libevhtp windows下编译

Question

有人在windows下编译过libevhtp吗，求编译过程及编译库

Answer 1

安装OpenSSL
本文中用到的OpenSSL版本是openssl-OpenSSL_1_0_1u （开始使用的版本是openssl-OpenSSL_1_1_0，但是在源码中没有找到ms\do_ms）。

构建需求（Visual C++）
In addition to the requirements and instructions listed in INSTALL,
this are required as well:

You need Perl. We recommend ActiveState Perl, available from https://www.activestate.com/ActivePerl.
You also need the perl module Text::Template, available on CPAN. Please read NOTES.PERL for more information.
You need a C compiler. OpenSSL has been tested to build with these:

Visual C++
Netwide Assembler, a.k.a. NASM, available from http://www.nasm.us,
is required if you intend to utilize assembler modules. Note that NASM is the only supported assembler. The Microsoft provided assembler is NOT
supported.

本机的部分环境变量如下：

%SystemRoot%\system32;
%SystemRoot%;
D:\Strawberry\c\bin;
D:\Strawberry\perl\site\bin;
D:\Strawberry\perl\bin;
C:\Program Files (x86)\NASM;
​

构建OpenSSL
打开Visual Studio Command Prompt (2010) ，依次输入下列命令：

$ cd openssl-OpenSSL_1_0_1u
$ perl Configure VC-WIN32 --prefix="F:\ThirdParty\openssl\openssl" --openssldir="F:\ThirdParty\openssl\ssl"
$ ms\do_ms
$ nmake -f ms\nt.mak
$ nmake -f ms\nt.mak test
$ nmake -f ms\nt.mak install
Configure命令对安装进行配置，其中VC-WIN32是指定构建的平台，可选的参数有（选择其中之一）：VC-WIN32 | VC-WIN64A | VC-WIN64I | VC-CE ，如果想要构建debug版本使用debug-VC-WIN32参数即可。--prefix参数指定库文件和头文件（lib、include、bin）的安装位置，如果不指定将会默认安装到%ProgramFiles(86)%\OpenSSL目录。--openssldir参数指定OpenSSL的安装路径，如果不指定将会默认安装到%CommonProgramFiles(86)%\SSL目录。
do_ms是源代码ms目录下的批处理文件，如果想要构建64位的库使用ms\do_win64a命令。
nmake用于构建源码，默认构建的静态库，如果想要构建动态库可以指定使用ms\ntdll.mak 。
更详细的安装说明请查看OpenSSL源文件目录下的INSTALL 、NOTES.WIN和NOTES.PERL文件，但是千万不要盲目相信源目录下的安装方法。

​

安装libevent
本例中使用的libevent版本是2.0.22-stable ，使用nmake编译。更新版本已经支持使用CMake编译。

编译32位库打开Visual Studio Command Prompt (2010) ，编译64位库打开Visual Studio x64 Win64 Command Prompt (2010) ，依次输入下列命令：

$ cd
$ nmake -f makefile.nmake

可以跟根据实际情况修改makefile.nmake文件，已知可以修改的配置如下：

WATCH OUT! This makefile is a work in progress. It is probably missing

tons of important things. DO NOT RELY ON IT TO BUILD A GOOD LIBEVENT.

By default, Makefile.nmake builds without OpenSSL, as before. But if you uncomment the line:

OPENSSL_DIR=F:\ThirdParty\openssl\openssl

!IFDEF OPENSSL_DIR
SSL_CFLAGS=/I$(OPENSSL_DIR)\include /DEVENT__HAVE_OPENSSL
!ELSE
SSL_CFLAGS=
!ENDIF

Needed for correctness

#CFLAGS=/IWIN32-Code /Iinclude /Icompat /DWIN32 /DHAVE_CONFIG_H /I.
CFLAGS=/IWIN32-Code /Iinclude /Icompat /DWIN32 /DHAVE_CONFIG_H /I. $(SSL_CFLAGS)

添加WIN32_WINNT宏定义（根据系统平台更改值，好像已经可以省略）

CFLAGS=$(CFLAGS) /D_WIN32_WINNT=0x0501

消除DEPRECATE警告

CFLAGS=$(CFLAGS) /D_CRT_SECURE_NO_DEPRECATE /D_CRT_NONSTDC_NO_DEPRECATE

For optimization and warnings

debug模式/Od（禁用优化）

CFLAGS=$(CFLAGS) /Od /W3 /wd4996 /nologo

release模式/Ox（完全优化）

CFLAGS=$(CFLAGS) /Ox /W3 /wd4996 /nologo

XXXX have a debug mode (debug模式添加-D_DEBUG)

CFLAGS=$(CFLAGS) -D_DEBUG

debug版本添加调试信息，x86可以使用/ZI

#CFLAGS=$(CFLAGS) /ZI

debug版本添加调试信息，x64可以使用/Zi

CFLAGS=$(CFLAGS) /Zi

LIBFLAGS=/nologo

64位库添加/MACHINE:X64

LIBFLAGS=$(LIBFLAGS) /MACHINE:X64

CORE_OBJS=event.obj buffer.obj bufferevent.obj bufferevent_sock.obj \
bufferevent_pair.obj listener.obj evmap.obj log.obj evutil.obj \
strlcpy.obj signal.obj bufferevent_filter.obj evthread.obj \
bufferevent_ratelim.obj evutil_rand.obj
WIN_OBJS=win32select.obj evthread_win32.obj buffer_iocp.obj \
event_iocp.obj bufferevent_async.obj
EXTRA_OBJS=event_tagging.obj http.obj evdns.obj evrpc.obj

添加输出文件*_openssl.lib *_openssl.obj

!IFDEF OPENSSL_DIR
SSL_OBJS=bufferevent_openssl.obj
SSL_LIBS=libevent_openssl.lib
!ELSE
SSL_OBJS=
SSL_LIBS=
!ENDIF

添加pthreads输出文件

THR_OBJS=evthread.obj
THR_LIBS=libevent_pthreads.lib

添加$(SSL_OBJS)

ALL_OBJS=$(CORE_OBJS) $(WIN_OBJS) $(EXTRA_OBJS) $(SSL_OBJS) $(THR_OBJS)

添加$(SSL_LIBS)

STATIC_LIBS=libevent_core.lib libevent_extras.lib libevent.lib $(SSL_LIBS) $(THR_LIBS)

all: static_libs tests

static_libs: $(STATIC_LIBS)

libevent_core.lib: $(CORE_OBJS) $(WIN_OBJS)
lib $(LIBFLAGS) $(CORE_OBJS) $(WIN_OBJS) /out:libevent_core.lib

libevent_extras.lib: $(EXTRA_OBJS)
lib $(LIBFLAGS) $(EXTRA_OBJS) /out:libevent_extras.lib

libevent.lib: $(CORE_OBJS) $(WIN_OBJS) $(EXTRA_OBJS)
lib $(LIBFLAGS) $(CORE_OBJS) $(EXTRA_OBJS) $(WIN_OBJS) /out:libevent.lib

how to make "libevent_openssl"

libevent_openssl.lib: $(SSL_OBJS)
lib $(LIBFLAGS) $(SSL_OBJS) /out:libevent_openssl.lib

how to make "libevent_pthreads"

libevent_pthreads.lib: $(THR_OBJS)
lib $(LIBFLAGS) $(THR_OBJS) /out:libevent_pthreads.lib

添加clean

clean:
del $(ALL_OBJS)
del $(STATIC_LIBS)
cd test
$(MAKE) /F Makefile.nmake clean
cd ..

tests:
cd test

$(MAKE) /F Makefile.nmake

如果libevhtp支持cmake时提示LIBEVENT_PTHREADS_LIBRARY(ADVANCED)错误则需要编译输出libevent_pthreads.lib ，否则不需要。

安装libevhtp
安装libevhtp是个很麻烦的过程，遇到了很多问题，经过无数次的失败与重试，终于编译成功了。

打开命令提示符工具或Visual Studio Command Promp ，依次输入下列命令：

$ cd /build
$ cmake -G "MinGW Makefiles" $(params) ..
$ mingw32-make # 或执行 nmake

可以使用cmake-gui工具替换cmake命令，其中$(params)参数的详细信息如下（Commandline options块中，不需全部输入，仅供参考）：
