MATLAB：缺少對MEX編譯框架 - 未定義的符號體系結構x86_64的

Question

我一直在試圖讓我的頭周圍的一些錯誤，編譯C編寫的MATLAB功能（在Mac OS X），當我得到。函數msound由我的大學爲Windows和Linux預編譯，並且是有關錄製和播放音頻的其他功能的基礎。由於我是Mac用戶，我認爲將其編譯爲Mac版本也是非常合適的。

從源代碼和Linux版的編譯器的功能我想的編譯器指令反向工程一個Mac版本，但我不斷收到導致一個失敗的編譯錯誤。這裏是我放在一起作爲編譯器的功能至今：

function compile_msound_unix 

disp('Building msound ...') 

szOptions = ''; 
szDefines = ''; 
szPaths = ''; 
szFiles = ''; 
szLibs = ''; 

szOptions = sprintf('%s %s', szOptions, '-output msound'  ); 
szOptions = sprintf('%s %s', szOptions, '-largeArrayDims'  ); 

% Add main file. 
szFiles = addFile(szFiles, 'msound.c'); 

% Add basic PortAudio include paths and files. 
szPaths = addPath(szPaths, 'portaudio/include'      ); 
szPaths = addPath(szPaths, 'portaudio/src/common'      ); 
szPaths = addPath(szPaths, 'portaudio/src/os/unix'     ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_allocation.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_converters.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_cpuload.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_debugprint.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_dither.c'   ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_front.c'   ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_process.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_ringbuffer.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_skeleton.c'  ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_stream.c'   ); 
szFiles = addFile(szFiles, 'portaudio/src/common/pa_trace.c'   ); 
% Host 
szFiles = addFile(szFiles, 'portaudio/src/os/unix/pa_unix_hostapis.c' ); 
szFiles = addFile(szFiles, 'portaudio/src/os/unix/pa_unix_util.c'  ); 

% Add PortAudio path for: Apple Core Audio API 
disp(' Using ''Apple Core Audio API'' ...') 

% Defines 
szDefines = addDefine(szDefines, 'PA_USE_COREAUDIO'); 
szDefines = addDefine(szDefines, '__MACOSX_CORE__'); 
% PortAudio 
szPaths = addPath(szPaths, 'portaudio/src/hostapi/coreaudio'); 
szFiles = addFile(szFiles, 'portaudio/src/hostapi/coreaudio/pa_mac_core_blocking.c'); 
szFiles = addFile(szFiles, 'portaudio/src/hostapi/coreaudio/pa_mac_core_utilities.c'); 
szFiles = addFile(szFiles, 'portaudio/src/hostapi/coreaudio/pa_mac_core.c'); 
% Libs 
% szLibs = addLib (szLibs , '/full/path/to/library?'); 

% Build msound MEX-file using default compiler. 
eval([ 'mex', szOptions, szDefines, szPaths, szFiles, szLibs ]); 

function szCmd = addFile (szCmd, szFile) 
    szCmd = sprintf('%s "%s"' , szCmd, szFile); 
function szCmd = addPath (szCmd, szPath) 
    szCmd = sprintf('%s "-I%s"', szCmd, szPath); 
function szCmd = addDefine(szCmd, szName) 
    szCmd = sprintf('%s "-D%s"', szCmd, szName); 
function szCmd = addLib (szCmd, szLib ) 
    szCmd = sprintf('%s "-l%s"', szCmd, szLib ); 
function szCmd = addLibPath(szCmd, szPath) 
    szCmd = sprintf('%s "-L%s"', szCmd, szPath) 

我已經消除了其他一些錯誤，但現在我只能堅持以下MATLAB控制檯輸出：

的主要問題似乎是Undefined symbols for architecture x86_64。我做了一些研究，現在我知道一些框架可能會丟失。但我對這種編程非常陌生（並且在Mac上編譯），我可以使用一些幫助。

我嘗試編譯功能是基於支持在Mac上的CoreAudio的音頻PortAudio-I/O。正如你在我的編譯器函數中看到的，我已經包含了必要的PortAudio文件，但是我仍然缺少相應的庫/框架。我已經試圖爲他們提供如下線路：

szLibs = addLib (szLibs , '/System/Library/Frameworks/CoreAudio.framework'); 

但是沒有任何成功。我真的希望你們有想法如何讓這個運行。我正在使用Mac OS X 10.7.3 Lion，我安裝了Xcode並正在運行gcc-4.2。 MATLAB版本是2011A（v7.12）

在此先感謝1月

Answer 1

Heureka！我終於找到了它自己：既然我只是拍了很多的代碼從Linux的msound MEX編譯功能，問題是neccesary框架是如何在鏈接事實證明了" ... "（雙引號。 ）的路徑和文件是錯誤的，它的工作，只有框架，實際上需要他們，因爲他們融洽相處，從而GCC通過。我將它們從addFile,addPath等中刪除，最後所有文件都被識別並鏈接了框架，以便所有丟失的符號都消失。我的頓悟主要是由this Stackoverflow question發起的，特別是它的正確答案。

在利益的情況下，這裏是全工作編譯器功能：

function compile_msound_mac 

bOldMexApi = false; 

disp('Building msound ...') 

szOptions = ''; 
szDefines = ''; 
szPaths = ''; 
szFiles = ''; 
szFrameworks = 'LDFLAGS="\$LDFLAGS'; 

szOptions = sprintf('%s %s', szOptions, '-output msound'  ); 

% Use the old MATLAB C API on newer MATLAB versions. 
if(~verLessThan('matlab','7.3')) 
    if(bOldMexApi) 
     % Use backward compatible old MATLAB C API 
     szOptions = sprintf('%s %s', szOptions, '-compatibleArrayDims'); 
    else 
     szOptions = sprintf('%s %s', szOptions, '-largeArrayDims'  ); 
    end 
end 

% Add main file. 
szFiles = addFile(szFiles, 'msound.c'); 

% Add basic PortAudio include paths and files. 
szPaths = addPath(szPaths, 'portaudio/include'      );
