基本上我正在嘗試使用 OpenGL 和 SDL 構建游戲引擎。我使用 makefile 來編譯它，但我得到一個錯誤。在我重新組織我的檔案夾結構并將 src 檔案夾包含到包含路徑后，錯誤開始出現，因此我可以使用絕對路徑訪問它們。例如Renderer/Camera.h，而不是../Renderer/Camera.h.
當我嘗試編譯我的專案時，出現此錯誤：
C:/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find src: Permission denied
collect2.exe: error: ld returned 1 exit status
mingw32-make: *** [Makefile:57: build] Error 1
這是我的makefile

DEBUG_MACRO:=-D DEBUG
OS_MACRO:=-D

SRC := src
INCLUDE := -Isrc -Iinclude
LIB := lib
#Check the OS
ifeq ($(OS),Windows_NT)

OS_MACRO =__WINDOWS__
SOURCES := $(wildcard $(SRC)/***/*.cpp) $(wildcard $(INCLUDE)/***/*.cpp) $(wildcard $(SRC))

# the build target executable
EXECUTABLE := game

showfiles:

這是我的專案檔案夾結構
uj5u.com熱心網友回復：
這是無效的：
SOURCES := $(wildcard $(SRC)/***/*.cpp) $(wildcard $(INCLUDE)/***/*.cpp) $(wildcard $(SRC))
我不知道你從哪里得到通配符語法，但它并沒有按照你的想法做。 ***與*GNU make 使用的標準 glob 語法相同。您是否真的希望.cpp在您的目錄中找到檔案$(INCLUDE)？那會很奇怪。
正如 ssbssa 所指出的那樣，問題在于$(wildcard $(SRC))它將擴展到$(wildcard src)is just src，因此您試圖將一個目錄添加到您的鏈接行，這是非法的并且聯結器會抱怨。
