Subject: [devel] Java -> native code
Date: Fri, 23 May 2008 10:41:35 +0400
Message-ID: <200805231041.35920.ivanov@cg.ru> (raw)

Пытаюсь скоипилировать Java программу в нативный код.
Компиляю как сказано в в вики gcc следующим скриптом:

==============
#!/bin/sh
# ${1} is the name of a GCJ database file
gcj-dbtool -n ${1}

for JAR_FILE in `find -iname "*.jar"`
do
        echo "Compiling ${JAR_FILE} to native"
        gcj -shared -findirect-dispatch -Wl,-Bsymbolic -fjni -fPIC 
${JAR_FILE} -o ${JAR_FILE}.so
        gcj-dbtool -a ${1} ${JAR_FILE} ${JAR_FILE}.so
done
=========================

После этого запускаю при помощи gij:

====================
cd /home/999/devel/cgapp
LIB=.

gij -verbose:class -cp ${LIB}/01_JFUModule.jar:\
${LIB}/zags.jar:\
${LIB}/classes12.jar:\
${LIB}/jbcl.jar:\
${LIB}/jboss-j2ee.jar:\
${LIB}/JfuClientServer.jar:\
${LIB}/jtds-0.9-rc1.jar:\
${LIB}/log4j-1.2.14.jar:\
${LIB}/xerces.jar:\
${LIB}/ibdmodels.jar:\
${LIB}/ibdClientServer.jar:\
${LIB}/jooreports-2.0.0.jar \
-Dgnu.gcj.precompiled.db.path=./zgapp.db \
-Djava.library.path=. \
cg.framework.client.Jframework
========================

В выводе повсеместно вижу такие строки:

[Loaded (BC-compiled) org.apache.log4j.MDC from 
(file:/home/999/devel/cgapp/log4j-1.2.14.jar <no certificates>)]
[Loaded (BC-compiled) cg.framework.utils.config.EConfigurator from 
(file:/home/999/devel/cgapp/01_JFUModule.jar <no certificates>)]

Как я понимаю мои .so файлы никак тут не используются, а берется просто байт 
код из jar файлов.
