今天编译了下 ioftpd ioFTPD-v7.7.3-src，遇到几个问题。

1. 需要 openssl
下载并且编译 openssl-1.0.1g

2. 遇到一处包含头文件 <ms/applink.c>
改为 <openssl/applink.c>

3. 无法找到 tcl.h
详细见代码下 Tcl.txt；作者做了说明。
Error1fatal error C1083: Cannot open include file: 'tcl.h': No such file or directory
3.1 似乎还需要 tcl 。
下载了 tcl8.6.1-src
3.2 然后无法找到 tcl85tg.lib
使用 tcl86t.lib

3.3 Error2error LNK2019: unresolved external symbol _Tcl_RegisterHandleLockFunctions referenced in function _Tcl_ModuleInitTcl.objioFTPD-v7
直接注释了，不知道有无什么影响。

3.3.1 看了眼文件夹，发现有tcl.txt，里面有详细的说明。有文档务必认真阅读文档呀。。。

3.3.2 仍有以下问题
Bad return type: void Tcl_RegisterHandleLockFunctions(void (*AcquireLock)(void),
 void (*ReleaseLock)(void))
3.3.2.1 作者所用的tcl85t.dll确有 Tcl_RegisterHandleLockFunctions

Hmm, it just occurred to me that starting with v7.1.0 the TCL libraries differ from the official TCL v8.5.8 sources because of the addition of the Tcl_RegisterHandleLockFunctions command. That was added so the TCL library can share the ioFTPD lock around process/socket creation. I've included a copy of the TCL sources I'm building from in the link at the top.

49) Tcl_RegisterHandleLockFunctions(AcquireHandleLock, ReleaseHandleLock) hasbeen added as a new exported C function to the standard TCL dlls.  Thisis the first time the TCL code has been modified for use by ioFTPD.Previously only the makefiles and command line options used for compilationwere touched.  In order to fix the race condition with new sockets beingautomatically inheritable by child processes it is necessary to share alock with the rest of the server and thus some way to communicate what toshare is required.  This function just registers 2 callback functions tocall before and after socket and/or process creation.

v7.1.0 Release Notes:

找了几个版本的tcl dll，里面均没有该函数：Tcl_RegisterHandleLockFunctions1) Files in \System:   Changed : ioFTPD.[exe,pdb] - Version 7.1.0.0.   Changed : tcl85t.[dll,pdb] - Version 8.5.2.8 (tcl version 8.5.8)   Changed : ioFTPD.ini - summary of changes by section...

The OpenSSL library is unchanged, you should be able to use anybody's compiled copy or build it yourself. We are currently using 1.0.0 but 1.0.1 is out there.

3.4 找到一处作者的说明，使用 nmake -nologo -f makefile.vc release OPTS=threads 编译 tcl ，使用这个重新编译下看看。
nmake -nologo -f makefile.vc release OPTS=threads

3.5 找不到 ioFTPD.ico ，将其路径更改如下。
IDI_ICON1               ICON                    ".\\..\\src\\ioFTPD.ico"

focus：注释掉 Tcl_RegisterHandleLockFunctions ，然后挑选感兴趣的看看。
