emerge -pv media-libs/alsa-lib
输出
[ebuild N ] media-libs/alsa-lib-1.0.21a USE="-alisp -debug -doc -python" ALSA_PCM_PLUGINS="-adpcm -alaw -asym -copy -dmix -dshare -dsnoop -empty -extplug -file -hooks -iec958 -ioplug -ladspa -lfloat -linear -meter -mmap_emul -mulaw -multi -null -plug -rate -route -share -shm -softvol"
但是
emerge --info
输出
ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol"
执行
emerge media-libs/alsa-lib
后出现 * Messages for package media-libs/alsa-lib-1.0.21a:
* You haven't selected _any_ PCM plugins. Either you set it to something like the default
* (which is being set in the profile UNLESS you unset them) or alsa based applications
* are going to *misbehave* ! 这是为什么呢?
我用的profile是
/usr/portage/profiles/default/linux/amd64/10.0/no-multilib
并且在/etc/make.conf中不包含对ALSA_PCM_PLUGINS的设置 |
