Hello, Recently I used SQLite in Java, so I download the [sqlite-jdbc](https://github.com/xerial/sqlite-jdbc). In this project, there is the following paragraph： > Since sqlite-jdbc-3.6.19, the natively compiled SQLite engines will be used for the following operating systems: > * Windows XP, Vista (Windows, x86 architecture, x86_64) > * Mac OS X 10.4 (Tiger), 10.5(Leopard), 10.6 SnowLeopard (for i386, x86_64, Intel CPU machines) > * Linux i386 (Intel), amd64 (64-bit X86 Intel processor) This means that the native SQLite they are using is compiled from the official version, something like: > libsqlitejdbc.so sqlitejdbc.dll I want to know how did they compile the source code so that I can modify some SQLite source code and apply it to sqlite-jdbc according to my need.
