Hello,
it turns out that my TDM/MinGW gfortran installation is
incapable of linking even the simplest Fortran 90 programs:
I tried to compile this program:
! fmain.f90 --
! Simple Fortran program using a DLL
!
program fmain
integer :: x
x = 0
!call fvarset( x )
write(*,*) x
end program
(which uses no external user-defined routine as to get
minimal dependencies)
and got the following error messages:
c:/mingw_gcc/bin/../lib/gcc/mingw32/4.3.2/libgfortran.a(list_read.o):list_read.c:(.text+0x249d):
undefined reference to `___mingw_snprintf'
c:/mingw_gcc/bin/../lib/gcc/mingw32/4.3.2/libgfortran.a(list_read.o):list_read.c:(.text+0x261d):
undefined reference to `___mingw_snprintf'
c:/mingw_gcc/bin/../lib/gcc/mingw32/4.3.2/libgfortran.a(list_read.o):list_read.c:(.text+0x2bf1):

c:/mingw_gcc/bin/../lib/gcc/mingw32/4.3.2/libgfortran.a(list_read.o):list_read.c:(.text+0x2e17):
undefined reference to `___mingw_snprintf'
c:/mingw_gcc/bin/../lib/gcc/mingw32/4.3.2/libgfortran.a(write.o):write.c:(.text+0xc4b):
undefined reference to `___mingw_snprintf'
c:/mingw_gcc/bin/../lib/gcc/mingw32/4.3.2/libgfortran.a(write.o):write.c:(.text+0x121f):
more undefined references to `___mingw_snprintf' follow
collect2: ld returned 1 exit status
So it seems to be lacking a system library!
I can continue with trying to get the FORTRAN 77 bindings to work,
but this is not very inspiring :(
(I had fleetingly noticed this before with CMake - it did not want to
build F90/95 bindings.)
Maybe I should install the basic GCC compilers - not the TDM ones.
Regards,
Arjen
