IDAPython comes in two flavors:
|
|
|
|
* IDAPython-for-Python2.7
|
|
* IDAPython-for-Python3.x
|
|
|
|
# Switching between IDAPython-for-Python2.7, and IDAPython-for-Python3.x.
|
|
|
|
IDA ships with two versions of IDAPython:
|
|
* one that runs using the Python2.7 runtime
|
|
* one that runs using the Python3.x runtime
|
|
|
|
By default, IDA will load the one that runs using the Python3.x runtime.
|
|
In order to have IDA use IDAPython-on-Python2.7, the file
|
|
'use_python2' needs to be present in the 'python' subdirectory.
|
|
|
|
That file will be looked for in the following places:
|
|
* IDA's install path: path/to/ida_install/python/use_python2
|
|
* The 'IDAUSR' directory:
|
|
+ ~/.idapro/python/use_python2 (on Linux/OSX)
|
|
+ %APPDATA%\Hex-Rays\IDA Pro\python\use_python2 (on Windows)
|
|
+ [...or any other directory if the environment variable $IDAUSR is set]
|
|
|
|
# Selecting which Python3.x install runtime to use
|
|
|
|
The situation for IDAPython-for-Python2.7 is simple: it uses Python 2.7,
|
|
and will expect that [lib]python2.7.[dll|so|dylib] is present in the system
|
|
library path so that IDA can find it.
|
|
|
|
But when it comes to IDAPython-for-Python3.x, things gets more complex:
|
|
because different users might have different (and possibly multiple)
|
|
versions of Python3.x installed, IDA comes with a tool called `idapyswitch`
|
|
that can be run to select the desired Python3.x runtime.
|
|
|
|
If you selected IDAPython-for-Python3.x at the installation time,
|
|
the `idapyswitch` utility should already have been run and selected
|
|
the most appropriate Python3.x version.
|
|
|
|
Should you want to switch to another Python3.x install after installation,
|
|
please run `idapyswitch` from the IDA directory. It will scan for Python
|
|
installs present in the system's standard locations and offer you to choose one.
|
|
It also supports optional command-line switches to handle non-standard installs.
|
|
Run `idapyswitch -h` to see them.
|
|
|
|
On Windows, you may need to run it as administrator
|
|
so it can patch sip.pyd (library required for PyQt bindings).
