Package: cpl Version: 6.4.1-5 Usertags: goto-cc During a rebuild of all packages in a clean sid chroot (and cowbuilder+pbuilder) the build failed with the following error. Please note that we use our research compiler tool-chain (using tools from the cbmc package), which permits extended reporting on type inconsistencies at link time.

error: conflicting function declarations "stat"
old definition in module cpl_fits file /usr/include/x86_64-linux-gnu/sys/stat.h
line 453
signed int (const char *__path, struct stat *__statbuf)
new definition in module cxfileutils file
/usr/include/x86_64-linux-gnu/sys/stat.h line 453
signed int (const char *__path, struct stat *__statbuf)
reason for conflict at __statbuf in types listed below (struct/struct):
composite type component counts differ (18/15)
struct stat {
unsigned long int st_dev;
unsigned long int st_ino;
unsigned long int st_nlink;
unsigned int st_mode;
unsigned int st_uid;
unsigned int st_gid;

struct stat {

signed long int st_blocks;

signed long int [3l] __unused;
}
This is caused by cpl_fits (and other files) being compiled with
-D_POSIX_C_SOURCE=200112L only, whereas cxfileutils is being compiled with
-D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=500 -- the difference in
_POSIX_C_SOURCE may be tolerable, but inconsistent use of _XOPEN_SOURCE is not.
