Hello GiNaC! I downloaded GiNaC-0.8.3.tar.bz2, but I'm having trouble building it on my system. My computer has SuSE 7.1 with gcc version 2.96 20000731. Here's the build error: make[2]: Entering directory `/home/gg/down2/math/GiNaC-0.8.3/ginac' /bin/sh ../libtool --mode=compile c++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/local/include -g -O2 -c inifcns.cpp rm -f .libs/inifcns.lo c++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/local/include -g -O2 -c inifcns.cpp -fPIC -DPIC -o .libs/inifcns.lo In file included from inifcns.cpp:31: matrix.h:125: non-local function `GiNaC::ex GiNaC::determinant (const GiNaC::matrix &, unsigned int = GiNaC::determinant_algo::automatic)' uses anonymous type make[2]: *** [inifcns.lo] Error 1 make[2]: Leaving directory `/home/gg/down2/math/GiNaC-0.8.3/ginac' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/gg/down2/math/GiNaC-0.8.3' make: *** [all-recursive-am] Error 2 Thanks for any help, /george moudry los angeles PS. I saw on the ginac.de website that some people were installing an RPM. Would you know where to download it from? PPS. The GiNaC screenshot is incredible! I really did think it crashed my browser. - To UNSUBSCRIBE, email to ginac-list@ginac.de with a subject of "unsubscribe".
