I tried to install xrooms on a Sun4, OS 4.0.3, X11R4, but I get the following problem: cc -o xrooms xrMain.o xrSetup.o xrGen.o xrApp.o xrXawUI.o xrXawRoom.o xrNames .o xrProfile.o xrProto.o xrProtoArgs.o xrProtoIter.o xrDoProto.o xrActions.o xrXUtils.o xrDebug.o -g ../lib/librooms.a ../utils/libutils.a -lXaw -lXmu -lXt -lX11 -lm -lXext ld: Undefined symbol _alloca *** Error code 1 make: Fatal error: Command failed for target `xrooms' Any idea where is this symbol defined?

"/usr/include/alloca.h": /* @(#)alloca.h 1.3 88/02/07 SMI */ #if defined(sparc) # define alloca(x) __builtin_alloca(x) #endif Basically, you need to find those source files that call "alloca" and put in something like #ifdef sparc #include <alloca.h> #endif at the front of them. Be warned that some other compilers also need assistance in coping with "alloca"....
