Description hramrach 2015-07-20 10:58:11 UTC

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.

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: In function `FmXGridControl::createPeer(com::sun::star::uno::Reference<com::sun::star::awt::XToolkit> const&, com::sun::star::uno::Reference<com::sun::star::awt::XWindowPeer> const&)':

make: *** [/scratch/build/aoo/main/solver/420/unxlngx6.pro/workdir/LinkTarget/Library/libsvxcore.so] Error 1
dmake:  Error code 2, while making 'all'


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

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.
