GCJ on POI

GCJ on POI

[HK Tan]

Hi I have been trying to get gcj to compile for the for poi.
This are the steps that was trying to follow
gcj -shared -classpath ../jakarta-poi/lib/commons-logging-1.1.jar
   -Lcommons-logging-1.1.jar.so
   ../jakarta-poi/build/dist/poi-3.2-alpha1-20080804.jar -o
   poi-3.2-alpha1-20080804.jar.so

   gcj --classpath=../jakarta-poi/build/dist/poi-3.2-alpha1-20080804.jar
   -c HW.java

   gcj --main=HW -Lpoi-3.2-alpha1-20080804.jar.so HW.o -o HW

But it bombs out on the step by
saying
org/apache/poi/dev/RecordGenerator.java: In class
`org.apache.poi.dev.RecordGenerator':
org/apache/poi/dev/RecordGenerator.java: In method
`org.apache.poi.dev.RecordGenerator.generateRecords(java.ljava.lang.String,java.lang.String,java.lang.String)':

errors, bailing out

I'd compile everything with -findirect-dispatch -Bsymbolic.

I found that the reason is due to the xml-apis.jar not included with gcj
gcj -shared -classpath xml-apis.jar -Lxml-apis.jar.so
poi-3.1-FINAL.jar -o poi-3.1-FINAL.jar.so  -findirect-dispatch
-Bsymbolic

My gcj is 3.4.5

But now I have another problem..
