Bugzilla Bug 230802

libecwj2 is apparently required to support the gdal configuration for Oracle,
however, it has two headers in common with lcms.  The diffs are enormous...

 * Detected file collision(s):
 * 
 *      /usr/include/lcms.h
 *      /usr/include/icc34.h
 * 
 * Searching all installed packages for file collisions...
 * 
 * Press Ctrl-C to Stop
 * 
 * media-libs/lcms-1.17
 *      /usr/include/icc34.h
 *      /usr/include/lcms.h

Apparently in Source/C/ there's a number of included libraries. At least lcms
libjpeg and tinyxml should be external dependencies. Didn't look deeper into
the code.

Any decision on this?

Hello nerdboy,
this ebuild have to be reviewed to be able to use the dependencies packages
during the installation process.

I have to investigate in this way.

In the interim, I wrote a patch that simply eliminates lcms support in
libecwj2. We've been using the patched libecwj2 for a few months now and
haven't noticed any odd behavior, but admittedly we don't use libecwj2 directly
but only as a GDAL dependency for JPEG2000 support. Perhaps a 'nolcms' use flag
could be used to enable the patch for people who don't need lcms support in
libecwj2?

libecwj2-3.3 nolcms patch

*** This bug has been marked as a duplicate of bug 202594 ***

Can somebody post an updated ebuild to apply the proposed patch ?

libecwj2-3.3-r1 ebuild

Here's the ebuild we're currently using to apply our nolcms patch.

This ebuild depends on automake-1.7 :

On a new PC (Intel Core i7, Gentoo 64 bits), I have a problem during the
installation, using the new ebuild :

I solved it by re-enabling the line :
   mkdir -p "${D}usr/include" # hack to enable install of include files
that Brian had commented out.
