[jnc-users] Undefined reference :: Log4j

[chosen f. <cho...@ya...>]

Hi, 

I'm trying to create a simple program that uses log4j. Unfortunately, I can't seem to make it work. I've used 2 methods in creating the EXE: 

A. Using the JNC UI:
   1.  In Step 1, I indicated my the .java file of my program (in Files), the directory of my program (in Directories), and the log4j jar located in my program's directory (in Archives).
   2. In Step 2, I set the main class by selecting my (only) java file. I only checked the Windows checkbox, and left everything else blank. 
   3. In Step 3, the only thing I enabled is the Show used commands checkbox.
   4. When I try to compile my project (Step 4) I get an error : 

      org/apache/log4j/jmx/Agent.java: In class 'org.apache.log4j.jmx.Agent':
    org/apache/log4j/jmx/Agent.java: In method 'org.apache.log4j.jmx.Agent.start()':
    org/apache/log4j/jmx/Agent.java:0: error: cannot find file for class com.sun.jdmk.comm.HtmlAdaptorServer
    org/apache/log4j/jmx/Agent.java:0: confused by earlier errors, bailing out


      while  it's  "processing log4j-1.2.13.jar". It seems that no .o file for my program was generated since it hasn't processed my program yet.

B. Using the command line
   1. I tried compiling my .java file using the command:
       gcj -c -g --classpath=C:\logtest\log4j-1.2.13.jar LogTest.java -o LogTest.o
      and it generated a LogTest.o file.
   2. Then I tried to build the EXE using the command: 
       gcj --main=test.gcj.LogTest -fjni -Llibs/win -Ilibs/win/gui/gui.jar -o C:\logtest\LogTest.exe -s -O2 -ljncNoGui -ljncNoJce -ljncTrial -IC:\logtest LogTest.
      and it shows an error : 
   LogTest.o: In function `ZN4test3gcj7LogTest18__U3c_clinit(unsigned e_E, __complex void, void)':C:/logtest/test/gcj/LogTest.java:8: undefined reference to `org::a
ache::log4j::Logger* org::apache::log4j::Logger::getLogger(java::lang::String*)'
:C:/logtest/test/gcj/LogTest.java:8: undefined reference to `org::apache::log4j::Logger::class$'
collect2: ld returned 1 exit status

Now I'm stuck... Help would be much appreciated...

Try using "-findirect-dispatch" as custom GCJ flag in the GUI.

Don't work with the command line version unless you know exactly what 
you're doing. You'll be well off using the GUI.
