PHP如何调用CMake构建 使用PHP执行CMake的3个示例

<?php

// 示例1：最简单的CMake构建
$sourceDir = '/path/to/your/source';
$buildDir = '/path/to/your/build';

// 确保构建目录存在
if (!is_dir($buildDir)) {
    mkdir($buildDir, 0777, true); // 递归创建目录
}

// 执行CMake配置
$cmakeCommand = "cmake -S {$sourceDir} -B {$buildDir}";
exec($cmakeCommand, $cmakeOutput, $cmakeReturnCode);

if ($cmakeReturnCode !== 0) {
    echo "CMake配置失败：\n";
    echo implode("\n", $cmakeOutput);
    exit(1);
}

// 执行构建
$makeCommand = "cmake --build {$buildDir}";
exec($makeCommand, $makeOutput, $makeReturnCode);

if ($makeReturnCode !== 0) {
    echo "构建失败：\n";
    echo implode("\n", $makeOutput);
    exit(1);
}

echo "构建成功！\n";

?>

<?php

// 示例2：带参数的CMake构建
$sourceDir = '/path/to/your/source';
$buildDir = '/path/to/your/build';
$installPrefix = '/path/to/install';

// 确保构建目录存在
if (!is_dir($buildDir)) {
    mkdir($buildDir, 0777, true); // 递归创建目录
}

// 执行CMake配置，传递参数
$cmakeCommand = "cmake -S {$sourceDir} -B {$buildDir} -DCMAKE_INSTALL_PREFIX={$installPrefix}";
exec($cmakeCommand, $cmakeOutput, $cmakeReturnCode);

if ($cmakeReturnCode !== 0) {
    echo "CMake配置失败：\n";
    echo implode("\n", $cmakeOutput);
    exit(1);
}

// 执行构建
$makeCommand = "cmake --build {$buildDir}";
exec($makeCommand, $makeOutput, $makeReturnCode);

if ($cmakeReturnCode !== 0) {
    echo "构建失败：\n";
    echo implode("\n", $makeOutput);
    exit(1);
}

// 执行安装
$installCommand = "cmake --install {$buildDir}";
exec($installCommand, $installOutput, $installReturnCode);


if ($installReturnCode !== 0) {
    echo "安装失败：\n";
    echo implode("\n", $installOutput);
    exit(1);
}


echo "构建和安装成功！\n";

?>

<?php

// 示例3：错误处理和实时输出
$sourceDir = '/path/to/your/source';
$buildDir = '/path/to/your/build';

// 确保构建目录存在
if (!is_dir($buildDir)) {
    mkdir($buildDir, 0777, true); // 递归创建目录
}

// 执行CMake配置
$cmakeCommand = "cmake -S {$sourceDir} -B {$buildDir}";

$process = proc_open($cmakeCommand,
    [
        0 => ['pipe', 'r'], // stdin
        1 => ['pipe', 'w'], // stdout
        2 => ['pipe', 'w'], // stderr
    ],
    $pipes);

if (is_resource($process)) {
    // 读取输出
    while ($s = fgets($pipes[1])) {
        echo htmlspecialchars($s) . "<br>"; // 输出到浏览器，转义HTML
        flush(); // 强制输出
    }

    while ($s = fgets($pipes[2])) {
        echo "<span style='color:red'>" . htmlspecialchars($s) . "</span><br>"; // 错误信息，红色显示
        flush();
    }


    $return_value = proc_close($process);

    if ($return_value !== 0) {
        echo "<span style='color:red'>CMake配置失败，返回码：".$return_value."</span><br>";
        exit(1);
    } else {
        echo "CMake配置成功！<br>";
    }

    // 执行构建 (类似的方式处理)
    $makeCommand = "cmake --build {$buildDir}";
    $process = proc_open($makeCommand,
        [
            0 => ['pipe', 'r'], // stdin
            1 => ['pipe', 'w'], // stdout
            2 => ['pipe', 'w'], // stderr
        ],
        $pipes);

    if (is_resource($process)) {
        // 读取输出
        while ($s = fgets($pipes[1])) {
            echo htmlspecialchars($s) . "<br>"; // 输出到浏览器，转义HTML
            flush(); // 强制输出
        }

        while ($s = fgets($pipes[2])) {

            flush();
        }


        $return_value = proc_close($process);

        if ($return_value !== 0) {
            echo "<span style='color:red'>构建失败，返回码：".$return_value."</span><br>";
            exit(1);
        } else {
            echo "构建成功！<br>";
        }
    } else {
        echo "<span style='color:red'>无法启动构建进程</span><br>";
        exit(1);
    }



} else {
