The commits eac4324bfbe452f0292b48b2f1dc37b5052ec0be and cd8211527efbb9cad19db1c0d033da0749836e43 renamed the examples, but the targets were not updated. Hence, the builds are missing -lm. Signed-off-by: Sebastian Ramacher <sramacher@debian.org> Signed-off-by: James Almer <jamrial@gmail.com>
FFmpeg examples README ---------------------- Both following use cases rely on pkg-config and make, thus make sure that you have them installed and working on your system. Method 1: build the installed examples in a generic read/write user directory Copy to a read/write user directory and run: make -f Makefile.example It will link to the libraries on your system, assuming the PKG_CONFIG_PATH is correctly configured. Method 2: build the examples in-tree Assuming you are in the source FFmpeg checkout directory, you need to build FFmpeg (no need to make install in any prefix). Then just run "make examples". This will build the examples using the FFmpeg build system. You can clean those examples using "make examplesclean" If you want to try the dedicated Makefile examples (to emulate the first method), go into doc/examples and run a command such as PKG_CONFIG_PATH=pc-uninstalled make -f Makefile.example
