Hello, - I'm trying to test squid 3.2.0.15 on Solaris 10, but compiling 3.2.0.15 with SunStudio 12.3 produces the following error at link fase: Undefined first referenced symbol in file CommCloseCbPtrFun::CommCloseCbPtrFun(void(*)(const CommCloseCbParams&),const CommCloseCbParams&) ./.libs/libsquid.a(comm.o) CommTimeoutCbPtrFun::CommTimeoutCbPtrFun(void(*)(const CommTimeoutCbParams&),const CommTimeoutCbParams&) client_side.o void Ipc::TypedMsgHdr::putInt(int) libIpcIo.a(IpcIoFile.o) FdeCbPtrFun::FdeCbPtrFun(void(*)(const FdeCbParams&),const FdeCbParams&) ./.libs/libsquid.a(comm.o) void String::append(const char) ConfigParser.o ld: fatal: symbol referencing errors. No output written to squid libtool: link: rm -f ".libs/squidS.o" make[3]: *** [squid] Error 2 any clue what could be the root cause of this problem? Kind Regards, CA,
