Python中static相关知识小结


            非 static 编译

不指定额外参数直接编译 Python:





$ ./configure

$ make





查看所依赖的共享库:





$ ldd python

  linux-vdso.so.1 => (0x00007fffcd95a000)

static 编译

指定 static 相关参数编译 Python:





$ ./configure LDFLAGS="-static" --disable-shared

$ make LDFLAGS="-static" LINKFORSHARED=" "





发现有部分库未能被编译，编译结果中输出如下内容:

重新编译后能将部分 Modules 编译为 static 库，输出:

_curses     _curses_panel  _elementtree

_hashlib    _sqlite3    _ssl
