c语言 - Littlecms - 编译"undefined reference to `cmsOpenProfileFromFile' "过程中出错

Question

请帮助我使用LittleCMS框架-我收到"对`cmsOpenProfileFromFile'的未定义引用">

我做了：

1) 下载自https://github.com/mm2/Little-CMS文件lcms2.h

2) 已下载https://sourceforge.net/projects/lcms/and试着像文档中写的那样安装它(下载了tar文件，取消了tar，运行了

./configure make sudo make install

3) 尝试实现教程中的示例：

#include "lcms2.h"
int main(void)
{
cmsHPROFILE hInProfile, hOutProfile;
cmsHTRANSFORM hTransform;
hInProfile = cmsOpenProfileFromFile("AdobeRGB1998.icc", "r");
hOutProfile = cmsOpenProfileFromFile("WebCoatedSWOP2006Grade5.icc", "r");
hTransform = cmsCreateTransform(hInProfile, TYPE_BGR_8, hOutProfile, TYPE_BGR_8, INTENT_PERCEPTUAL, 0);
cmsCloseProfile(hInProfile);
cmsCloseProfile(hOutProfile);
return 0;
}

在运行"make"之后，我收到了"对`cmsOpenProfileFromFile'的未定义引用"。

我想我必须安装一些库(我必须在makefile中添加类似的东西——L/opt/local/lib64-llcms2，或者将其添加到clang…)，但我已经阅读了数千字节的网页，没有人告诉我如何从头开始——库不会出现在/opt/local/lib64或/opt/local/lib文件夹中(我在任何目录中都找不到lcms2)。

我的IDE是：CS50 IDE，Linux版本4.9.17-c9(root@30db80bfe262)(gcc版本4.9.2(Debian 4.9.2-10))。

我对编程很陌生，所以请屈尊俯就。请帮我解决和实现小CMS。

更新：3种类型的汇编：

1) 命令提示符(内部IDE的makefile，没有我的makefile)：

~/workspace/cmyk/ $ make cmyk

2) Makefile1(带有叮当声)：

CC = clang
CFLAGS = -ggdb3 -O0 -Qunused-arguments -std=c99 -Wall -Werror
EXE = cmyk
HDRS = lcms2.h
LIBS =
SRCS = cmyk.c
OBJS = $(SRCS:.c=.o)
$(EXE): $(OBJS) $(HDRS) Makefile
$(CC) $(CFLAGS) -o $@ $(OBJS) $(LIBS)
$(OBJS): $(HDRS) Makefile
clean:
rm -f core $(EXE) *.o

输出：

~/workspace/cmyk/ $ make cmyk
clang -ggdb3 -O0 -Qunused-arguments -std=c99 -Wall -Werror   -c -o cmyk.o cmyk.c
clang -ggdb3 -O0 -Qunused-arguments -std=c99 -Wall -Werror -o cmyk cmyk.o

/home/ubuntu/workspace/cmyk/cmyk.c:15: undefined reference to `cmsCloseProfile'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [cmyk] Error 1

3) Makefile2:

iEdit: cmyk.o
gcc $^ -o $@ -std=c99
.c.o:
gcc -c $< -std=c99
cmyk.o:     lcms2.h

输出：

~/workspace/cmyk/ $ make cmyk
gcc -c cmyk.c -std=c99
clang   cmyk.o  -lcrypt -lcs50 -lm -o cmyk
cmyk.o: In function `main':

clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [cmyk] Error 1

Answer 1

解决方案是使用其他IDE-CS50 IDE不允许安装额外的库。我安装了VirtualBox，安装了xubuntu，安装了lib，在Makefile中添加了-L/usr/local/lib -llcms2，我的程序编译得没有错误。
