MinGW Compiler support for Scilab 6.1.1 and more on Windows
You need to install MinGW package distributed by Equation Solution first
(subsequent versions of gcc should work as well):
Scilab 32 bits: http://www.equation.com/ftpdir/gcc/gcc-9.2.0-32.exe
Scilab 64 bits: http://www.equation.com/ftpdir/gcc/gcc-9.2.0-64.exe
Then logout/login your Windows session and finally install this toolbox. The
first time you load this toolbox Scilab will rebuild some gcc libraries. The
process may take a minute or more so please be patient.

I have not been able to get MinGW to find the gcc compiler.
When I start Scilab, I get the message:
Mingw Compiler support for Scilab
WARNING: MinGW Compiler not detected.
I've tried all sorts of things, but have now run gcc-9.2.0.exe, and added C:\MinGW\bin to
the System Path. I upgraded MinGW 8.3.0 to MinGW 9.2.0. I unistalled Scilab and did a
fresh install, loaded MinGW, exited and restarted Scilab but the above message didn't
How do I help MinGW 9.2.0 find the gcc compiler? There appears to be some assumed step in
the above description that I do not know about.
Note I also have Microsoft Visual Studio Community 2019 and 2022 installed but MinGW can't
find the MS c compilers either. I ran functions haveacompiler() and findmsvccompiler() but
both returned negative results ("F" and "unknown" respectively).

Did you have the MinGW toolbox running on your computer before ? There have been no other
changes in the toolbox than the new download link for gcc, since 8.3.0 is not available

MinGW toolbox purpose is not to detect MS compilers. I presume that VS 2022 won't be
detected by Scilab either (although VS 2019 will). However you can have both MS Visual
Studio and MinGW Toolbox, so the problem is not here.

If you want to use MinGW, I suggest that you suppress the mingwlib_x64 folder in your
SCIHOME directory (launch Scilab and type "SCIHOME" to see the actual path), then
Scilab. At restart please don't interrupt the libraries build process (it can be quite
long, typically one minute or more).
This is my first encounter with Scilab. I have never been able to get MinGW toolbox
(neither 8.3.0 nor 9.2.0) to work for me.
I found SCIHOME and deleted the subdirctory mingwlib_64, restarted Scilab but no change in
I removed MinGW toolbox, restarted Scilab, re-installed MinGW Toolbox, restarted Scilab,
no change, again.
Question. If the Scilab Mingw start up message includes "WARNING: MinGW Compiler not
detected.", how is the toolbox guided to a suitable compiler? I cannot find anything
Help that could possibly set things up so MinGW Toolbox can find gcc, and
findmsvccompiler() returns "unknown" (although I think my Visual Studio mscv
Note: I am a Windows User, with minimal expertise in the way it works behind the scenes,
although I began in the days of Winows93, and did once do an introductory course in Unix
(long since forgoten).
If you already have VS studio you don't need MinGW toolbox. This toolbox is dedicated to
users who don't have VS. Moreover VS Community 2022 won't be detected by Scilab and that
explains why findmsvccompiler() yields "unknown". The most recent version that
detected is VS 2019. So please uninstall VS 2022, reboot you machine, and
findmsvccompiler() will yield something. Then, all dynamic link examples should run fine,
e.g. you should test those in the ilib_build help page.
All good. Removed all VS installations, unistalled Scilab and rebooted.
Installed VS2019 and Scilab from fresh downloads.
findmsvccompiler() returned "msvc142express"
Ran simple electrical circuit in xcos, and it worked.
I think I went off track in the tutorial "Xcos for very beginners" (Scilab 2013)
on Page 14,
"Install a C compiler", where it advised that a C compiler may be necessary (if
loaded on the system) and it launched staight into "Install MinGW module ..." in
Windows". Maybe the final pargaph on p15 needs to be included in the introductory
(because I freely admit that I didn't reed past the Windows section because it related to
OS's of no interest to me. Australians, apparently, have the reputation of not reading all
the instructions, thoroughly, before starting the engine!).
