Hi!

I have a very subtile problem with KDE libraries on solaris 7.
It has come up since the developers decided to use libtool for linking
shared libraries instead of plain g++.

The problem arises on libraries which have global Variables of complex types in
it (this is for example libkab).

It can be reproduced with the following:

main program:

extern string x

int main () {
	x = "blaBla"
}

library:

string x;

This crashes, when the library linked with libtool, but not when linked with
g++ -shared.

The reaseon is that libtool doesn't use g++ anymore but straight /usr/cc/bin/ld
(why?) and then there are som g++ initialization modules missing in the .so.

g++ -shared uses this much more complex ld command line (for my test library),
and that works: 
ld -V -G -dy -z text -h libkabtest.so -Y P,/usr/ccs/lib:/usr/lib
-Qy -o libkabtest.so  /appl/lib/gcc-lib/sparc-sun-solaris2.7/2.7.2.2/crti.o
/usr/ccs/lib/values-Xa.o
/appl/lib/gcc-lib/sparc-sun-solaris2.7/2.7.2.2/crtbegin.o
-L/appl/lib/gcc-lib/sparc-sun-solaris2.7/2.7.2.2 -L/usr/ccs/bin -L/usr/ccs/lib
-L/appl/lib libkabtest.o -lg++ -lstdc++ -lm
/appl/lib/gcc-lib/sparc-sun-solaris2.7/2.7.2.2/crtend.o
/appl/lib/gcc-lib/sparc-sun-solaris2.7/2.7.2.2/crtn.o



Question: Does anybody know how to convince libtool not to use ld directly?
Ist there a switch in configer?
Or do I have to use GNU ld and recompile my gcc (not wanted at all)?

Thanks for listening,
Michael

P.S: My system is Sun Ultra 5 with Solaris 7 and gcc 2.7.2.2
