Hi

I'm porting my linux based game to Windows - and everything is compiling ok except for these three lines

1>Finished searching libraries
1>as_callfunc_x64_msvc.obj : error LNK2019: unresolved external symbol CallX64 referenced in function "unsigned __int64 __cdecl CallSystemFunctionNative(class asCContext *,class asCScriptFunction *,void *,unsigned long *,void *,unsigned __int64 &)" (?CallSystemFunctionNative@@YA_KPEAVasCContext@@PEAVasCScriptFunction@@PEAXPEAK2AEA_K@Z)

I assume this means that I'm not linking a particular windows library in - but I really have no idea on how to start looking for what it might be.

Any suggestions?

Thanks

EDIT**

Ok - found I was missing as_callfunc_x64_msvc_asm.asm - which defines those three functions. Now - to figure out how to compile this - I have the custom build command from the help page

ml64.exe /c  /nologo /Fo$(OutDir)\as_callfunc_x64_msvc_asm.obj /W3 /Zi /Ta $(InputDir)\$(InputFileName)

How do I run this as a custom build on this one file?

Add the .asm file to your project, right click on the file in the solution explorer view, find the place about 'Custom Tool'. Add the necessary details to invoke your line with m164.exe and its command line arguments

You should be able to open the MSVC2015 project in MSVC2017, and let Visual Studio do the necessary changes to the project files. That way you won't need to try to figure it out on your own.
