If you plan to write a lot of WASM in Go, you might want to consider compiling with TinyGo, which is a Go compiler for embedded and WASM.

TinyGo supports a //export or alias //go:export comment directive that does what you're looking for.

I'm copy-pasting the very first example from TinyGo WASM docs:

Why is it not 12 (4 + 8)? Does Rust have special treatment for tuples?

No. A regular struct can (and does) have the same "problem".

The answer is padding: on a 64-bit system, an f64 should be aligned to 8 bytes (that is, its starting address should be a multiple of 8). A structure normally has the alignment of its most constraining (largest-aligned) member, so the tuple has an alignment of 8.

This means your tuple must start at an address that's a multiple of 8, so the i32 starts at a multiple of 8, ends on a multiple of 4 (as it's 4 bytes), and the compiler adds 4 bytes of padding so the f64 is properly aligned:

TL;DR. You should check that the pointer returned by bpf_map_lookup_elem is not NULL.

With the following logs, the BPF verifier is telling you that, when it reaches the dereference of my_pid, the pointer may still have a NULL value. It thus contains a map value or a NULL value, i.e., map_value_or_null.

We needed the adress of t0

Registers don't have addresses: they have names; they have positions/index in the register file, and, they hold values.

Only memory has addresses.

Since, lw, does need the correct value of mem[$t0] + 4

That lw accesses mem[$t0+4], and it needs $t0's value so it can do the + .

The lw and sw instructions compute an effective address:

From DataSource Configuration in the docs:

Spring Boot can deduce the JDBC driver class for most databases from the URL. If you need to specify a specific class, you can use the spring.datasource.driver-class-name property.

So start without configuring anything and just putting the JDBC driver on the classpath. If it would not work, you can manually configure it.

If you want to stop the music, when the installer is closing, just use the same code you already have in StopButtonClick from DeinitializeSetup:

You need to add this to the app config:

Is it possible to do this?

Yes: add -u main to your link line.

To understand what's wrong with your command line, read this or this.

You've used -Xms to force the JVM to get ~30GB at JVM startup.

It has tried, and failed. It only obtained 8GB. It needs another 22-ish GB but cannot get it. That is what the error message is telling you. This is consistent with a dump that says the heap is only 8GB.

You're asking for more than the OS will provide. You'll need to figure out what's going on in the OS in general.

Your application code is probably not involved. The JVM is still initializing its heap in accordance with your command-line options.
