From: AndreiK on 19 Jan 2010 13:02 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

Why??? Perhaps because a shared library needs to be compiled to be position- independent (-fPIC on some platforms) but a static library doesn't? > > Using the GNAT GPL 2008 with the same projects dont raise any errors.

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. /Per 2010-01-19 19:02, AndreiK skrev: > 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".
