enable FreeType in local GB compile

[Hoover, David (NIH/CIT) [E]]

Hi all,

The latest versions of the Genome Browser now have a new feature, FreeType. We have the FreeType package locally installed, but yet I can't seem to have it enabled during the build. Is there some other trick to have it locate the FreeType libraries on the host?

Dear David,

Thanks for reaching out to the Genome Browser support team regarding freeType fonts. One of our engineers suggests the following solution:

Install FreeType and add the following line to your inc/common.mk file:

HG_INC+=-I/usr/include/freetype2 -DUSE_FREETYPE

Alternately, there is a way to turn off the font options via hg.conf with “freeType=off” as a setting.

Please note that we now distribute the fonts in the htdocs/urw-fonts directory, available here:

rsync rsync://hgdownload.soe.ucsc.edu/htdocs/urw-fonts/

I hope this works for your mirror! For further communication, please reply-all to genome...@soe.ucsc.edu. Those emails are archived in a public forum. For private questions, you may send emails instead to genom...@soe.ucsc.edu.

All the best,

Dear David,

Thank you for sharing the experiences with FreeType errors when compiling.

We have updated our src/inc/common.mk file to have improved checks for freetype-config existence and you can get the lastest version here:
https://genome-source.gi.ucsc.edu/gitlist/kent.git/blob/master/src/inc/common.mk

Or see the specific changes here:
https://genome-source.gi.ucsc.edu/gitlist/kent.git/commit/8fff967390b185e152a6faf2a7335e5db23a9ff7

Thank you again for sharing these experiences and helping us improve the UCSC Genome Browser for mirror administrators!

All the best,

Dear UCSC team,

I git pulled the latest code and now have a linking problem with ixIxx:

kent/src/index/ixIxx (master)$ cc -O -g -o /home/mhiller/bin/x86_64/ixIxx ixIxx.o ../../lib/x86_64/jkweb.a -L/usr/lib64/ -lmariadb -lstdc++ -lrt -lfreetype -lpthread -lssl -lcrypto ../../htslib/libhts.a -L/usr/lib64 -lpng16 -lm -lz -liconv -lm

ixIxx.o:/genome/src/kent/src/index/ixIxx/ixIxx.c:84: first defined here
collect2: error: ld returned 1 exit status

The problem is that several functions that were originally only included in ixIxx.c are now also added to ../../lib/trix.c
which makes the linker complain.

grep initCharTables ../../* -R
../../hg/oneShot/testIndex/testIndex.c:void initCharTables()
../../hg/oneShot/testIndex/testIndex.c:initCharTables();
../../inc/trix.h:void initCharTables();
../../index/ixIxx/ixIxx.c:void initCharTables()
../../index/ixIxx/ixIxx.c:initCharTables();
Binary file ../../index/ixIxx/ixIxx.o matches
../../lib/trix.c:void initCharTables()
../../lib/trix.c:initCharTables();

git log shows that these functions were added 3 weeks ago with commit af3a143571.


Thanks a lot
- Michael
