This instance uses Python's ctypes and requires a single
|
|
|
- .dylib linking together LTC and one or more math libraries.
|
|
|
- Building a single .dylib is needed because LTC wants a
|
|
|
- fairly tight relationship between itself and the mathlib.

- (ctypes can load multiple .dylibs, but it does not support
|
|

- this level of coupling between those independent libraries.)

My .dylib was created on OSX with the following steps:
|
|
|
|
|
|
1- compile LTC to a .a static lib:
|
|
|
- CFLAGS="-DLTM_DESC -DUSE_LTM -DTFM_DESC -DUSE_TFM \
|
|
|
- -I/usr/local/include" make
|
|
|
+ CFLAGS="-DLTM_DESC -DUSE_LTM" make
|
|
|
|
|
|
- 2- link LTC, LTM and TFM into a single .dylib:
|
|
|
- ar2dylib_with_and tomcrypt tommath tfm
|
|
|
- where ar2dylib_with_and is a shell script that combines
|
|
|
- the .a with .dylibs for LTM and TFM
|
|
|
+ 2- link LTC and LTM into a single .dylib:
|
|
|
+ ar2dylib_with tomcrypt tommath
|
|
|
+ where ar2dylib_with is a shell script that combines
|
|
|
+ the LTC .a with the LTM .dylib
|
|
|
|
|
|
Reminder: you don't need to bind in a math library unless
|
|
|
you are going to use LTC functions that depend
|
|
|
on a mathlib. For example, public key crypto
|
|
|
needs a mathlib; hashing and symmetric encryption
|
|
|
- does not.
|
|
|
+ do not.
|
|
|
+
|
|
|
+ This code was written for Python 2.7.
