Bug 12613 – cpp still a problem

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Artur Brodowski 2002-12-23 05:06:59 UTC]

hello,

since gnome team does not pack latest unstable gnome releases, i thought
i'll try garnome. when compiling i encountered this really strange problem,
when cpp creates lots and lots of new processes, until compilation crashes
with 'too many open files in system' error.
i thought it was garnome problem at first, but today i tried to upgrade 
gcc and same thing happens - there were about 200 cpp processes at one time!
i'm not really sure what's causing the problem, but cpp overload happens
when imake is run during compilation.

my emerge info:
Portage 2.0.46-r2 (default-x86-1.4, gcc-3.2.1, glibc-2.3.1-r2)

az: is this the /usr/bin/cpp linkage problem ?

[Comment 2 Martin Schlemmer (RETIRED) 2002-12-23 12:04:30 UTC]

Nope, /lib/cpp.  Please past the output of:

  # ls -l /lib/cpp /usr/bin/cc /usr/bin/cpp
  # which gcc
  # which cpp
  # emerge gentoolkit; epm -q gcc

(dont include the output of 'emerge gentoolkit' ... )

[Comment 3 Artur Brodowski 2002-12-24 03:00:56 UTC]

here it goes:

root@tool bzd # ls -l /lib/cpp /usr/bin/cc /usr/bin/cpp
-rwxr-xr-x    1 root     root           20 2002-12-23 10:56 /lib/cpp
-rwxr-xr-x    1 root     root           20 2002-12-23 10:56 /usr/bin/cc
-rwxr-xr-x    1 root     root          303 2002-12-23 10:56 /usr/bin/cpp
root@tool bzd # which gcc
/usr/bin/gcc
root@tool bzd # which cpp
/usr/bin/cpp
root@tool bzd # epm -q gcc
gcc-3.2.1

i just noticed, that it is not imake prob, but cpp itself:
cpp -h
also hangs - creates new processes over and over, no output.

Artur, I think you might have the portage/gcc issue.  Please go to
http://cvs.gentoo.org/~seemant

[Comment 5 Artur Brodowski 2002-12-24 04:59:44 UTC]

thanks Seemant, i guess that was the problem.
since i couldn't compile gcc (cpp blocked the resources at some point)
i had to use downloaded .tbz2. cpp works now, i'm gonna recompile gcc
and portage soon.
resolving this i guess.
merry xmas ;)

[Comment 6 Artur Brodowski 2003-01-09 06:11:07 UTC]

hello.
i cannot recompile gcc (3.2.1-r6 just got to stable), cpp hangs same as
before. i can't really tell what caused the problem - i emerged few things
and everything went smooth; when emerging gcc it kills the system 
producing cpp processes over and over. 
i'm going to fix gcc just like i did last time, but this is really wicked;
could it be binutils issue? or portage?

[Comment 7 Martin Schlemmer (RETIRED) 2003-01-12 14:36:34 UTC]

Check if cpp is a text file/script, if so, please include ...

[Comment 8 Martin Schlemmer (RETIRED) 2003-01-17 05:14:52 UTC]

Try with gcc-config-1.3.0.

[Comment 9 Artur Brodowski 2003-01-17 05:20:58 UTC]

thanks, it helped.
i'm marking this fixed, although i'm not sure what was really broken
(only effects) and have no idea how it was fixed ;-D
best regards,
artb.
