Until now (31.03.2011) only one pkg-config file exists: openjpeg1.pc .

But OpenJPEG-1.4.0 may create three libraries: libopenjpeg.* libopenjpeg_JPWL.* libopenjp3dvm.*

So two pkg-config files are missing.

i think that there are still 2 missing .pc files, but it's for jpwl and jpip.

Btw, usually, in FOSS, they are named with a '-' and in lower case, like:

openjpeg-jpwl.pc

I'll send a patch

Vincent Torri

for 1.6 release

OpenJPEG 2.0 does not include any pkg-config files at all. This makes it unnecessarily difficult for projects that do not use cmake to build against OpenJPEG.

sorry, this is on my plate to help implement... will try to make some progress this week.

This issue is causing me pain too. I maintain an image processing library which depends on openslide, which in turn depends on openjpeg. With no pkgconfig it's much harder than it should be for me to make Windows and OS X binaries.

I found this mail with a possible pkg-config.pc.cmake.in file:

https://groups.google.com/forum/?fromgroups=#!topic/openjpeg/arDqgbryCsg

I don't know if that helps.

Hello,

The lack of pkg-config files prevents FFmpeg (or any softwares depending on openjpeg) from using openjpeg 2.0. It would be really great if you can fix this issue.

Thanks in advance.

Sorry for the delay... I'll try to make this a priority to work on soon

There is a 'libopenjp2.pc' since looooong.

What is missing is a PC file for JPWL.

But is that necessary? When I know where the JP2 file is installed, then I know where the JPWL file is installed.

It should be possible to run, for example, "pkg-config --libs openjpwl" to obtain the complete set of linker options needed to link with the library. Yes, it would be possible to run "pkg-config --variable=libdir libopenjp2" and use the output to construct the linker command line, but that's not how pkg-config is supposed to work.

As the condition 'if(UNIX)' is not removed in the main CMakeLists.txt, the following changes in the main CMakeLists.txt are:

Are the lines

necessary for JPIP?

The change in CMakeLists.txt is wrong. I added an earlier version of the diff file. The correct diff file is:

working on it for real now. Thanks for the good start.

I suppose there is probably interest to backport this to branches/openjpeg-2.0 too?

Backported to branches/openjpeg-2.0 with https://code.google.com/p/openjpeg/source/detail?r=2349
