Rstudio on redhat 6 does not load fonts anymore

[nordstroem]

I have rstudio-0.98.1103 Desktop installed on Red Hat Enterprise Linux Server release 6.7 (Santiago). When I start rstudio on the redhat server (I am using X11 forwarding to render on my local windows box) then I see the rstudio gui but all characters are displayed as black squares.

I was interested in which shared object libraries were loaded by rstudio so I looked up the PID and found the following in /prod/PID/maps

When I compare the libgstreamer version to the objdump of libQtWebKit.so.4.9.0 (inside of ~/rstudio/bin/) then I see

Dynamic Section:
NEEDED libXrender.so.1
NEEDED libQtGui.so.4
NEEDED libQtNetwork.so.4
NEEDED libQtCore.so.4
NEEDED libpthread.so.0
NEEDED libgio-2.0.so.0

This is slightly different from what is loaded by rstudio (see above the loaded .so files have a 0.25.0 appended. Is that a problem?

Here are some more details that might help:

• R: version 3.5.1 (x86_64)

Thanks for the help!

Any chance you can try updating to a newer release of RStudio? v0.98 is quite old at this point. You might try the v1.2 preview release.

[nordstroem]

is that compatible with redhat 6? On the rstudio page it says redhat 7+

Thanks

You can update your version to at least RStudio Server 1.2.1153. It requires Redhat/CentOS 6+ (64-bit) version at least. follow the below link for direct download.
