"cargo build --release" fails when running in Ubuntu 18.04 (bionic) #475

When I try to run cargo build --release in my Ubuntu 18.04 (bionic) machine, it fails with the following error:

note: /usr/bin/ld: /home/manuel.mourato/gitlab/weld/target/release/deps/libweld-a1558a4817c2a071.rlib(llvmext.o): 
relocation R_X86_64_32 against `.bss' can not be used when making a PIE object; 
recompile with -fPIC
          /usr/bin/ld: final link failed: Nonrepresentable section on output
          collect2: error: ld returned 1 exit status

error: aborting due to previous error

error: Could not compile `hdrgen`.

I tried adding -C relocation-model=pic to the command above, but it did not work.

Here are some specifications:

$ rustc --version
rustc 1.36.0
$llvm-config --version
8.0.0

I am missing something, or is this a bug? Thank you.

You need LLVM 6.0.

try the following:

$ wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add - $ sudo apt-add-repository "deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-6.0 main" $ sudo apt update && sudo apt install clang-6.0 $ sudo ln -s /usr/bin/llvm-config-6.0 /usr/local/bin/llvm-config $ sudo apt-get install -y zlib1g-dev

It was indeed the llvm version. Thank you.
