Yann Collet 456db0c377 make install only rebuild binaries if they don't exist 
Now `make` followed by `make install` doesn't rebuild binaries

also : only generated target directories if they don't already exist

and when HASH is not found
 2020-10-23 10:14:04 -07:00
Yann Collet d3f1a9b5bd fix partial-build test 
sometimes, the scope difference is solely determined by the list of source files,
not by the flags.
 2020-10-22 21:36:09 -07:00
Yann Collet a912ef0952 can integrate later dynamic flags changes 
for example `libzstd-mt` is `differentiated from `libzstd`

same rules as lib/libzstd
can also be controlled via HASH and BUILD_DIR

Yann Collet 0f8ee5c51e Merge branch 'dev' into libzstd_autoconf 2020-10-21 22:36:09 -07:00
Yann Collet d0436b2a45 automatically detect configuration changes 
Makefile now automatically detects modifications of compilation flags,
and produce object files in directories dedicated to this compilation flags.
This makes it possible, for example, to compile libzstd with different DEBUGLEVEL.
Object files sharing the same configration will be generated into their dedicated directories.

Also : new compilation variables
- DEBUGLEVEL : select the debug level (assert & traces) inserted during compilation (default == 0 == release)
- HASH : select a hash function to differentiate configuration (default == md5sum)
- BUILD_DIR : skip the hash stage, store object files into manually specified directory
 2020-10-21 19:22:45 -07:00
Yann Collet 8a453a34c5 automatic %.h header dependency tracking 
also : BUILD_DIR can be manually specified

Yann ColletandGitHub 2224ec33ed Merge pull request #2367 from facebook/progressive_build

Yann Collet e8eb2939fe store %.o object files into obj/ 
both static and dynamic libraries have their own object directory
 2020-10-21 03:44:38 -07:00
Yann Collet 3e519be965 minor cleaning 2020-10-21 03:22:27 -07:00
Yann Collet 911dbdbb4b build libzstd.so from object files 
%.o object files generated for dynamic library
must be different from those generated for static library.

Due to this difference, %.o were so far only generated for the static library.
The dynamic library was rebuilt from %.c source.

This meant that, for every minor change, the entire dynamic library had to be rebuilt.

This is fixed in this PR :
only the modified %.c source get rebuilt.
