To upgrade to a new revision of libjpeg-turbo, do the following:
|
|
|
|
* Check out libjpeg-turbo from SVN:
|
|
|
|
$ svn co https://libjpeg-turbo.svn.sourceforge.net/svnroot/libjpeg-turbo/trunk libjpeg-turbo
|
|
|
|
* In a clean clone of mozilla-central, run the following commands
|
|
|
|
$ rm -rf jpeg
|
|
$ svn export --ignore-externals /path/to/libjpeg-turbo jpeg
|
|
$ cd jpeg
|
|
|
|
* Now look through the new files and rm any which are npotb. When I upgraded
|
|
to libjpeg-turbo 1.1.0, the only files I kept which didn't match
|
|
|
|
*.c *.h *.asm *.inc
|
|
|
|
were README and README-turbo.
|
|
|
|
You can easily look for all non *.c, *.h, *.asm, and *.inc files by running
|
|
|
|
$ hg status -nu | grep -v '\(c\|h\|asm\|inc\)$'
|
|
|
|
Once you're comfortable that you're only deleting files you want to delete
|
|
(and you've hg add'ed the files you want to keep), you can nuke the remaining
|
|
files with
|
|
|
|
$ hg status -nu | grep -v '\(c\|h\|asm\|inc\)$' | xargs rm
|
|
|
|
A helpful command for finding the *.c files which aren't *currently* part of
|
|
the build is
|
|
|
|
diff <(ls *.c | sort) <(grep -o '\w*\.c' Makefile.in | sort)
|
|
|
|
of course, libjpeg-turbo might have added some new source files, so you'll
|
|
have to look though and figure out which of these files to keep.
|
|
|
|
* Restore files modified in the Mozilla repository.
|
|
|
|
$ hg revert --no-backup Makefile.in jconfig.h jmorecfg.h simd/Makefile.in \
|
|
simd/jsimdcfg.inc jchuff.c jdhuff.c jdhuff.h MOZCHANGES
|
|
|
|
* Update Makefile.in to build any new files.
|
|
|
|
* Finally, tell hg that we've added or removed some files:
|
|
|
|
$ hg addremove
|
|
|
|
|
|
== March 28, 2011 (initial commit, libjpeg-turbo v1.1.0 r469 2011-02-27) ==
|
|
|
|
* Modified jmorecfg.h to define UINT8, UINT16, INT16, and INT32 in terms of
|
|
prtypes to fix a build error on Windows.
|
|
|
|
* Defined INLINE as NS_ALWAYS_INLINE in jconfig.h.
|
|
|
|
* Removed the following files which are licensed under the wxWindows license:
|
|
|
|
bmp.c, bmp.h, jpegut.c, jpgtest.cxx, rrtimer.h, rrutil.h, turbojpeg.h,
|
|
turbojpegl.c
|
|
|
|
* Reverted the following files to what was previously in Mozilla's tree
|
|
(nominally libjpeg 6.2):
|
|
|
|
jchuff.c, jdhuff.c, jdhuff.h
|
|
|
|
since the versions of these files in libjpeg-turbo are also under the
|
|
wxWindows license. (It would have been nicer to revert them to the new
|
|
libjpeg-8b code, but that doesn't easily integrate with libjpeg-turbo.)
