Hi,
I’ve read the article on deployment to X11 platforms [qt-project.org] but there are a couple of things that remain unclear to me.
Can I statically link to libraries even if my Qt build is not static? I thought so, and added
QMAKE_LFLAGS += -static-libstdc++ -static-libgcc
unix|win32: LIBS += -lstdc++
to my project file, but running the “ldd” command still gives me the following:
linux-gate.so.1 => (0xb772f000)

(tried to bold the relevant line above, but seems to not work with code tags, it’s sixth from the top)
Which also brings me to my next question. Logic dictates that all the Qt5.0.2 libraries will obviously have to be distributed along with the executable, but is there a way to determine which of the libraries in the “i386-linux-gnu” paths (be they /usr or /lib paths) can be excluded?
It isn’t very important to get this right, I have no qualms with distributing all of it, but was interested as a learning exercise.
I’m running 32-bit Ubuntu 12.04
Any pointers will be appreciated.
Thanks!
