Description c.kworr 2018-02-10 09:56:10 UTC
IF someone tries to use security/krb5 to stay MIT or security/heimdal to get a newer version of heimdal postgresql is one of packages that wouldn't work anymore out of the box.

So we have:

1. World WITHOUT_KERBEROS and WITHOUT_KERBEROS_SUPPORT.
2. Trying to build postgresql server.

Here we go down:

configure:3851: $? = 1
configure:3871: checking whether the C compiler works
configure:3893: clang60 -O3 -pipe -march=native  -O3 -funroll-loops -fstack-protector -fno-strict-aliasing -I/usr/local/include  -L/usr/local/lib -lpthread -lgssapi -L/usr/local/lib -Wl,-rpath,/usr/local/lib -fstack-protector conftest.c  > &5
/usr/local/bin/ld: cannot find -lgssapi

This happens because:

 - security/krb5 provides libgssapi_krb5 in /usr/local/lib (missed);
 - security/heimdal provides libgssapi in /usr/local/lib/heimdal (not included in -L)

Here's an example how this can be solved (I'm not good with options so this is just to show the concept):

OPTIONS_RADIO+=         GSSAPI
OPTIONS_RADIO_GSSAPI= GSSAPI_HEIMDAL GSSAPI_MIT
.if exists(/usr/lib/libgssapi.so) # ? didn't have it installed
OPTIONS_RADIO_GSSAPI+= GSSAPI_BASE
OPTIONS_DEFAULT+=      GSSAPI_BASE
GSSAPI_BASE_USES=              gssapi:base
GSSAPI_BASE_CONFIGURE_ON=      --with-gssapi
.endif

GSSAPI_HEIMDAL_USES=           gssapi:heimdal,flags
GSSAPI_HEIMDAL_CONFIGURE_ON=   --with-gssapi
GSSAPI_HEIMDAL_CFLAGS+=        -I/usr/local/include/heimdal
GSSAPI_HEIMDAL_LDLAGS+=        -L/usr/local/lib/heimdal
GSSAPI_HEIMDAL_LIB_DEPENDS+=   libgssapi.so:security/heimdal

GSSAPI_MIT_USES=               gssapi:mit
GSSAPI_MIT_CONFIGURE_ON=       --with-gssapi
GSSAPI_MIT_CFLAGS+=            -I/usr/local/include
GSSAPI_MIT_LDLAGS+=            -L/usr/local/lib
GSSAPI_MIT_LIB_DEPENDS+=       libgssapi_krb5.so:security/krb5
.endif

Hope this helps a little.

MIT KRB5 has no libgssapi. It is libgssapi_krb5. libgssapi is available in base and in the heimdal port.

Having said that, on my laptop I am able to successfully build postgres95-server:

I suspect that this may be an environmental issue.
Comment 2 Peter Much 2022-01-19 21:10:19 UTC
No, this is not an environmental issue. When setting options GSSAPI, the postgresql Makefile explicitely sets 'LDFLAGS+=-lgssapi', and therefore configure will always look for the Heimdal gssapi. 

If this were not set, then configure would at first look for a -lgssapi_krb5 and then for -lgssapi, and therefore would find a MIT kerberos even with an unmodified base containing the Heimdal gssapi.

The issue got more relevance since pgadmin4, since version 5.3, now uses Gssapi credstore extension, and this is currently only available in MIT. (Heimdal has it in head, but not in the current 7.7 release).

What you can do, is: compile and link the postgresql with Heimdal gssapi from base, and then force it to runtime-link with the MIT gssapi, by means of the appropriate LD_PRELOAD settings. Since gssapi is pretty standardized, and since the latter is a superset, this actually happens to work. (But I would not want to do this in production; it rather happened to me accidentially.)

I would much appreciate to get the radio buttons just like almost everything else in ports has them. I have built a separate instance WITHOUT_KERBEROS to run my pgadmin4, but I definitely do not want to also change my entire build&deploy scheme to also do WITHOUT_KERBEROS.
