If qtsupport and qtbase are different repositories, then you need to install from one so that the other may find it. But you need not deploy the static libraries to your device, final installation of Qt, or along with your program. No Linux distribution should be affected, since those support libraries are already present in their systems. > I'm probably having a pre-coffee moment, but you lost me on the "whole > archive linkage" bit. ;) gcc -o libfoo.so -shared foo1.o libstatic.a That does *not* link properly. First, you need to add -Wl,--no-undefined, which we already do. That might be enough, since we everything we need from libstatic.a is carried in from symbol dependencies (from foo1.o). If that does not work, we need -Wl,--whole-archive libstatic.a -Wl,--no-whole-archive That will cause all .o contained in the static archive to be linked into the final binary (the ELF shared library), regardless of whether they were required by symbol dependencies. This is mostly needed if the static archive contains API. I have no clue how or even *if* that works with non-GNU linkers. Someone needs to test Mac OS X's linker and MSVC, at minimum, and hopefully check also Solaris's and AIX's. Finally, note that compiling Qt in static mode will require a different code path. Since there's no actual linking involved, the .o contained in lbstatic.a need to be extracted and then re-added into libfoo.a. Hence the "I'm not volunteering" part. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358
