MinGW Compiler support for Scilab on Windows
You need to install MinGW gcc package distributed by Equation Solution first
(subsequent versions of gcc should work as well).
Both 32 and 64 bit versions of the MinGW gcc package (gcc-10.3.0-32.exe and
gcc-10.3.0-64.exe files) can be found in the "Files" section of the
MinGW Toolbox page at
https://atoms.scilab.org/toolboxes/mingw/10.3.0/files/gcc-10.3.0-32.exe
https://atoms.scilab.org/toolboxes/mingw/10.3.0/files/gcc-10.3.0-64.exe
After installing the MinGW package, logout/login your Windows session and
finally install the MinGW Scilab toolbox. The first time you load the toolbox,
Scilab will rebuild some gcc libraries. The process may take a minute or more so
please be patient and wait until Scilab returns control to the command prompt.
