howto compile cryptopp 5.6.2 with mingw

Question

I am trying to build cryptopp 5.6.1 with mingw 4.8.1 (sjlj). I've changed GNUMakefile from Crypto++ & MinGW

But there are several issue:

• I've compile error if I try to build it as shared library;
• On my machine it works (intel i5 (2nd generation) with Windows 7 ) but on Windows Xp on an Intel atom D2500 an error occured (no entry point for memmove_s in msvcrt.dll )

When I try to build as shared library I've the following error:

make dll
make: *** No rule to make target 'cryptopp.dll', needed by 'cryptest.import.exe'. Stop.
make libcryptopp.dll
// ...

Does someone has compiled succeful crypto++ with mingw 4.8.1? This is the snippet of my makefile:

Edit

To let it work I've forced the funcion memmove_s defined in misc.h (of cryptopp) to be defined inlined and now works also on windows xp (where memmove_s is not defined in msvcrt.dll).

Question: Can I change the mscvrt.dll of windows xp with one defined on Windows 7?

Answer 1

A way to build it is using qmake:

• I removed GNUMakefile,
• qmake -project
• I open the pro file into QtCreator, changed TEMPLATE to lib and added ws2_32 to lib

The pro file now looks something this

TEMPLATE = lib
INCLUDEPATH += .
CONFIG -= qt
HEADERS += ...
SOURCES += ...

win32-g++ {
    QMAKE_CXXFLAGS += -msse -msse2 -msse3 -mssse3
    LIBS += -lws2_32
}

It seems work.

Answer 2

it's a try

put modexppc.cpp to your CRYPTOPP folder.

modexppc.cpp

// modexppc.cpp - written and placed in the public domain by Wei Dai

#include "pch.h"

#ifndef CRYPTOPP_IMPORTS

#include "modexppc.h"
#include "asn.h"
NAMESPACE_BEGIN(CryptoPP)


NAMESPACE_END

#endif

I sent a patch fixing memmove_s in Windows XP to the MinGW developer team. It's been accepted and it will soon appear in the newer MinGW builds. By now it should be available on the CentOS 7 MinGW distribution and Fedora 21 MinGW.

Crypto++ 5.6.2 now builds fine without modification on MinGW, using make (and setting CC, CXX and PATH environment variables correctly). Tested on CentOS 7, which uses MinGW 4.9 IIRC.
