不使用clang管理链接库

我想用和构建一个Web服务器

目前的项目结构是

Makefile

/src
  /main.c

/deps
  /libuv (git clone of libuv)
  /http-parser (git clone of http-parser)

在main.c中，我定义了以下内容：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "uv.h"
#include "http_parser.h"

当编译器尝试链接http_解析器时会发生这种情况

make -C deps/libuv libuv.a
make[1]: `libuv.a' is up to date.
make -C deps/http-parser http_parser.o
make[1]: `http_parser.o' is up to date.
cc src/main.c -o main.out deps/libuv/libuv.a deps/http-parser/http_parser.o
src/main.c:5:10: fatal error: 'http_parser.h' file not found
#include "http_parser.h"
         ^
1 error generated.
make: *** [main] Error 1

当我从includes和Makefile中删除http_解析器时，我会得到一个奇怪的libuv构建错误：

从昨天起我就一直在这个问题上纠缠不休，完全失去了希望

生成文件的当前状态：

LDFLAGS = -Ldeps/libuv
INCLFLAGS = -Ideps/http-parser

    $(CC) src/main.c $(INCLFLAGS) -o main.o deps/libuv/libuv.a deps/http-parser/http_parser.o $(LDFLAGS)

libuv.a:

clean:
    rm deps/libuv/libuv.a
    rm deps/http-parser/http_parser.o

我怀疑http\u parser.h与main.c不在同一目录中。要么将该文件复制到那里，要么最好更新包含路径

HTTP_PARSER_INCLUDE= -I/home/wherever/http_parser

main: libuv http-parser
    $(CC) src/main.c -o main.out $(HTTP_PARSER_INCLUDE) deps/libuv/libuv.a deps/http-parser/http_parser.o $(LDFLAGS)

删除http_parser.h时出现的另一个错误可能是由于没有从一开始就构建干净而产生的噪音。上面声明的“main”规则将生成“main.out”而不是“main”。这也可能与Make试图从无到有地构建一些东西有关

更新-您需要将

-framework CoreFoundation

添加到命令行以删除链接器错误。

关于include标志，您似乎是对的。http_解析器不再有错误，但链接libuv的错误仍然存在。我已经添加了更新的Makefile，它现在使用与输出文件相同的规则名称您在Mac上，对吗？您需要将“-framework CoreFoundation”添加到您的命令行中。谢谢，这几乎就是它。我添加了您的标志，但仍有一些未定义的符号。因此，我查看了libuv makefile以了解更多的框架，并在这里找到了它们：现在它可以工作了。谢谢！
