我是使用CMake的新手(對於C++來說,對於Makefiles,C,&來說是相當新的)。我的任務是將我們當前的構建系統更改爲使用CMake生成Makefiles並編譯我們的代碼的系統。我很難破譯CMake報告的錯誤,並且沒有運氣搜索這個網站或任何sute。如果這個問題已經在其他地方得到解答,請直接告訴我,我會提前通知你。解密CMake錯誤

我曾試圖發佈顯示我們當前文件結構的破壞的形象,但我沒有信譽點張貼圖片...

下面是我在同時運行接收錯誤cmake。 & 使

「expatfiles.txt只是列出了expat所需的源文件」不這樣做。 CMake無法檢測到這個文件的變化,所以如果你修改它,cmake將不會自動構建新添加的文件。只需在相應的CMakeLists.txt中列出它們即可。 – SirDarius

您看到的錯誤是'make'錯誤,而不是'cmake'錯誤,這些錯誤看起來像來自編譯器。你可能想檢查你的源代碼。 – SethMMorton

此特定錯誤是不是因爲CMake的。反而看到這一行:

/home/projects/OMAP-L137/timesys/factory-current/build_armv5l-timesys-linux- uclibcgnueabi/DSPLink-1_65_01/DSPLink-1_65_01/dsplink/gpp/inc/usr/linkcfgdefs.h:824:37: error: 'MAX_DSPS' was not declared in this scope`` 

問題是缺少的符號MAX_DSPS。在源代碼樹中執行遞歸grep,並查看該應該來自哪裏。它很可能是一個在頭文件中定義的宏(或全局變量),您未包含它,或者它可能是您需要在編譯時通過CMakeLists.txt文件提供的宏(請參閱文檔: add_definitions關於如何在CMake中執行它)
