Description Mark McKenna 2005-11-25 19:42:25 UTC
When emerging glibc-2.3.5-r3, if any element of LD_LIBRARY_PATH contains a dot
anywhere within it, glibc thinks the current directory is in it and dumps out.

The workaround is pretty simple; just remove these elements from the path;
however I woudn't want to be around if I needed something at the other end of
that path.

Reproducible: Always
Steps to Reproduce:
1. LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/root/.local/lib"
2. emerge glibc
3. watch

Actual Results:  
glibc refused to compile, thinking that '.' (the current directory) was in the path.

Expected Results:  
I'm thinking a pattern match along the lines of /(:.:|^.:|:.$)/.

Comment 1 SpanKY gentoo-dev 2005-11-26 01:46:02 UTC
having an empty path ("") in LD_LIBRARY_PATH has the same exact meaning as "."
Comment 2 Mark McKenna 2005-12-02 16:29:15 UTC
It wasn't empty, since when I removed the instance of '.local' from the path it
started working.
Comment 3 SpanKY gentoo-dev 2005-12-02 16:41:30 UTC
post the output of glibc going boom please
Comment 4 SpanKY gentoo-dev 2005-12-20 15:30:27 UTC
i'm unable to reproduce this

if you do:
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/root/.local/lib"
and LD_LIBRARY_PATH is empty, then you end up with:
:/root/.local/lib
and that is wrong

i reviewed the configure.in script and the logic in it is correct ... also,
this worked just fine for me:
LD_LIBRARY_PATH=/root/.local/lib emerge ~glibc-2.3.5
but this (predictably) failed:
LD_LIBRARY_PATH=:/root/.local/lib emerge ~glibc-2.3.5
