Failed to Compile with "-DTARGET_32BIT=ON"

Failed to Compile with "-DTARGET_32BIT=ON"

UESuperGate opened this issue 2 years ago · comments

According to the instructions from docs/32-bit.txt, I built up the environment as follow:

Z3 version 4.8.3, compiled by cmake with CXX_FLAGS="-m32" C_FLAGS="-m32".
LLVM version 12.0.0, compiled by cmake with CXX_FLAGS="-m32" C_FLAGS="-m32".
Ubuntu 20.04.

I set up the compilation configuration of SymCC as follow:

cmake -DQSYM_BACKEND=ON -DTARGET_32BIT=ON -DLLVM_32BIT_DIR="/home1/qingyu/benchmark/llvm-project/build" -DZ3_32BIT_DIR="/home1/qingyu/benchmark/z3/install/lib/cmake/z3"  ..

And I got the failure messages:

And if I try to modify the cmake arguments like this:

cmake -DQSYM_BACKEND=ON -DTARGET_32BIT=ON -DLLVM_32BIT_DIR="/home1/qingyu/benchmark/llvm-project/build" -DZ3_32BIT_DIR="/home1/qingyu/benchmark/z3/install/lib/cmake/z3" -DZ3_TRUST_SYSTEM_VERSION=on  ..

It will still fail with the messages:

Sorry for the extremely late reply. The linker error suggests that your Z3 library is a 64-bit one.

Z3 version 4.8.3, compiled by cmake with CXX_FLAGS="-m32" C_FLAGS="-m32".

It should be CFLAGS and CXXFLAGS, no underscore. Can you check with file /path/to/your/binary/z3 whether Z3 is a 32-bit or 64-bit library?
