Re: [icu-support] Building and Installing libiculx and icu-lx.pc

[Steven R. L. <sr...@gm...>]

Hi!

Just a note that since I wrote those instructions, I don’t personally have funding for paragraph layout (or ICU). There was a ticket (which I can’t find!) to improve this build process. What should happen is that libiculx should be split out to a separate library, outside of the main ICU build! Help is wanted here if you or some other reader would like to contribute.

Now, on to your issue, my replies inline:

Did the configure at step 5 work properly? Did "pkg-config --modversion icu-le-hb” return a version number?

I see the link to icu-le-hb is incorrect, it should go to <https://github.com/harfbuzz/icu-le-hb> not to harfbuzz.org <http://harfbuzz.org/>.  
**Would someone from ICU be able to fix this link under 3. 	• Build and install the icu-le-hb library ** ?

It sounds like icu-le-hb is not installed properly.

see above

This discussion confirms that icu-le-hb is not installed properly.  Because this is NOT an ICU issue, let’s continue the discussion over at that discussion.
