I'm running Slack64-current but recently upgraded to GCC-5.1.0. I wanted to build the new versions of Firefox (38.0.1) and Thunderbird (31.7.0). Firefox went without a hitch but the Thunderbird build throws dozens of errors like the following:

error: converting to 'bool' from 'std::nullptr_t' requires direct-initialization [-fpermissive]
return nullptr;

Probably due to a tighter adherence to the C++ standard but, not being a programmer, I am at a loss as to how to fix this.

Does anyone know of a patch to address this? Thanks in advance.

Anyone???

Hi,

you need to replace every **reported** occurrence of "return nullptr;" with "return false;".

I just stumbled on the same problem when compiling Firefox 31 with gcc 5, and I am pretty convinced that this solution should be enough. However, I currently don't have time to do the manual work and try it out. In case you decide to do it (or you find an already finished patch), please let me know if it works

Regards,

Tom

Hello again,

can't sleep with unsolved problem in my head First, a little research:

* this problem was addressed almost a year ago, see https://bugzilla.mozilla.org/show_bug.cgi?id=1021171
* however, patch included in the bugreport won't work for version 31. There were some other changes before it, and the line numbers don't match
* so, I have created a "correct" one for Firefox/Thunderbird 31

Long story short, try this:

Let me know if it helps

Have a nice day,

Tom

Hello Tom and thank you for taking the time to not only reply but to create a patch. That is truly above and beyond. I had come across the "return false" solution in connection with other software while googling but wasn't sure if that applied here too. I have tried your patch but always get an error that it can't find the file in line 4 of the patch. Not to worry though. Now that you have pointed me to the fix I will carry on from here. Again, thank you very much.

Tom (yes, I am Tom too).

I've just about fixed all of the problem points. When I get it to build I'll post a patch.

OK, here is the patch. http://pastebin.ca/3006728

Hope it works for anyone interested.
