Hi,

Well, story goes on...

Mac OS X 10.3.7, XCode 1.5 with the november 2004, update, gcc 3.3.x =20
build 1671 from Apple

With gcc - fast -mdynamic-no-pic
FLIBS -lg2c
g77 -O5 -funroll-loops

apart the munge-texi broken cited above that need

cd doc/interpreter
g++ -o munge-texi munge-texi.cc
make

with a ./configure --enable-static --disable-readline

octave 2.1.64 compiles... but

but

at launch i've got a bus error...

Where's the gap ?

I'm trying to compile with shared libraries... and avoiding libtool =20
complain...

Samir
