Windows build issues

[4lph4-Ph4un]

Hi! Looking forward of getting to do some gamedev with Clojure :)

I'm trying to run both web versions and develop native one but in all of these cases something funky happens. And not the good kind of funky - the bad kind!

Output on native case:

D:\Projects\Lisps\Clojure\hello-world>powershell -command clj -A:dev:windows native
2019-08-12 00:12:01.003:INFO::main: Logging initialized @3523ms to org.eclipse.jetty.util.log.StdErrLog

Syntax error (OutOfMemoryError) compiling at (D:\Projects\Lisps\Clojure\hello-world\dev.clj:33:1).

Output on web case:

As it can be seen, on windows clj must be evoked with powershell (major bummer - I know). Don't know if that additional step contributes to the problem and I'm quite a n00b with Clojure-CLI (need to read up on it more).

Edit: Ensured that there's no issue because of using cmd.exe with preceding powershell -command. Initialized directly with powershell instead and used the commands stated in the docs. The results seem to be the same.

I actually develop on windows 10, I've never experienced this. How much ram do you have? Maybe try something like clj -J-Xmx1g -A:dev:windows native to make sure it has enough heap space, though it definitely should not need that much.

Ah, as a person who does anything game related on a windows I'm very happy to hear that. I have 32GB. Seems the heap space limit did the trick but it's definitely strange that it's needed..

Here's the full report that is generated when OutOfMemoryError happens. Has this something to do with Edna?

Ah that actually makes sense, maybe it's loading the entire sound bank into memory. I think you can find the max heap size for your java installation with this:

java -XX:+PrintFlagsFinal -version | findstr MaxHeapSize

Mine says 4253024256 so about 4 gigs I guess. At any rate, I'm sure other people will run into it so I added it to the template here. You might want to do the same so you don't have to keep typing it. If you're not planning on making music you can also remove the edna stuff from the project.

Actually it'd be better to add it here instead so it is used when doing dev and prod commands.

Nevermind, I don't think you can add :jvm-opts to the top level so my first link is better.

Ah, thanks for the help! :)
