Hi,
I had upgraded GiNaC from 1.2.4 to 1.3.0 in the process of compiling PyGiNaC (after realising that it was indeed needed) Can you be more specific about this need? PyGiNaC is supposed to be buildable against GiNaC 1.2.x.
Sorry for the late reply but yes, I can. Trying to build against GiNaC 1.2.4, I get the following error during compilation. scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... g++ -pipe -march=pentium3 -g -Wall -W -Wsign-compare -Wconversion -std=c++98 -Wdisabled-optimization -pedantic -Wno-unused-parameter -fPIC -DPYGINAC_AVOID_EX -Iinclude -I/usr/include/python2.3 -I/usr/local/include -c -o src/basic.os src/basic.cpp src/basic.cpp: In function `void pyginac::wrap_basic()': src/basic.cpp:420: error: `eval_integ' is not a member of type `GiNaC::basic' scons: *** [src/basic.os] Error 1 scons: building terminated because of errors. If I recall correctly, eval_integ was introduced in 1.3.0 (the basic symbolic integration stuff).
