以下將介紹如何在 64 位元 Linux 平台上正常啟動 32 位元的 Network Connect 連線軟體,本方法僅適用於 NC 版本為 7.3 以後。NC 7.3 以後的版本會透過 update-alternatives 程式,自動找尋合適的 32bit Java Runtime,如此將可以在 64bit 瀏覽器下正常啟動 NC 連線程式。
名稱 | 版本 |
---|---|
作業系統 | Fedora 18 (Linux 3.8.1-201.fc18.x86_64) |
Java Runtime | jre-7u17-linux-x64.rpm (x86_64) jre-7u17-linux-i586.tar.gz (i586) |
Network Connect | 7.3-3-Build23377 |
# sudo yum --nogpgcheck localinstall jre-7u17-linux-x64.rpm # update-alternatives --install /usr/lib64/mozilla/plugins/libjavaplugin.so \ libjavaplugin.so.x86_64 \ /usr/java/default/lib/amd64/libnpjp2.so \ 20 # update-alternatives --config libjavaplugin.so.x86_64 有 2 個程式提供「libjavaplugin.so.x86_64」。 選擇 指令 ----------------------------------------------- * 1 /usr/lib64/IcedTeaPlugin.so + 2 /usr/java/default/lib/amd64/libnpjp2.so 請輸入以保留目前的選擇[+],或輸入選擇號碼:2
# mkdir -p /opt/java32 # cd /opt/java32 # cp /tmp/jre-7u17-linux-i586.tar.gz . # tar xvfz jre-7u17-linux-i586.tar.gz # update-alternatives --install /usr/bin/java \ java \ /opt/java32/jre1.7.0_17/bin/java \ 20
java-1.5.0-gcj
或 libgcj
,如此將可能無法正確找到合適的 32bit Java Runtime,以致於無法正常啟動 NC,建議可暫時移除。詳細除錯資訊如下:Calling Super Init.
