FFmpeg currently uses a custom build system, this text attempts to document
|
||
some of its obscure features and options.
|
||
|
||
Makefile variables:
|
||
|
||
V
|
||
Disable the default terse mode, the full command issued by make and its
|
||
output will be shown on the screen.
|
||
|
||
DBG
|
||
Preprocess x86 external assembler files to a .dbg.asm file in the object
|
||
directory, which then gets compiled. Helps in developing those assembler
|
||
files.
|
||
|
||
DESTDIR
|
||
Destination directory for the install targets, useful to prepare packages
|
||
or install FFmpeg in cross-environments.
|
||
|
||
GEN
|
||
Set to ‘1’ to generate the missing or mismatched references.
|
||
|
||
Makefile targets:
|
||
|
||
all
|
||
Default target, builds all the libraries and the executables.
|
||
|
||
fate
|
||
Run the fate test suite, note that you must have installed it.
|
||
|
||
fate-list
|
||
List all fate/regression test targets.
|
||
|
||
install
|
||
Install headers, libraries and programs.
|
||
|
||
examples
|
||
Build all examples located in doc/examples.
|
||
|
||
checkheaders
|
||
Check headers dependencies.
|
||
|
||
alltools
|
||
Build all tools in tools directory.
|
||
|
||
config
|
||
Reconfigure the project with the current configuration.
|
||
|
||
tools/target_dec_<decoder>_fuzzer
|
||
Build fuzzer to fuzz the specified decoder.
|
||
|
||
tools/target_bsf_<filter>_fuzzer
|
||
Build fuzzer to fuzz the specified bitstream filter.
|
||
|
||
Useful standard make commands:
|
||
make -t <target>
|
||
Touch all files that otherwise would be built, this is useful to reduce
|
||
unneeded rebuilding when changing headers, but note that you must force rebuilds
|
||
of files that actually need it by hand then.
|
||
|
||
make -j<num>
|
||
Rebuild with multiple jobs at the same time. Faster on multi processor systems.
|
||
|
||
make -k
|
||
Continue build in case of errors, this is useful for the regression tests
|
||
sometimes but note that it will still not run all reg tests.
