PyCrypto builds neither with MSVC nor MinGW

[Alec Taylor]

PIL, PyCrypto and many other modules require a C compiler and linker.

Unfortunately neither install on my computer, with a PATH with the following:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC
C:\libraries\MinGW\msys\1.0\bin
C:\libraries\MinGW
C:\Python27\Scripts

Output from G:\pycrypto>vcvarsall.bat
Setting environment for using Microsoft Visual Studio 2010 x86 tools.

Error output from G:\pycrypto>python setup.py build --compiler msvc
http://pastebin.com/nBsuXDGg

Error output from G:\pycrypto>python setup.py build --compiler mingw32
1> log1 2> log2
Log1: http://pastebin.com/yG3cbdZv
Log2: http://pastebin.com/qvnshPeh

Will there ever be support for newer MSVC versions? - Also, why
doesn't even MinGW install PyCrypto for me?

Thanks for all suggestions,

Alec Taylor

A couple of comments. You will need to complile either GMP or MPIR
first.

MPIR is a windows friendly fork of GMP and I use it create Windows
binaries
for gmpy.

Python 2.7 uses VS2008. I use the command line compiler included with
in
Microsoft's SDK 7.0 which is still available for download. I have
step-
by-step build instructions included in gmpy's source download. I would
try to build MPIR and gmpy first and then adapt/modify the process for
PyCrypto.

MPIR home page: www.mpir.org
gmpy source: gmpy.googlecode.com/files/gmpy-1.15.zip

doesn't even MinGW install PyCrypto for me?

Thanks for all suggestions,

Thanks all for your replies.

I have now installed MSVC8 and YASM.

I was able to successfully run configure.bat and make.bat (including
make.bat check).

However, I'm unsure what to do about install, since there is no
install arg. Do I copy it across to my VC\bin folder, or does it need
it's own place in PATH + system variables?

I am asking because I don't know where it is looking for the MPIR library.

Thanks for all suggestions,

Alec Taylor

Thanks all for your replies.

I have now installed MSVC8 and YASM.

I assume you installed Visual Studio. I've omitted the commands to use
the SDK compiler below.

I was able to successfully run configure.bat and make.bat (including
make.bat check).

However, I'm unsure what to do about install, since there is no
install arg. Do I copy it across to my VC\bin folder, or does it need
it's own place in PATH + system variables?

The following is just a guess.

I copy the files to a convenient location and then specify that
location to setup.py. Below is an excerpt from my build process.

mkdir c:\src\lib
mkdir c:\src\include
xcopy /Y mpir.h c:\src\include\*.*
xcopy /Y win\mpir.lib c:\src\lib\*.*

python setup.py build_ext -Ic:\src\include -Lc:\src\lib install

 

[Alec Taylor]

Thanks, but to get it to work with pip, wouldn't I need to add it to
PATH? - Or can I just add those library args to pip?

 

[Case Van Horsen]

Thanks, but to get it to work with pip, wouldn't I need to add it to
PATH? - Or can I just add those library args to pip?

I don't think so. pyCrypto probably builds a single DLL so the MPIR library is
statically linked into that DLL. Only the innvocation of setup.py should need
to refer to the MPIR library locations. I don't use pip so I'm not sure how to
get pip to install the resulting DLL, etc.

On a brand new Windows install now, with a brand new VS8 installed
with new YASM and MPIR in c:\usr\src\include and c:\usr\src\lib.

But it still isn't working:

FYI: When running "vcvarsall" manually, I get a variety of linker
errors, even though I have the SDK and everything else installed:

On a brand new Windows install now, with a brand new VS8 installed
with new YASM and MPIR in c:\usr\src\include and c:\usr\src\lib.

But it still isn't working:

This was a little challenging. I looked through the setup.py to figure out what assumptions their build process made. First, the file pycrypto-2.5\src\inc-msvc\config.h must be modified. Below is the file I used:

config.h
===================================================================
/* Define to 1 if you have the declaration of `mpz_powm', and to 0 if you
don't. */
#define HAVE_DECL_MPZ_POWM 1

/* Define to 1 if you have the declaration of `mpz_powm_sec', and to 0 if you
don't. */
#define HAVE_DECL_MPZ_POWM_SEC 0

/* Define to 1 if you have the `gmp' library (-lgmp). */
#undef HAVE_LIBGMP

/* Define to 1 if you have the `mpir' library (-lmpir). */
#define HAVE_LIBMPIR 1

/* Define to 1 if you have the <stdint.h> header file. */
#define HAVE_STDINT_H 1
===================================================================

Although I was able to specify an include directory for mpir.h with -Ic:\usr\include, I was not able specify a lib directory with -Lc:\usr\lib. It looks like setup.py does not honor the -L option. So I finally gave up and just copied the mpir.h file into my Python27\include directory and the mpir.lib file into my Python27\libs directory.

After copying the files "python setup.py install" was successful. I createda binary installer with "python setup.py bdist-wininst".

There may be a cleaner way to build PyCrypto, but these steps worked for me..

It almost seems that python can't find all its files. Are you using a
macro or batch file to invoke python. I actually used

"c:\x64\Python27\python.exe setup.py install"

IIRC, I've had issues with a DOSKEY macro before so now I explicitly
use the full path to python.exe.

Otherwise I'm stumped.

Oh wait, just realised it was loading the (x86) tools. Doing a quick
search I noticed that I didn't have the x64 components installed, so
loading up the MSVC08 setup again and installing it, then:
copying vcvarsamd64.bat to vcvarsall.bat and adding its directory
(C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\) to
PATH....

AND IT WORKS!

I also had the unresolved externals problem (not the mdir.h problem, though)
and my solution was different.
a) reinstall correct python2.6.4, using an Intel-flavor msi vice
AMD64-flavor
b) source the c:\program files(x86\microsoft visual studio
9.0\vc\bin\vcvars32.bat
and shazzaaaam the pycrypto build + install worked fine.
My CPU is Intel not AMD so I apparently had a bogus python install.

For most open-software distributions:

AMD64 is the 64 bit build for both AMD and Intel. Probably referred to
as AMD64 because AMD had a compatible 64 bit processor while Intel was
still fooling around with Merced for its 64 bit stuff.

X86 is the 32 bit build for both AMD and Intel.
