Compiling libj runs into problem with gcc -W switches

[brickviking]

I thought I'd compile J, but while I can compile jconsole fine, I ran into a problem when trying to compile libj. I did manage to compile some files, but I'll include some pertinent information here:

So, where do I go from here? I'm not really a good programmer, so I'm lost as to where to start. I rather hope I haven't flooded you with information, but it's all the info I thought might have been relevant, except for memory/cpu/hard drive space etc.

Hopefully, brickviking

[bilam]

fixed. please try again.

[brickviking]

Thank you. I'm left with another error, I'll get that into here in a mo.

Hope this will be the last one, as I'm not sure what switch I'd have needed to "cure" this problem.

[bilam]

I have fixed this, and will update when I have fixed other bugs for j64x=j64 with gcc.

[brickviking]

Okay, thanks for the time you're spending with this. I know roughly how to run the compiler, but I've never quite figured out all the -W and -f switches, usually I have configure/make along for the ride.

[bilam]

Fixed. Still some abi warnings on gcc but didn't look into it.

[brickviking]

Thank you again. That's fixed all the remaining bugs I think I had. I'll rerun it again from scratch and find out if it works properly.

Later: yup. All compiled fine. I'm done for the moment.

Cheers, brickviking.
