Here is supposed that current compiled file do not contains other (real) errors.

I am using CodeBlocks, built from sources,  revision 2977, with the exception that it is built against non-monolithic wxWidgets (2.6.3)  library, under WindowsXP SP2.

takeshimiya:
Yes it's common that the regex fails when parsing template warning/errors, and linker errors almost never are parsed; however it is because ld usually doesn't outputs an "Error" string.

I wonder, there is any switch for ld to make it output parseable errors? Maybe -undefined?

kkez:
You can add a regex before all the other ones (you can do it since it's more specific) to catch the "initiated from here" message. Try my patch:

Indrekis:
Thank you for your reply! but,
The patch gives no visible effect for me  :(

mandrav:
For those changes to take effect you have to "Reset" your compiler settings.
