External Email - Use Caution        

Hello FreeSurfer community,

I believe I have installed both freetype and freetype-devel now.

I now get a new error, that is similar, but may have a slightly different solution:

Freeview:symbol lookup error: /usr/local/freesurfer/bin/../lib/qt/lib/libQt5Gui.so.5: undefined symbol: hb_font_funcs_set_font_h_extents_func

Does anyone have any advice regarding this error? 

1) FreeSurfer version: freesurfer-linux-centos7_x86_64-dev-20190416-14809f1
2) Platform: Red Hat Enterprise Linux 7

Thank you for your help!

When I look within /usr/lib64 (using ls *libfreetype*) , I see:
lib64/libfreetype.so.6  lib64/libfreetype.so.6.10.0

When I type:
strings /usr/lib64/libfreetype.so.6 | grep -i ft_get_font_format
I do not get any output.

When I type:
sudo yum install freetype.x86_64 freetype-devel.x86_64
the first package installs, but I get the following error message for the second package:
No package freetype-devel.x86_64 available.
Error: Nothing to do

I have seen these types of errors on this computer many times when I try to install or use different programs, so I understand if it is not actually a FreeSurfer problem. If anyone has any advice, I would love to hear it. I'll continue to try to solve it on my own as well.

​Hello Kelly,

Do you have libfreetype installed on your system (which defines that symbol)?

$ strings /usr/lib64/libfreetype.so.6 | grep -i ft_get_font_format
FT_Get_Font_Format

If not, you can install it with,

$ sudo yum install freetype.x86_64 freetype-devel.x86_64

- R.
