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...

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 ...

Thanks. That fixed it. It build now with no error. I've uploaded the good build log to same link I have given above to confirm. >giac --version // Using locale /usr/local/share/locale/ // en_US.UTF-8 // /usr/local/share/locale/ // giac // UTF-8 // Maximum number of parallel threads 4 // (c) 2001, 20...

On same Linux where I build 1.9.0-53 OK few days ago, now I downloaded 1.9.0-55 and it gives an error building. I have not made any changes to the system during this time. This is on Linux >uname -a Linux me-virtualbox 6.1.19-1-MANJARO #1 SMP PREEMPT_DYNAMIC Mon Mar 13 12:59:35 UTC 2023 x86_64 GNU/L...

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...

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...

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 ...

Is there a command to find the full version of giac, including minor version? I installed giac giac_1.9.0-37.tar.gz from https://www-fourier.ujf-grenoble.fr/~parisse/debian/dists/stable/main/source/ but the command version only returns 1.9.0 0>> version() "giac 1.9.0, (c) B. Parisse and R. De Graeve...

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...

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.

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, ...
