hello everyone,

i have a program that uses pcap and mysql libraries.

i have a makefile;

Code:

all:
	LIBS=-L/usr/include/mysql -lmysqlclient -lpcap
	gcc -Wall -pedantic $(LIBS) -o main main.c

when i run make command it gives the error

Code:

LIBS=-L/usr/include/mysql -lmysqlclient -lpcap
/bin/sh: -lmysqlclient: command not found
make: *** [all] Error 127

but when i was using only mysql library ;

Code:

gcc -o main  -L/usr/include/mysql -lmysqlclient main.c

was working.

now how can i compile the source code that uses two libraries?

In Makefiles, inside rules tab-indented sections are interpreted like shell commands, and this can include a var=value prefix to a command.

Instead, move the assignment to the LIBS variable out of the rule:

Code:

LIBS = -L/usr/include/mysql -lmysqlclient -lpcap

all:
	gcc -Wall -pedantic $(LIBS) -o main main.c
