Hi all
I write this to you in an attempt to solve a recurring problem I'm
having with libh that is *really* hindering development, for me. I'm
currently trying to rewrite our pkg_create sh script in C++ (from a sh
script). I just checked-in the source in libh/bin/pkg_create. You
haven't seen the mail because of DNS problems on rtp1.
Anyways, I'm having problem linking the final program. I've seen
similar problems when trying to switch to rhtvision and link other
programs against libh.
The source file is being properly compiled, g++ can find its headers,
etc, and I can generate the .o file. However, when trying to link, I
get:
g++31 -O -pipe -I../../include -I/usr/local/include/tcl8.3 -c pkg_crea=
te.cc
g++31 -O -pipe -I../../include -I/usr/local/include/tcl8.3 -L/usr/loc=
al/lib -L/usr/lib -o pkg_create pkg_create.o -ltcl83 -lh -lhtcl -lhdatabase=

Stop in /usr/home/anarcat/cvs-work/libh/bin/pkg_create.
I have just installed that library (libhsysinstall). What I don't
understand is that I can't find that damn symbol anywhere:
anarcat@lenny[~/libh/compile/none]% for f in libh* =20
do; nm -C $f 2>/dev/null | grep LanguageInterface::Language && echo "$f"
done

Some symbols are defined, however. For example, Shared::onHeap() is
defined in libh.so:
0003a746 T Shared::onHeap(void const*)
libh.so
The thing itself is kinda very important to libh. It is defined in
libh/include/LanguageInterface.hh:
class LanguageInterface
{
friend class H;
friend class HObjectsReferences;
public:
LanguageInterface( bool enableGC ) : mGC( enableGC ) {}
=2E..
}
Why it's not linking anywhere is beyond me.
Also, why tclh is linking at all is also a great mystery for me.
Please, any hint will help greatly. I'm completly confused and pretty
desperate to solve this problem.
If I can't get this program to link I don't see very well where we
should be going next. Is it really impossible/forbidden to link
against LibH?
A.
