为给定库生成 gcc 的编译器/链接器标志

Question

Problem

Is there a way I can generate linker/compiler flags for function libraries, given one or more source files?

Software specifications:

• Operating System: Ubuntu 20.04 LTS x86_64
• Kernel: 5.11.0-27-generic

There's a handy tool you can use to generate compiler/linker flags for your code. It's called pkg-config , and you can use it like so:

gcc file.c $(pkg-config --cflags <library>) $(pkg-config --libs <library>)

I'd recommend defining a variable containing all of your dependencies, then using a shell script or other means to generate the pkg-config output for that library.
