Are Static Library Machine Independent?

Well, I am Developing a program in C++ in an Ubuntu 10.04.1 (Intel Core2Quad) LTS, but the releases are running in a Debian 5.0.5 (Intel(R) Xeon(R) CPU). Some libraries such as crypto++ or mysqlclient have different versions in both OS. So I decided to compile the binary statically with all the libraries statically compiled in the Ubuntu and then upload the completed binary to the Debian.

I am not sure if this method is correct, because the static libs maybe are architecture-dependent and maybe can get in conflict in the Debia开发者_JAVA百科n Machine. If I want to use the new library version of Ubuntu in the Debian, should I compile them in the Debian?

Thanks in advance

They're architecture dependant. Usually though, library gets compiled to a common architecture on x86 machines, such as i686 which will run fine on both an Intel Xeon and a Intel Core2Quad (But not on e.g. an old Intel Pentium processor)

No, it is not machine independent. The only difference is that all libraries are bundled with the executable, so there is no risk for the program to fail on load with a "library not found" message. In summary, it will works for all linux distributions, but it will not work for Windows, for example.
