Created attachment 5864 [details] .config of buildroot I tried to built modular X.org server and built stopped while configuring xdriver_xf86-input-evdev with following message: --- checking for XORG... no configure: error: Package requirements (xorg-server >= 1.10 xproto inputproto) were not met: Package xorg-server was not found in the pkg-config search path. Perhaps you should add the directory containing `xorg-server.pc' to the PKG_CONFIG_PATH environment variable No package 'xorg-server' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables XORG_CFLAGS and XORG_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. --- If I deselect xdriver_xf86-input-evdev in menuconfig the next selected xdriver (in my case xdriver_xf86-input-keyboard) failed at the same step. I can confirm this for xdriver_xf86-input-evdev, xdriver_xf86-input-keyboard, xdriver_xf86-input-mouse and xdriver_xf86-input-tslib. Attached my buildroot config.
I can not reproduce the bug: checking whether make supports nested variables... (cached) yes checking for XORG... yes checking for UDEV... yes checking for XI22... yes checking for MTDEV... no checking that generated files are newer than configure... done configure: creating ./config.status config.status: creating Makefile config.status: creating src/Makefile config.status: creating man/Makefile config.status: creating include/Makefile config.status: creating xorg-evdev.pc config.status: creating config.h config.status: executing depfiles commands config.status: executing libtool commands configure: WARNING: unrecognized options: --disable-gtk-doc, --disable-gtk-doc-html, --disable-doc, --disable-docs, --disable-documentation, --with-xmlto, --with-fop, --enable-ipv6, --disable-debug >>> xdriver_xf86-input-evdev 2.8.2 Building
I also tested the configuration, on Buildroot 2014.11, and it builds fine. I believe your problem was probably due to the fact that you didn't do a full rebuild ('make clean all') after doing some configuration changes. See http://buildroot.org/downloads/manual/manual.html#full-rebuild for more details. I'm closing the bug. Do not hesitate to reopen if you're still experiencing the issue after a 'make clean all'.
