================= Compile LibRaw with RawSpeed support ========================
|
|
|
|
0) RawSpeed version:
|
|
LibRaw supports 'master' version of RawSpeed library: https://github.com/darktable-org/rawspeed/tree/master
|
|
|
|
Although this version is really outdated, newer versions does not looks stable enough for production
|
|
use (for example, this critical issue not fixed for 10+ months: https://github.com/darktable-org/rawspeed/issues/100 )
|
|
|
|
1) Prerequisites
|
|
|
|
To build RawSpeed you need libxml2, iconv, and JPEG library installed on your
|
|
system.
|
|
|
|
2) Build RawSpeed:
|
|
|
|
-- consult http://rawstudio.org/blog/?p=800 for details
|
|
|
|
-- Win32: you need POSIX Threads for Win32 installed on your system
|
|
(http://sources.redhat.com/pthreads-win32/)
|
|
|
|
-- use provided RawSpeed/rawspeed.samsung-decoder.patch to fix
|
|
old Samsung decoder bug
|
|
|
|
-- you may use qmake .pro files supplied in LibRaw distribution
|
|
(RawSpeed/rawspeed.qmake-pro-files.patch)
|
|
Adjust path to libraries/includes according to your setup.
|
|
|
|
-- Win32: you need to add __declspec(..) to external C++ classes.
|
|
Use patch provided with LibRaw (RawSpeed/rawspeed.win32-dll.patch)
|
|
|
|
-- Unix: you need to define rawspeed_get_number_of_processor_cores() call
|
|
For most unix systems (Linux, MacOS X 10.4+, FreeBSD) patch provided
|
|
with LibRaw (RawSpeed/rawspeed.cpucount-unix.patch) should work.
|
|
|
|
3) Build LibRaw with RawSpeed support:
|
|
|
|
Win32:
|
|
--Uncomment CFLAGS_RAWSPEED and LDFLAGS_RAWSPEED lines in
|
|
Makefile.msvc. Adjust paths to libraries/includes if needed.
|
|
-- run nmake -f Makefile.msvc
|
|
|
|
Unix/MacOS:
|
|
-- Uncomment CFLAGS/LDADD lines in RawSpeed section in Makefile.dist
|
|
-- Uncomment RAWSPEED_DATA line if you wish to rebuild
|
|
internal copy of RawSpeed's cameras.xml
|
|
-- run make -f Makefile.dist
|
|
|
|
Compile options:
|
|
-- You may specify -DNOSONY_RAWSPEED define if you do not want to use
|
|
RawSpeed's Sony formats decoder (because result of this decoder is
|
|
different from LibRaw's built-in decoder)
|
|
|
|
4) Build/run your Apps with LibRaw+RawSpeed
|
|
|
|
-- Build as usual, no changes required in your apps unless you
|
|
access LibRaw::imgdata.rawdata.raw_image[] directly
|
|
|
|
-- you may turn off RawSpeed support on runtime by setting
|
|
imgdata.params.use_rawspeed to 0.
|
|
|
|
-- You'll need all shared libraries you linked to at runtime (libxml2,
|
|
iconv, LibJPEG, and posix threads on Win32).
