Re^3: Win32, MinGW and -Duse64bitint

Sorry, you're right: it's config.gc, not config.w32.

The perl source is distributed with read-only permissions set; try chmod a+w config.gc or attrib -r config.gc.

try chmod a+w config.gc Thanks ... that seems to do the trick. (I didn't try the 'attrib' command.) But I don't understand why it was necessary to do that - given that a right click on the file in Winders Explorer, select "properties" and then de-select "Readonly" seemed to do what I wanted. Anyway, having modified config.gc to 'define' use64bitint, I find that I get: `C:\_32\perl-5.8.8\win32>perl -V:use64bitint use64bitint='define'; C:\_32\perl-5.8.8\win32>perl -e "print ~0" 4294967295 C:\_32\perl-5.8.8\win32>` [download] If I had really got the 64-bit support that I was seeking that last command would have produced 18446744073709551615. There's obviously other stuff that needs to be done. (But ++ for the help, so far, ysth) Cheers, Rob	[reply] [d/l]

Right, next you need to change all the other values that Configure would set differently when use64bitint is set. Probably easiest to just go through all of config.gc, line by line. There's documentation in Porting/Glossary. I'm looking for a job.	[reply]
