Hello Jonas,

At first, thank you for your reply.

It is really not easy, because my project I am just fighting with has
about two thousands units/forms.

I have longer time a difficulty to solve this message when I try to
build fpc with "sudo make clean all":

Makefile:2279: *** No libgdb.a found, supply NOGDB=1 to disable
debugger support.

of course, then I use "sudo make clean all NOGDB=1" and it builds
fine, but without debugger support I need.

I am a newbie to MacOSX 10.5 and therefore I would like to ask how to
install libgdb.a library which is requested.

Thanks for any reply in advance.
