make 命令在 MacOS Big Sur - 11.5.2 上不起作用

Question

我正在尝试在 Swift 项目中使用 C 库的示例。下面是参考link

https://medium.com/bumble-tech/bundling-c-library-in-swift-framework-3d9dae950774

C 库文件link https://sourceforge.net/projects/giflib/files/

按照教程 link 中的说明，解压缩代码并通过终端转到文件夹并使用 make 命令，work.I 不会尝试在 MAC 上执行此操作oS 大苏尔。下面是错误

**ABC-MacBook-Pro:giflib-5.2.1 abc$ make**

cc -std=gnu99 -fPIC -Wall -Wno-format-truncation -O2 -shared  -Wl,-install_name -Wl,libutil.so.7 -o libutil.so qprintf.o quantize.o getarg.o

Undefined symbols for architecture x86_64:
  "_GifErrorString", referenced from:
      _PrintGifError in qprintf.o

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

make: *** [libutil.so] Error 1

Answer 1

改变

USOURCES = qprintf.c quantize.c getarg.c

至此

USOURCES = qprintf.c quantize.c getarg.c gif_err.c

里面 Makefile。另外，更改这些行：

$(CC) $(CFLAGS) -shared $(LDFLAGS) -Wl,-soname -Wl,libgif.so.$(LIBMAJOR) -o libgif.so $(OBJECTS)
...
...
$(CC) $(CFLAGS) -shared $(LDFLAGS) -Wl,-soname -Wl,libutil.so.$(LIBMAJOR) -o libutil.so $(UOBJECTS)

到

$(CC) $(CFLAGS) -shared $(LDFLAGS) -Wl,-install_name -Wl,libgif.so.$(LIBMAJOR) -o libgif.so $(OBJECTS)
...
...
$(CC) $(CFLAGS) -shared $(LDFLAGS) -Wl,-install_name -Wl,libutil.so.$(LIBMAJOR) -o libutil.so $(UOBJECTS)

会完成工作

> make
cc -std=gnu99 -fPIC -Wall -Wno-format-truncation -O2   -c -o dgif_lib.o dgif_lib.c
warning: unknown warning option '-Wno-format-truncation' [-Wunknown-warning-option]
...
...
cc -std=gnu99 -fPIC -Wall -Wno-format-truncation -O2    gifwedge.c libgif.a libutil.a  libgif.a -lm -o gifwedge
warning: unknown warning option '-Wno-format-truncation' [-Wunknown-warning-option]

为了跳过xmlto执行，移除

#       $(MAKE) -C doc
