我正在将 Raspberry Pi 上的工作应用程序迁移到最新的 OS Bookworm。
在 make 时，出现以下错误：
make
clang++ -lpthread -L/usr/local/lib –lreadline -lcurl -lpigpio -o build/cpssuper build/common.cpp.o build/gpio.cpp.o build/mutex.cpp.o build/namedpipe.cpp.o build/console.cpp.o build/pcs-api-task.cpp.o build/main.cpp.o build/utils.cpp.o build/datetime.cpp.o
clang: error: no such file or directory: '–lreadline'
make: *** [Makefile:40: build/cpssuper] Error 1
我之前使用的是readline7，但这无法安装，所以我必须安装readline8。
sudo apt-get install libreadline8 libreadline-dev
安装成功，如果我运行 apt-cache，我会得到以下信息：

问题已在评论中得到解答，但只需将信息放入正确的框中即可：
问题是
Makefile–lreadline检查这一点的一种方法是将该线穿过
hexdump -C$ echo 'LDFLAGS = -lpthread -L/usr/local/lib –lreadline -lcurl -lpigpio' | hexdump -C
