Hi,

is there a how to or wiki page, how to use LDC in combination 
with "Visual C++ Build Tools 2015".
It seems the build tools are the easiest way to get the microsoft 
build tools (linker) without installing a full IDE.

I don't know whether any of the devs using Windows got a chance to test 
the Build Tools on a system that doesn't have the full IDE installed, 
but in theory it should work just fine. As for building LDC itself, 
CMake should automatically detect their presence if I remember 
correctly, so everything should work out of the box.

For using them together with a binary LDC release, the question is 
whether we detect it correctly in executeMsvcToolAndWait() 
(driver/linker.cpp). I assume the build tools also come with a link to 
the script that sets up the environment variables for use with the C++ 
toolchain? Launching LDC from that should definitely work.

It would be great if you could give it a try and share your experiences 
on the wiki afterwards (if everything works nicely, it should just be a 
short note). As you mentioned, we should really document this well to 
make using LDC a seamless experience (and possibly even automatically 
download the tools from a to-be-written LDC installer).

Best,
David

Hi David,

some findings so far:

-> Whether C++ Build Tools are installed could be checked by 
regedit value:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualCppBuildTools\14.0
Installed = 1

As far as I understand, the product path seems to be located here:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\14.0\Setup\VC
ProductDir = C:\Program Files (x86)\Microsoft Visual Studio 
14.0\VC\

The existing batch script C:\D\ldc2\bin\msvcEnv.bat needs to 
extract this information from the windows registry and write the 
product path without the ending "VC\" into environment
variable LDC_VSDIR
=> In the last line of the batch "VC\" is concatenated to the 
environment variable

ldc2 will find the linker, if I set the environment variable like 
this
SET LDC_VSDIR=C:\Program Files (x86)\Microsoft Visual Studio 14.0\

Kind regards
André
