Re: [cdt-dev] org.eclipse.cdt.core.dom.parser.c
|
Hi Andreas,
but the c source code is not valid. Copy and paste it in the Eclipse
CDT C Editor and you will see the error message.
I think that the non deprecated code you are using is propably more
tollerant against syntax errors.
Kind regards from Berlin ,Helko
Sincerely,
Helko Glathe
