Re: disable generating warning messages from integrate command?
Maybe try to modify icas.cc and redirect logs with logptr(0,contextptr) before any evaluation. Sorry, I do not know how to do that. I am not going to dig into advanced and complex C++ code and try to change things I do not understand. I was hoping you could provide a configuration switch to turn th...

disable generating warning messages from integrate command?
Is there a global option to set in giac to disable generating warning messages that show before the result of integration? I will an example below. The reason I am asking, is that I am calling giac from sagemath. And sagemath gives an exception when it gets back result with these warning in them as ...

Re: How to obtain complete version information for giac?
Thanks. That worked. I found I had to edit both config.h files. For those who want to do this, here are the steps again 1) extract tar file 1A) edited as root the file /etc/ld.so.conf and added this new line at the top /usr/local/lib of the file and saved it. 2) ./configure 3) edit config.h file in sr...

Re: How to obtain complete version information for giac?
This is not supported, unless you modify config.h yourself (after configure) and change VERSION by hand. The reason is that the only way I know to upgrade from 1.9.0 to say 1.9.1 requires too many changes by hand. Therefore I do that at most once per year... OK, no problem, I can do that. I see two...

Re: How to obtain complete version information for giac?
This did not work for me. I am on Linux (so no .DLL) but tried your command on the libgiac.so I found in /usr/local/lib, but it does not give the version string. >locate giac.so /usr/lib/libgiac.so /usr/lib/libgiac.so.0 /usr/lib/libgiac.so.0.0.0 /usr/local/lib/libgiac.so /usr/local/lib/libgiac.so.0 ...

How to obtain complete version information for giac?
Is there a command to find the full version of giac, including minor version?

using giac to solve differential equation with initial conditions
Using giac 1.9-35. When I put the initial conditions in a variable first, then call desolve, it does not work. If I put the initial conditions directly into the desolve command, it works. Why is that? Here is an example >> ode:=diff(y(t),t)+y(t)=0 diff(y(t),t)+y(t)=0 >> desolve([ode,y(0)=1],y(t)) ex...

Re: Build error for 1.9-13 on Linux
I ended up using Manjaro Pacman package manager to install giac 1.9-0-11.1 and that worked with no problem.
I have no idea why the manual installation failed. I was hoping to use 1.9-0-13 but can't build it and it is not yet available in the package manager yet.

Re: Build error for 1.9-13 on Linux
fyi; Maybe the problem is due to some system issue. Because I downloaod 1.9-11 giac tar file and compiled it, and it gives same error. Also this time I installed micropython 1.18.1 in case it is needed (I was not sure). gausspol.h: In function ‘int giac::coeff_type(const std::vector<T_unsigned<gen, ...
