摘要

本文記述如何在windows 10上編譯mod_wsgi ( Python3.5 + Apache-2.4.39 )

---

環(huán)境

• win 10
• Apache-2.4.39 - https://www.apachelounge.com/download/
• Python-3.5
• Visual Studio 2019 (含c++開(kāi)發(fā)組件)
• mod_wsgi - https://github.com/GrahamDumpleton/mod_wsgi [ 時(shí)效性: 本文用到的源碼下載于 2019-06-15 ]

注意 - Python >= 3.7會(huì)導(dǎo)致編譯失敗

mod_wsgi的源碼中存在如下內(nèi)容, 而python37.lib文件中不存在函數(shù)PyOS_AfterFork_Child()，這就會(huì)導(dǎo)致使用的Python版本大于等于3.7都會(huì)導(dǎo)致編譯失敗，并在鏈接時(shí)提示錯(cuò)誤 ：無(wú)法解析的外部符號(hào)。
因此，本文使用Python 3.5 進(jìn)行mod_wsgi的編譯

            
              
                if
              
              
                (
              
              wsgi_python_initialized 
              
                &&
              
              
                !
              
              wsgi_python_after_fork
              
                )
              
              
                {
              
              
                #
                
                  if
                
                 PY_MAJOR_VERSION > 3 || (PY_MAJOR_VERSION == 3 && PY_MINOR_VERSION >= 7)
              
              
                PyOS_AfterFork_Child
              
              
                (
              
              
                )
              
              
                ;
              
              
                #
                
                  else
                
              
              
                PyOS_AfterFork
              
              
                (
              
              
                )
              
              
                ;
              
              
                #
                
                  endif
                
              
              
                }

編譯方法

1. 找到編譯器 cl.exe， 將其位置寫入用戶環(huán)境變量PATH中。注意，請(qǐng)保證所有組件的位數(shù)一致，如均為64位，或均為32位。例如，在64位機(jī)器上編譯64位程序，需要使用 …MSVC編譯器目錄\bin\Hostx64\x64\cl.exe

2. 在 https://github.com/GrahamDumpleton/mod_wsgi 下載mod_wsgi源碼，解壓到當(dāng)前文件夾

3. 進(jìn)入目錄mod_wsgi/win32/，此目錄存放編譯mod_wsgi需要的Makefile文件，但到2019/06/15為止，里面沒(méi)有使用VS 2019和Python 3.5的Makefile，因此，接下來(lái)需要做三件事

   • 復(fù)制"ap24py34-win64-VC10.mk"，重命名為"ap24py35-win64-VC16.mk"
   • 復(fù)制"common-VC10.mk"，重命名為"common-VC16.mk"
   • 復(fù)制"build-win64-VC10.bat"，重命名為"build-win64-VC16.bat"

4. 修改ap24py35-win64-VC16.mk為如下內(nèi)容

                   
                     APACHE_ROOTDIR = Apache2.4的文件夾路徑
   
   PYTHON_ROOTDIR = Python3.5的文件夾路徑
   PYTHON_VERSION = 35
   
   MSVC_INCLUDE = MSVC編譯器的頭文件路徑
   MSVC_LIB = MSVC編譯器的庫(kù)文件路徑
   
   WINSDK_INCLUDE_UM = windows sdk的um頭文件路徑
   WINSDK_INCLUDE_UCRT = windows sdk的ucrt頭文件路徑
   WINSDK_INCLUDE_SHARE = windows sdk的shared頭文件路徑
   
   WINSDK_LIB_UCRT = windows sdk的ucrt庫(kù)文件路徑
   WINSDK_LIB_UM = windows sdk的um庫(kù)文件路徑
   
   include common-VC16.mk
   
   
                   
                 

   示例:

                   
                     APACHE_ROOTDIR = D:\App-Server\Apache24.39-Win64-VS16\Apache24
   
   PYTHON_ROOTDIR = D:\Dev\Python\Python35
   PYTHON_VERSION = 35
   
   MSVC_INCLUDE = C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\include
   MSVC_LIB = C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\lib\x64
   
   WINSDK_INCLUDE_UM = C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\um
   WINSDK_INCLUDE_UCRT = C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\ucrt
   WINSDK_INCLUDE_SHARE = C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\shared
   
   WINSDK_LIB_UCRT = C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17763.0\ucrt\x64
   WINSDK_LIB_UM = C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17763.0\um\x64
   
   include common-VC16.mk
   
   
                   
                 

5. 修改 common-VC16.mk為如下內(nèi)容

                   
                     CPPFLAGS = \
   /DWIN32 \
   /DNDEBUG \
   /I"$(MSVC_INCLUDE)" \
   /I"$(WINSDK_INCLUDE_UM)" \
   /I"$(WINSDK_INCLUDE_UCRT)" \
   /I"$(WINSDK_INCLUDE_SHARE)" \
   /I"$(PYTHON_ROOTDIR)\include" \
   /I"$(APACHE_ROOTDIR)\include"
   
   CFLAGS = \
   /MD \
   /GF \
   /Gy \
   /O2 \
   /Wall \
   /Zc:wchar_t \
   /Zc:forScope
   
   LDFLAGS = \
   /link \
   /LIBPATH:"$(APACHE_ROOTDIR)\lib" \
   /LIBPATH:"$(PYTHON_ROOTDIR)\libs" \
   /LIBPATH:"$(MSVC_LIB)" \
   /LIBPATH:"$(WINSDK_LIB_UM)" \
   /LIBPATH:"$(WINSDK_LIB_UCRT)" \
   /OPT:REF \
   /OPT:ICF=2 \
   /RELEASE \
   /SUBSYSTEM:WINDOWS
   
   LDLIBS = \
   python$(PYTHON_VERSION).lib \
   libhttpd.lib \
   libapr-1.lib \
   libaprutil-1.lib
   
   SRCFILES = ..\src\server\*.c
   
   mod_wsgi.so : $(SRCFILES)
       cl $(CPPFLAGS) $(CFLAGS) $(SRCFILES) /LD $(LDFLAGS) $(LDLIBS) /OUT:$@
   
   VARIANT = py$(PYTHON_VERSION)-VC16
   
   install : mod_wsgi.so
       copy $? $(APACHE_ROOTDIR)\modules\mod_wsgi-$(VARIANT).so
       :
       :
       :
       :
       : You now need to edit $(APACHE_ROOTDIR)\conf\httpd.conf and add:
       :
       :   LoadModule wsgi_module modules/mod_wsgi-$(VARIANT).so
       :
       :
       :
       :
   
   clean :
       del *.obj *.so *.so.manifest *.lib *.exp
   
   
                   
                 

6. 修改build-win64-VC16.bat為如下內(nèi)容

                   
                     nmake -f common-VC16.mk clean
   nmake -f ap24py35-win64-VC16.mk install
   nmake -f common-VC16.mk clean
   
                   
                 

7. 最后，在命令行中執(zhí)行此文件build-win64-VC16.bat，即可編譯成功, 編譯成功后會(huì)自動(dòng)將mod_wsgi-py??-VC??.so (本文為mod_wsgi-py35-VC16.so)復(fù)制到Apache安裝目錄的modules文件夾內(nèi)。加載此模塊仍需要自行修改Apache的配置文件。
