Here are the changes that I have made to port Crypto++ 3.0 to the Mac:

Compiler: 		Metrowerks CodeWarrior Pro 4.1 (4 + netborne patches)
Processor:	PPC
(note that the Metrowerks 68K compiler cannot yet build crypto++)

File:	config.h
Comment out line 6
// #define IS_LITTLE_ENDIAN

File:	dsa.h
add
#include	<climits>
after line 3

File:	Integer.h
Move lines 91-97 (definitions of Power2, One, and Zero) to before line 79
(before the last constructor, the one that has Zero as a default argument)

File:	luc.h
add
#include	<climits>
after line 3

File:	nr.h
add
#include	<climits>
after line 3 

File:	Rabin.cpp
Comment out line 14 (to eliminate duplicate linker warnings)
// template class OAEP<SHA>;

File:	RSA.cpp
Comment out line 15 (to eliminate duplicate linker warnings)
// template class OAEP<SHA>;

File:	misc.h
replace templated functions rotl and rotr with ones that work:
(replace lines 29 thru 37 in original)

template <class T> inline T rotl(T x, unsigned int y)
{
 	unsigned int z = y % ( sizeof(T) * 8 );
	return ((x<<z) | (x>>(sizeof(T)*8-z)));
}

template <class T> inline T rotr(T x, unsigned int y)
{
 	unsigned int z = y % ( sizeof(T) * 8 );
	return ((x>>z) | (x<<(sizeof(T)*8-z)));
}

With these changes, Crypto++ 3.0 compiles, links, and passes all validation tests.
Thanks to Daniel Steffen for his help, and to Wei Dai for writing Crypto++.

------------------

A few more changes may be necessary.

Daniel A. Steffen:

Add the line
#include "pubkey.cpp"
at the start of "validat2.cpp" and "bench.cpp"
to get 'MaxPlainTextLength' etc instantiated.

Eric C Wagner:

That fixed the problem. Another addition to the porting notes should be
to add #include <console.h> to the test.cpp includes and put the line
argc = ccommand(&argv);
at the beginning of the try block in the main function.
