So, is there a way to benefit from gp's great features to generate shared objects?

I can't speak for Solaris, but on Mac OS X it works. Note that you

have to build libgpc.a as

position independent code also, unless it's the default on the

platform (like it is on Mac OS X).

For sure I did. In fact, I use the shares object version of libgpc for my programs. The problem is not to produce shared objects with gpc (You gave me the way to do it on this mailing liste long time ago). My question was about using gp on top of gpc to produce shared objects.

What's the output of gp with -v ?

Here it is.

<snip>

Hm, could the problem be that no linking is occuring ? I think that's

the default for gp when

compiling a unit into a shared library. I have a patch for gp that

adds --compile-and-link. When

passing that option, linking will occur.

Adriaan van Os

Yeah! Your patch works perfectly. I can now generate shared object with gp.

Thank you very much for your continuous and invaluable help!

Kind regards,

Have you tried using gp's --Pascal=OPTION parameter form to tell gp to pass the --shared and -fPIC options onto each invocation of gpc?

Gale Paeper gpaeper@empirenet.com

Yes I did - with no success however.

I tried: --executable-file-name=mod1.so -o mod1.so --Pascal=--shared --Pascal=fPIC

and some combinations of the above but gp never generates a shared object.
