[sword-devel] How do you make the Sword framework work in 64bit mode? (My compiler is giving me hundreds of warnings.)

Hi,

Ok, so I was able to download Revision 3441 which I think is the most recent version of SWORD? (at least at the time.)

I’ve been working on getting it to work with the PocketSword code. There’s a bit of code and changes which needed to be made in order for it to work. I thought I could just replace the old code, but it doesn’t work like that. Are these changes documented anywhere? There’s only some listed in the SWORD-HOWTO named file that’s in the /objc/doc folder of the Bindings folder. I’ve been troubleshooting through in order to get things working. Also, I eventually wound up running a comparison of the entire Sword folder to what currently exists in order to find the differences in the code parts.

Has there been any more updates on the code to make it more 64-bit ? 
It’s a lot better, but there’s still a lot of warnings regarding the matter that Xcode gives me. I’m considering the CLucene warnings as part of it all as well though I’m not sure if I should or not?

There also seems to be a couple of bugs or so, which I’ll put in the tracker.

Also, I’m not sure if it matters or not, but just fyi, Xcode 7.3.1 uses C99 for the C language dialect.

This should remove most of these warnings for you.  Have you actually had a problem compiling SWORD for 64bit or were just concerned about warnings?  Manfred and Nic should be able to answer better, but I'm quite sure we've been running 64bit on OSX for quite some time; not sure about iOS.

I hope it’ll help you better identify and understand the warnings and/or type of warnings that we are seeing. I’m not really that familiar with how clang and llvm nor autotools works so I don’t know what changes to suggest so this is the next best thing that I thought of. (Perhaps it is something I should investigate…?)

The first number is the row number in which the error occurs and then the second number is the number of spaces from the left that the warning is at. (Tabs/indents seem to count as one space)
