Simple making links /usr/lib/nx/X11/Xinerama/libNX_Xinerama* - /usr/lib/nx/X11/Xinerama/libXinerama* don't work, because due to new build procedure libXinerama is linked against libNX_Xext and libNX_X11, not libXext and libX11. I don't know about the Xinerama/ subdirectory, it does not get installed by nx-libs. It is a X2Go patch. It enable support for more as one display (for example thinclients with multihead) But symlinking of /usr/lib/nx/X11/libXext.so.6 to /usr/lib/nx/X11/libNX_Xext.so.6 should work (talking about LD_LIBRARY_PATH- using programs) as long as the SONAME stays NX_Xext for automatic dependency finding of rpm (and perhaps deb?). It is wrong solution. Only (nx|x2go)agent should be linked against nx-libs. X-clients should be linked against system X libraries. Exception is libXinerama. Against this library should be linked both - agent and client. But in case of agent libXinerama should use libXext and libX11 from nx-libs and in case of clients it should use the same libraries from system. For this reasons we exporting LD_LIBRARY_PATH=/usr/lib/nx/X11 by start of agent and LD_LIBRARY_PATH=/usr/lib/nx/X11/Xinerama (*but not /usr/lib/nx/X11*) by start of desktop environment.

Every time the shared library ABI changes in a way that may break binaries [...] the SONAME of the library [...] should change. A heuristic that this change is done consistently is for example when the SO version is different from the package version (e.g. libgcrypt11 for libgcrypt-1.5.0). The antipole is that it's not done at all. So when the SO version == package version, it sure is going to raise some eyebrows, and perhaps jumping a gun when it cannot be established that the numbering is not a mistake (and with NoMachine being virtually unavailable...) ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev
