When compiling lirc for a new kernel configure uses the active linux kernel source directory instead. This can break lirc when there are differences between the the active kernel and the kernel lirc is build for. # emerge lirc <snipped> * Determining the location of the kernel source code * Found

I also stepped over this bug, and found the cause. In the ebuild econf gets --with-kerneldir=${ROOT}/usr/src/${KV_FULL} as parameter, but this directory does not exist (/usr/src/2.6.x vs /usr/src/linx-2.6.x). The attached patch corrects the ebuild by using KV_DIR.
Created attachment 80030 [details, diff] corrects kerneldir in ebuild lirc-0.8.0_pre3
thx, fixed in 0.8.0
