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.

Oddly this does not occur using the mipspro compiler. Possible

reason: using gcc we have longer CFLAGS. Fix: add USE_GNU_TOOLS+=awk

iff IRIX and gcc. Problem: this might affect other packages as well.

One might consider depending libtool on gawk for IRIX.
