在Ubuntu上编译Tuxedo Client时遇到undefined reference to `dlopen'等错误。问题源于Ubuntu对共享库链接方式的改变，不兼容其他发行版。为解决此问题，可以尝试在buildclient命令中添加链接器选项`--no-as-needed`，例如：`buildclient -o simpcl -f "-Xlinker --no-as-needed simpcl.c"`。虽然不推荐，但该方法可以缓解编译错误。

This problem is caused because Ubuntu is not a supported platform and Oneric has made some substantial changes to how shared libraries must be linked, and this change is not backward compatible with other distributions such as RedHat and its derivatives. Although not recommended, you should be able to fix this by adding the linker option --no-as-needed. To do this with buildclient, you would use a command like:

buildclient -o simpcl -f "-Xlinker --no-as-needed simpcl.c"
