Unfortunately I haven't a clue about where and how the 'libgmon.a' should be built -- the ARM-support in 'newlib-1.x.y/newlib/libc/arm' (this is the replacement for the 'libgloss/arm') doesn't seem to have any support for profiling... > Is it normal that for arm targets libgloss configuration fails... ?

Looking at the Intel/RedHat XScale/StrongARM GNUPro-distributions, the 'bsp'-packages etc. could be recommended. Perhaps the profiling support is available there... ------------------------------ clip ------------------------------------------ Fri Jul 6 17:46:11 EDT 2001 GNUpro tools for the Intel X-Scale Microarchitecture are now hosted by Intel. http://developer.intel.com/design/intelxscale/dev_tools/ Redboot Debug Monitor for the Intel® IQ80310 board, Version 1.0 ftp://download.intel.com/design/intelxscale/dev_tools/redboot-bin.tar.Z http://developer.intel.com/design/intelxscale/dev_tools/redboot-bin.tar.Z Redboot Debug Monitor source code for the Intel® IQ80310 board, Version 1.0 ftp://download.intel.com/design/intelxscale/dev_tools/redboot-src.tar.Z http://developer.intel.com/design/intelxscale/dev_tools/redboot-src.tar.Z GNUpro Toolkit Getting Started Guide ftp://download.intel.com/design/intelxscale/dev_tools/xscalestart.pdf http://developer.intel.com/design/intelxscale/dev_tools/xscalestart.pdf GNUpro for Windows NT hosts - COFF ftp://download.intel.com/design/intelxscale/dev_tools/i686-pc-cygwin-x-xscale-coff.zip http://developer.intel.com/design/intelxscale/dev_tools/i686-pc-cygwin-x-xscale-coff.zip GNUpro for Windows NT hosts - ELF ftp://download.intel.com/design/intelxscale/dev_tools/i686-pc-cygwin-x-xsccale-elf.zip http://developer.intel.com/design/intelxscale/dev_tools/i686-pc-cygwin-x-xsccale-elf.zip ------------------------------ clip ------------------------------------------ The 'experimental' contains toolsets for StrongARM. In any case these prebuilt tools can provide a nice reference for those self-built ARM-tools. Or any of those downloadable 'arm-elf'-toolsets for Win32-host on the net may have info about this thing. Searching the archives of this maillist should give the addresses... Cheers, Kai ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe?
