I have the same problem on AIX v5 under 5.8.0, but I think I've solved it. main.c contains a static PerlInterpreter declaration on line 24: static PerlInterpreter *my_perl; But mktmpdir.c (which is included from main.c on line 14) indirectly needs to have access to this interpreter. On line 169, it calls readdir: while ( ( dp = readdir(partmp_dirp) ) != NULL ) { But under a threaded perl, a call to readdir() becomes this instead: ((((*_Errno()) = readdir_r(partmp_dirp, (my_perl->Ireentrant_buffer)- Show quoted text

>_readdir_struct, &(my_perl->Ireentrant_buffer)->_readdir_ptr)))

Which produces said error. I'm not sure if this is the best way to solve it, but by removing the static qualifier in main.c and adding an extern declaration in mktmpdir.c, I was able to get past this problem. I still can't build PAR mind you: now it blows up with this error: ld: 0711-327 WARNING: Entry point not found: __start when trying to link 'par', but this error has been plaguing me on AIX as long as PAR has been around so I don't think it is related to the my_perl problems above. If you're not on AIX you probably won't be affected by this. Regards.

This has been fixed in 0.71 by using PL_statbuf. /Autrijus/
