[FIXED] "not found (try using -rpath or -rpath-link)" during cross compilation
Sat, 03 Jan 2015 17:58:13 +0000

linuxWhen you see the following kind of errors during cross compilation (linking phase): ld: warning: libfontconfig.so.1, needed by .../libQtGui.so, not found (try using -rpath or -rpath-link) ld: warning: libaudio.so.2, needed by .../libQtGui.so, not found (try using -rpath or -rpath-link) There could be two reasons:

  • the list of required binaries is not complete and linker cannot complete the linking automatically
  • your $SYSROOT/usr/lib is not passed to linker by -rpath-link as mentioned in error message

During normal native build your libraries are stored in standard locations (/usr/lib) and locating libraries is easier. Cross compilation needs more attention in this ares as SYSROOT is not standard.

Then search for LDFLAGS setup in your build scripts: LDFLAGS="-L${STAGING_LIBDIR}" And change to the following: LDFLAGS="-Wl,-rpath-link,${STAGING_LIBDIR}-L${STAGING_LIBDIR}" The clumsy syntax -Wl,<options-with-comma-as-space> tells your compiler (that is used for linking purposes) to pass the options (with commas replaced by spaces of course) to linker (ld).
