Confirmed. Seems that there is a version mismatch in libnl. Don't know which of the 2 is good Look at this, libnl-3 reports version 0.28: $ pkg-config libnl-3 --version 0.28 But in wireshark configure.ac there is this, checking for libnl-3 3.0: PKG_CHECK_MODULES(LIBNL3, [libnl-route-3.0 >= 3.0 libnl-genl-3.0] >= 3.0, [have_libnl3=yes], [have_libnl3=no]) This fixes this issue (followed by an autoconf call): # diff -u configure.ac.old configure.ac --- configure.ac.old 2013-05-04 07:37:32.805362134 +0200 +++ configure.ac 2013-05-04 07:37:46.325644052 +0200 @@ -300,7 +300,7 @@ # was requested by the user. # if test x$libnl_version = "xany" -o x$libnl_version = "x3"; then - PKG_CHECK_MODULES(LIBNL3, [libnl-route-3.0 >= 3.0 libnl-genl-3.0] >= 3.0, [have_libnl3=yes], [have_libnl3=no]) + PKG_CHECK_MODULES(LIBNL3, [libnl-route-3.0 >= 3.0 libnl-genl-3.0] >= 0.28, [have_libnl3=yes], [have_libnl3=no]) fi if test x$libnl_version = "xany" -o x$libnl_version = "x2"; then PKG_CHECK_MODULES(LIBNL2, libnl-2.0 >= 2.0, [have_libnl2=yes], [have_libnl2=no])

I believe this is only happening with USE="-ssl" on wireshark, can you guys confirm that?
(In reply to comment #8) > I believe this is only happening with USE="-ssl" on wireshark, can you guys > confirm that? Confirmed.
I think there is a bug in configure.ac somewhere. The tests being run by ./configure for libnl do not report any errors, but still come out with a "failed" status. If I try to manually run the same pkg-config commands, it finds libnl perfectly. FYI to simplify troubleshooting, this can be triggered outside emerge with "./configure --with-libnl --without-gnutls".
(In reply to comment #10) > I think there is a bug in configure.ac somewhere. Yes.
This bug seems to have existed since libnl was very first given a ./configure option in this commit: http://anonsvn.wireshark.org/viewvc/trunk/configure.ac?r1=48307&r2=48395 At that point it was given a --enable-libnl option (versus --with-libnl it has now), and I get the following results: # ./configure --enable-libnl ... Use nl library : yes (v3) # ./configure --enable-libnl --without-gnutls ... Use nl library : no
Actually, it's been broken in this way since libnl support (configure autodetection) was first added in r43375 in June 2012, so not quite a brand new regression.

Something is wrong in configure.ac, but this isn't it. It probably comes down to a namespace collision between different tests' variables.
Well --enable-libnl was only valid for r48395, the first commit with non-autodetect libnl usage. It does work as I used it there. BUT you're right that this isn't relevant. If you go back to r43375 where libnl support was added, still using only autodetection, the autodetection fails when gnutls is disabled. So --without-gnutls has broken libnl use since the beginning. r43375 tests: # ./configure ... Use nl library : yes (v3) # ./configure --without-gnutls ... Use nl library : no
The problem is that PKG_PROG_PKG_CONFIG is only expanded once, so if you call it PKG_CHECK_MODULES conditionally the first time, as pkg.m4 helpfully explains, you have to explicitly invoke PKG_PROG_PKG_CONFIG before using PKG_CHECK_MODULES.
Accepted upstream.
