Trivial issue. I have a script to rebuild asterisk with the following line: menuselect/menuselect --disable MENUSELECT_MOH --disable CORE-SOUNDS-EN-GSM --enable CORE-SOUNDS-EN-WAV --enable app_macro --enable codec_opus --enable chan_phone --enable chan_sip --enable chan_sip --enable chan_sip --enable chan_oss --enable chan_phone --enable format_ogg_speex --enable res_corosync --enable format_vox --disable-category ME NUSELECT_AGIS --disable-category MENUSELECT_CORE_SOUNDS --disable-category MENUSELECT_MOH Everything compiles as desired except res_corosync. I then can run: make menuselect ...and manually select res_corosync, and the module compiles without incident. Does the order of enables matter?
