DDD: Cannot convert string "-*-helvetica-medium-r-*-230-*-iso8859-*" to type FontStruct

I'm using DDD 3.3.12 to debug C/C++.The following is the OS infos:

RHEL6.0-2012-x86_64
Red Hat Enterprise Linux Workstation release 6.3

When I started DDD, it shows:

Warning: Cannot convert string "--helvetica-medium-r----230-----iso8859-" to type FontStruct (Annoyed? Try 'Edit->Preferences->General->Suppress X Warnings'!) Warning: Cannot convert string "--helvetica-medium-r----200-----iso8859-" to type FontStruct Warning: Cannot convert string "--helvetica-bold-r----230-----iso8859-" to type FontStruct Warning: Cannot convert string "--helvetica-medium-----230-----iso8859-" to type FontStruct Warning: Cannot convert string "--helvetica-bold-----230-----iso8859-" to type FontStruct Warning: Cannot convert string "--helvetica-bold-r----340-----iso8859-" to type FontStruct Warning: Cannot convert string "--symbol------230-----adobe-*" to type FontStruct

After I tried

'Edit->Preferences->General->Suppress X Warnings'!

Those warnings disappeared.

I changed the Font of DDD before. How can I avoid these warnings? Change the Font to default?

Solution

  • The warnings appears because the fonts selected by you are not supported by DDD yet.

    In your DDD, select

    Edit->Preferences->Fonts

    And, change all thing to the default like below:

    enter image description here

    Then，no warning will appear.
