ZLIB 的编译问题 [英] Compilation problems with ZLIB

问题描述

我想编译一些第三方软件，但显然我遇到了 ZLIB 的问题.

I would like to compile some third-party software but I encounter a problem with ZLIB apparently.

见下文:

 $sudo make
    gcc -Wall -pedantic -DVERSION=1.2 -lz -O3 sliding.o trim_single.o trim_paired.o sickle.o -o sickle
    trim_paired.o: In function `ks_getuntil':
    trim_paired.c:(.text+0x78): undefined reference to `gzread'
    trim_paired.o: In function `kseq_read':
    trim_paired.c:(.text+0x48d): undefined reference to `gzread'
    trim_paired.c:(.text+0x4dc): undefined reference to `gzread'
    trim_paired.c:(.text+0x60a): undefined reference to `gzread'
    trim_paired.c:(.text+0x687): undefined reference to `gzread'
    trim_paired.o: In function `paired_main':
    trim_paired.c:(.text+0xc62): undefined reference to `gzopen'
    trim_paired.c:(.text+0xc83): undefined reference to `gzopen'
    trim_paired.c:(.text+0x1142): undefined reference to `gzclose'
    trim_paired.c:(.text+0x114f): undefined reference to `gzclose'
    trim_single.o: In function `ks_getuntil':
    trim_single.c:(.text+0x78): undefined reference to `gzread'
    trim_single.o: In function `single_main':
    trim_single.c:(.text+0x688): undefined reference to `gzopen'
    trim_single.c:(.text+0x8ad): undefined reference to `gzread'
    trim_single.c:(.text+0x8f5): undefined reference to `gzread'
    trim_single.c:(.text+0xb11): undefined reference to `gzread'
    trim_single.c:(.text+0xb96): undefined reference to `gzread'
    trim_single.c:(.text+0xc58): undefined reference to `gzclose'
    collect2: ld returned 1 exit status
    make: *** [build] Error 1

我使用的是 Ubuntu，我确实在/usr/local/lib 中安装了 ZLIB 1.2.6

I am using Ubuntu and I did install ZLIB 1.2.6 in /usr/local/lib

这是生成文件:

PROGRAM_NAME = sickle
VERSION = 1.2
CC = gcc
CFLAGS = -Wall -pedantic -DVERSION=$(VERSION)
DEBUG = -g
OPT = -O3
ARCHIVE = $(PROGRAM_NAME)_$(VERSION)
LDFLAGS = -lz
SDIR = src

.PHONY: clean default build distclean dist debug

default: build

sliding.o: $(SDIR)/sliding.c $(SDIR)/kseq.h $(SDIR)/sickle.h
    $(CC) $(CFLAGS) $(OPT) -c $(SDIR)/$*.c

trim_single.o: $(SDIR)/trim_single.c $(SDIR)/sickle.h $(SDIR)/kseq.h
    $(CC) $(CFLAGS) $(OPT) -c $(SDIR)/$*.c

trim_paired.o: $(SDIR)/trim_paired.c $(SDIR)/sickle.h $(SDIR)/kseq.h
    $(CC) $(CFLAGS) $(OPT) -c $(SDIR)/$*.c

sickle.o: $(SDIR)/sickle.c $(SDIR)/sickle.h
    $(CC) $(CFLAGS) $(OPT) -c $(SDIR)/$*.c

clean:
    rm -rf *.o $(SDIR)/*.gch ./sickle

distclean: clean
    rm -rf *.tar.gz

dist:
    tar -zcf $(ARCHIVE).tar.gz src Makefile

build: sliding.o trim_single.o trim_paired.o sickle.o
    $(CC) $(CFLAGS) $(LDFLAGS) $(OPT) $? -o sickle

debug:
    $(MAKE) build "CFLAGS=-Wall -pedantic -g -DDEBUG"

感谢任何帮助;)

谢谢

推荐答案

我自己找到了答案！它的工作原理是改变:

I found the answer myself ! It works by changing:

$(CC) $(CFLAGS) $(LDFLAGS) $(OPT) $? -o sickle

到

$(CC) $(CFLAGS)  $(OPT) $? -o sickle $(LDFLAGS)

-lz 选项必须在最后.

the -lz option has to be at the end.
