    copying to the same dir only works on windows, not on linux.

      I saw that below with another project. What exactly is that? shared would need some *.so? But there's only the executable shipped.

      LNFLAGS+=-shared -rdynamic -nodefaultlibs -m32 -ggdb -L/usr/lib32 -L../libavionics -L../libogl -L$(LUAJIT)/lib

        MinGW is a port of GCC - Gnu Compiler Collection to Microsoft Windows. Just Check your configuration process..

            the author told me that i dont need to link wheter static nor dynamic and hence no gpl problem....

            http://www.osnews.com/story/24557/Torvalds_Android_GPL_Claims_Totally_Bogus_

            "It seems totally bogus. We've always made it very clear that the kernel system call interfaces do not in any way result in a derived work as per the GPL, and the kernel details are exported through the kernel headers to all the normal glibc interfaces too. ... If it's some desperate cry for attention by somebody, I just wish those people would release their own sex tapes or something, rather than drag the Linux kernel into their sordid world."

              So, you want to use the kernel system call interface? Or what do you want to tell us with the link? In the case of the linux kernel headers, the (legal) situation is kinda special, because they contain merely the definition of an interface to interact with the kernel. Is the library you want to use a headers only library?

                have a look at the link to vascore below. I was told that no linking is needed as communication would be alike the link posted above.

                    Hi mike4,

                    there are 3 possibilities:

                    you use plain C functions. Then you can use late binding and QLibbrary::resolve

                    you want to use C++ classes, then you must use early binding and link against the library

                    you combine them through the use of interfaces and creator functions. But then the interfaces must be pure interfaces.

                      Hi
                      now i simply want to compile/run the main.cpp in the root folder and get:

                      dlerror:/apps/X-Plane/Aircraft/General Aviation/Paa/alal/plugins/fmc/lin.xpl: undefined symbol: _ZN9FMSSystemC1Ev

                      Compilation is ok without linking. So i cannot link for GPL reasons but what am i doing then? And why do i get the above error if i don't have to link?
                      The lib is compiled and copied into the same folder as the plugin(main.cpp; x-plane plugin) above. Either the lib as the plugin are shared libs.
                      Thanks again
                      Michael
