When building statically zbar, build fails on: configure: error: unable to find libv4l.so The following errors are raised in config.log: configure:19371: /home/buildroot/buildroot-test/instance-0/output/host/bin/arm-linux-gcc -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -O2 -g2 -static -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -static conftest.c -lv4l2 -lpthread >&5 /home/buildroot/buildroot-test/instance-0/output/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libv4l2.a(libv4l2_la-libv4l2.o): In function `v4l2_set_src_and_dest_format': /home/buildroot/buildroot-test/instance-0/output/build/libv4l-1.16.2/lib/libv4l2/libv4l2.c:952: undefined reference to `v4lconvert_supported_dst_format' To fix this error, bump to version 57d601e82089f2f31de9e1683c3834f237421f5d to replace AC_CHECK_LIB by PKG_CHECK_MODULES to find the correct library (-lv4lconvert but also -ljpeg, ...)

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
