Dear Cherif and Samir,
I apologize for the delay in answeing your requests for help, but I only managed to look at this today.
After a Sunday spent curs^H^H^H^Hworking at PURRS, I have made some progress toward making it buildable again. The depinst script is totally outdated, so I did not use it. What I did, was the following:
wget ftp://ftp.gnu.org/gnu/cgicc/cgicc-3.2.9.tar.gz tar zxf cgicc-3.2.9.tar.gz cd cgicc-3.2.9 ./configure make sudo make install
wget http://www.ginac.de/CLN/cln-1.3.1.tar.bz2 tar jxf cln-1.3.1.tar.bz2 cd cln-1.3.1 ./configure make sudo make install
wget ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/ginac-1.5.6.tar.bz2 tar jxf ginac-1.5.6.tar.bz2 cd ginac-1.5.6 ./configure make sudo make install
wget http://www.shoup.net/ntl/ntl-5.5.2.tar.gz tar zxf ntl-5.5.2.tar.gz cd ntl-5.5.2/src ./configure CFLAGS="-O2 -fPIC" NTL_GMP_LIP=on NTL_STD_CXX=on make sudo make install
wget ftp://ftp-fourier.ujf-grenoble.fr/xcas/giac.tgz tar zxf giac.tgz cd giac-0.8.5 ./configure --disable-debug --disable-gc --without-x --disable-gui --disable-pari --disable-gsl make sudo make install
After which I had to make several changes to PURRS, and now it compiles. It fails its testsuite miserably, but I believe the reason is a change in the GiNaC expression parser that does not influence the PURRS library.
If you haven't lost interest and you want to try, please let me know the results. Don't forget to "cvs up" your local copy. All the best,
Roberto
