          Issue ID: 126414
        Issue Type: DEFECT
           Summary: missing -fPIC flag
           Product: General
           Version: 4.2.0-dev
          Hardware: PC
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P5
         Component: code
          Assignee: issues@openoffice.apache.org
          Reporter: hramrach@gmail.com

When building openoffice the build fails due to something missing -fPIC flag. I
am building on Linux AMD64.


I added -fPIC to ARCH_FLAGS and the build seems to proceed much further.

This needs further investigation as to where the flag is missing. The object
where the build fails probably links to something that should have been built
with -fPIC but is not.

hmm, to the best of my knowledge both fmgridif.c and the directory containing
WindowListenerMultiplexer are built with -fPIC so the error is misleading at
best.

g++ (Debian 4.9.2-10) 4.9.2

ok, I have the exact error now:

[ build LNK ] Library/libsvxcore.so
/scratch/build/aoo/main/solver/420/unxlngx6.pro/workdir/CxxObject/svx/source/fmcomp/fmgridif.o:

So adding -fPIC to flags at random does not help.
