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.
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.
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
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?
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.

// 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;
}
}
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.

Module : LateLoad.h
Purpose: I was tired of constantly re-writing LoadLibrary & GetProcAddress code,
over & over & over again. So I created a series of macros that will
define & create a wrapper class to do it all for me.
This is NOT an end-all-be-all solution for loading DLLs. This is just a
handy lightweight helper when you would use LoadLibrary/GetProcAddress.
For more information on DLLs, check out MSDN.
This was inspired by my own need, as well as a nice little MSDN article
titled "DLLs the Dynamic Way" by "MicHael Galkovsky"
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndllpro/html/dlldynamic.asp
Unfortunatly, there was no source to go with the article. So, I wrote this
version quite a bit differently.

License: Use it however you like as a compiled portion of your product(s).
Don't be a jerk by claiming the it as your own.
Usage : The following will declare the class "CUser32Wrapper" that will load
function pointer(s) from USER32.DLL. Those function names will become
member function(s) of the newly created class.
LATELOAD_BEGIN_CLASS(CUser32Wrapper,user32,FALSE)
LATELOAD_FUNC_0(NULL,HCURSOR,WINAPI,GetCursor)
LATELOAD_FUNC_1(NULL,HANDLE,WINAPI,NonExistantFunction,BOOL)
LATELOAD_END_CLASS()
// The above statements will auto-generate a class that functionaly equivalent to...
class CUser32Wrapper : public CLateLoadBase
{
public:
BOOL Is_GetCursor();
HCURSOR WINAPI GetCursor();
BOOL Is_NonExistantFunction();
HANDLE WINAPI NonExistantFunction();
};
// And usage is even easier
CUser32Wrapper uw;
HCURSOR h = uw.GetCursor();
// And for DLLs missing a function export, you can still use the member function!
uw.NonExistantFunction(true);
// It will just return the default non-existant value in the definition
// To determine if the funtion was imported, use the "BOOL Is_<FunctionName>();" 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
