Installing on Mac: fatal error 'process.h' file not found

[tylee-fdcl]

While I was installing on Mac, I got the following error messages.

/Users/tylee/Desktop/Homology/python/CMGDB/CMGDB/sdsl-lite/build/lib/../include/sdsl/util.hpp:58:10: fatal error: 'process.h' file not found
   58 | #include <process.h>
      |          ^~~~~~~~~~~
1 error generated.

It seems that <process.h> is specific to Windows. Any suggestion is welcome.

The build system tries to identify the compiler as GCC, Clang, or Intel. Failing that, it assumes that the compiler is MSVC and the target environment is Windows. Unfortunately, after the CMakeLists.txt was last modified, Apple Clang started advertising itself as AppleClang rather than Clang, and the build system cannot identify it correctly.

You should be able to fix the issue by going to CMakeLists.txt, finding the line

if(CMAKE_CXX_COMPILER MATCHES ".*clang.*" OR CMAKE_CXX_COMPILER_ID STREQUAL "Clang")

and replacing it with

if(CMAKE_CXX_COMPILER MATCHES ".*clang.*" OR CMAKE_CXX_COMPILER_ID STREQUAL "Clang" OR CMAKE_CXX_COMPILER_ID STREQUAL "AppleClang")

This repository is no longer maintained. There have been some efforts to develop SDSL 3.0, but it's not 100% compatible with 2.0. We (vgteam) maintain a fork of SDSL 2.0 for our internal purposes, and some other people have been using it as well.
