Header cassert not found #52

Closed isv75 closed 1 year ago

isv75 commented 1 year ago

Steps to reproduce:

export $ICSC_HOME=/tmp/icsc
git clone https://github.com/intel/systemc-compiler $ICSC_HOME
cd $ICSC_HOME
git checkout 59d79d7
./install.sh

The compilation will run until "Generating SystemC precompiled header...." is output. It then terminates by "fatal error: 'cassert' file not found".

Running make VERBOSE=1from $ICSC_HOME/build_icsc_rel`, it reveals the compilation command to be:

../bin/clang++ -Xclang -emit-pch -x c++-header /mnt/data/projects/intel-systemc/icsc/systemc/src/systemc.h -o /mnt/data projects/intel-systemc/icsc/build_icsc_rel/systemc/systemc.h.pch -D__SC_TOOL -DSC_TOOL_ANALYZE__ -DNDEBUG -std=c++17 -I/mnt/data/projects/intel-systemc/icsc/systemc/src

Adding -v to this compile command:

This is not really an issue with ICSC, but it would be nice if the documentation/README could say something about this:

I am using GCC version 11 and have installed proper headers to that version. However, some other package (probably NVIDIA) have installed GCC 12 without headers. LLVM/Clang will always select the newest gcc version.

As shown in the verbose compile output, clang will try to find version 12 headers. The search path is shown running clang -v:

Selected GCC installation: /usr/lib/gcc/x86_64-linux-gnu/12 ... /usr/lib/gcc/x86_64-linux-gnu/12/../../../../include/c++

The correct search should have been:

/usr/lib/gcc/x86_64-linux-gnu/12/../../../../include/c++/12

To resolve, install the headers, for example libstdc++-12-dev.

Looks like no opens here, so close it.
