MFC工程中无法使用cygwin64的库
概述
开始想在MFC程序中使用cygwin64的库(静态库, 动态库(静态包含), 动态库(动态调用)).
做实验之前, 想想只要将gnu的功能封装成库(只需要封装成接口, 逻辑部分可以不动或轻微修改), 给自己工程用, 前景多美好.
现实很骨感. 试过了, 都不行, 走弯路了.
cygwin64官方文档上, 关于DLL这块, 也是给可以替换CRTinit这种VS工程用的. 如果像MFC这种框架型的工程, 根本没办法替换CRTInit的操作.
总之, 想将gnu实现包进自己工程用, 和cygwin64官方的思路就相违背. 做这种实验, 吃苦头也就是水到渠成的了.
网上关于cygwin64DLL给VS工程的资料不多, 说来说去, 都是围着官方文档在转.
在MFC中使用cygwin64的静态库
这个根本就编译不过, 因为编译出来的cygwin64库还有依赖的cygwin64底层实现, 各种编译报错.
在MFC中使用cygwin64的DLL进行静态包含
这个可以编译过, 但是运行时, 如果在DLL函数中使用了cygwin64的函数(e.g. fopen), 虽然不报错, 可是直接不好使, 文件都打不开(文件句柄为空). 原因是, cygwindll初始化无效引起的.
在MFC中使用cygwin64的DLL进行动态调用
在LoadLIbrary()就会报错, LoadLibrary都没执行完.
无源码调试看了一下调用链.
可以看到, LoadLibray()时, 会进入DLL入口函数, 然后会调用cywin1_cygwin_dll_init(), 这个初始化函数会失败, 然后走到assert报错
唯一可以使用cygwin64的方法是进程隔离来通讯
- 调用cygwin64的exe来干活
- 和cygwin64做成的exe通过本地socket来通讯, 委托cygwin64的程序实现功能.
我开始要做cygwin64DLL的原因: 因为调用批处理时候, 总是会出dos窗口. 因为这个程序是基于以前的实现堆出来的. 以前那个程序就在调用批处理时, 会不断的弹dos窗口. 这次功能行代码写完了, 就想将这个问题搞掉, 要不不像个程序啊(用户都会说这个dos弹窗问题).
然后去做cygwin64的DLL(顺便学了一下CMake的初级用法[CMake官方前4课], 用CMake来做linux程序构建的脚本, 不用自己去写Makefile了), 尝试给MFC-EXE用. 用了一个星期, 怎么玩cygwin64工程, 已经清楚了.
但是做好的cygnwin64DLL无法给MFC用.
然后思路又回到隐藏dos窗口上, 看了一些资料, 人家说确实可以调用批处理(.bat)时隐藏dos窗口, 那我的实现咋不行呢?
对了一下, 自己改了参数, CreateProcess()的参数5, 加了CREATE_NEW_CONSOLE, 有了这个参数, 就无法隐藏dos窗口.去掉这个就好了.
用了一个星期, 没有搞出新解决方法, 然后发现自己实现写错了, 还是挺难受的. 这不被自己玩了么?
cygwin64的官方用途
毕竟cygwin64官方的目的是为了将linux/gnu工程移植到window, 让linux/gnu工程代码不改或少改.
如果主程序(非cygwin64工程)想用cygwin64工程的功能, 还是进行进程隔离来使用cygwin64工程输出, 这个也是最简单的方法.
毕竟大多数人的主程序也不可能是cygwin64的工程.
cygwin64官方也没考虑让cygwin64的工程输出能包含进其他程序.
修正后的启动进程隐藏dos窗口的函数
BOOL COrderProcBase::executeCommandLine(CString cmdLine, DWORD& exitCode)
{
PROCESS_INFORMATION processInformation = { 0 };
STARTUPINFO startupInfo = { 0 };
memset(&startupInfo, 0, sizeof(STARTUPINFO));
GetStartupInfo(&startupInfo); // 可以得到以下3个信息, .cb不用自己填写了, .lpDesktop可以得到主程序的桌面位置
/*
cb 104 unsigned long
+ lpReserved 0x0000016952ea535c L"" wchar_t *
+ lpDesktop 0x0000016952ea533c L"Winsta0\\Default" wchar_t *
+ lpTitle 0x0000016952ea5212 L"D:\\...\\xParser.exe" wchar_t *
其他值还是0
*/
startupInfo.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW;
startupInfo.wShowWindow = SW_HIDE;
startupInfo.lpReserved = NULL;
startupInfo.cbReserved2 = 0;
startupInfo.lpReserved2 = NULL;
// startupInfo.cb = sizeof(startupInfo);
int nStrBuffer = cmdLine.GetLength();
// printf("%ws\n", cmdLine.GetString());
// !!! 如果参数5加了 CREATE_NEW_CONSOLE, 就会出现dos窗口
// cmdLine.GetBuffer(), cmdLine.GetBuffer(nStrBuffer) 返回的指针地址都一样
BOOL result = CreateProcess(NULL, cmdLine.GetBuffer(nStrBuffer),
NULL, NULL, FALSE,
NORMAL_PRIORITY_CLASS | CREATE_NO_WINDOW /* | CREATE_NEW_CONSOLE */,
NULL, NULL, &startupInfo, &processInformation);
cmdLine.ReleaseBuffer();
if (!result) {
// CreateProcess() failed
// Get the error from the system
LPVOID lpMsgBuf;
DWORD dw = GetLastError();
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
NULL, dw, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR)&lpMsgBuf, 0, NULL);
// Display the error
CString strError = (LPTSTR)lpMsgBuf;
TRACE(_T("::executeCommandLine() failed at CreateProcess()\nCommand=%s\nMessage=%s\n\n"), cmdLine, strError);
// Free resources created by the system
LocalFree(lpMsgBuf);
// We failed.
return FALSE;
}
else {
// Successfully created the process. Wait for it to finish.
WaitForSingleObject(processInformation.hProcess, INFINITE);
// Get the exit code.
result = GetExitCodeProcess(processInformation.hProcess, &exitCode);
// Close the handles.
CloseHandle(processInformation.hProcess);
CloseHandle(processInformation.hThread);
if (!result) {
// Could not get exit code.
TRACE(_T("Executed command but couldn't get exit code.\nCommand=%s\n"), cmdLine);
return FALSE;
}
// We succeeded.
return TRUE;
}
}
动态载入DLL的实现 - LateLoad.h
在做动态载入DLL时, 翻出以前在开源工程基础上改的实现, 还是那么好用.
作为研发, 平时做些奇怪没用的小实验, 只要归档了, 以后还是能用上的. 力气不白费.
修正了原版9个参数的动态调用函数定义.
增加了10~12个参数的动态函数定义.
#ifndef __LATE_LOAD__H__
#define __LATE_LOAD__H__
#if _MSC_VER > 1000
#pragma once
#endif
#include ();" member
Is_NonExistantFunction();
// If it exists, it will return TRUE. False if it does not exist
-------------------------------------------
Let's look at the various defines that are used...
LATELOAD_BEGIN_CLASS(CUser32Wrapper,user32,FALSE)
CUser32Wrapper - the class that will be created
user32 - the library that will be loaded
FALSE - determines if "FreeLibrary()" will be called in the destructor.
LATELOAD_FUNC_0(NULL,HCURSOR,WINAPI,GetCursor)
NULL - if the ProcAddress was not loaded, this value is returned in the call to that func
HCURSOR - the return type for the function
WINAPI - function calling convention
GetCursor - the exported function
LATELOAD_FUNC_1 (up to _9)
Identical to LATELOAD_FUNC_0, except it allows 1-9 parameters to the function
LATELOAD_FUNC_0_ (up to _9)
Same as before, but for use with NULL return types
LATELOAD_END_CLASS()
finalizes the class declaration
