OS X Lion上libplist的編譯錯誤：未找到string.h

Question

我正在嘗試為OS X編譯Clementine 。在編譯依賴項的過程中，在libplist-1.3期間，出現一個錯誤，提示編譯器無法找到string.h，assert.h等。然后出現了許多錯誤跟隨。

我不確定為什么會這樣。 我在處理較大的C項目方面經驗不是很豐富，並且希望能發現任何導致這種情況發生的方向。 我肯定已經安裝了Xcode命令行工具，並確保它們是最新的。 此外，標准文件位於/usr/include 。

根據構建說明運行make后的輸出：

cd libplist-1.3/build && PKG_CONFIG_PATH=/Users/dan/projects/sandbox/target/lib/pkgconfig cmake .. -DCMAKE_OSX_ARCHITECTURES=x86_64 -DCMAKE_INSTALL_PREFIX=/Users/dan/projects/sandbox/target -DQT_HEADERS_DIR=/Users/dan/projects/sandbox/target/include/ -DQT_LIBRARY_DIR=/Users/dan/projects/sandbox/target/bin -DENABLE_PYTHON=OFF

.. 還有很多

更新：

除去-j2標志時，libplist會成功構建。 現在我遇到了一個新的錯誤：

      'strdup'; did you mean 'strcmp'?

Answer 1

從評論中部分復制：

嘗試使用make而不是make -j 2編譯。 有時，編譯順序可能會搞砸，而您鏈接到的軟件包站點中明確提到了編譯順序。

至於strdup的問題，該函數在string.h中聲明為C，在cstring為C ++。 如果軟件包構建正確，並且沒有創建重復的標頭，或者嘗試從非標准位置使用標頭，則從完全全新的構建開始可能會解決您的問題。

如果這不起作用，則需要遍歷cmake日志，並在包含路徑中查找目錄，這些目錄中可能包含string.h或cstring ，並且可能會代替默認目錄使用。 如果是這種情況，您一定應該通知維護人員，並弄清楚是否僅刪除這些文件或包含路徑是適當的解決方法。

除此之外，我認為您還必須通過他們的網站與軟件包維護者聯系。

祝好運！
