Checking in perl5-base/patches/patch-ag: 1.2 : 1 : 999

descr
|
|
The Xerces-Perl module is implemented as a shared object. It needs
|
|
some symbols from libgcc.a, such as __eh_alloc. It's not possible
|
|
to link the xerces-P shared object with libgcc.a, because libgcc.a
|
|
is not compiled with -fPIC. Hence we need to have the missing
|
|
symbols in the Perl executable.
|
|
This hack includes the whole libgcc.a in the Perl executable, and
|
|
links with c++ so that some mandatory symbols such as __pure_virtual
|
|
are also included. It should go away with GCC-3.0, or if we make a
|
|
libgcc.so on day.

reorder the -l flags on the link line but the general hack is to

disable versioned symbols.
