我收到错误 #include <czmq.h>运行程序时丢失 [英] I get error #include &lt;czmq.h&gt; missing when running program

问题描述

过去 4 天我一直在尝试让 Zeromq 在我的 Windows 机器上运行，但似乎没有任何进展.

I am trying from past 4 days to get Zeromq working on my Windows machine but nothings seems to go my way.

我按照给定的步骤解决了一些依赖性问题.

I followed given steps and solved few dependcy issues.

我已经成功构建了 libzmq、czmq、libsodium.

I have build libzmq,czmq,libsodium successfully.

我使用 cmake 3.12 进行配置，使用 VS2015 SDK 8.1 构建解决方案.

I used cmake 3.12 to configure and VS2015 SDK 8.1 to build solution.

我能够运行 czmq_selftest.exe，但是它因为一些事情而失败，这是不同的问题.

I was able to run czmq_selftest.exe however it failed for few things and thats different issue.

但是当我尝试运行基本程序 myapp.c

But when I try to run basic program myapp.c

#include <czmq.h>
int main (void) {
 zsock_t *publisher = zsock_new (ZMQ_PUB);
 zsock_set_curve_server (publisher, true);
 puts ("Hello, Curve!");
 zsock_destroy(&publisher);
 return 0;
}

我看到这个缺少库的问题，我尝试了给定的链接方法-

I see this missing library issue , I tried given link method-

 gcc myapp.c -o myapp -lczmq -lzmq

但没有任何效果，如果有人能提供一些解决方案，那将非常有帮助.

But nothing is working it would be really helpful if someone can provide some solution.

这是其他信息-

OS - Windows 10
Cmake - 3.13.2
Visual Studio 2015, SDK 8.1
libzmq 4.3.0
czmq 4.1.1

更多信息-

我的系统-

C:\Users\P\go\src\github.com\zeromq\czmq\include

包含所有库.

我的程序在 -

C:\Users\P\go\src\github.com\zeromq\czmq\examples\security

谢谢

推荐答案

编译器无法自行跟踪用户可能已安装在系统上的所有库.您必须告诉编译器在哪里可以找到头文件或链接器库等内容.

The compiler can't keep track of all libraries that a user might have installed on a system by itself. You have to tell the compiler where it can find things like header files or linker-libraries.

要告诉编译器向用于搜索头文件的列表添加路径，请使用 -I(大写 i)选项.

To tell the compiler to add a path to the list it uses for searching for header file, use the -I (upper-case i) option.

要告诉链接器向用于搜索链接器库的列表添加路径，请使用 -L 选项.

To tell the linker to add a path to the list it uses to search for linker-libraries use the -L option.

考虑到您在问题和评论中提到的路径，您需要添加 -I../../include 和 -L../../Debug>.

Considering the paths you mention in your question and comments you need to add both -I../../include and -L../../Debug.

也就是说，您的完整命令应该类似于

That is, your complete command should look something like

gcc myapp.c -o myapp -I../../include -L../../Debug -lczmq -lzmq

当然，这需要你在目录 C:\Users\P\go\src\github.com\zeromq\czmq\examples\security 中，如你所说.

Of course, that requires your to be in the directory C:\Users\P\go\src\github.com\zeromq\czmq\examples\security as you say.
