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
