Bugzilla Bug 130374

(Side note: This package uses 'smp' as the use flag for enabling threading
rather than 'threads')


charm-5.9/net-linux/tmp/MsgPacker.h, line 86:
        MsgPacker::MsgPacker(CkQ<char *> &msgq, int n_msgs);

This file is generated from: src/ck-com/MsgPacker.h

Removing "MsgPacker::" from this line allows this build to compile using GCC
4.1.0 and GCC 3.4.5.





Tail end of the failing emerge:

Hi Brady,

Thank you very much for your note! I just checked the latest CVS
snapshot, and the change you indicated is already in cvs head. 
I'll check if I notice any additional gcc-4.1 specific fixes and merge
them into a cumulative patch if necessary.

Best,
Markus

Created an attachment (id=84987) [details]
patch to fix compile problems with gcc4

Could you please give the attached patch a spin; it works for me.
It pretty much consists of your fix plus a few missing virtual destructors
that could cause problems down the road.

Thanks,
Markus

Worked great! =)

I just added an epatch line and it flied right through =)

Thanks for the help with this! =)

Hi Brady,

Thank you very much for testing and the fix is
in cvs.

best,
Markus
