Installation issue of EGSnrc on windows 11

[Fayzan1]

Hello, hope you all are fine. I am totally new to the EGSnrc and wanted to learn the MC simulation for radiation trasnport but it seems the installation of the EGSnrc is quite challenging.

I am trying to install the EGSnrc according to instructions and some videos on YouTube but failed to install it "EGSnrc-configure-windows".

Please help me out with some simple solutions.

This I have as compiler
"C:\Users>g++ --version

The Tclsh installed is
"% puts $tcl_version

The error is appearing in "EGSnrc-configure-windows"

Could load_vculib.c be compiled? .......................... no

Failed to compile egs_c_utils.c. This may be due to a variety of reasons
(e.g. non-standard include files, unsupported file lock operations, etc.
Will disable now the availability of a C compiler.
If you want to try to make the new parallel processing implementation in
cavrznrc and dosrznrc work,

1. Go to $machine_mortran_dir
2. Edit egs_c_utils.h and egs_c_utils.c to make them compile with your
   C compiler
3. Put
   REPLACE {$HAVE_C_COMPILER(#);} WITH {{EMIT;{P1}define HAVE_C_COMPILER};}
   in machine.macros
4. Put
   $HAVE_C_COMPILER(#);
   near the beginning of your user code.
5. If your compiler requires some unusual options, include directives, etc.,
   change the variable C_FLAGS in the spec file $conf_file in the
   $HEN_HOUSE/specs/ directory.

**** Failed to compile load_beamlib.c!!! ****
This is the tool for loading BEAM as a particle source for other user codes.

This is required to compile DOSXYZnrc!

This is due to the space in your path "Fayzan Ahmed". Please install EGSnrc in a path with no spaces, and as short as possible. E.g. C:\EGSnrc is ideal.

[Fayzan1]

Thank you very much, sir; it worked.

Please help me out about it as well.

I have opened every shortcut, and they are opening. But there is another shortcut, "MinGW Installer", which is not available; its file is not there in the directory "C:\MinGW\libexec\mingw-get\guimain.exe".
However, I have checked that CMD is showing the compiler.

Sorry, I don't understand your question. Why are you interested in guimain.exe? Is this related to an error during the installation of EGSnrc? If so, please share the installation log.

[Fayzan1]

Sir, please have a look at the image; these packages are installed.

Sir, its shortcut has appeared after the installation. So, I wanted to know whether this is required to install. If so, how do you install it? And is there any other package that needs to be installed? Thanks

[rtownson]

You're asking whether you need to run MinGW Installer because there is a shortcut for it on your desktop? It looks like you have already installed MinGW and EGSnrc, so no you don't need use the MinGW shortcut. If EGSnrc installed without errors (see the log in HEN_HOUSE/log to check for errors), then you're done. Test out the installation by doing the Getting Started manual, found here: https://nrc-cnrc.github.io/EGSnrc/
