I don't know if there's a plan to support the newer Solaris' distros but sip-router and Kamailio 3.0 don't compile on OpenSolaris with SunStudio Compiler (cc) or GCC. Kamailio up to 1.5 has historically compiled at least with GCC - it seems to be Makefile related. --- When the CC variable is set to point to SunStudio (/opt/SunStudioExpress/bin/cc) I get: Makefile:248: config.mak: No such file or directory normal Makefile.defs exec Makefile.defs:380: Unknown compiler /opt/SunStudioExpress/bin/cc\; supported compilers: gcc, sun cc, intel icc target architecture <x86_64>, host architecture <x86_64> Makefile.defs:933: *** Unsupported compiler (/opt/SunStudioExpress/bin/cc:/opt/SunStudioExpress/bin/cc), try gcc. Stop. --- If I set it to GCC 4.3.2 I get the following when I make (or gmake, although OpenSolaris generally defaults to GNU make): Makefile:248: config.mak: No such file or directory normal Makefile.defs exec target architecture <i386>, host architecture <x86_64> And things just stop - I never get a prompt back until I ctrl-x. --- I'm attempting the compile as root so there aren't and permissions issues. And suggestions would be most appreciated. -Nick
