I get the following error > logs... Is this broken? Well... no, it is not really broken, but the build system for v4l2-apps needs serious improvements. There are some know issues on it: - It doesn't check/warn if you don't have all the dependencies (qv4l2 and v4l2-sysfs-path require some development libraries that aren't available per default when gcc is installed - I think the other files there are ok); - make only works fine when calling on certain directories (it used to work fine if you call it from /v4l2-apps/*) - but, since some patch, it now requires that you call make from /v4l2-apps, in order to create v4l2-apps/include. After having it created, make can be called from a /v4l2-apps subdir; - for some places (libv4l - maybe there are other places?), you need to have the latest headers installed, as it doesn't use the one at the tree. - qv4l2 only compiles with qt3. Patches are welcome to fix those issues and improve the v4l2-apps building system. > make[3]: Entering directory `/local/mkaricheri/davinci_git/video_timing/new_v4l2-dvb/v4l-dvb-aba823ecaea6/v4l2-apps/libv4l' > make -C libv4lconvert V4L2_LIB_VERSION=0.6.2-test all > make[4]: Entering directory `/local/mkaricheri/davinci_git/video_timing/new_v4l2-dvb/v4l-dvb-aba823ecaea6/v4l2-apps/libv4l/libv4lconvert' > cc -Wp,-MMD,"libv4lconvert.d",-MQ,"libv4lconvert.o",-MP -c -I../include -I../../../include -fvisibility=hidden -fPIC -DLIBDIR=\"/usr/local/lib\" -DLIBSUBDIR=\"libv4l\" -g -O1 -Wall -Wno-unused -Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes -o libv4lconvert.o libv4lconvert.c > In file included from libv4lconvert.c:25: > ../include/libv4lconvert.h:100: warning: "struct v4l2_frmsizeenum" declared inside parameter list > ../include/libv4lconvert.h:100: warning: its scope is only this definition or declaration, which is probably not what you want > ../include/libv4lconvert.h:105: warning: "struct v4l2_frmivalenum" declared inside parameter list In this specific case, it is trying to compile against /usr/include/linux/videodev2.h, instead of using the in-tree header file.
