When attempting to (re-)merge net-wireless/gr-scan, it fails. The error thrown by the link step is: /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /var/tmp/portage/net-wireless/gr-scan-20160211/temp/cc7CZwWj.o: undefined reference to symbol '_ZN7log4cpp8Appender29AppenderMapStorageInitializerD1Ev' This can be resolved by adding an explicit -llog4cpp to the LDLIBS variable in the Makefile.

Some time after the boost version was upgraded an "emerge -uDN world" tried to rebuild gr-scan, and I encountered the above error. I hand-tweaked the /var/tmp/portage/net-wireless/gr-scan-20160211/work/gr-scan-*/Makefile to append "-llog4cpp" to the end of LDLIBS and could then successfully complete the installation with "ebuild gr-scan-20160211.ebuild compile install qmerge".
Created attachment 706605 [details] build.log + emerge --info.txt Please attach full build.log and emerge --info when reporting build failures (even if doesn't seem needed), but I've reproduced so I'll just attach mine.
