[SOLVED] undefined reference to `MAIN_'

[sven2009]

Hi everyone,

one of the most often posted questions on the web - but none seem to answer my problem.

I am trying to compile with fortran (g95). Normal compiling works fine, preprocessing a .fpp doesn't. The following example shows that the b_message could be compiled no problem, but the b_system-linuxg95.fpp won't.

-------
Compiling module ./b_message (Rule 1)
/opt/g95-install/bin/x86_64-suse-linux-gnu-g95 -c -freal-loops ./b_message.f
ar: creating libinout-linuxg95.a
a - b_message.o
Pre-formatting module b_system
gawk -f ./preform.awk -v os=linux -v cp=g95 b_system.fpp >b_system-linuxg95.fpp
Preprocessing module b_system-linuxg95
/opt/g95-install/bin/x86_64-suse-linux-gnu-g95 b_system-linuxg95.fpp >b_system-linuxg95.f
/opt/g95-install/bin/../lib/gcc-lib/x86_64-suse-linux-gnu/4.0.3//libf95.a(main.o): In function `main':
main.c.text+0xa): undefined reference to `MAIN_'
make: *** [b_system-linuxg95.f] Fehler 1
------

any help would be GREATLY appreciated!!!!!!

cheers, sven

Found the cause:

Silly: I forgot the extra compiler option '-c' for the fpp. This allows subroutines to be compiled without a main program.

- need to contradict myself: the compiling didn't work after all.
No error was issued, but the resulting file is empty. So back to square one:

can anyone help?

thanks!

-E seems to work, but compilation still shows errors.
