可執行文件除非使用終端，否則不會在windows中運行

Question

我正在使用SDL_TFF庫並編譯它，但可執行文件不會直接運行，除非從終端運行。如果我註釋掉SDL_TFF代碼，它將正常運行。

有誰知道什麼可能導致這個問題？

EDIT2：我測試了看一遍，似乎功能TTF_OpenFont（）引起的問題。只要我不調用這個函數，exe就會正常運行。

已解決！

這是我執行命令行程序的方式：「\ BIN \ MYPROG.EXE」

因此相對文件路徑是不正確，因爲「\ BIN \字體...」是不存在的。由於我沒有實現SDL_LogSetOutputFunction來將日誌寫入文件，並且stdout顯然被抑制了，所以我看不到我必須得到錯誤消息，指出文件未被加載。
