GNAT GPL 2009: Shared library project cannot import static library project?

GNAT GPL 2009: Shared library project cannot import static library project?

[AndreiK]

Hello everybody!

Can some body help me?
I have tryed to compile a shared library project using: "GPS 4.3.1
(20090114) hosted on pentium-mingw32msv & GNAT GPL 2009 (20090519)".

My shared library project imports a static library project and
compiler (gnatmake) raise an error: "Shared library project cannot
import static library project". Why???

Using the GNAT GPL 2008 with the same projects dont raise any errors.

Thank evrebody for you help.

Andrei

More exactly, I have used the next sequence of commands:
# gnatmake -c -gnatc  -PMyProject.gpr -d -XLegacy=Ada2005
# gnatdll -d ../libMyDLL.dll -e ./src/libMyDLL.def -I../obj -n ../obj/
mydll.ali

Thank everybody for possible assistance!

Perhaps because a shared library needs to be compiled to be position-
independent (-fPIC on some platforms) but a static library doesn't?

AdaCore continually improve error-detection.

Have you tried gprbuild? would (probably, I don't know Windows) know
how to run gnatdll.

It is a error condition not detected by GNAT GPL 2008.

[Per Sandberg]

Having a dynamic library importing a static library may lead to very 
"interesting" behavior of programs in a larger context, if there is any 
"static" data in the static library and therefore this is treated as an 
error by default with the GNAT tools.

This default behaviour could be supressed with switches to gprbuild if 
you know what you are doing and have read the manuals in depth and 
understand all the implications.
