Issue ID: 10581 Summary: Mismatch of crypt() prototype on PPC Mac OS X 10.5.8, Leopard Product: OpenLDAP Version: 2.6.14 Hardware: Other OS: Mac OS Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: build Assignee: bugs@openldap.org Reporter: Peter_Dyballa@Web.DE Target Milestone: ---

This happens with OpenLDAP versions 2.6.13 and 2.61.4:

/opt/local/bin/gcc-mp-15 -pipe -Os -arch ppc -I../../include -I../../include -isystem/opt/local/include/LegacySupport -I/opt/local/include -I/opt/local/include/db48 -I/opt/local/include/openssl -DBIND_8_COMPAT -DMDB_FDATASYNC=fsync -DMDB_DSYNC=O_SYNC -c -o passwd.o passwd.c In file included from passwd.c:38: ../../include/ac/crypt.h:26:23: error: conflicting types for 'crypt'; have 'char *(void)' 26 | extern char *(crypt)(); | ^~~~~ In file included from /opt/local/include/LegacySupport/unistd.h:87, from ../../include/ac/unistd.h:25, from passwd.c:34: /usr/include/unistd.h:424:10: note: previous declaration of 'crypt' with type 'char *(const char *, const char *)' 424 | char *crypt(const char *, const char *); | ^~~~~ passwd.c: In function 'lutil_crypt': passwd.c:627:20: error: too many arguments to function 'crypt'; expected 0, have 2 627 | char *cr = crypt( key, salt ); | ^~~~~ ~~~ ../../include/ac/crypt.h:26:23: note: declared here 26 | extern char *(crypt)(); | ^~~~~ make[2]: *** [passwd.o] Error 1 make[2]: Leaving directory `/opt/local/var/macports/build/openldap-afe672a1/work/openldap-2.6.14/libraries/liblutil' make[1]: *** [all-common] Error 1 make[1]: Leaving directory `/opt/local/var/macports/build/openldap-afe672a1/work/openldap-2.6.14/libraries' make: *** [all-common] Error 1 make: Leaving directory `/opt/local/var/macports/build/openldap-afe672a1/work/openldap-2.6.14' Command failed: cd "/opt/local/var/macports/build/openldap-afe672a1/work/openldap-2.6.14" && /usr/bin/make -w all Exit code: 2

On Leopard /usr/include/unistd.h has:

char *crypt(const char *, const char *);

So I ended applying this simple patch:

--- include/ac/crypt.h~ 2026-08-06 18:45:16.000000000 +0200 +++ include/ac/crypt.h 2026-08-30 11:21:21.000000000 +0200 @@ -22,8 +22,6 @@ /* crypt() may be defined in a separate include file */ #ifdef HAVE_CRYPT_H # include <crypt.h> -#else - extern char *(crypt)(); #endif

#endif /* _AC_CRYPT_H */

This happens when using the MacPorts package manager. The issue can be viewed (and also commented) here: https://trac.macports.org/ticket/73673.
