Statically compiling ICU on Linux?

ScottLupton

I wanted to statically link libicu on Linux because it causes a lot of dependency problems. The expected libraries are:

libicui18n.so.55 => not found
libicuuc.so.55 => not found
libicudata.so.55 => not found

libicu-dev comes with .a versions of these libraries for static linking:

/usr/lib/x86_64-linux-gnu/libicui18n.a
/usr/lib/x86_64-linux-gnu/libicuuc.a
/usr/lib/x86_64-linux-gnu/libicudata.a

I copied these files to a libicu folder in my development directory and then added these lines to my .pro file:

LIBS += ../libicu/libicui18n.a ../libicu/libicuuc.a ../libicu/libicudata.a
PRE_TARGETDEPS += "../libicu/libicui18n.a" "../libicu/libicuuc.a" "../libicu/libicudata.a"

Unfortunately, this doesn't work, and ldd shows that the resulting binary is still looking for libicu on the system.

How can I statically link libicu on Linux?

you have to compile Qt with those static libs, not your app...

I've rebuilt Qt with the three ICU libraries and that seems to have solved the problem.

Thanks for the help.
