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.
