execute to fix it:
rm ~/.bashrc
rm ~/.profile
Environment: Ubuntu 18.04 bionic.
after git clone llvm-project from https://github.com/llvm/llvm-project.
I generated build credentials using Cmake commandline like this:
cmake -DLLVM_TARGETS_TO_BUILD=X86 \
-DLLVM_TARGET_ARCH=X86 \
-DCMAKE_BUILD_TYPE="Release" \
-DLLVM_BUILD_EXAMPLES=1 \
-DCLANG_BUILD_EXAMPLES=1 \
-G "Unix Makefiles" \
../llvm/
after makefile was generated, I then use make to build the project make -j8. somehow after build completion, clang and clang++ etc. are nowhere to be found in /build/bin/.
To my knowledge, if I didn't specify LLVM_ENABLE_PROJECTs, it will build LLVM and clang both by default. why are clang executables missing?
You need to explicitly specify LLVM_ENABLE_PROJECT and put the source code folder of clang in the same level of llvm source folder. The folder name must match the value of LLVM_ENABLE_PROJECT
I have just started exploring NiftyNet.I am getting the following error when I try to run the autocontext_mr_ct_model_zoo.

I'm not quite sure what I've messed up here, any advice welcomed.
Looks like the source code you downloaded is out-of-date, are you running the command with the latest version of NiftyNet?
The pip package is slightly out-of-date at the moment,
you could have the latest source code by running
git clone https://github.com/NifTK/NiftyNet.git
# installing dependencies from the list of requirements
cd NiftyNet/
pip install -r requirements-gpu.txt
# run command from the source code folder
python net_regress.py train \
-c ~/niftynet/extensions/autocontext_mr_ct/net_autocontext.ini \

I'm trying to get openmp to run in my program on Mavericks, however when I try to compile using the flag -fopenmp I get the following error:
ld: library not found for -lgomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The command I am running is:
gcc myProgram.cpp -fopenmp -o myProgram
Also, when I run gcc I get Clang warnings which I find to be very strange. And looking into /usr/bin/gcc it does not appear to link to Clang.
Any suggestions on how to fix my Clang errors and get openmp to compile?
The gcc command in the latest Xcode suite is no longer the GCC frontend to LLVM (based on the very old GCC 4.2.1) but rather a symlink to clang. Clang does not (yet) support OpenMP. You have to install separately another version of GCC, e.g. by following this tutorial or by using any of the available software package management systems like MacPorts and Homebrew.
I just recently attacked this problem and have scripted the process of getting everything working based on the official instructions.
The script will download everything into ~/code for easy maintenance and will append the correct environment variables to your ~/.profile file. For advanced users, pick a nice location you want the lib, bin and include installed and move them manually. The script depends on knowing the latest OpenMP runtime from Intel, which can be altered at the top of the script.
The script should work out of the box with vanilla Mavericks, except for one small problem. In the OpenML runtime make script, it does not reliably accept clang when specified and continues with the default GCC. As such, if you don't have GCC installed (which is not normal on out of the box Mavericks), it will fail to build. To fix this, you must comment out two lines (as noted in the script) based on the libomp_20131209_oss.tgz build of OpenMP. Newer builds of OpenML might break this script, so use at your own peril on newer versions.
Simply save this script into a file, run 'chmod +x filename.sh', and run './filename.sh' from terminal. It will take a while to build LLVM and Clang, so be patient.
EDIT: This script will most likely fail on Yosemite and I am having issues using the built clang2 after the update to the dev builds of OSX 10.10.

If you are running homebrew you can fix this problem by calling:
brew install clang-omp
The compiler will be available under clang-omp++ name
Just worked through this problem. Here's the answer plus how to get it worked with Xcode.
Grab the latest version of openMP runtime library from
https://www.openmprtl.org/download
unzip and compile it by
mkdir build && cd build && cmake .. && make && sudo make install
install it by
sudo cp ./libiomp5.dylib /usr/lib/
sudo cp ./omp.h /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/
Grab openmp/clang from Git following the instructions on http://clang-omp.github.io/
compile openmp/clang
cd llvm && mkdir build && cd build && ../configure --enable-optimized && make -j
sudo make install
normally it would install clang/clang++ into /usr/local/bin, we need replace the Apple clang with our version
cd /usr/bin
sudo mv clang clang-apple
sudo mv clang++ clang++-apple
sudo ln -s /usr/local/bin/clang ./clang
sudo ln -s /usr/local/bin/clang++ ./clang++
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
sudo mv clang clang-apple
sudo mv clang++ clang++-apple
sudo ln -s /usr/local/bin/clang ./clang
sudo ln -s /usr/local/bin/clang++ ./clang++
cd /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
sudo mv -f * ../../
Create a project in Xcode, using the Hello World code on clang-openmp website for test. After created, add "-fopenmp" to Custom Compiler Flags -> Other C Flags in project settings; add /usr/lib/libiomp5.dylib to the build phases of project (project settings -> Build Phases -> Drag /usr/lib/libiomp5.dylib into Link Binary with Libraries)
It should work. Yosemite + Xcode 6 is tested.
Note: the custom clang is NOT as stable as Apple's. Switch back if you meet strange instruction error after compiled.
