This article will explain in detail the reasons for the failure of the link library in linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

I've come across several situations:

1. Failed to add path. In makefile, I added the path to the library, either absolute or relative, and failed. What on earth caused the failure of-L? After that, I add the library path in the bashrc file, and after that, I compile it.

two。 This is the problem we encountered today. I wrote a makefile.

All: $(TARGET)

.PHONY: all

(TARGET): $(SRC)

Gmail + $(LIB) $(INCLUDE)-o $@ $^-pthread-lm

.PHONY: clean

Clean:

@ rm-r $(TARGET)

At compile time, undefined references to the function are displayed. I checked it carefully and there was no mistake. After repeated verification, it is the command line problem.

Correct format: LIB + $(INCLUDE)-o $@ $^-pthread-lm $(LIB)
