Autoconf fails to detect the resolver library, this prevents MTR from building. A 'fix' is to patch the generated configure script to correctly detect the resolver library. However, this may break when used with older versions of libresolv (tested with libresolv-2.3.4). See attached patch file, and bug #54018. Reproducible: Always Steps to Reproduce: 1. Add amd64 keyword to /usr/portage/net-analyzer/mtr/mtr-0.54-r1.ebuild 2. emerge mtr Actual Results: checking for res_mkquery... no checking for res_mkquery in -lbind... no checking for res_mkquery in -lresolv... no configure: error: No resolver library found Expected Results: Detected the presence of libresolv, and compiled/installed.

Created attachment 33339 [details, diff] Patch for configure Changes res_mkquery to __res_mkquery in code for checking for presence of libresolv
Bug #54018 relates to Autoconf problem.
a simpled sed -i -e "s/res_mkquery/__&/g" configure.in autoconf does it too. The questions are: (a) to what version of libresolv does this apply and how can we test on them ? (b) does this also apply to other resolvers too ? Further: the ipv6 patch seems not to do his job properly. I couldn't emerge mtr with USE="ipv6" due to linker problems. (Missing symbols) Further2: this is no amd64 bug... reassigning to bugwranglers (couldn't find the appropriate bug owner... bte: mtr has no metadata.xml!)
*** Bug 54193 has been marked as a duplicate of this bug. ***
This fix solves the problem for me. Thanks. If I can provide additional information to help you, please let me know.
mtr-0.64 fixes this issue - adding another test for __res_mkquery in -lresolv if it didn't find res_mkquery in -lresolv. I've also dropped ipv6 support in 0.64 since: a. I couldn't make it work, and b. I don't see a patch against 0.64 anywhere... I'm also marking this ~amd64 (tested on amd64.g.o)
