LittleCMS 1.19 - Installation guide
|
||
|
|
|
||
|
|
|
||
|
|
Configuration
|
||
|
|
*************
|
||
|
|
|
||
|
|
All configuration is done by the configure script on linux.
|
||
|
|
|
||
|
|
If you want to fine-tune the library, this can be done by
|
||
|
|
editing lcms.h
|
||
|
|
|
||
|
|
Normally, there is no need to touch anything. Only make sure
|
||
|
|
to set properly the NON_WINDOWS toggle if you are using the
|
||
|
|
engine in non MS-Windows environments (set by default), and
|
||
|
|
USE_BIG_ENDIAN if your machine does use this convention.
|
||
|
|
Remaining toggles does control optimization degree. If your
|
||
|
|
compiler does support the new __int64 or "long long" type,
|
||
|
|
(gcc does) you can gain speed by defining the USE_INT64 toggle.
|
||
|
|
There is an experimetal multi-threading mode which may be
|
||
|
|
activated by uncommenting USE_PTHREADS toggle. However, this
|
||
|
|
is only for completness sake as the current code should be
|
||
|
|
thread-safe on all but a very small fraction of time. So, use
|
||
|
|
the toggle only if you make _extensive_ use of threads on
|
||
|
|
multiprocessor architectures.

Installation
|
||
|
|
*************
|
||
|
|
|
||
|
|
Linux/Mac/unices
|
||
|
|
================
|
||
|
|
|
||
|
|
Unpack & untar the tarball (you already did!) and then type
|
||
|
|
|
||
|
|
./configure
|
||
|
|
make
|
||
|
|
make check
|
||
|
|
|
||
|
|
This latter will run the testbed program as well. If you want to
|
||
|
|
install the package, type
|
||
|
|
|
||
|
|
make install
|
||
|
|
|
||
|
|
This does copy lcms.h and icc34.h into /usr/local/include and
|
||
|
|
liblcms.a into /usr/local/lib
|
||
|
|
|
||
|
|
There is also a simple, old version compatible script. If you
|
||
|
|
experience any problem with automake try this one:
|
||
|
|
|
||
|
|
make -f makefile.simple
|
||
|
|
|
||
|
|
this is just to keep compatibility with old versions.
|
||
|
|
|
||
|
|
|
||
|
|
For cleaning object and binaries files type 'make clean'
|
||
|
|
|
||
|
|
There are these targets on Makefile:
|
||
|
|
|
||
|
|
install: Does install package
|
||
|
|
check: builds and executes testbed program
|
||
|
|
clean: Deletes object & binary files
|
||
|
|
|
||
|
|
|
||
|
|
NOTE: The package doesn't build with srcdir!=builddir
|
||
|
|
That is because a pre-generated icc34.h located at
|
||
|
|
'include' folder. This is needed for windows installs.
|
||
|
|
So, if you plan to build the package using any builddir
|
||
|
|
different from srcdir, please delete this file.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Windows
|
||
|
|
=======
|
||
|
|
|
||
|
|
There are projects for most popular environments in the
|
||
|
|
'Projects' folder. Just locate which one you want to use.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Tifficc & jpegicc
|
||
|
|
=================
|
||
|
|
automake will try to detect whatever you have libtiff and
|
||
|
|
libjpeg and if found build these additional utilities.
|
||
|
|
|
||
|
|
Only if you are using makefile.simple:
|
||
|
|
|
||
|
|
If you have libz, libtiff and libjpeg installed, there are
|
||
|
|
some additional utilities for converting images using icc profiles.
|
||
|
|
Since lcms doesn't require these libraries to work, and in order
|
||
|
|
to minimize the dependency carrousel, these utilities are not builded
|
||
|
|
by default. If you want to build them, type 'make utils'. I will
|
||
|
|
recommend to give a try if you are interested in color management.
|
||
|
|
tifficc can do wonderful things like converting CMYK separations
|
||
|
|
to displayable files and other interesting stuff. Run the executable
|
||
|
|
without parameters to see how it works.
|
||
|
|
|
||
|
|
|
||
|
|
Removing //-C++ style comments
|
||
|
|
==============================
|
||
|
|
|
||
|
|
There is a utility on root called 'filter.c' If your compiler
|
||
|
|
doesn't support C++-style comments, apply this filter to all
|
||
|
|
source & headers. Probably you would need to make your own
|
||
|
|
compilation script too. I will love! to know any exotic environment
|
||
|
|
using lcms, so please me know if it worked.
|
||
