Re: guile-1.8.3 Intel Mac Leopard compilation fails due to no off64_t

[Roger Mc Murtrie]

Similiar problem with filesys.c
Compiles by changing in _scm.h
#define dirent_or_dirent64               
CHOOSE_LARGEFILE(dirent,dirent64)
to
#define dirent_or_dirent64              dirent

Now some resulting link problems to sort out!
