Playing around some more with NightStrike's builds: there was a build
entitled mingw-w64-bin_x86-64-mingw_20080528.zip that doesn't work
quite right: if you compile a single file everything is OK:
C:\gcc_mingw64\test>gfortran -v
Using built-in specs.
Target: x86_64-pc-mingw32
Configured with:
../gcc/configure -q --prefix=/var/tmp/w64 --with-sysroot=/var/t
mp/w64 --host=x86_64-pc-mingw32 --target=x86_64-pc-mingw32 --silent
Thread model: win32
gcc version
4.4.0 20080528 (experimental) (GCC)
C:\gcc_mingw64\test>type hello.f90
print*, 'Hello, world';end
C:\gcc_mingw64\test>gfortran hello.f90 -ohello
C:\gcc_mingw64\test>hello
Hello, world
Even if you compile two C source files together it works:
C:\gcc_mingw64\test>gcc -v
Using built-in specs.
Target: x86_64-pc-mingw32
Configured with:
../gcc/configure -q --prefix=/var/tmp/w64 --with-sysroot=/var/t
mp/w64 --host=x86_64-pc-mingw32 --target=x86_64-pc-mingw32 --silent
Thread model: win32
gcc version
4.4.0 20080528 (experimental) (GCC)
C:\gcc_mingw64\test>type hello3.c
void hello4();
int main()
{
hello4();
return 0;
}
C:\gcc_mingw64\test>type hello4.c
#include
void hello4()
{
printf("Hello, world\n");
return;
}
C:\gcc_mingw64\test>gcc hello3.c hello4.c -ohello3
C:\gcc_mingw64\test>hello3
Hello, world
But if you compile two Fortran source files together...
C:\gcc_mingw64\test>type hello1.f90
program hello1
call hello2
end program hello1
C:\gcc_mingw64\test>type hello2.f90
subroutine hello2
write(*,*) 'Hello, world'
end subroutine hello2
C:\gcc_mingw64\test>gfortran hello1.f90 hello2.f90 -ohello1
c:/gcc_mingw64/bin/../lib/gcc/x86_64-pc-mingw32/4.4.0/../../../../x86_64-pc-ming

With several hundred lines of errors to follow. Instead, it works
to add a couple of libraries:
C:\gcc_mingw64\test>gfortran hello1.f90
hello2.f90 -lkernel32 -luser32 -ohello1
C:\gcc_mingw64\test>hello1
Hello, world
The problem doesn't occur for the i686-pc-mingw32 hosted version
of mingw-w64-bin_i686-mingw_20080524.zip :
C:\gcc_mingw64a\test\hello>x86_64-pc-mingw32-gfortran -v
Using built-in specs.
Target: x86_64-pc-mingw32
Configured with:
../gcc/configure --prefix=/var/tmp/rt --with-sysroot=/var/tmp/r
t --host=i686-pc-mingw32 --target=x86_64-pc-mingw32 -q --silent
Thread model: win32
gcc version 4.4.0 20080523 (experimental) (GCC)
C:\gcc_mingw64a\test\hello>x86_64-pc-mingw32-gfortran hello1.f90
hello2.f90 -ohe
llo1
C:\gcc_mingw64a\test\hello>hello1
Hello, world
So is this a problem that can be sorted out from the gfortran end
or is it something only the mingw 64 guys can do anything about?
