I have successfully built the toolchain but have hit a problem compiling the actual code concerning multiply defined assembler macros. The error appears while compiling an assembler file context.S, and the macros themselves in cyg/hal/arch.inc, for example: .macro lwi reg,val .macro hal_fpu_load regs I'm aware that as I compile three separate copies of this arch.inc exist on my machine: - the original one in the ecos_repository/packages tree - the one copied to my app source tree (with other kernel headers) by the ecosconfig tool for compiling my application - the one present in the headers gnutools/powerpc-eabi/sys-include tree for building the cross-compiler Since the include file is assembler and not guarded, my guess is that it's somehow being included twice. Can anyone suggest what might be wrong with my setup to cause this, or what the cause might be if not this? I append an error trace below Thanks Leo powerpc-eabi-gcc -c -I/home/leok/dev/projects/architectural/ecos_kernel/full/install/include -I/home/leok/ecos_repository/packages/hal/powerpc/arch/v2_0_26 -I/home/leok/ecos_repository/packages/hal/powerpc/arch/v2_0_26/src -I/home/leok/ecos_repository/packages/hal/powerpc/arch/v2_0_26/tests -I. -I/home/leok/ecos_repository/packages/hal/powerpc/arch/v2_0_26/src/ -finline-limit=7000 -msoft-float -mcpu=860 -Wall -Wpointer-arith -Wstrict-prototypes -Winline -Wundef -g -ffunction-sections -fdata-sections -fno-exceptions -Wp,-MD,src/context.tmp -o src/hal_powerpc_arch_context.o /home/leok/ecos_repository/packages/hal/powerpc/arch/v2_0_26/src/context.S /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc: Assembler messages: /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc:140: Error: Macro with this name was already defined /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc:171: Error: Macro with this name was already defined /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc:181: Error: Macro with this name was already defined /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc:197: Error: Macro with this name was already defined /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc:207: Error: Macro with this name was already defined /home/leok/dev/projects/architectural/ecos_kernel/full/install/include/cyg/hal/arch.inc:218: Error: Macro with this name was already defined make[1]: *** [src/context.o.d] Error 1 make[1]: Leaving directory `/home/leok/dev/projects/architectural/ecos_kernel/full/hal/powerpc/arch/v2_0_26' -- Leo Nitin Khale leo@raceoddity.net "I expect history will be kind to me, since I intend to write it." - Winston Churchill -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
