[kotlin-kmp] Enums only files skipped when multiple schemas are used as input

[DadiBit]

• Language: kotlin-kmp (kotlin/jvm & swift do not face this issue, probably just a kmp thing)
• Compiler: gcc 13.2
• OS: Ubuntu 23.10
• Flatc: master, commit 129ef42]

I have multiple fbs source files. Some of these have tables, some others have enums, which are included and used in those tables.
When I run flatc --kotlin-kmp schema/*.fbs I see that MyEnum.kt is always "empty": the file doesn't have any enum, just the "head":

// automatically generated by the FlatBuffers compiler, do not modify

package com.openmeteo.flatbuffers.forecast

import com.google.flatbuffers.kotlin.*
import kotlin.jvm.JvmInline

But (!), when I run flatc --kotlin-kmp schema/model.fbs everything is fixed.

"Actually, you could just run a loop as workaround" - strangely, looping over each single file doesn't fix the issue: I suspect there's some async/caching stuff not getting properly set/cleaned-up, or at the very least something time-related.

Can anyone else replicate the issue with the latest repo source code?

If needed, I can share my fbs files.

My finds so far:

• Perhaps fix: kotlin-kmp start/end method names don't match #8147 could be related, idk

• I'm trying to find a fix in

  flatbuffers/src/idl_gen_kotlin_kmp.cpp

  Line 98 in 129ef42

  *enum_def.defined_namespace, enumWriter.ToString(), true))

Kind regards 😄

Found a workaround:
Comment out the if (enum_def.generated) return; check at L383:

flatbuffers/src/idl_gen_kotlin_kmp.cpp

Lines 380 to 381 in 129ef42

	void GenEnum(EnumDef &enum_def, CodeWriter &writer) const {
	if (enum_def.generated) return;
