无法使用maven-nar插件生成C/C++项目

Question

我正在尝试用maven，cygwin和gcc在windows7上建立一个带有空函数(.c和.h文件)的简单项目。以下是有关我的环境的详细信息：

Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 22:51:28+0900)
Maven home: C:\Program Files\apache-maven-3.0.5
Java version: 1.6.0_37, vendor: Sun Microsystems Inc.
Java home: C:\Progra~1\Java\jdk1.6.0_37\jre
Default locale: ko_KR, platform encoding: MS949
OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"
gcc (GCC) 4.5.3

当我尝试使用maven-nar插件构建时，我得到以下错误：

$ mvn clean package

我有谷歌的，这似乎与maven找不到gcc编译器有关。

Cannot deduce version number from: -> [Help 1]

mvn命令的输出还表明，maven正在尝试使用我的机器上不可用的msvc构建我的项目。

[INFO] Using AOL: x86-Windows-msvc

我将gcc编译器放在path等文件中，并尝试遵循this very old thread中建议的一些步骤。

有人知道如何克服这个问题吗？如果我在错误的论坛，谁能给我指给我正确的论坛？

是的，该错误是由于命令行工具在路径上不可用而导致的。然而，在本例中，由于您的AOL是x86-Windows-msvc，因此相关的命令行工具是link，而不是gcc。(您可以在the source code中看到此内容。)

当然，您根本不想使用MSVC编译器，所以无论如何都不应该在路径中使用link。要使用gcc，您需要在maven-nar-plugin配置的POM中对其进行配置。下面是一个示例配置(来自this project，您当然需要根据需要进行调整)：

<configuration>
    <c>
        <name>gcc</name>
        <includes>
            <include>**/*.c</include>
        </includes>
        <options>
            <option>-I${JAVA_HOME}/include</option>
            <option>${java.os.include}</option>
            <option>${stack.protector.option}</option>
            <option>${architecture.option}</option>
            <option>${subsystem.option}</option>
            <option>${debug.option}</option>
        </options>
    </c>
    <linker>
        <name>gcc</name>
        <options>
            <option>${architecture.option}</option>
            <option>${subsystem.option}</option>
        </options>
        <sysLibs>
            <sysLib>
                <name>${libdl.name}</name>
            </sysLib>
        </sysLibs>
    </linker>
    <libraries>
        <library>
            <type>executable</type>
            <!-- <run>true</run> -->
            <subSystem>gui</subSystem>
        </library>
    </libraries>
</configuration>
