Error: No compiler is available.
o que eu faço?isso quer dizer que não compilou?
Por Favor Prof. Marcelo,
Também estou com o mesmo problema do Marcel, mas não sei qual arquivo preciso colocar em tools.jar e onde encontrá-la após a instalação da linguagem java.
O DrJava imprimiu:
1 error found:
File: (no associated file) [line: (no source location)]
Error: java.lang.NoSuchMethodError: com.sun.tools.javac.util.Options.put(Ljava/lang/String;Ljava/lang/String;)V
Está tudo instalado, obedecendo todos os passos.
Estou usando:
jdk-1_5_0_15-windows-i586-p
drjava-stable-20080106-0744 (2)
Grato.
Ocorre quando tento compilar o programa.
"Talvez haja um problema de versão. Se você já tinha uma JRE (Java Runtime Enviroment) instalada, você precisa certificar-se de que a versão é a mesma que a do JDK."
Desculpe, não sei como certifico-me da versão. E se realmente houver, como arrumá-la.
Grato.
Seria esse?
