0000418: No user interface (Cmdenv, Tkenv, etc.) found when compiling with GCC 4.6 in Ubuntu 11.10

Notes
(0000572) rhornig (administrator) 2011-10-19 12:14	gcc 4.6 does not add the shared lib to the executable if no symbols from it are referenced. This is a deviation from earlier gcc behavior (they always added the shared library). gcc 4.6 adds the --as-needed option to the linker (ld) command line so we need to turn that off. Fix: add --no-as-needed in front of the library

(0000573) rhornig (administrator) 2011-10-19 12:16	Workaround for omnetpp 4.1: In Makefile.inc.in find the following lines (towards the end): CMDENV_LIBS = -u _cmdenv_lib -loppcmdenv$D -loppenvir$D TKENV_LIBS = -u _tkenv_lib -lopptkenv$D -loppenvir$D -lopplayout$D and replace them with: CMDENV_LIBS = -u _cmdenv_lib -Wl,--no-as-needed -loppcmdenv$D -loppenvir$D TKENV_LIBS = -u _tkenv_lib -Wl,--no-as-needed -lopptkenv$D -loppenvir$D -lopplayout$D then ./configure make clean make
