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

[Mark Schaefer-3]

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:
ps ax

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.

Please help :)

Mark,
All,

If I do exactly that, then here's what I get:
  # ./configure --local
  # make
  # ./ct-ng build
  There is no existing .config file!
  You need to either run 'menuconfig',
  or configure an existing sample.
  make: *** [.config] Error 1
  #

So, I guess you did configure it (./ct-ng menuconfig) before you run the
actual build, right?

None of the crosstool-NG scripts call grep with '-qw'.

The only solution I know of right now is to de-install ccache.

Hi again,

You're correct, I did a menuconfig prior to that.  And thanks,
de-installing ccache did the trick.  I should have tried that first
before posting.

Thanks,

Mark
