Question

成功编译代码后。链接过程开始，在那里出现问题。

我检查了main函数，它存在于代码中，检查了链接sdl的cmake，我想它是下降的。所有库都是静态的，我确实注意到Gradle在链接过程中使用crtbegin_dynamic，不应该使用crtbegin_static吗？

主要功能：

int main(int argc, char **argv)
{
char commandLine[MAX_STRING_CHARS] = { 0 };

Sys_PlatformInit();

// Set the initial time base
Sys_Milliseconds();

#ifdef __APPLE__
// This is passed if we are launched by double-clicking
if (argc >= 2 && Q_strncmp(argv[1], "-psn", 4) == 0)
{
    argc = 1;
}
#endif

Sys_ParseArgs(argc, argv);

#if defined(__APPLE__) && !defined(DEDICATED)
// argv[0] would be /Users/seth/etlegacy/etl.app/Contents/MacOS
// But on OS X we want to pretend the binary path is the .app's parent
// So that way the base folder is right next to the .app allowing
{
    char     parentdir[1024];
    CFURLRef url = CFBundleCopyBundleURL(CFBundleGetMainBundle());
    if (!url)
    {
        Sys_Dialog(DT_ERROR, "A CFURL for the app bundle could not be found.", "Can't set Sys_SetBinaryPath");
        Sys_Exit(EXIT_FAILURE);
    }

    CFURLRef url2 = CFURLCreateCopyDeletingLastPathComponent(0, url);
    if (!url2 || !CFURLGetFileSystemRepresentation(url2, 1, (UInt8 *)parentdir, 1024))
    {
        Sys_Dialog(DT_ERROR, "CFURLGetFileSystemRepresentation returned an error when finding the app bundle's parent directory.", "Can't set Sys_SetBinaryPath");
        Sys_Exit(EXIT_FAILURE);
    }

    Sys_SetBinaryPath(parentdir);

    CFRelease(url);
    CFRelease(url2);
}
#else
Sys_SetBinaryPath(Sys_Dirname(argv[0]));
#endif

Sys_SetDefaultInstallPath(DEFAULT_BASEDIR); // Sys_BinaryPath() by default

// Concatenate the command line for passing to Com_Init
Sys_BuildCommandLine(argc, argv, commandLine, sizeof(commandLine));

Com_Init(commandLine);
NET_Init();

Sys_SetUpConsoleAndSignals();

#ifdef _WIN32

#ifndef DEDICATED
if (com_viewlog->integer)
{
    Sys_ShowConsoleWindow(1, qfalse);
}
#endif

Sys_Splash(qfalse);

{
    char cwd[MAX_OSPATH];
    _getcwd(cwd, sizeof(cwd));
    Com_Printf("Working directory: %s\n", cwd);
}

// hide the early console since we've reached the point where we
// have a working graphics subsystems
#ifndef LEGACY_DEBUG
if (!com_dedicated->integer && !com_viewlog->integer)
{
    Sys_ShowConsoleWindow(0, qfalse);
}
#endif

#endif

Sys_GameLoop();

return EXIT_SUCCESS;
}

cmake文件的一部分：

我想使其正确链接，以便继续进行构建。

Answer 1

包含 main（）的C文件应该是 etl 目标的来源之一，而不是库之一。

Answer 2

因此，在修复了所有这些未定义的参考错误之后，我确实碰壁了，仍然有一些要处理，但是我不确定如何处理。

有2个文件tr_init.c和tr_shade.c正在/正在抛出这些错误我确实在tr_init.c

中修复了这些问题

tr_init.c

之前

if (qglLockArraysEXT)
{
primitives = 2;
}

Ren_Print("compiled vertex arrays: %s\n", enablestrings[qglLockArraysEXT != 0]);

非洲人

if (&qglLockArraysEXT)
{
primitives = 2;
}

Ren_Print("compiled vertex arrays: %s\n", enablestrings[&qglLockArraysEXT != 0]);

tr_shade.c

if (qglLockArraysEXT)
{
qglLockArraysEXT(0, input->numVertexes);
Ren_LogComment("glLockArraysEXT\n");
}

if (qglUnlockArraysEXT)
{
qglUnlockArraysEXT();
Ren_LogComment("glUnlockArraysEXT\n");
}

这是错误

最重要的一行没有响应那些引用第一个参考点指向文件中的201行

Android Gradle构建错误：未定义对“ main”的引用

主要功能：

cmake文件的一部分：

这是构建日志：
