Make command fails. #33

Closed abhaypotharaju closed 4 years ago

I am currently working on Ubuntu 18.04 , clang v3.4 and gcc v4.8

I am able to run CMAKE command successfully, however when I run the run the make command I get the following errors:

CMAKE Output: " _cmake .. -DCMAKE_CXX_COMPILER:FILEPATH=/usr/bin/g++-4.8 -- use LLVM_ROOT : /home/potharaju.a/opt/llvm3.4 -- find LLVM-Config : /home/potharaju.a/opt/llvm3.4/bin/llvm-config -- LLVM version : 3.4svn -- LLVM_LINK found : /home/potharaju.a/opt/llvm3.4/bin/llvm-link -- LLVM_OPT found : /home/potharaju.a/opt/llvm3.4/bin/opt -- LLVM_LLC found : /home/potharaju.a/opt/llvm3.4/bin/llc -- LLVMCOMPILER found : /home/potharaju.a/opt/llvm3.4/bin/clang-3.4 -- Configuring done -- Generating done -- Build files have been written to: /home/potharaju.a/LLVM-Tracer/build"

I have added -no_pie to the LLVMC_FLAGS in the LLVM-TRACER/cmake-scripts/buildBitCode.cmake file however the same problem remain.

I am getting the same error while running the final command: _'python llvm_compile.py $TRACERHOME/example/triad triad' while using the docker image

Sorry for the late reply. I suggest using the Docker image. The reason you're seeing this error is most likely because Ubuntu 18.04 was built with gcc-5, which includes instructions not supported by the gcc-4 linker and assembler. Updating your local version of gcc to gcc-5 might work, but it also might not due to issues with ABI tags. The docker image will solve both of these problems.

Alternatively, try the llvm-6.0 branch. It uses LLVM 6.0 instead of 3.4, and you can use gcc-5 with that. We'll be updating the master branch shortly.

I have tried using the docker image provided but got a similar error as mentioned above in my post. Unfortunately, llvm-6.0 didn't solve the issue (I was using gcc4.8). However, I will try updating gcc and then update you if it works with llvm-6.0

There was a slight update to the docker image for LLVM 3.4 that we pushed about three weeks ago, although I don't think it was related to this issue. Yes, let me know if the LLVM 6 docker image works or not.

Closing due to lack of activity.
