Build with -D_FILE_OFFSET_BITS=64 on 32-bit Linux #2203

As otherwise, a bootstrap.dat over 2 GiB in size will fail to fopen(), let alone being able to seek in it.

Isn't that size limit also there on Windows?

@Diapolo pretty sure we'd have gotten tons of complaints from windows users if that was the case. Are you able to import from a >2GiB bootstrap.dat?

Diapolo commented at 10:25 AM on January 23, 2013: none

@sipa I never played around neither with that auto-import, nor with the normal -loadblock at all. Can you hand me the link to the bootstrap.dat download?

Just concatenate some block files.

Diapolo commented at 10:44 AM on January 23, 2013: none

Any way to do this in Windows, I dunno how ;). And you are talking about pre 0.8 block-files I guess (which I still have as I use the latest 0.7.2 for my main wallet).

sipa commented at 10:45 AM on January 23, 2013: member

Block file format didn't change (and the gaps caused by pre-allocation don't matter).

Install cygwin, run "cat blk*.dat >bootstrap.dat" ?

You are right, I forgot, that there was no format change ^^. Beat me, but cat is nothing I've ever heard of :-P.

sipa commented at 11:26 AM on January 23, 2013: member

cat = unix command to concatenate files :)

Diapolo commented at 12:38 PM on January 23, 2013: none

Importing now... resulting file size after cat is >6GB.

@sipa I had no problems while bootstrapping!

@Diapolo thanks, good to know. So the problem is really only on Linux 32-bit. Maybe OSX 32-bit as well, but I have no way to test that.

@gavinandresen DId you ever try importing a >2GiB file on 32-bit OSX builds?

gavinandresen commented at 1:34 AM on January 24, 2013: contributor

Importing >2GB file works fine on 32-bit OSX, at least with git HEAD.

Fixed by #2236
