Compiling Python with Visual Studio 2010

Issues

List of issues related to Visual Studio 2010:

* issue 13210: parent issue

* issue 10469: test_asyncore blocks forever

* issue 4431: manifest handling

* issue7833: patch to avoid the use of manifests

* issue6807: problem with msi for installer creation

* issue2286: crash on test_marshal

* patch wininst

Prepare environment

* grab Python 2.7.2 sources from python.org

* Define compilation environment:

For 32 bits:
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\Tools\vsvars32.bat"

For 64 bits:
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" amd64

It is necessary to have svn in the PATH

Compile additional libraries

* Download the dependencies:

cd Python-2.7.2
Tools\buildbot\external-common.bat

* Correct the dependencies for VS 2010:

* Compile the dependencies:

For 32 bits:
$ Tools\buildbot\external.bat

For 64 bits:
$ Tools\buildbot\external-amd64.bat

* Get openssl 1.0.0e

You need perl to compile openssl

set PATH=%PATH%;C:\Perl\bin
cd openssl-1.0.0e

For 32 bits:
perl Configure --openssldir=D:\NotBackedUp\support\openssl-1.0.0e\ enable-camellia disable-idea VC-WIN32
ms\do_ms.bat # possibly .\ms\do_nasm.bat with http://nasm.sf.net
nmake -f ms\nt.mak
nmake -f ms\ntdll.mak


For 64 bits:
perl Configure --openssldir=D:\NotBackedUp\support\openssl-1.0.0e\ enable-camellia disable-idea VC-WIN64A
ms\do_win64a.bat
nmake -f ms\nt.mak
nmake -f ms\ntdll.mak

## $ nmake -f ms\ntdll.mak test

* Open Python-2.7.2\PCbuild\pcbuild.sln with Visual Studio (automatic conversion)

* Close the solution

* Modify Python-2.7.2\PCbuild\_bsddb.vcxproj for each source line, from:

    <ClCompile Include="crypto\aes_method.c" />

to

    <ClCompile Include="$(bsddbDir)\..\crypto\aes_method.c" />

* Modify Python-2.7.2\PCbuild\_ssl.vcxproj and Python-2.7.2\PCbuild\_hashlib.vcxproj - remove each PreBuildEvent section (could not get build_ssl.py to work, prefered manual compilation)

* Open Python-2.7.2\PCbuild\pcbuild.sln with Visual Studio

* Change to Release (for 64 bits: "Release | x64")

* Choose in menu "View" => "Property Manager"

* open project _bsddb > "Release | Win32" > pyd > pyproject > User macros (for 64 bits: "Release | x64")

* change value of opensslDir, from "$(externalsDir)\openssl-0.9.8d" to "$(externalsDir)\openssl-1.0.0d"

* Change properties in project tkinter > Linker > Input > Additional Dependencies > edit:

For 32 bits: remove $(tcltkLib) and add $(tcltkDir)\lib\tcl85g.lib;$(tcltkDir)\lib\tk85g.lib;

For 64 bits: remove $(tcltk64Lib) and add $(tcltk64Dir)\lib\tcl85g.lib;$(tcltk64Dir)\lib\tk85g.lib;

* Build solution

Use either the UI or following commands:

For 32 bits:
msbuild PCbuild\pcbuild.sln  /p:Configuration="Release" /p:Platform="Win32"

For 64 bits:
msbuild PCbuild\pcbuild.sln  /p:Configuration="Release" /p:Platform="x64"

* Build project bdist_wininst

* copy Python-2.7.2/PC/pyconfig.h to Python-2.7.2/pyconfig.h (necessary otherwise distutils complains that it can't find the file when compiling packages)

* Test python:

cd PCbuild;

For 32 bits:
rt.bat -q -uall -rwW

For 64 bits:
rt.bat -q -x64 -uall -rw

Note: currently the tests will lock on test_asyncore: may be related to http://bugs.python.org/issue10469.

Create installer

* get http://sourceforge.net/projects/pywin32/files/pywin32/Build216/pywin32-216.zip/download * unzip pywin32-216.zip

cd pywin32-216

* modify files so that it will compile with visual Studio 2010:

Merging Microsoft.VC100.CRT in the package will fail for the moment, so you need to apply the following patch to msi.py:
