Re: error with 4.0.9 "c" API or user

how-to-repeat:

compile a c program use mysqlclient 4.0.9.
Below is the makefile and output from running make

Makefile:
CC = gcc
INCLUDES = -I/usr/include/mysql
LIBS = -L/usr/lib/mysql -lmysqlclient -lm
all: listener
main.o: main.c common.h
$(CC) -c $(INCLUDES) main.c
common.o: common.c common.h
$(CC) -c $(INCLUDES) common.c
listener: main.o common.o
$(CC) -o listener main.o common.o $(LIBS)
clean:
rm -f listener main.o common.o


I am getting the following message when submitting the following:

[sam@linux sam]$ make

gcc -o listener main.o common.o -L/usr/lib/mysql -lmysqlclient -lm
/usr/lib/mysql/libmysqlclient.a(my_compress.o):
In function `my_uncompress': my_compress.o(.text+0xaa):undefined
reference to `uncompress'
/usr/lib/mysql/libmysqlclient.a(my_compress.o):
In function `my_compress_alloc': my_compress.o(.text+0x13c): undefined
reference to `compress'
collect2: ld returned 1 exit status make: *** [listener] Error 1

Please advise

sam

Add -lz to your link line after -lmysqlclient. Your system is
apparently one where libraries cannot tell the linker what other
libraries they depend on, so you have to do it yourself.
