Hi

I get a warning about the implicit declaration of exp10 for amixer (not alsamixer). The same issue was reported at beginning of the year for alsamixer [0,1] and solved by adding -D_GNU_SOURCE to the CFLAGS. (In fact both alsamixer and amixer use the same file alsamixer/volume_mapping.c.) I suggest adding the same CFLAG also to the amixer Makefile.am.

Cheers Milton

Get rid of a warning about implicit declarition of exp10, which is behind _GNU_SOURCE as a non-standard feature. The same problem was fixed for alsamixer in commit 116488e5f2f1b897084bd151381ee254e1cc177d. --- amixer/Makefile.am | 1 + 1 file changed, 1 insertion(+)
