Re: Compiling with mysql

1) ok, I used the option  -findirect-dispatch
2) I also updated gcj to 4.3
gcj --version
gcj (Ubuntu 4.3.1-8ubuntu1) 4.3.1

3) I generated in windows using 
Eclipse 
jdk1.5.0_16
mysql-connector-java-5.0.8-bin.jar

Then the jar file i compile in the ubuntu machine getting the following
error

gcj --main=SearchManager -o search Searcher.jar -findirect-dispatch
/tmp/cc5qITfH.o: In function `com::mysql::jdbc::Buffer*
com::mysql::jdbc::MysqlIO::reuseAndReadPacket(com::mysql::jdbc::Buffer*)':

Searcher.jar:(.text+0x3b4131): undefined reference to `.L53612'
