I have been running CCSV5.4 under Linux Mint 15 (with much difficulty, but finally working successfully). During the process of trying to get it working, I saw V5.5 was out so downloaded and installed into a separate directory tree. Now that V5.4 works I tried V5.5 again but it still gives the same error when trying to launch debugging:
/opt/tiv55/ccsv5/ccs_base/DebugServer/drivers/libstellaris_emu.so: libxpcom.so: cannot open shared object file: No such file or directory
I checked and libstellaris_emu.so exists in that directory. libxpcom.so exists in /opt/tiv55/ccsv5/eclipse/xulrunner/
