From 947b57da19e6308fed7f66ba827aa9a46c8c7d73 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 14 Oct 2012 08:18:21 +0000 Subject: [PATCH] libv4l: decode-tm6000 requires libv4l2util The decode-tm6000 utility cannot build without the libv4l2util. If this library is not available, the build breaks with: decode_tm6000.o: In function `read_stream': decode_tm6000.c:(.text+0x220): undefined reference to `v4l2_rcvbuf' decode_tm6000.o: In function `main': decode_tm6000.c:(.text+0x37c): undefined reference to `v4l2_open' decode_tm6000.c:(.text+0x3cc): undefined reference to `v4l2_gettryset_fmt_cap' decode_tm6000.c:(.text+0x424): undefined reference to `v4l2_getset_freq' decode_tm6000.c:(.text+0x47c): undefined reference to `v4l2_mmap_bufs' decode_tm6000.c:(.text+0x4a0): undefined reference to `v4l2_start_streaming' See http://autobuild.buildroot.org/results/207ed74d5e816309ef0dc82ecc8112b51788fdf6/build-end.log We fix this by adding util/libv4l2util to the list of directories to build when decode-tm6000 is enabled. The only other user of libv4l2util is another utility called qv4l2, for which Buildroot has no Config.in option, so we only handle the case of decode-tm6000 at the moment.
