Compilation error with cdefs.h
mruprich opened this issue · comments
I've hit this issue on ppc64le only but it has something to do with the bundled cdefs.h file. Basically one day, suddenly lftp stopped building in Fedora Rawhide with bunch of errors:

The list goes on but it is actually a result of lftp not being built with the system cdefs.h. This is the latest cdefs.h file:
https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/cdefs.h;h=44d3826bca9f6f84f862acf1035408a587fac71d;hb=HEAD
I was trying to figure out why the system cdefs.h is not used even though the configure script checks for it. But in the end every build has a resulting Makefile that has the HAVE_SYS_CDEFS_H set to an empty string(Not 1 or 0 but actually empty). Not sure if this is intentional but lftp should either actually use the system cdefs.h or at least the bundled file could be updated to the latest version.
