windows10下VS2019编译jpegsrc.v9e.tar.gz为lib静态库(已验证)

杰林码 2023-05-27 08:00:03
简介windows10下VS2019编译jpegsrc.v9e.tar.gz为lib静态库(已验证)

一、下载jpegsrc

1、下载JPEG库的源代码 http://www.ijg.org/files/
2、这里使用最新的jpegsr9e.zip ,别下载错误了(jpegsrc.v9e.tar.gz 是RAM架构的仅支持32位)
3、解压jpegsr9e.zip到d盘,如:D:jpeg-9e

二、vs2019编译windows x86(x64)架构的lib库

启动Developer Command Prompt for VS 2019.exe,通过命令进入到D:jpeg-9e:

CD D:jpeg-9e

直接使用命令(注意vs2019是setup-v16,其他的版本需要查一下):

NMAKE /f makefile.vs setup-v16

在这里插入图片描述
此时在文件夹内出现了jpeg.sln,用vs2019打开,并选择x86或则x64:
在这里插入图片描述
编译时需要选择架构类型:
在这里插入图片描述
win32和x64代表x86和x64,也可以选择ARM。
在这里插入图片描述
于是生成了:
在这里插入图片描述
然后通过包含调用lib即可:

#include "jpeglib.h"

大家也可以直接下载vs2019的项目文件:

三、vs2019编译windows ARM架构的lib库

注意如果下错了jpegsrc.v9e.tar.gz ,采用的是ARM架构下的会出现错误:
makefile.vc(11) : fatal error U1052: 未找到文件“win32.mak”
Stop.
此时请将下面的代码通过txt另存为:Win32.Mak,放在D:jpeg-9e中,然后再执行上面的命令。

# Win32.Mak - Win32 application master NMAKE definitions file for the
#     Microsoft Windows SDK programming samples
#           Copyright (C) Microsoft Corporation
# -------------------------------------------------------------------------
# This files should be included at the top of all MAKEFILEs as follows:
#  !include <Win32.Mak>
# -------------------------------------------------------------------------
#
# Define APPVER = [ 4.0 | 5.0 | 5.01 | 5.02 | 6.0 | 6.1] prior to including win32.mak to get
#  build time checking for version dependencies and to mark the executable
#  with version information.
#
# Define TARGETOS = [ WIN95 | WINNT | BOTH ] prior to including win32.mak
#  to get some build time checking for platform dependencies.
#
# Define TARGETLANG = [ LANG_JAPANESE | LANG_CHINESE | LANG_KOREAN ] prior
#  to including win32.mak to getcompile & link flags for building
#  applications to run on Far-East Windows. (This is an optional parameter.
#  The system locale is the default.)
#
# Define _WIN32_IE = [ 0x0300 | 0x0400 | 0x0500 | 0x0600] prior to including win32.mak to
#  get compile and link flags for building applications and components to
#  run on Internet Explorer. (This is an optional parameter.  IE 4.0 is
#  the default.)
#
# -------------------------------------------------------------------------
# NMAKE Options
#
# Use the table below to determine the additional options for NMAKE to
# generate various application debugging, profiling and performance tuning
# information.
#
# Application Information Type         Invoke NMAKE
# ----------------------------         ------------
# For No Debugging Info                nmake nodebug=1
# For Working Set Tuner Info           nmake tune=1
# For Call Attributed Profiling Info   nmake profile=1
# For COLE 32->64-bit Porting Tool     nmake COLE_64=1
#
# Note: The three options above are mutually exclusive (you may use only
#       one to compile/link the application).
#
# Note: creating the environment variables NODEBUG, TUNE, and PROFILE is an
#       alternate method to setting these options via the nmake command line.
#
# Note: to use the COLE_64 option, you need to set your build environment
#       for 64-bit compilations.
#
# Note: TUNE and PROFILE do nothing for 64bit compilation
#
# Additional NMAKE Options             Invoke NMAKE
# ----------------------------         ------------
# For No ANSI NULL Compliance          nmake no_ansi=1
# (ANSI NULL is defined as PVOID 0)

# When building single-threaded applications you can link your executable
# with either LIBC, LIBCMT, or MSVCRT, although LIBC will provide the best
# performance.
#
# When building multi-threaded applications, either LIBCMT or MSVCRT can
# be used as the C-Runtime library, as both are multi-thread safe.
#
# Note: Any executable which accesses a DLL linked with MSVCRT.LIB must
#       also link with MSVCRT.LIB instead of LIBC.LIB or LIBCMT.LIB.
#       When using DLLs, it is recommended that all of the modules be
#       linked with MSVCRT.LIB.
#
# Note: The macros of the form xDLL are used when linking the object with
#       the DLL version of the C Run-Time (that is, MSVCRT.LIB).  They are
#       not used when the target object is itself a DLL.
