Thanks for the quick fix with the debug mode problem! I ran into another issue when trying to update my actual games to the newest cerberus. One of my libraries bulk-imports brl and it fails with a bunch of "unresolved external symbol" errors that I don't know what to do with.

I can trigger it by adding Import brl or Import brl.httprequest to the top of the bouncyaliens example.

Mmh, so the 2019 version worked? I have to check that.

Edit: V2019-10-13 didn't work, V2019-05-05 does also not work. Let's look into this...

Edit2: Had to correct myself. @wick, did it ever work for you in MSVC? If yes, which version of CX and MSVC?

What is MSVC // how do I check its version?

Importing brl for the bouncyaliens test works for me on Cerberus version v2018-04-21.
 
I was now able to build static libs of Curl for VS2017. Next week i will try that i can make it work with it.
 
Thank you for taking it on! I really appreciate it.
 
Hi @wick if you have time... please copy the content of the zip file into your targets/glfw3/template folder. Please backup the curl and msvc folder.
I compiles now and runs. What puzzles me atm is that in debug mode, the httprequest.cxs example retrieves nothing, in release mode it works fine. On MingW both modes work fine.

Excellent, it also compiles for me. I'll test if my http requests still work.

Is there somewhere I can read up on the differences between minGW and MSVC and such? I've never been quite clear on what they're all doing besides vague "C++ compiling magic". I also don't know how cerberus interacts with them or how to direct it to do so.
