Topic : Problem compiling krb5 1.17 under AIX 7.2.
Dear Kerberos developers,
I know that AIX is no longer a supported platform for Kerberos but help
would be really appreciated!
I am on the latest AIX 7.2 ppc and have problems compiling/linking latest
Kerberos 5 1.17.
I am trying to compile with native xlc.
Here is what I did:
$ export CC="xlc_r"
# Fix for unsupported AIX version, see
http://kerberos.996246.n3.nabble.com/MIT-krb5-1-12-1-configure-fails-on-AIX-6-1-and-7-1-td39461.html
$ cd ./src
$ /usr/bin/perl -i -pe "s/aix5/aix[567]/" config/shlib.conf
# Fix configure script, see
http://kerberos.996246.n3.nabble.com/Missing-lpthreads-breaks-build-in-plugins-tls-k5tls-on-AIX-td47390.html
# change in configure and configure.in:
-TLS_IMPL_LIBS = -lssl -lcrypto
+TLS_IMPL_LIBS = -lssl -lcrypto -pthread
# C-FLAG qlanglvl=extc99 is needed because of errors without it, see samba
mail list
https://lists.samba.org/archive/samba-technical/2006-October/049722.html
$ ./configure CFLAGS="-qlanglvl=extc99"
--prefix=/oli-compile/krb5-1.17/build
# Run make
$ /bin/make
# Make throws errors, as AIX does only work with .a archive files
$ cd ./lib
$ for i in *.so; do /bin/ar -v -q `basename $i .so`.a $i; done
$ cd ..
# Run make again
$ /bin/make
# Runs further but needs a fix again, as libkadm5srv_mit is also only .so
$ cd ./lib
$ /bin/ar -v -q libkadm5srv_mit.a libkadm5srv_mit.so
$ cd ..
# Run make again
$ cd ..
$ make
# Runs further, now another missing dep: libdb, for fix see
http://kerberos.996246.n3.nabble.com/KRB5-1-5-or-1-6-compiled-on-AIX-5-2-5-3-td15834.html
$ cd ./lib
$ ln -s ../plugins/kdb/db2/libdb2/libdb.so.1.1 libdb.so.1.1
$ ln -s libdb.so.1.1 libdb.so
$ cd ..
$ make
# again missing dep:
$ cd lib/
$ /bin/ar -v -q libkadm5clnt_mit.a libkadm5clnt_mit.so
$ cd ..
$ make
# now make finishes without any further errors!!! but "make check" and all
binaries throws following error:
# e.g. kinit
$ LIBPATH=/oli-compile/krb5-1.17/build/lib/ ./kinit
The assert subroutine failed: destructors_set[keynum] == 0, file threads.c,
line 353
IOT/Abort trap (core dumped)

# It looks strange to me that several libs have been imported twice (e.g.
libpthreads.a) and also that it uses .so and .a of the same lib.
# Another view using the dump command:
$ LIBPATH=/oli-compile/krb5-1.17/build/lib/ dump -H ./kinit
./kinit:

I would really like to solve the problems, can someone help me finding the
issues about it?
Thank you very much for your help!!!
Oliver
