Is it possible to build this library under msys2's gcc?

[asmwarrior]

I looked at the cmakelist file, this file mainly are support the Microsoft visual studio c++, but not mingw gcc?

The engine is tested with several compilers, see the https://github.com/kovacsv/VisualScriptEngine/wiki/Building-the-Engine page for details.

I think it should work with mingw gcc, too. Just generate makefiles with cmake, and use the gcc compiler to build.

First, thanks for the reply.

But if you look at the CMakeLists.txt, I see some code snippet:

function (SetCompilerOptions module)
	target_compile_options (${module} PUBLIC "$<$<CONFIG:Debug>:-DDEBUG>")
	if (WIN32)
		set (AdditionalWarnings /w44061 /w44062 /w44265 /w44266 /w44355 /w44596 /w44800)
		target_compile_options (${module} PUBLIC /W4 /WX ${AdditionalWarnings} ${VSE_CUSTOM_BUILD_OPTIONS})
	else ()
		target_compile_options (${module} PUBLIC -std=c++11 -Wall -Wextra -Werror ${VSE_CUSTOM_BUILD_OPTIONS})
	endif ()
endfunction ()

This looks like under Windows, it has only support the visual studio C++ compiler options. /w like option is only for this compiler.

Thanks.

Yes, you are right, instead of WIN32, it should check visual studio. Have you tried to delete the WIN32 branch, and use the other one for mingw?

I'm not familiar with cmake, so I don't know how to tweak the cmakelist file.

BTW: What does the "visual script" used for, from the demo https://kovacsv.github.io/VisualScriptEngineWebDemo/ I see that it can do some simple calculation (show the parsing tree of the calculator)?

Thanks.

Please try to modify the function in the CMakeLists.txt file like this, and see if it works with mingw.

function (SetCompilerOptions module)
	target_compile_options (${module} PUBLIC "$<$<CONFIG:Debug>:-DDEBUG>")
	target_compile_options (${module} PUBLIC -std=c++11 -Wall -Wextra -Werror ${VSE_CUSTOM_BUILD_OPTIONS})
endfunction ()

Hi, I tried to fix codes. Eventually, it can generate executable files. However, when I opened it, it show me "Unable to locate program input point ZNKSt19_codecvt_utf8_baselwE10do_unshiftER9_MbstatetPcS3_RS3"

I think you need to use some dependency check tool to check which dll files are used by the exe. Maybe, wrong DLL file is used.

Thank you. After dependency check, I found that program missing libstdc++-6.lib. The program can run now.
