Re: [cdt-dev] Adding new build option type: tree
|
Hi,
I have submitted a patch implementing the below mentioned proposal to support tree type in build options couple of months ago as https://bugs.eclipse.org/bugs/show_bug.cgi?id=365718
Is it possible that it is considered for inclusion in cdt.
We have been using it locally for the past couple of months with no problems so far.
Looking forward to your comments.
Best Regards,
Mohamed.
