Description Martin von Gagern 2016-04-01 02:48:19 UTC
Re-merging umix fails for me:

x86_64-pc-linux-gnu-gcc -march=amdfam10 -O2 -ggdb -pipe -Wall -Wl,--as-needed -o
 umix umix_common.o umix.o mixer.o error.o ui.o ui_ncurses.o  -lncurses
/usr/lib/gcc/x86_64-pc-linux-gnu/5.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: u
i_ncurses.o: undefined reference to symbol 'cbreak'
/lib64/ error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:200: recipe for target 'umix' failed
make[2]: *** [umix] Error 1

Previous version has been around since 2009 on my system, and I guess I enabled the tinfo USE flag for ncurses after that.

Got bitten by this again during the world rebuild for the 17.0 profile migration. Guess I'll unmerge umix for now.
