I am getting the following error when trying to install flang in SUSE Linux Enterprise 15 SP 6.

I followed these instructions as per manual:

git clone https://github.com/llvm/llvm-project.git
rm -rf build
mkdir build
rm -rf install
mkdir install
ROOTDIR=`pwd`
INSTALLDIR=$ROOTDIR/install

cd build

cmake \
  -G Ninja \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=$INSTALLDIR \
  -DCMAKE_CXX_STANDARD=17 \
  -DCMAKE_EXPORT_COMPILE_COMMANDS=ON \
  -DCMAKE_CXX_LINK_FLAGS="-Wl,-rpath,$LD_LIBRARY_PATH" \
  -DFLANG_ENABLE_WERROR=ON \

  -DLLVM_TARGETS_TO_BUILD=host \
  -DLLVM_LIT_ARGS=-v \
  -DLLVM_ENABLE_PROJECTS="clang;mlir;flang;openmp" \
  -DLLVM_ENABLE_RUNTIMES="compiler-rt" \
  ../llvm-project/llvm

ninja

I couldn't able to build completely:

Can you try compiling without -Werror?

I specified flags of cmake. What should i do now?

These are the instances of WERROR in CMakeCache.txt:

//Build Release candidates with -Werror.
BENCHMARK_ENABLE_WERROR:BOOL=OFF

//Build Release candidates with -Werror regardless of compiler
// issues.
BENCHMARK_FORCE_WERROR:BOOL=OFF

//Fail and stop building flang if a warning is triggered.
FLANG_ENABLE_WERROR:BOOL=ON

//Fail and stop if a warning is triggered.
LLVM_ENABLE_WERROR:BOOL=OFF

//Test CXX_SUPPORTS_WERROR_GLOBAL_CONSTRUCTOR

//Test HAS_WERROR_GLOBAL_CTORS
HAS_WERROR_GLOBAL_CTORS:INTERNAL=

//Test OPENMP_HAVE_WERROR_FLAG
OPENMP_HAVE_WERROR_FLAG:INTERNAL=1

Should I change the flags here. Also, if i do does it install flang without any errors.

Try setting changing FLANG_ENABLE_WERROR to OFF. I don't know if that will fix your issue, but it is one thing you could try.

This seems to be triggering an error within your C++ compiler. Which one are you using?

This suggests that GCC 7.5.0 should be able to compile flang. I have never tested with such old compilers. Perhaps someone else has done so. The easiest thing to do for now would be to try building flang with a newer compiler, if that is an option for you.

Which one would be better and How do i install that specific version. Does it mean I need to build again from start?

@tarunprabhu

I, personally, have never built flang with anything older than GCC 11.

How do i install that specific version

That depends on your OS. I can't help you with that.

Does it mean I need to build again from start?

Yes.

@AkhilAkkapelli

Here, they mentioned
The code has been compiled and tested with GCC versions from 7.2.0 to 9.3.0.

So Iam installing using this version(7.5.0)

@tarunprabhu
Copy link
Contributor

Yes, but I don't think we routinely test with GCC versions that are that old. It could be that the documentation is out of date, but I don't know for sure.

What is the full cmake command that you are using to configure? And have you tried a fresh build after turning off -Werror?

By "fresh build", I mean, "have you tried deleting the build directory and starting again including running cmake again"

I will try it now. Can i use gcc 13 for that?

How do I resolve this issue @tarunprabhu

Those are from clang's sanitizers. I have no idea why they would be failing. Are you doing a clean build? What cmake options have you used?

Are you building flang and compiler-rt separately out of tree? Do you need to build them separately?

I have updated my comment.

Is there a reason you are building flang and compiler-rt separately? Have you tried building them together in-tree

I am following the steps from Building Flang In-Tree and encountered the error mentioned above. Since I don't require compiler-rt unless it affects Flang's front-end functionality, is it essential in my case?

No, compiler-rt is not essential for flang.
