Package: dpkg
Version: 1.4.1.6
Severity: normal
Hello world,
dpkg installs dpkg.h in /usr/share/include/dpkg/, which gcc doesn't search
by default. /usr/include would seem a more sensible place.
Also, since dpkg-dev and dpkg both use /usr/doc/dpkg, the /usr/doc/dpkg
symlink to /usr/share/doc/dpkg wasn't made. apt-get install dpkg;
apt-get install dpkg-dev should be enough to duplicate this. I'd suggest
adding a Conflicts: line to make sure they're both upgraded concurrently.
#include <dpkg/dpkg.h> gives errors unless the following symbols are defined:
#define NONRETURNING
#define NONRETURNPRINTFFORMAT(a,b)
#define PRINTFFORMAT(a,b)
dpkg itself defines them in a meaningful way, these definitions should
probably be moved into dpkg.h itself.
Finally, and as more of a wishlist item, it'd be nice if the cmpversions()
function from main/enquiry.c was included in libdpkg itself. A possible
implementation might be:
#define NONRETURNING
#define NONRETURNPRINTFFORMAT(a,b)
#define PRINTFFORMAT(a,b)
#include <dpkg/dpkg.h>
#include <dpkg/dpkg-db.h>
const char thisname[] = "main"; /* defined separately in each program */
const char printforhelp[] = "foo";
/* returns:
* 0 if true
* 1 if false
*
* -1 for bad operand
* -2 for bad version
*
* eg,
* 0 == cmpversions("2.0-1", "<<", "3.4-4");
*/
static int cmpversions(char *left, char *op, char *right) {
struct relationinfo {
const char *string;
/* These values are exit status codes, so 0=true, 1=false */
int if_lesser, if_equal, if_greater;
int if_none_a, if_none_both, if_none_b;
};
static const struct relationinfo relationinfos[]= {
/* < = > !a!2!b */
{ "le", 0,0,1, 0,0,1 },
