Ubuntu上跑GWT

1.下载



2.安装

没啥好安装的,直接解压就好了,我习惯放到/opt目录下边

gwt-linux-1.4.61.tar.bz2

然后创建一个指向这个目录的链接

ln -sv /opt/gwt-linux-1.4.61/ /opt/gwt

3.运行例子测试一下

cd /opt/gwt/samples/Hello

./Hello-shell

*** 应该会出错,提示如下

** Unable to load Mozilla for hosted mode **
java.lang.UnsatisfiedLinkError: /opt/gwt-linux-1.4.61/mozilla-1.7.12/libxpcom.so: libplds4.so: cannot open shared object file: No such file or directory

原因就是.so文件无法正常的加载,测试方法:

ldd /opt/gwt/mozilla-1.7.12/libxpcom.so
linux-gate.so.1 => (0xffffe000)
libplds4.so => /opt/gwt/mozilla-1.7.12/libplds4.so (0xb7eae000) ###这里应该是找不到的!!!
