So I am atempting to build the ARA-RISCV build and it requires a RISC-V LLVM toolchain and they give you a "make toolchain-llvm" command and it starts off ok but midway through the build around 2500/3500 it stops and the terminal closes without pointing out any error while it builds.
The command that are used are the ones below:
mkdir -p /.../rvv/install/riscv-llvm
cd /.../rvv/toolchain/riscv-llvm && rm -rf build && mkdir -p build && cd build && \
cmake -G Ninja \
-DCMAKE_INSTALL_PREFIX=/home/alex/Documents/Project/rvv/install/riscv-llvm \
-DLLVM_ENABLE_PROJECTS="clang;lld" \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_C_COMPILER=gcc \
-DCMAKE_CXX_COMPILER=g++ \
-DLLVM_DEFAULT_TARGET_TRIPLE=riscv64-unknown-elf \
-DLLVM_TARGETS_TO_BUILD="RISCV" \
../llvm
cd /.../rvv/toolchain/riscv-llvm && \
cmake --build build --target install
After everything the build is incomplete and a lot of files have not been downloaded.I dont know what is causing this can anybody help?
Please and thank you.
EDIT:It worked by adding -j8 to the last instruction aka
cmake --build build --target install -j8

Building WebRTC directly is somewhat painful (& rather time consuming so not ideal in paid for CI environments) so I've opted to use some excellent precompiled static libraries released on GitHub to speed things up. This has worked perfectly for all platforms I'm targetting (Windows, MacOS, iOS, Apple TVOS, linux...) except for Android.
When linking the binary on Android I encounter several duplicate symbol errors related to the std libary:
ld: error: duplicate symbol: std::logic_error::logic_error(char const*)
>>> defined at stdexcept_default.ipp:24 (../../../../../_source/android/webrtc/src/buildtools/third_party/libc++/trunk/src/support/runtime/stdexcept_default.ipp:24)

It appears that libwebrtc.a for Android includes some libc++ object files and I'm not entirely sure how to successfully link with this library here.
This might be coming down to the libwebrtc.a being compiled with Google's own patched libc++ (Based on what I've read online I believe Google contributes patches to upstream libc++ but they don't wait for the patches to go in - rather they use their fully patched version of libc++ for building WebRTC, Chrome, etc).
When compiling for Linux I actually use the exact versions of clang & libc++ that were downloaded & used in building the static library & I suspect I might need to be doing something similar here - I'm just not entirely sure how given the need to use the Android CMake toolchain.
I've put together a minimal example project on GitHub with Dockerfile that can be used to easily reproduce the above issue.
Does anyone have an idea how I can successfully link the library on Android?
For completeness the source files of interest are:

I try to installing GRPC from sources.
I have Oracle Linux 7.9, GCC 10.2.1 from devtoolset-10 and cmake version 3.21.0-rc1 built from sources.
The way i used:
git clone --recurse-submodules -b v1.37.0 https://github.com/grpc/grpc
cd grpc
mkdir -p cmake/build
pushd cmake/build
cmake -DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF \
-DCMAKE_INSTALL_PREFIX=$/usr/local/bin \
../..
make
make install
After this i see that files from /root/grpc/cmake/build$/usr/local/bin/lib/....files been created in /usr/local/....
Ok. But when i change directory to /usr/local - this directory does`t content files from make install.
What i doing wrong?
BTW, when i try to built 1.38 version of GRPS i return building error:
/root/grpc/src/core/lib/gpr/log_linux.cc: In function ‘void gpr_default_log(gpr_log_func_args*)’:
/root/grpc/src/core/lib/gpr/log_linux.cc:97:62: error: no matching function for call to ‘StrFormat(const char [22], const char*, char [64], int32_t&, long int&, const char*&, int&)’
time_buffer, now.tv_nsec, tid, display_file, args->line);
The following worked for me:
$ git clone --recurse-submodules -b v1.37.0 https://github.com/grpc/grpc
$ cmake -G Ninja -S grpc/ -B grpc-build \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF
$ cmake --build grpc-build --target install
The relevant differences here are that my install prefix doesn't have a stray $ in it and that I set the build type (which you must always do).
I'm on Ubuntu 20.04 LTS using CMake 3.20.5 (the latest release) and GCC 10.3.0. Please try the above commands and see if anything changes.
I'm attempting to compile a C++ library called VRPN with musl instead of glibc, and running into linker errors.

It seems that for some reason, musl's glibc hasn't been linked correctly, but I've been unable to figure out why.
I've read that linking to pre-compiled objects is generally the cause of this type of issue, but in this case, I'm pretty confident that everything is being built from source.
I don't have much experience with compiler internals, and I'm having a hard time finding reading material about musl simple enough that I can understand. Any insight or pointers would be much appreciated.
Thanks!
I managed to figure this one out. I think I was using host libraries rather than a proper musl toolchain. I got it to work by building in the messense/rust-musl-cross docker image (created with musl-cross-make), which contains the gcc toolchain compiled for the x86_64-unknown-linux-musl target.
Here's my working docker build script for future reference.

I'm trying to build a docker container using the following Dockerfile:

CMD /bin/bash
Where the projects I'm trying to clone are written in c++11 and the second of the two (Tfit) requires openmpi/mpich. The first program compiles successfully, but with the second, I'm getting the following error in the last step of the compiler:
/usr/bin/ld: cannot find -lstdc++
collect2: error: ld returned 1 exit status
make: *** [Makefile:20: NU_FIT] Error 1
I searched and found these two links:
cpp: usr/bin/ld: cannot find -l<nameOfTheLibrary>
usr/bin/ld: cannot find -l<nameOfTheLibrary>
But neither of these quite address the problem as I'm guessing I'm just missing a dependency/symlink to a library, but I'm unsure how to achieve this in the build. I can compile this successfully locally, but I have to module load mpi/openmpi-x86_64 to do so. My guess is that this is an openmpi issue when setting the LD_LIBRARY_PATH, but am unsure of how to resolve this in the Docker build.
The first few lines of the Makefile are as follows:

CXXFLAGS = -static-libstdc++ -static-libgcc -Wno-unused-variable -Wno-non-virtual-dtor -std=c++11 -fopenmp -Wno-write-strings -Wno-literal-suffix -D_GLIBCXX_USE_CXX11_ABI=0 -g

Try add libstdc++-static in your list of dnf install. (https://github.com/numenta/nupic/issues/1901)
I'm trying to build Clang with libc++ from sources. And I'm trying to drop libc++ in-tree while building it out-of-tree with the other components. The recipe I use is below.
If I simply place libcxx and libcxxabi in-tree, then configure does not pick them up, and they are not built automatically. I placed them in llvm/projects per LLVM's libc++ Standard Library.
Additionally, adding make cxx to the recipe does not work as advertised on the LLVM's libc++ Standard Library page. It results in:
llvm[0]: Constructing LLVMBuild project information.
make: *** No rule to make target `cxx'. Stop.
When I configure LLVM/Clang with --with-libcxx and --with-libcxxabi:
# Issued from a scratch 'build' directory, which is next to the 'llvm' directory.
../llvm/configure --enable-optimized --enable-cxx11 --with-libcxx --with-libcxxabi \
$OTHER_OPTIONS --prefix=/usr/local
then I receive the following:
configure: WARNING: Unknown project (libcxx) won't be configured automatically
configure: WARNING: Unknown project (libcxxabi) won't be configured automatically
libcxx and libcxxabi are literally what LLVM calls them, so I'm not sure what names to use if they are not correct.
I tried to examine configure for what the package names should be, but its not very helpful. See below for the logic.
How do I configure and build Clang with libc++ (when libc++ and libc++ ABI are in-tree)?
Configure logic for --with-XXX is shown below.
this is all I can find (its not very helpful):
-with-* | --with-*)
ac_package=`expr "x$ac_option" : 'x-*with-\([^=]*\)'`
# Reject names that are not valid shell variable names.
expr "x$ac_package" : ".*[^-_$as_cr_alnum]" >/dev/null &&
{ echo "$as_me: error: invalid package name: $ac_package" >&2
{ (exit 1); exit 1; }; }
ac_package=`echo $ac_package| sed 's/-/_/g'`
eval with_$ac_package=\$ac_optarg ;;

And this Stack Overflow question is related: When is libc++ sources needed when building Clang from sources?
And this discussion of CFE-Dev mailing list: Questions about libc++ for linux and its git repository (if any). The thread says unpacking libcxx into llcm/projects ensures the headers are copied where Clang expects them during make install. But it does not address the --with-XXX question, it does not discuss why libc++ was not built, and it does not discuss how to get make install to actually install the libraries.
Recipe to fetch and build Clang. It works fine when not including libcxx and libcxxabi.

This is script which I used to build libcxxabi and libcxx. It use previously built Clang (with GCC (4.8.3 in my case) and GCC STL):

libc++ and libc++abi aren't maintained to work with configure. I think libc++ might work if you invoke it correctly, but there isn't even a configure script for libc++abi.
See our docs for using cmake with these projects:
# In-tree build:
# Check out libcxx and libcxxabi into llvm/projects
cd llvm
mkdir build && cd build
cmake .. # Linux may require -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
make cxx
