crosstool-NG build for powerpc on Fedora Core 11 = hundreds of grep processes

[Mark Schaefer]

Hi all,

The subject mainly covers it...

Here's my process:
   ./configure --local
   make
   ./ct-ng build

at this point, top shows no significant activity, but script is acting slowly.

If I interrupt (^C), I get the following output:

[INFO ]  Performing some trivial sanity checks
[00:00] / ^Cmake: *** [build] Interrupt

Now, ct-ng has spawned off so many grep jobs that I get the following:

[mschaefe@grumpy crosstool-ng.1.5.0]$ ps
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
[mschaefe@grumpy crosstool-ng.1.5.0]$ ps
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable

When I finally get a ps, I get a page full of entries like this:

Since there's a known issue on ccache, here is some more detail:  It
seems as though ccache is now a directory rather than an executable.
Is that a problem?  Notice that the processes are 6 PIDs apart, which
suggests that there are some steps being executed non-recursively in
the middle.

[mschaefe@grumpy crosstool-ng.1.5.0]$ ls -l /usr/bin/ccache

Please help :)

Thanks!
