Hi Jim,

base_libs.spec is the one you probably need to get fixed (it's rare to actually build glibc, the preference is to use the components out of the toolchain).

Anyhow, can you try changing the _expression_ to:

Hi Staurt,

Yes.  That works, but I used just 'text' instead in my patch.  The test is really just a safety check to make sure its a text file.  Only a hand full of files are explicitly being manipulated in each of the two spec file.  A broader check would make it a bit more future proof in case some one decides to tweak the magic file description again.

perl -w -e '

    @ARGV = grep { `file $_` =~ m,ASCII (?:C program|English) text, } @ARGV;

    exit(0) unless @ARGV;

    $^I = ".bak";

    while(<>) {

        s,[\S/]+/,,g if m,^GROUP,;

        print;

    }

Let me know if this works.

Regards, Stuart

PS.  I forgot it's in the dist/lfs-5.1/base_libs/base_libs.spec file too.

I started to have this issue when I moved from RedHat 4.x to Fedora 16.  I found a couple different archived emails about it but they never seemed to track down the real issue.  If it was resolved, then please forgive the email.

I tracked it to dist/lfs-5.1/glibc/glibc.spec:

perl -w -e '

    @ARGV = grep { `file $_` =~ m,ASCII C program text, } @ARGV;

    exit(0) unless @ARGV;

    $^I = ".bak";

    while(<>) {

        s,[\S/]+/,,g if m,^GROUP,;

        print;

    }

...

The 'file' command returns different results for these platforms:

RedHat Enterprise 4.x:  $ file rootfs/usr/lib/libpthread.so  

rootfs/usr/lib/libpthread.so: ASCII C program text

Fedora 16: $ file rootfs/usr/lib/libpthread.so 

rootfs/usr/lib/libpthread.so: ASCII English text

The above code therefore doesn't match on the Fedora 16 and never removes any of the offending absolute paths from the text search files.
