Subject troubles dealing with APR_HAS_LARGE_FILES=0
Date Mon, 12 May 2003 05:38:52 GMT
I'm trying to figure out why do I get APR_HAS_LARGE_FILES set to zero on my 
linux box. I can't find any rules that makes that decision. From reading 
archives, I understood, that it's simply unconditionally turned off.
The most recent thread on this topic seems to be:

we have a problem with mod_perl 2.0, when perl compiled with uselargefiles 
support (which is probably 99% of builds) used with Apache 2. The two are 
binary incompatible.

So far we were using the lowest common denominator flags, simply ripping off 
the '-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64' flags and refusing apr_seek() 
if offset is not zero (fun!). Now we have a bigger trouble, perlio layer calls 
the apr_seek wrapper with off_t=8, and the wrapper compiled with off_t=4. We 
obviously get wrong arguments ('whence' gets corrupted), because of the binary 

Any ideas, how to deal with this problem? (Other than telling all users to 
rebuild their perl without largefile support, which is impractical, because 
people need it.)
