Description

The CORE Generator software (run in debug mode; coregen -ddd) fails to generate some IP cores, and warning messages similar to the following appear in the console: 

EBUG[generation] - Full EJava error output: 
WARNING: Default charset MS950 not supported, using ISO-8859-1 instead 
DEBUG[generation] -  
DEBUG[Generation] - Error: Failed to generate file: core_v 
ERROR:sim - Error: Failed to generate file: core_v 
Error found during generation. 
DEBUG[taskexecutor] - Command: generate finished" 

The problem seems to be related to the character set and has been seen when using MS950 and GBK. It does not occur on an OS with the language set to English.

Solution

To work around this problem, add the environment variable JAVA_TOOL_OPTIONS to the following value: 

JAVA_TOOL_OPTIONS = "-Dfile.encoding=UTF8"
