Dear List When I run "make menuconfig" on media_build the following errors occur: thomas@Intel64:~/Projects/dvb/media_build$ make menuconfig make -C /home/thomas/Projects/dvb/media_build/v4l menuconfig make[1]: Entering directory '/home/thomas/Projects/dvb/media_build/v4l' /lib/modules/4.10.0-33-generic/build/scripts/kconfig/mconf ./Kconfig ./Kconfig:5033: syntax error ./Kconfig:5032: unknown option "Choose" ./Kconfig:5035: syntax error ./Kconfig:5034:warning: ignoring unsupported character ',' ./Kconfig:5034: unknown option "In" ./Kconfig:5035: unknown option "that" ./Kconfig:5036: unknown option "this" ./Kconfig:5036:warning: ignoring unsupported character '<' ./Kconfig:5037:warning: ignoring unsupported character ':' ./Kconfig:5037: unknown option "file" Makefile:379: recipe for target 'menuconfig' failed make[1]: *** [menuconfig] Error 1 make[1]: Leaving directory '/home/thomas/Projects/dvb/media_build/v4l' Makefile:26: recipe for target 'menuconfig' failed make: *** [menuconfig] Error 2 thomas@Intel64:~/Projects/dvb/media_build$ The 2 spaces in the 2 lines after the "--help--" entry of "config RADIO_WL128X" are the problem (v4l/Kconfig). Anyway I don't know where these 2 spaces come from. In the media_tree, I don't see these two spaces. Can somebody look what is going wrong here, thanks. Thomas
