I'm trying to use Intel Fortran compiler to compile an application, which produce an error during configure when running the following command:
fpp -P conftest.c
And the conftest.c is the following:
# include <assert.h>
The error message is
assert.h(106): #error: #if: syntax error.
I tried both intel 2018 and 2020 compiler, and the same thing happened. Does anybody happen to know what may cause this and how to solve it? Many thanks!
I found the problem is caused by the following line:
#if defined __STDC_VERSION__ && __STDC_VERSION__ >= 201112L
fpp doesn't like the long integer 201112 expressed with a suffix “L”. If I deleted that "L", it then passes the test. But this is a system file and I should not change it.
Why are you pre-processing C source code (the file has a .c extension) with a Fortran preprocessor?
If that file actually contains Fortran source code, why is it trying to include a C standard library header?
Hi Steve and Ian,
Thanks for the reply. This is performed by a "configure" script, and I have no idea why it wants to do this. But since this test doesn't pass, the "configure" won't allow me to install this application.
