cygwin -> mips GCC_NO_EXECUTABLES error

Wed Sep 6 01:57:00 GMT 2006

i could not get glibc-2.4 to compile with the current nptl patch, same
problem (which --disable-multilib does not fix), and others (im using
ppc860 though).

i have only had success with glibc-2.3.6 and earlier.

also, the ports addon does not work for me if im using nptl...

try 2.3.6 w/o ports.

my other recommendation would be to avoid cygwin at all costs when trying
to initially build your first tool chain, in particular glibc.

just build a linux machine, get it working, then go to cygwin.

at worst, if you can get cygwin to build gcc (but not glibc), you can
then copy glibc binaries from your linux machine and call it a day.

for reference here is my powerpc-860-linux-gnu.crosstoolconfig.txt
