Ticket History #7146: Kerberos compile on AIX 6.1 fails to detect as AIX

        

 

   Submitter-Id:  Sanford

   Originator:       Josh Peacock

   Organization: Sanford Health

   Confidential:   no

   Synopsis:          Misspelled "Kerberos" in title of installation guide

   Severity:           non-critical

   Priority:             low

   Category:         krb5-doc

   Class:                  doc-bug

   Release:            1.10.1 or 1.9.3

   Environment:

                IBM Power 750

                IBM AIX 6.1 TL 6 SP 6

 

     System:  AIX jpaixtmp 1 6 00F635E24C00

          >Description:

            

Using GCC to compile on AIX 6.1 results in the following error every time.

 

1.10.1 config.log shows

 

krb5_cv_host=powerpc-ibm-aix6.1.0.0

 

1.9.3 config.log shows

 

krb5_cv_host=rs6000-ibm-aix

 

When config/shlib.conf starts to work on this variable the case statement isn’t able to properly identify the host.

 

How-To-Repeat:

 

cd src/

 

env CC="gcc -O2 -Wall -Wl,-blibpath:/opt/pware/lib:/usr/lib:/lib,-brtl" \

CPPFLAGS="-I/opt/pware/include" \

LDFLAGS="-L/opt/pware/lib" \

DBLIB=-ldb \

./configure --prefix=/opt/pware  --enable-shared

 

make

           

Fix:

            

In shlib.conf I think it would be best to move the case statement for aix4 above the aix5 statement and then make the match be *-*-aix* which would act as a catch all for aix and if there were specific changes for an AIX level that could be added above the AIX catch all statement.  I attempted to create a patch file, but it wasn’t happy about the lines starting in a “-“.  Below is the aix chunks from version 1.9.3.
