Problem building Crypto++ 5.6.2 on Windows with GCC 4.8.1

[Andrew Dolby]

Hello,

I built Crypto++ 5.6.2 with GCC 4.8.1 (from MinGW-w64) on Windows.

I get this error as I try to build my application (also with GCC 4.8.1) using Crypto++:

In file included from ..\..\cryptopp/randpool.h:4:0,

from ..\..\cryptopp/osrng.h:10,

from ..\test\src\test.cpp:8:

..\..\cryptopp/cryptlib.h:402:15: warning: unused parameter 'iv' [-Wunused-parameter]

virtual void Resynchronize(const byte *iv, int ivLength=-1) {throw NotImplemented(GetAlgorithm().AlgorithmName() + ": this object doesn't support resynchronization");}

This is how mingw32-make was run:

C:/MinGW/mingw64/bin/mingw32-make -f Makefile.Release

mingw32-make[1]: Entering directory 'C:/test/bin'

g++ -c -march=nocona -mtune=core2 -pipe -fno-keep-inline-dllexport -O2 -frtti -Wall -Wextra -fexceptions -mthreads -DUNICODE -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_OPENGL_ES_2 -DQT_OPENGL_ES_2_ANGLE -DQT_NEEDS_QMAIN -I..\test -I"..\..\cryptopp" -I"..\..\Qt\Qt64-5.1.0\include" -I"..\..\Qt\Qt64-5.1.0\include\QtWidgets" -I"..\..\Qt\Qt64-5.1.0\include\QtGui" -I"..\..\Qt\Qt64-5.1.0\include\QtANGLE" -I"..\..\Qt\Qt64-5.1.0\include\QtCore" -I"release" -I"." -I"..\..\Qt\Qt64-5.1.0\mkspecs\win32-g++" -o release\test.o ..\test\src\test.cpp

When I compiled Crypto++ I got no errors, though I was originally getting Resynchronize errors when I tried to build it with a different compiler.

Thanks,

Andrew Dolby

CryptoPP supports GCC 3.3 - 4.7.

I'm using gcc4.8.2 and have some other errors.

I successfully built CryptoPP-5.6.2 on Linux (Ubuntu 14.04 LTS) using GCC 4.8.2, and Mac OS X (multiple versions, up to Mavericks 10.9.5) using GCC 4.8.3 (installed via Macports) and Clang that comes with Xcode 6.1.

I did make a few patches. The most significant one dealt with the build options in the GNUmakefile, which I'm attaching for your convenience.

Note that this makefile includes FHMQV support (the actual code written by Jeffrey Walton, if I'm not mistaken). If you didn't download those sources in addition to cryptopp library, you may need to remove the related lines, or comment them out.

Since you did not list any specific errors, I can't be more specific in telling how to deal with them.

P.S. I hope that my changes for Mac OS X and for newer Intel CPU will get merged into the mainstream.

This is very helpful.

I had a problem in rijndael.cpp, apparently some kind of namespace issue.

The compiler didn't recognize Rijndael::Dec::AdvancedProcessBlocks

I changed it to Dec::AdvancedProcessBlocks and it seems to compile.

Thanks!

Its a warning, not an error. It can be safely ignored.

Crypto++ has a  lot of "unused parameter" warnings. Its par for the course with interface programming.
