wxWidgets26 does not build on Leopard - conflicting function declarations

[simon@…]

FSVolumeMount has conflicting declarations, see below (complete build log attached):

../src/mac/carbon/morefilex/MoreFilesX.h: At global scope:
../src/mac/carbon/morefilex/MoreFilesX.h:1488: error: declaration of C function 'OSErr FSVolumeMount(const void*, FSVolumeRefNum*)' conflic
ts with
/System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Headers/Files.h:7299: error: previous declaration 'OSStat
us FSVolumeMount(UInt8*, FSVolumeRefNum*)' here

I don't think putting bare usernames in the cc field works.

AFAIK, you need wxWidgets 2.8 for Leopard support...

[simon@…]

Thanks. I tripped over this as a dependency of the bittorrent port. Would it make sense to apply the changes in Portfile.diff to this port?

Cc reporter of dup #16278.

[rogerpack2005@…]

Just ran into this doing "sudo port install bittorrent" Fixing it would be kind :)

Please fix this. I can't install SPE.

Just to clearly state the problem: wxWidgets26 uses MoreFilesX internally, which defines a function called FSVolumeMount. Leopard ​introduced an identically-named function in Carbon. A fix would have to remove or rename MoreFilesX's version of the function, depending on whether it is equivalent to Carbon's version.

Well, I got that fixed, but then the next incompatibility appeared:

../src/mac/carbon/thread.cpp:1022: error: invalid conversion from 'long int' to 'void*'
../src/mac/carbon/thread.cpp:1022: error:   initializing argument 2 of 'OSStatus MPSetTaskStorageValue(TaskStorageIndex, void*)'.

That is a type conversion thing that can be fixed. If all the problems are type conversions only, there is hope. However, it is totally possible that the package can be built, but it does not work, which is the worst case. But we'll see...

Ok, now this builds on Leopard with patches added in r54612.
