Problem: When using GCC 4.6 the configure script fails to find libreadline and libdl, although both libraries are definitely installed. See http://www.ginac.de/pipermail/ginac-list/2012-January/001868.html for more details. Reason: Apparently GCC 4.6 dislikes the -R/the/path switch (libtool way to say -Wl,-rpath,/the/path in a cross platform manner). Previous versions of GCC used to ignore the -R switch, however, GCC 4.6 errors out instead. Thus the configure script fails to detect readline and dlopen. Solution: Set the rpath (for linking with CLN) using the compiler friendly syntax (i.e. -Wl,-rpath -Wl,/the/path instead of -R/the/path). ----------------------------------------------------------------------- Summary of changes: configure.ac | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

Question

Hello, when I do (e.g. in ginsh) -a * (r^n-R^n); I get a * (R^n-r^n) for n <= 3 but -a * (r^n-R^n) for n> 3 Why? Jan

bugs related to parser
by Cedric Studerus 06 Dec '11

06 Dec '11

Dear GiNaC developer, I'm using GiNaC version 1.6.2 with compiler gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2 When working with the parser to read in user defined functions from strings I noticed 3 things: 1) parsing a user defined function (declared to have 1 argument) from a string does not throw an exception when the string contains this function with zero arguments. 2) parsing products of user defined non-commutative functions returns a commutative product 3) The parser accepts userdefined functions with zero arguments and parsing such a function does not throw when there is 1 argument. I have attached a small file "main.cpp" such that you can reproduce this behavior. I'm using these user defined functions with zero arguments but it looks to me like a hack and I would like to know if you are going to allow them ( e.g. with macro definition) or if you completely suppress them in future releases of GiNaC. Thank you very much! Cedric Studerus

Release 1.6.2
by Jens Vollinga 06 Nov '11

06 Nov '11

Hi everybody, GiNaC 1.6.6 is out and available. The changes are the following: * Fixed the parser to read GiNaC::lst again. * Fixed a compile warning (relevant to openSUSE build). * Fixed a bug concerning the subsitutions in indexed expressions (subs_options::no_index_renaming was ignored). As always, this release can be downloaded from http://www.ginac.de/Download.html Regards, Jens
