Hi, I am trying to upgrade gcc from 2.95.3 to 3.4.5 on vxWorks. The target processors are power PC - MPC 8260, 8360, 860, 850 ,7410... . I am facing few problems. I have re-compiled all the bootroms on these targets, and also recompiled (WIND_BASE)/target/src directory. 1. Do I need to recompile lib$(CPU)$(TOOL)vx.a ? 2. Do I need to recompile libgcc.a ? 3. Are there any header files like stdarg.h that are going to change with new compiler ? I could successfully build , burn and bring up bootrom_uncmp - uncompressed images on these targets. But when I convert them to bootrom.bin - compressed images, somewhere it is lost. The processor hangs on some branch instruction and the emulator goes for reset. Here is the make sequence I execute. clearmake -C gnu bootram $(WIND_BASE)/host/sun4-solaris2/bin/elfToBin < bootram > bootram.bin $(WIND_BASE)/host/sun4-solaris2/bin/deflate < bootram.bin > tmp.Z $(WIND_BASE)//host/sun4-solaris2/bin/binToAsm tmp.Z >bootrom.Z.s clearmake -C gnu bootrom objcopyppc -O bootrom bootrom.bin But the board goes for reset on some branch instruction. I am not sure if something went wrong in deflating the image. But the uncompressed image comes up successfully on the board. Do we need the following tools separately for new compiler from vxworks ? - binToAsm , deflate , elfToBin, elfXsyms ,romsize , vxsize thanks aparna
