PC端openssl和libevent的編譯流程

準備工作：

1、Perl

建議使用5.30以上版本，本人在使用時發現28的版本好像在配置openssl的時候有問題。
下載地址：http://strawberryperl.com/
ps：ActivePerl 和 Strawberry Perl 都可以

2、nasm

下載地址：https://www.nasm.us/pub/nasm/stable/
nasm需要配置環境變量
安裝後打開vs編譯環境（我編譯的是vs2010）
驗證perl和nasm是否安裝成功

編譯openssl
進入openssl-1.0.2j目錄
執行：

Perl Configure no-asm VC-WIN32 --prefix=D:\openssl_lib

開始編譯

ms\do_nasm
（靜態庫）
nmake -f ms\nt.mak
nmake -f ms\nt.mak test
nmake -f ms\nt.mak install

最後生成文件在openssl_lib目錄下

Libevent編譯
進入libevent-2.0.22-stable目錄
替換Makefile.nmake內容如下：

# WATCH OUT!  This makefile is a work in progress.             -*- makefile -*-
#
# I'm not very knowledgeable about MSVC and nmake beyond their most basic
# aspects.  If anything here looks wrong to you, please let me know.
# If OPENSSL_DIR is not set, builds without OpenSSL support.  If you want
# OpenSSL support, you can set the OPENSSL_DIR variable to where you
# installed OpenSSL.  This can be done in the environment:
#   set OPENSSL_DIR=c:\openssl
# Or on the nmake command line:
#   nmake OPENSSL_DIR=C:\openssl -f Makefile.nmake
# Or by uncommenting the following line here in the makefile...
# OPENSSL_DIR=c:\openssl
!IFDEF OPENSSL_DIR
SSL_CFLAGS=/I$(OPENSSL_DIR)\include /DEVENT__HAVE_OPENSSL
!ELSE
SSL_CFLAGS=
!ENDIF
# Needed for correctness
CFLAGS=/IWIN32-Code /IWIN32-Code/nmake /Iinclude /Icompat /DHAVE_CONFIG_H  /DWIN32 /I. $(SSL_CFLAGS)
# For optimization and warnings
CFLAGS=$(CFLAGS) /Ox /W3 /wd4996 /MTd /nologo 
# XXXX have a debug mode
LIBFLAGS=/nologo
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
!IFDEF OPENSSL_DIR
SSL_OBJS=bufferevent_openssl.obj
SSL_LIBS=libevent_openssl.lib
!ELSE
SSL_OBJS=
SSL_LIBS=
!ENDIF
ALL_OBJS=$(CORE_OBJS) $(WIN_OBJS) $(EXTRA_OBJS) $(SSL_OBJS)
STATIC_LIBS=libevent_core.lib libevent_extras.lib libevent.lib $(SSL_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
libevent_openssl.lib: $(SSL_OBJS)
lib $(LIBFLAGS) $(SSL_OBJS) /out:libevent_openssl.lib
clean:
del $(ALL_OBJS)
del $(STATIC_LIBS)
tests:

!IFDEF OPENSSL_DIR
 
!ELSE
 
!ENDIF

最後執行：

nmake /f Makefile.nmake OPENSSL_DIR=D:\openssl_lib

openssl_lib為上面生成文件路徑
最後生成lib文件在當前libevent-2.0.22-stable目錄
