downloadrtems-cce81a748fc4f69de944ff0ae8cb1a59b6194308.tar.bz2
A patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:
Here is another patch to hopefully enhance rtems' configuration. Motivation: Try to support other c-compilers besides gcc (I tried to build rtems under Solaris using sun's WSPro c-compiler). Here is a couple of small patches concerning the host compiler configuration, which fix/work-around the worst problems when using sun's WSPro c-compiler. Changes: * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie. gcc.cfg is generated by configure now. * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix). * Add -g to host compiler flags only if configure reported -g to work * Add -Wall to host compiler flags only if configure reported that the host compiler is gcc (WSPro's cc chokes on -Wall). * Some modifications to make/Makefile.in * Adapted make/custom/default.cfg to the new location of gcc.cfg BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS etc.) which deserves to be cleaned up, IMO. IMO, a similar patch should be applied to gcc-target-default.cfg
