Hello everyone, I would like to share some of my thoughts and seek some opinions on coding for const char **ompd_dll_locations.
After reviewing the documentation <https://www.openmp.org/spec-html/5.0/openmpsu192.html>, looking over LLVM approach <https://github.com/OpenMPToolsInterface/LLVM-openmp/blob/3b6c06e354ef1e59da22778a9033d87ed0e3b19d/runtime/src/ompd-specific.cpp#L69-L83> as a reference, looking around in GCC code base, and searching around for similar cases and their solutions, I have just a few more questions before finally putting down some unit tests and code. - This post <https://unix.stackexchange.com/questions/19633/which-header-defines-the-macro-that-specifies-the-machine-architecture>seems to use compiler macro to rely on the compiler to suggest architecture, including 32bit and 64bit. I found some macro in gcc/config/i386/i386.h that seems relevant. Is this an acceptable approach? If yes, which header should I use? If not, should I then compare byte size of int and decide from there? - I did some digging around to find conventional library location. One of the issue, however, is that my Linux x86 64bit machine is currently down for repair. I checked in my FreeBSD x86 64bit machine, which suggested /usr/lib for 64bit library and /usr/lib32 for 32bit library, and my raspberry pi Linux 64bit ARM, which suggested /usr/lib/aarch64-linux-gnu for 64bit library. At the moment, I assumed I would keep the scope small and stay with x86 machine's 32bit and 64bit machines, but I wasn't sure what would be the best path to put in that would accommodate all machines. I haven't even looked into Windows, although I assume it's likely C:\Program Files\system and C:\Program Files\system32. Should I simply put all possible path into the array per arch? (LLVM currently simply puts { "ompd.so", NULL }, but I am assuming this was just a placeholder.) - There doesn't seem to be any dedicated function to assign values to the variable. I would like to create a header file to declare some additional functions, such as one that would assign the value. Is this acceptable and, if so, where would be the best place to put such header file? I would appreciate any suggestions. Cheers and stay safe, Tony Sim
