use oracle JDK,not OpenJDK
1.
遇到错误Error:./gamma: relocation error: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/libjava.so: symbol JVM_FindClassFromCaller, version SUNWprivate_1.1 not defined in file libjvm.so with link time reference
修改文件：/home/westward/soft/openjdk-7u-40/openjdk/hotspot/make/linux/Makefile （yuandaima）
去掉文件中所有的test_gamma即可
2.
./gamma: relocation error: /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.36.x86_64/jre/lib/amd64/libjava.so: symbol JVM_FindClassFromCaller, version SUNWprivate_1.1 not defined in file libjvm.so with link time reference
通过vim `find . -name 'CurrencyData.properties'` 把里面的时间改在10年之内就可以了
