Hello,
I have an issue using OpenMP with Clang 8 under Windows.I descried the issue in
https://stackoverflow.com/questions/55976484 and I'd like to describe it here
more carefully and specifically.
Let's say I run those 2 commands to compile a simple code:
clang-cl -Xclang -fopenmp -o bla.obj -c bla.cclang-cl -Xclang -fopenmp -o
bla.exe bla.obj
The linker will link against the supplied libomp.lib (Inside LLVM\lib\).Then
the resulting EXE file will have the requirement of libomp.dll which isn't
supplied in LLVM for Windows installation.
The OpenMP Dynamic Library supplied with LLVM 8 / Clang 8 for Windows is
libiomp5md.dll.This is great as this is Intel's OpenMP library.
Yet they DLL the EXE requires doesn't match the DLL supplied (The EXE requires
libomp.dll while the supplied is libiomp5md.dll).Since many applications out
there use Intel OpenMP library it will be great if instead of having libomp.lib
we'll have libiomp5md.lib which requires libiomp5md.dll as supplied.
I'm sure this incompatibility will be resolved but the most important things is
to have Clang compiled applications (And libraries) compiled with OpenMP to be
able to run under a host program which already loads libiomp5md library with no
conflicts.
Thank You.
