[petsc-users] compile PETSc on win using clang

[Guo, Sam]

Hi Barry,
   Here is the output of win32fe cl --use clang --verbose sizeof.c
Using tool: clang
Win32 Development Tool Front End, version 1.11.4 Fri, Sep 10, 2021  6:33:40 PM
Attempting to create file: C:\cygwin64\tmp\wfe1EB0.tmp
clang
clang: error: no input files
del C:\cygwin64\tmp\wfe1EB0.tmp
Attempting to create file: C:\cygwin64\tmp\wfe1ED1.tmp
clang sizeof.c -link
LINK : fatal error LNK1181: cannot open input file 'ink.lib'
clang: error: linker command failed with exit code 1181 (use -v to see invocation)
del C:\cygwin64\tmp\wfe1ED1.tmp

   clang sizeof.c works which produces a.exe.

   This is from clang -help:
OVERVIEW: clang LLVM compiler

  Please do as Satish previously suggested

~/petsc/lib/petsc/bin/win32fe/win32fe cl --use clang --verbose sizeof.c


  Also do

clang sizeof.c

and send the output of both. Where sizeof.c is

#include <stdio.h>
int main(int argc,char **args)
{
   printf("%d\n",(int)sizeof(int));
   return 0;
}

I may have typos in my sample code so please fix those.

Barry

Is the clang you have from visual studio - as described above?

We don't have experience with using this variant of clang.

If its compatible with 'cl' - and supports the same command interface as 'cl' then the following might work [assuming clang.exe is the compiler binary installed - and available in PATH]:

'--with-cc=win32fe cl --use clang'
