看起來 libiconv.lib 裡面已經有一份 msvcrt.lib 了，你的程式也要連結 msvcrt.lib，導至有雙份標準函式庫實體。

建議你用 dll 與 libiconv 連結。

你需要設定 project 的 include/library path，指到 %ProgramFiles%\GnuWin32\include 與 %ProgramFiles%\GnuWin32\lib 去。

沒有 source 的即可。

Usually, when there is access violation errors, it means there is something wrong with your pointers.

For example, when pointer p (which point to a structure) is NULL, p-&ltfield will cause such kind of error.
