Problem to Compile concurrent.jar

[mreczio]

Hello
I can't Compile the concurrent.jar
I have download the concurrent source-code an when i compile i get only many errors and no a jar file.
How can i download a compiled version of concurrent.jar or how i must compile the source-file?

Sorry for my bad english

Can you please tell how you did that?

If you have a look at the sources, you can see that the "concurrent" sources are in the "" package.
Please create a directory tree with this command

  
mkdir -p src/EDU/oswege/cs/dl/util/concurrent
mkdir bin

and compile with this command

cd src
javac -d bin EDU/oswege/cs/dl/util/concurrent/*java

after that, create the jar file with this command.

jar cvf ../concurrent.jar .

Hope that helps.

Now i have create sie Directory /opt/src/EDU/oswege/cs/dl/util/concurrent/
and /opt/bin.
Then untar the conrurrent.tar.gz to /opt/src/EDU/oswege/cs/dl/util/concurrent/

cd /opt/src
javac -d bin EDU/oswege/cs/dl/util/concurrent/*java

and the output of this command is:

Those are only warnings, you can safely ignore. Just build the jar like neo proposed after compiling and you should do fine.

sorry, to stupid

Hi there,

I have to fresh up the thread again, because I have the same problem.

After the download i did the following:
- cd installtemps
- tar zxf concurrent.tar.gz
- cd concurrent
- mkdir bin
- javac -d bin *.java
here i got the same 2 warnings like mreczio (but ignored it )

- jar cvf ../concurrent.jar
but now i get the following message

ich:/installtemps/concurrent# jar cvf ../concurrent.jar
Flag 'c' erfordert die Angabe von Eingabedateien!
Syntax: jar {ctxu}[vfm0Mi] [JAR-Datei] [Manifest-Datei] [-C dir] Dateien ...
Optionen:
    -c  neues Archiv erstellen
    -t  Inhaltsverzeichnis für Archiv auflisten
    -x  benannte (oder alle) Dateien aus dem Archiv extrahieren
    -u  vorhandenes Archiv aktualisieren
    -v  ausführliche Ausgabe für Standardausgabe generieren
    -f  Namen der Archivdatei angeben
    -m  Manifestinformationen aus angegebener Manifest-Datei einbeziehen
    -0  nur speichern; keine ZIP-Komprimierung verwenden
    -M  keine Manifest-Datei für die Einträge erstellen
    -i  Indexinformationen für die angegebenen JAR-Dateien generieren
    -C  ins angegebene Verzeichnis wechseln und folgende Datei einbeziehen
Falls eine Datei ein Verzeichnis ist, wird sie rekursiv verarbeitet.
Der Name der Manifest-Datei und der Name der Archivdatei müssen
in der gleichen Reihenfolge wie die Flags 'm' und 'f' angegeben werden.

Beispiel 1: Archivieren von zwei Klassendateien in einem Archiv mit dem Namen classes.jar:
       jar cvf classes.jar Foo.class Bar.class
Beispiel 2: Verwenden der vorhandenen Manifest-Datei 'meinmanifest' und Archivieren aller
           Dateien im Verzeichnis foo/ in 'classes.jar':
       jar cvfm classes.jar meinmanifest -C foo/ .

so do i have to give the command
jar cvf ../concurrent.jar *.class
?? Or what does it mean?

Thanks,
Jordan
