no, that does not work.... here is the output from my `configure` with that suggestion: checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes ...... Notice how it does not look for mips-elf-gcc. I looked at the 'configure' script generated and it does need the other settings of 'ac_tool_prefix' and 'cross_compiling' due to the location of the variables in the generated 'configure' Try it with a simple two line 'configure.ac' AC_INIT host_alias=mips-elf No, I don't want my site defaults to be cross-compiled by default. Yes, this source code will only work on a very specific MIPS. Thanks.
