steps:

1. open VS2015 x86 Native Tools Command Prompt
2. follow instructions in https://github.com/ruby/ruby/blob/trunk/win32/README.win32

most of the compilation completes including producing .lib files, but nmake finally errors out at this stage and the whole process doesn't complete:

Trying other configure options such as --with-static-linked-extension cause different errors such as NMAKE : fatal error U1073: don't know how to make 'enc/libenc.lib'.

When I link to the static lib produced in a C++ project, I get many linking errors:

Just for curiosity, ruby 2.4.x works for you on windows if you compile it?

Hi, exactly the same errors for ruby_2_4 branch.

My goal is to link to the produced static library, so I supposed I need to ideally get --with-static-linked-extension working. Otherwise, is there a list of external lib dependencies I should be linking to before the ruby lib? So far I have only been able to guess at ws2_32.lib, but the maths stuff worries me since that should be build into MSVC compilers.

I got both versions to build easily with an old VS2010 command prompt, but I still get the imp errors when I link to the static library. Am I missing some kind of configuration outside of --with-static-linked-extension?

EDIT: Seems I can compile everything if I run the command prompts with Administrator privileges. That solves most of my problem here. Anyone know about linking to the produced libraries?
If I link with vcruntime140-ruby250-static.lib then I get 121 undefined symbols like those listed above.
If I link to vcruntime140-ruby250.lib then I get just these two:
LNK2005 _getenv already defined in vcruntime140-ruby240.lib(vcruntime140-ruby240.dll) Engine.App C:\Repositories\ags\Solutions\Engine.App\libucrtd.lib(getenv.obj)
LNK2005 _fclose already defined in vcruntime140-ruby240.lib(vcruntime140-ruby240.dll) Engine.App C:\Repositories\ags\Solutions\Engine.App\libucrtd.lib(fclose.obj)

After some more investigation I have discovered that ruby is being compiled with /MD, how can I build it with /MT instead? Since the rest of my app is using /MT I suspect that mismatch is causing me issues. Sometimes I have got the library to link in my target app, but I get weird issues related to passing file pointers around the CRT boundaries, and would like to make ruby match all the other libs I am linking against.

I'm not that familiar with MS build tools, but I think ruby is building with this file - appveyor.yml, which I believe is using 140. Test results here.

test-all failure may be due to conflicting OpenSSL versions, as the files exist both in the MSYS2/MinGW system and the OpenSSL-Win32 directory.

Do you know how to configure the project to build with /MTd? I am getting "unexpected ucrtbased.dll" when trying to link miniruby.exe

Sorry, I don't. I assume you've built other projects with /MTd? I'm not much of a C type...

just noticed from prev:

If I link to vcruntime140-ruby250.lib then I get just these two:
LNK2005 _getenv already defined in vcruntime140-ruby240.lib(vcruntime140-ruby240.dll) Engine.App C:\Repositories\ags\Solutions\Engine.App\libucrtd.lib(getenv.obj)
LNK2005 _fclose already defined in vcruntime140-ruby240.lib(vcruntime140-ruby240.dll) Engine.App C:\Repositories\ags\Solutions\Engine.App\libucrtd.lib(fclose.obj)

Maybe a typo, but both ruby250 and ruby240 are listed. It should be one or the other, but not both?

[rocifier (Ryan O'Connor)]

That was a typo, I've tried both 2.4 and 2.5 separately.

I'd also settle for rebuilding all the other libraries in the project to use /MD but I'd need to get /MDd building on Ruby. I tried overwriting the option by manually setting COMPILERFLAG = /MDd in the debug configured Makefile, which works until linking stage where I get

linking miniruby.exe
unexpected ucrtbased.dll
NMAKE : fatal error U1077: '.\miniruby.exe' : return code '0x1'
Stop.

EDIT: I'm not getting much assistance here and I'm making a little more progress trying to link with /MDd for debug configurations, but it's slow. I'm moving the conversation to here: https://stackoverflow.com/questions/46262403/embedding-ruby-in-vc-and-calling-ruby-setup-returns-tag-raise if anyone cares to join in and assist, I will buy you a beer

[rocifier (Ryan O'Connor)]

This patch helped me understand the problem above: https://bugs.ruby-lang.org/issues/12644
After pasting the ucrtbased.dll from StarCraft II support folder into my build folder, I can now fully build ruby with /MDd and link it. You may close this issue.
