Cannot build master

Hi,

Using master at b0a1c0b72c9c61f8b0a223e08f43498abb64f5e8, I cannot build
LLVM. I configured with:

CC=clang CXX=clang++ cmake -DCMAKE_INSTALL_PREFIX=$HOME/opt/llvm11-git \
        -DCMAKE_BUILD_TYPE=Release \
        -DLLVM_BUILD_LLVM_DYLIB=ON \
        -DLLVM_LINK_LLVM_DYLIB=ON \
        -DBUILD_SHARED_LIBS=OFF \
        -DLLVM_ENABLE_EH=ON \
        -DLLVM_ENABLE_RTTI=ON \
        -DLLVM_HOST_TRIPLE=x86_64-pc-linux-gnu \
        -DLLVM_TARGETS_TO_BUILD="AMDGPU;MSP430;WebAssembly;X86" \
        -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="AVR" \
        -DLLVM_ENABLE_PROJECTS="all" \
        -G "Ninja" ../llvm

The final errors were:

I've been struggling to build with gcc-9.3 and clang 9/10 with DYLIB and
without.

Hi,

Using master at b0a1c0b72c9c61f8b0a223e08f43498abb64f5e8, I cannot build
LLVM. I configured with:

CC=clang CXX=clang++ cmake -DCMAKE_INSTALL_PREFIX=$HOME/opt/llvm11-git
-DCMAKE_BUILD_TYPE=Release
-DLLVM_BUILD_LLVM_DYLIB=ON
-DLLVM_LINK_LLVM_DYLIB=ON
-DBUILD_SHARED_LIBS=OFF
-DLLVM_ENABLE_EH=ON
-DLLVM_ENABLE_RTTI=ON
-DLLVM_HOST_TRIPLE=x86_64-pc-linux-gnu
-DLLVM_TARGETS_TO_BUILD=“AMDGPU;MSP430;WebAssembly;X86”
-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=“AVR”
-DLLVM_ENABLE_PROJECTS=“all” \

Just in general, probably don’t enable “all” projects - some are less maintained, or have narrower build requirements, etc.

3

Can you try DBUILD_SHARED_LIBS=ON ? I saw the error when I compiled a custom pass with shared libs off & passed it to opt.

4

I am nuilding that now.

CC=clang CXX=clang++ cmake -DCMAKE_INSTALL_PREFIX=$HOME/opt/llvm11-git \
        -DCMAKE_BUILD_TYPE=Release \
        -DBUILD_SHARED_LIBS=ON \
        -DLLVM_ENABLE_EH=ON \
        -DLLVM_ENABLE_RTTI=ON \
        -DLLVM_HOST_TRIPLE=x86_64-pc-linux-gnu \
        -DLLVM_TARGETS_TO_BUILD="AMDGPU;MSP430;WebAssembly;X86" \
        -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="AVR" \
        -DLLVM_ENABLE_PROJECTS="all" \
        -G "Ninja" ../llvm

5

Ok, which projects should I get rid of? I'm wanting mlir though, that's
the whole point of building this.

Do you really need to build the C library for MLIR?

If so, it looks like it’s just a missing dependency - MPFR library. Or if you do have that library available, it’s missing expected features.

8

Siva - you might want to take a look at this & maybe some library dependency checking should be added to cmake to make this failure clearer?

Ah! Thanks for sharing the error message. I thought I disabled MPFR pieces if MPFR was not available but I see now that I missed one place. Will send a fix soon.

Thanks,

I have mpfr 4.x and it has the symbols llvm is complaining about.

OK. I was wrong in my previous message. The problem is that we don’t normally test building libc with BUILD_SHARED_LIBC=ON. This should fix it: https://github.com/llvm/llvm-project/commit/1e2772c0a3333f10b3fd0e0220022e80f4b0afd2

Let me know if you still see errors.

Thanks,

I've seen the same error in a shared build on Solaris with gcc 9.3.0.
Try using gcc 8.x or 7.x instead: that fixed the problem for me.

Tried the following last night:

cmake -DCMAKE_INSTALL_PREFIX=$HOME/opt/llvm10-git
-DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF
-DLLVM_BUILD_LLVM_DYLIB=ON -DLLVM_LINK_LLVM_DYLIB=ON
-DLLVM_ENABLE_EH=ON -DLLVM_ENABLE_RTTI=ON
-DLLVM_HOST_TRIPLE=x86_64-pc-linux-gnu
-DLLVM_TARGETS_TO_BUILD="AMDGPU;MSP430;WebAssembly;X86"
-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD="AVR"
-DLLVM_ENABLE_PROJECTS="mlir;clang;clang-tools-extra;lld;compiler-rt;openmp;lldb;libcxx;libcxxabi;pstl;parallel-libs;libclc"
        -G "Ninja" ../llvm

Which almost finished:
