Re: problem using gen-class and using the class name in the same file
It seems that only the constructor is the problem. it there is workaround to solve this ? I have several gen-class calls each need a constructor with an instance of the same class as parameter.

Re: problem using gen-class and using the class name in the same file
Yes exactly, i need a constructor which require an instance of the same
class as parameter and i need to create new instances of this class in some
methods (i implement an abstract class that require this).

problem using gen-class and using the class name in the same file
Hi
I try to compile a file that generate a class with gen-class that include
class name
at different places in the file here is a simplified version of the
problem:
lein init test-gen
then edit the core.clj with
--
(ns test-gen.core
(:gen-class
:name test-gen.Tata
:init pre-init
:constructors {
[Integer] [Integer]
[test-gen.Tata] [Integer]
}
)
)
(defn -pre-init
[x]
(test-gen.Tata. 9)
9)
--
add ":aot [test-gen.core]" in project.clj
then compile with lein compile:
Compiling test-gen.core
Exception in thread "main" java.lang.ClassNotFoundException: test-gen.Tata,

Compilation failed: Subprocess failed
The problem seems to be that i am using a class that doesn't exist yet.
If i comment all lines referring to test-gen.Tata; compile; uncommment
those lines; compile; again then it works.
Is there a way a better to co
