Hi
Im trying to compile a package called squid_auth_kerb in 12.04. I also tested
it in 11.10 with the same result. It works in 10.04 without problems.
aptitude install build-essential libgss-dev libkrb5-dev libssl-dev
libldap-dev libsasl2-dev krb5-user
cd /usr/local/src
wget
http://downloads.sourceforge.net/project/squidkerbauth/squidkerbauth/squid_kerb_auth-1.0.7/squid_kerb_auth-1.0.7.tar.gz
tar -xzvf squid_kerb_auth-1.0.7.tar.gz
cd squid_kerb_auth-1.0.7/
./configure
- configure complains about missing spnego support in = 11.10 and works in
10.04 !!!
make
dies with:
b5 -lk5crypto -lcom_err -L../../../lib -o squid_kerb_auth squid_kerb_auth.o
base64.o derparse.o spnego.o spnegohelp.o spnegoparse.o
squid_kerb_auth.o: In function `check_gss_err':
/usr/local/src/squid_kerb_auth-1.0.7/squid_kerb_auth.c:180: undefined

/usr/local/src/squid_kerb_auth-1.0.7/squid_kerb_auth.c:177: undefined

...
Works with 10.04
If I try to compile squid_auth_ldap in 12.04 it also gives me a problem
(works in 10.04)
wget
http://downloads.sourceforge.net/project/squidkerbauth/squidkerbldap/squid_kerb_ldap-1.2.2/squid_kerb_ldap-1.2.2.tar.gz
tar -xzvf squid_kerb_ldap-1.2.2.tar.gz
cd squid_kerb_ldap-1.2.2/
./configure
missing-prototypes -Wmissing-declarations -Wdeclaration-after-statement
-Wshadow -L/usr/lib/x86_64-linux-gnu -Wl,-Bsymbolic-functions -lgssapi_krb5
-lkrb5 -lk5crypto -lcom_err -o squid_kerb_ldap squid_kerb_ldap.o

/usr/bin/ld: note: 'krb5_kt_free_entry@@krb5_3_MIT' is defined in DSO
/usr/lib/x86_64-linux-gnu/libkrb5.so so try adding it to the linker command
line
/usr/lib/x86_64-linux-gnu/libkrb5.so: could not read symbols: Invalid
operation
collect2: ld returned 1 exit status
I can get a bit further by manually editing the Makefile after the configure.
But not all the way.
So anyone have an idea what changed and how do I fix it? Is the source broken
with 11.10 or is 11.10+ broken?
This is happening as a result of the --as-needed linker change in 11.10.
Add '--no-as-needed' to LDFLAGS and it should build fine. Long term you
should report this to the upstream project as they are linking to libldap
incorrectly by putting it in LDFLAGS instead of in LIBS, which is why
it is listed after the object files in the ld command line above. You
did not post the full ld line for the krb5 linking, but it seems likely
that it also suffers from this problem.
