[Gm2] Strange error message while compiling

[Martin Kalbfuß]

Hi,

I split up my source files into two separate files. Now I get a lot
error messages like

/home/martin/Desktop/SK/build/Al/libAl.a(Textout.c.o): In function
`bmp_read24':
Textout.c:(.text+0x0): multiple definition of `bmp_read24'

These functions aren't part of my lib. They are part of the allegro
libary, I link into the example program.

I link with -l:/usr/local/lib/liballeg-4.4.0
If I omit this parameter. It tells me still the same + a lot of
undefined reference errors.

So, this has nothing to do with the library liballeg-4.4.0.

Al I do, up to this point, is the inclusion of the allegro header file.

allegro.h

it's included in both files. But there are include guards, so this
shouldn't be a problem.

To be a bit more descriptive,

I create static library libAl.a with gcc, including both objects Al.c.o
and Textout.c.o

Then I link an example test.mod with this library and liballeg-4.4.0.

test.mod imports a definition module called Al.def. Maybe that's the
problem. There is only one definition module, but two separate
implementation files inside the static library. I'm not sure, if gm2
checks for this in any way. But it doesn't tells me, but only about the
double definitions. I thought, as long as I use a library, It isn't
important in which object, the implementation is, because gm2 doesn't
checks for matching module names.

I'm a bit confused, and not sure, how to proceed and if it's really a
bug.

Can anyone help?

Thanks,

Martin
