+Libav currently uses a custom build system, this text attempts to document
some of its obscure features and options.
-Options to make:
-make V=1 <target>
- Build target with verbosity 1, instead of 1, 2 can be used too
-make SAMPLES=<path to the fate samples> <target>
- specify the path to the fate samples at make time
+Makefile variables:
+V
+ Disable the default terse mode, the full command issued by make and its
+ output will be shown on the screen.
-Useful standard make commands:
-make -t <target>
- Touch all files that otherwise would be build, this is useful to reduce
- unneeded rebuilding when changing headers, but note you must force rebuilds
- of files that actually need it by hand then.
+DESTDIR
+ Destination directory for the install targets, useful to prepare packages
+ or install Libav in cross-environments.
-make -j<num>
- rebuild with multiple jobs at the same time. Faster on multi processor systems
+Makefile targets:
-make -k
- continue build in case of errors, this is useful for the regression tests
- sometimes but note it will still not run all reg tests.
+all
+ Default target, builds all the libraries and the executables.
+install
+ Install headers, libraries and programs.
-Targets to make:
-fate-list
- Will list all fate/regression test targets
+libavformat/output-example
+ Build the libavformat basic example.
-fate
- Run the fate test suite, note you must have installed it
+libavcodec/api-example
+ Build the libavcodec basic example.
+libswscale/swscale-test
+ Build the swscale self-test (useful also as example).
-Setting up local fate:
-use the following command to get the fate test samples
-rsync -aL rsync://rsync.mplayerhq.hu:/samples/fate-suite/ fate/fate-suite
-pass --samples=<path to the samples> to configure or pass the path with the
-SAMPLES variable to make
