I have a Linux deployment questions: How can i link my app statically with the standard C++ library ( note that i built Qt as a static lib ) ? In the documentation for "Deploying an Application on Qt/X11" whose file path is "/doc/html/deployment-x11.html" In the Application Dependencies section it is stated that: "This will list all the shared library dependencies for your application. Depending on configuration, these libraries must be redistributed along with your application. In particular, the standard C++ library must be redistributed if you're compiling your application with a compiler that is binary incompatible with the system compiler. When possible, the safest solution is to link against these libraries statically." Any help appreciated. Thank you ! -- [ signature omitted ]

I haven't done this with the standard C++ library yet, but I did so
with libusb. I _guess_ it should work the same way for libstdc++. Just
add the .a file when linking. You can do this by simply adding it to
the LIBS variable without adding the -l prefix.
I'm doing it with this snipped in my .pro file (note that I use
-config static for a static build):
unix:static {
# force statically linking of libusb. Use gcc to get its path.
# if you have libusb.a in a non-standard lib path add it to
# the INCLUDEPATH variable above.
LIBS += $$system($$QMAKE_CC $$INCLUDEPATH -print-file-name=libusb.a)
}
If someone knows a nicer solution please let me know :)

That's how we are doing. Our pro-file looks something like this:
unix:!mac:release {
LIBS += -Wl,-Bstatic $$BZIP2_LIBS $$KRB5_LIBS -Wl,-Bdynamic
$$SOUND_LIBS -lcom_err -lresolv
}
as Qt adds it's libraries last, we still dynamically as we end our
static libs with -Wl,-Bdynamic.
