I have some hints that could fix the problem, but I can not test them since I don't have gcc 3.4 installed.

Dear Bernard, please let me know if I can help (e.g., by giving you access to a machine with gcc 3.4.1).

The template code for Normalrref is never instantiated, that's why the error does not appear with previous versions of gcc. Declaring temp and newcoord as vector< monomial<T> > should fix the compilation error.

OK.

zero is assumed to be declared of type T when these functions are instantiated. I don't know how to declare zero as a template variable (would extern T zero; work inside a function?)

Yes, if this is what you want. However, this conflicts with the declaration extern gen zero; in gen.h.

gcc is correct, f. should be removed (twice)

OK. We still have the following problems (apart from the conflicting declarations for zero): c++ -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -g -O2 -c gausspol.cc -fPIC -DPIC -o .libs/gausspol.lo gausspol.cc: In function `bool giac::gcd_modular_algo(giac::polynome&, giac::polynome&, giac::polynome&)': gausspol.cc:982: error: no match for call to `(giac::polynome) (giac::polynome&, giac::polynome&, giac::gen&)' poly.h:385: note: candidates are: giac::tensor<T> giac::tensor<T>::operator()(const T&) const [with T = giac::gen] poly.h:266: note: T& giac::tensor<T>::operator()(const giac::index_m&) [with T = giac::gen] poly.h:277: note: const T& giac::tensor<T>::operator()(const giac::index_m&) const [with T = giac::gen] The following is cured by adding an include of <iostream> in global.h c++ -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -g -O2 -c ti89.cc -fPIC -DPIC -o .libs/ti89.lo In file included from misc.h:23, from ti89.cc:25: global.h: In member function `void giac::dbgprint_vector<T>::dbgprint()': global.h:130: error: `cout' is not a member of `std' A similar problem with cerr is in monomial.h.
