#pragma load(<libraryname>.dll) in Windows Subsystem for Linux

[Francois Wessels]

I am using xeus-cling on Windows Subsystem for Linux, which is currently the most popular/best known alternative to the no-windows-support-related "problem".

I often use the magic %%file to write .cpp scripts to a Windows directory as follows ...

%%file /mnt/c/Users//path/to/project/.cpp
/*
cpp code here
*/

I sometimes compile files using the following syntax in a code cell ...

! powershell.exe g++ C:\Users\\path\to\project\.cpp -o C:\Users\\path\to\project\.exe

It is also possible for me to create .dll and .dir files using a similar command as the above with the -shared flag.

The problem that I experience is to import .dll and .dir using the #pragma directive like so ...

#pragma cling add_include_path("/mnt/c/Users//path/to/project/") // no error
#pragma cling add_library_path("/mnt/c/Users//path/to/project/") // no error

I have also tried it like this ...

#pragma cling add_include_path("C:\Users\\path\to\project\") // no error
#pragma cling add_library_path("C:\Users\\path\to\project\") // no error

which does not really seem what's causing the problem.

However, running the below in a code cell ...

#pragma cling load(".dll")

gives this error ...

input_line_147:1:29: error: expected .dll to be a library, but it is not. If this is a source file, use #include "<libraryname>.dll"
#pragma cling load(".dll")
^ (This little up-arrow should be pointing to the closing parenthesis)
Interpreter Error:

Is there a fix for this or does anyone have an idea of how to work around this, or will this just be classified as a no-windows-support-related error?
