Building current Lirc ebuilds with the ftdi use flag brings in libftdi-0.20 via "ftdi? ( dev-embedded/libftdi:0 )" in the dependency check. During compile libftdi is not found as it is looking for version >= 1.0. The ebuild completes fine as it is an optional component. Reproducible: Always Steps to Reproduce: 1. Emerge Lirc with "ftdi" use flag 2. 3. Actual Results: No ftdi driver installs (/usr/lib64/lirc/plugins/ftdi.so missing) Expected Results: ftdi.so should be found in /usr/lib64/lirc/plugins/. ftdi driver should be an option in using lirc and its tools All 3 current ebuilds: lirc-0.10.1_p7.ebuild, lirc-0.10.1-r4.ebuild, and lirc-0.10.2.ebuild contain the incorrect dependency call. This issue is fixed by changing: - ftdi? ( dev-embedded/libftdi:0 ) + ftdi? ( dev-embedded/libftdi:1 ) in the ebuilds which brings in libftdi-1.5-r5. This version is correctly found during confirguration/compile and the driver builds and installs. Lirc and its tools now have this driver available to use. I tested and confirmed this change in my local overlay with a modified lirc-0.10.2.ebuild.
