I get this error if I compile and link a source file without an actual
program, like:
subroutine x
write(8,*) 'Boe'
end subroutine x
> gfortran x.f90
C:/Users/markus/gcc/bin/../lib/gcc/x86_64-w64-mingw32/14.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe:
C:/Users/markus/gcc/bin/../lib/gcc/x86_64-w64-mingw32/14.1.0/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o):crt0_c.c:(.text.startup+0x2e):
undefined reference to `WinMain'
collect2.exe: error: ld returned 1 exit status
Does this mimick your case?
Regards,
Arjen
