example files fail when compiled on windows

Hi,

I've recently compiled mkl example files like pardiso_unsym_c.c and others on windows using pgi compilers. Specifically, I use the lines

set "MKL_ROOT=C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2019.1.144\windows\mkl"

set "MKL_LIBS=%MKL_ROOT%\lib\intel64_win"

pgcc -DMKL_ILP64 -I"%MKL_ROOT%\include" -c pardiso_unsym_c.c

pgcc pardiso_unsym_c.obj -L"%MKL_LIBS%" mkl_intel_ilp64.lib mkl_sequential.lib mkl_core.lib

It compiles without error. However, when I attempt to run the resultant .exe file, I get the error message

Error during symbolic factorisation: -1

The pardiso error codes (listed here) say this means there is "input inconsistency". As the error implies, this happens during the symbolic phase (line 121 in pardiso_unsym_c.c).

Thanks for report. At the

Thanks for report. At the first glance everything looks correct. I have no pgcc install on my side. Could you check the problem with Microsoft compiler?

Hi,

No problem. I will try with the Microsoft compiler and see if the issue persists. FWIW When I switched from ILP64 to LP64, the examples compiled and ran successfully with pg compilers.

using the same example, MKL

using the same example, MKL 2019 u1, microsoft compiler, ILP64 mode, I see no problem on my side,

Below are more details about compiling, linking and execution outputs:
