Hello,

We are using PETSc as part of a larger project and are switching from compiling with gcc to using AOCC (clang). However, I am getting an error from my include statements stating that the data type __complex128 is an “unknown type name”. The full error log is attached.

I found this solution online (FreeFem - PETSc compilation error - libblas.a/liblapack.a cannot be used - FreeFEM installation - FreeFEM), which says to comment out a line in the petscconf.h header file. Is this a safe fix or is there a more elegant way to go about this?

Best,

Ben
