Description qdii 2013-06-09 09:17:08 UTC

When compiling busybox from the main repository, it failed during link with "cannot find -l-pthread". 

Reproducible: Always

Steps to Reproduce:
1. emerge sys-apps/busybox-1.21.0
2.
3.
Actual Results:  
Link fails with "cannot find -l-pthread"

Expected Results:  
Compilation should create a binary executable.

WORKAROUND: Replacing "-l-pthread" with "-pthread" in the final link command line fixes the problem.

Please note that I was compiling a SELinux Gentoo from scratch when this occurred.

doubt it's related to pam

post the output from running:
 for p in libpcre libselinux libsepol ; do
  echo $p
  pkg-config --libs $p
  pkg-config --cflags $p
 done

Not the same poster but I have the same problem, here is the output of the command.
libpcre
-lpcre 

libselinux
-lselinux 

libsepol
-lsepol

I have no idea from where '-pthreads' comes from (it should be pthreads), but scripts/trylink can fix it.

scripts/trylink line 120:
-l_list=`echo "$LDLIBS" | sed -e 's/ / -l/g' -e 's/^/-l/' -e 's/^-l$//'`
+l_list=`echo "$LDLIBS" | sed -e 's/ -/ /g' -e 's/ / -l/g' -e 's/^/-l/' -e 's/^-l$//'`
