It is a valid lirc configuration to have more than one driver at a time. With the old lirc ebuilds < 0.8.0-r1 you could do LIRC_OPTS="--with-driver=serial --with-driver=irman" now you should do: LIRC_DEVICES="serial irman" but it does not work. # emerge -av lirc These are the packages that would be merged, in order: Calculating dependencies... done!

That's by design, as the message tells you.
Created attachment 95002 [details, diff] patch to allow multiple driver builds with this patch you can use: LIRC_DEVICES="serial irman"
by removing the "die" on multiple drivers with the attached patch you can use multiple drivers eg: LIRC_DEVICES="serial irman"
We don't need a patch, we know how to enable it, but it's disabled *intentionally*.
Please explain why, or link to a reason why it is *intentionally* crippled. I and others need to support multiple types of devices. If there is an upstream bug where certian drivers do not work together, then that is not a gentoo problem. I really need an ebuild that works.
If there is a dependency, link to it. why LATER?
Sigh, just read the ebuild perhaps? It's written there.
What is in the ebuild: #ewarn "When selecting multiple devices for lirc to be supported," #ewarn "it can not be garanteed that the drivers play nice together." ewarn "lirc does at the moment support only one driver be compiled at a time." ewarn "Please reduce LIRC_DEVICES to one item." die "Multiple drivers selected for lirc." ... What i need and say that compiles and works is: LIRC_DEVICES="serial irman" There is no need to "die" in this case. The old way of LIRC_OPTS could do this..
I understand that this restriction seems like nonsense but at least it is not so easy possible to compile more than one driver that creates a kernel-modules. That statement can be proved by looking at that part of configure.in of lirc: if test "$driver" = "act200l"; then lirc_driver="lirc_dev lirc_sir" AC_DEFINE(LIRC_SIR_ACTISYS_ACT200L) fi if test "$driver" = "atiusb"; then lirc_driver="lirc_dev lirc_atiusb" lircd_conf="atiusb/lircd.conf.atiusb" fi ... repeated for all possibilities of --with-driver The problem here is that lirc_driver is overwritten for every driver that need a kernel module. -> Only for the last setting a Kernel-module is compiled. For your combination this will work as only --with-driver=serial will create a kernel-module. The possibilities are: a) Call configure for every --with-driver and copy the kernel-module. b) Change lirc_driver="xyz" to lirc_driver="${lirc_driver} xyz". Both possibilities will work for cases that no kernel-module is compiled two times with different options. But in every case compiling more than one driver should give a big fat warning about it.
Option A, I belive will break some configurations, where lircd will not run because it will say it was compliled with out support for driver xyx. I would vote for Option B. I am aware of the lirc limitation with kernel drivers, that is a lirc (upstream) limitation that I can live with. There are a few userspace lirc drivers that can be used at the same time. Having the gentoo ebuild support this would be nice. Yes, a big fat warning is needed.
Bug# 131306 https://bugs.gentoo.org/show_bug.cgi?id=131306 is where this was introduced. The old LIRC_OPTS, was in general more flexible than the new LIRC_DEVICES.. LIRC_DEVICES allowed to check dependencies on other needed libs. Would it perhaps be possible to use LIRC_DEVICES as default to solve dependencies, but have LIRC_OPTS override the configure opts if wanted?
Option B as described does not work so easily but requires huge changes to the configure-script. Perhaps Option A will work with first time calling configure with each option alone and for building lircd calling it with all arguments (or --with-driver=userspace). Requires a bit of investigation but then it should work.
Now allowing more than one driver (with warning) in lirc-0.8.0-r7.
