1 | FFmpeg currently uses a custom build system, this text attempts to document |
2 | some of its obscure features and options. | |
3 | ||
4 | Makefile variables: | |
5 | ||
6 | V | |
7 | Disable the default terse mode, the full command issued by make and its | |
8 | output will be shown on the screen. | |
9 | ||
10 | DESTDIR | |
11 | Destination directory for the install targets, useful to prepare packages | |
12 | or install FFmpeg in cross-environments. | |
13 | ||
14 | Makefile targets: | |
15 | ||
16 | all | |
17 | Default target, builds all the libraries and the executables. | |
18 | ||
19 | fate | |
20 | Run the fate test suite, note you must have installed it | |
21 | ||
22 | fate-list | |
23 | Will list all fate/regression test targets | |
24 | ||
25 | install | |
26 | Install headers, libraries and programs. | |
27 | ||
28 | examples | |
29 | Build all examples located in doc/examples. | |
30 | ||
31 | libavformat/output-example | |
32 | Build the libavformat basic example. | |
33 | ||
34 | libavcodec/api-example | |
35 | Build the libavcodec basic example. | |
36 | ||
37 | libswscale/swscale-test | |
38 | Build the swscale self-test (useful also as example). | |
39 | ||
40 | config | |
41 | Reconfigure the project with current configuration. | |
42 | ||
43 | ||
44 | Useful standard make commands: | |
45 | make -t <target> | |
46 | Touch all files that otherwise would be build, this is useful to reduce | |
47 | unneeded rebuilding when changing headers, but note you must force rebuilds | |
48 | of files that actually need it by hand then. | |
49 | ||
50 | make -j<num> | |
51 | rebuild with multiple jobs at the same time. Faster on multi processor systems | |
52 | ||
53 | make -k | |
54 | continue build in case of errors, this is useful for the regression tests | |
55 | sometimes but note it will still not run all reg tests. | |
