Thank you for the description. Your instructions are exactly the ones I use, as well. They work great. I have tested both 32-bit and 64-bit builds in the past. Like you, I only use 64-bit now. What I was trying to determine is whether the msvc Makefile and infrastructure would support the C++ language, rather than just C. For autoconf-based platforms there is a --with-cxx option to enable this behavior. But I saw nothing in the msvc directory to provide the same capability. According to Marius and Daniel, it may not be too difficult to implement, but it does not exist today.

It works well in Windows.


Run x64 Native Tools Command Prompt for VS 2022

cd to $ECL/msvc

In Makefile enable line ECL_WIN64 = 1, it turns on Windows 64 build.

Then run nmake and nmake install. Last command creates Windows ECL distribution.


ECL is compiled successfully on my side.


I did not test other VS version, but it should work as well. Also, I only tried win64 builds, have no idea if it will work with other configurations, drop a note if you’ll do that.

Hey Dave,

technically there shouldn't be any issue with the compilation. That
said *I think* that cl.exe picks the compiler mode based on the file
extension, and as you will see in msvc/c/Makefile, dpp compiles .d files to .c.

ECL (as the source code) can run with C++ core and C++ compilers but for Windows appropriate Makefile *doesn't seem* to cater to that.
