This bug is still present in 4.2.1 but now happens on both fc5 and fc6


still remains the two line script

----    here be script
exec  "$@"
-----    there was script
Comment 4 Marty Fouts 2007-07-24 05:17:25 UTC
OK, so this one's weird and starts out as a user error.

If the path specified in --prefix=/usr/local/armdev-$CPU-4.2.0 in the original config is *not* writable by the account running the build, the make all-gcc fails with the bizarre error indicated in the original bug report.

If the path specified *is* writable, then the build finishes just fine.

Comment 5 Alex Cornejo 2007-12-12 23:43:51 UTC
I have a similar bug, so I am posting here (otherwise I can open a new bug).

I run:
./configure --target=mipsel-semb-elf --prefix=/scratch/semb/semb/ --disable-libssp --with-newlib --enable-languages=c --disable-threads --disable-shared --without-include-headers

Then make fails with the following:

          MULTILIB_CFLAGS="" T= crtbegin.o crtend.o crti.o crtn.o
make[4]: Entering directory `/scratch/semb/gcc-4.2.2/host-i686-pc-linux-gnu/gcc'

          -o crtbegin.o
exec: 2: -G: not found
make[4]: *** [crtbegin.o] Error 1

I am running on Ubuntu (in case that maters). This seems to be a bug, since this command runs properly on gcc-4.1 (just downloaded a fresh copy and tested it).
Comment 6 Alex 2008-02-05 00:14:24 UTC
I have the same problem: line 2: exec: -m: invalid option

Trying to build 4.2, the directory specified in --prefix *is* writable by the user running the build.
Comment 7 Ramana Radhakrishnan 2009-04-19 22:02:36 UTC
This doesn't appear with any of the release branches (4.3, 4.4) or trunk currently. Can this now be closed out ?
Comment 8 Richard Earnshaw 2009-12-10 22:54:41 UTC
No feedback in 6 months.  Closing...
