Re: [Nano-devel] [PATCH] index/RGB colors and italic/reverse/underline attributes

[David Ramsey]

I've tried applying this patchset in order to test it, but it fails at
the linking stage on my system:

gcc  -g3 -Wall   -o nano browser.o chars.o color.o cut.o files.o
global.o help.o history.o move.o nano.o prompt.o rcfile.o search.o
text.o utils.o winio.o ../lib/libgnu.a   -lz -lmagic  -lncursesw
color.o: In function `init_lut':

/home/dramsey/software/Slackware/nano/git/nano-colors/src/color.c:493:

collect2: error: ld returned 1 exit status

According to the manual page, the round() function is in libm.  If I
manually add "-lm" to LDFLAGS when trying to build (since I'm not sure
how to adjust Makefile.am to add it there), linking succeeds.
