[PURRS-devel] Giac 0.4.0 and GCC 3.4.0

[Roberto Bagnara]

Dear Sir,

I have downloaded Giac 0.4.0 from

   ftp://ftp-fourier.ujf-grenoble.fr/xcas/giac_unstable.tgz

and tried to compile it with GCC 3.4.0.  The compilation
aborts very soon as follows:

...
c++ -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -g -O2 -c gausspol.cc  -fPIC -DPIC -o
.libs/gausspol.lo

monomial.h:151: error: base operand of `->' is not a pointer
monomial.h:302: confused by earlier errors, bailing out

make[1]: Leaving directory `/usr/local/distrib/giac-0.4.0'
make: *** [all-recursive-am] Error 2

I am unsure about whether this is an indication that Giac 0.4.0
uses some non-standard C++ features that are now rejected by
g++ or if we are presented with a bug in g++.
What do you think?
All the best, and thanks in advance for your time.
