Issue ID: 9658 Summary: libldap fails to compile on Hurd: MAXPATHLEN undeclared Product: OpenLDAP Version: 2.5.7 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: build Assignee: bugs@openldap.org Reporter: ryan@openldap.org Target Milestone: ---

OpenLDAP 2.5 and later fails to compile on GNU/Hurd:

libtool: compile: cc -g -O2 -I../../include -I../../include -DLDAP_LIBRARY -c request.c -fPIC -DPIC -o .libs/request.o In file included from ldap-int.h:119, from request.c:53: request.c: In function 'ldap_dump_connection': ../../include/ldap_pvt.h:181:25: error: 'MAXPATHLEN' undeclared (first use in this function) 181 | #define LDAP_IPADDRLEN (MAXPATHLEN + sizeof("PATH=")) | ^~~~~~~~~~ request.c:859:17: note: in expansion of macro 'LDAP_IPADDRLEN' 859 | char from[LDAP_IPADDRLEN]; | ^~~~~~~~~~~~~~ ../../include/ldap_pvt.h:181:25: note: each undeclared identifier is reported only once for each function it appears in 181 | #define LDAP_IPADDRLEN (MAXPATHLEN + sizeof("PATH=")) | ^~~~~~~~~~ request.c:859:17: note: in expansion of macro 'LDAP_IPADDRLEN' 859 | char from[LDAP_IPADDRLEN]; | ^~~~~~~~~~~~~~ Makefile:435: recipe for target 'request.lo' failed make[2]: *** [request.lo] Error 1

This is not the same as ITS#9648. I have pulled latest master and the patch for that one does not solve it.

GNU/Hurd actually does not have a MAXPATHLEN constant at all; paths are expected to be dynamically allocated. See: https://www.gnu.org/software/hurd/hurd/porting/guidelines.html#PATH_MAX_tt_M...

This is a low priority issue for me personally. I'm just filing it for tracking. I'm hoping someone from the GNU/Hurd community might be able to work on a patch.
