構建XPCOM Mozilla的樣品組分

我試圖建立可以在這裏XPCOM組件： http://mxr.mozilla.org/mozilla-central/source/xpcom/sample/構建XPCOM Mozilla的樣品組分

我想用我自己的Makefile來編譯它，所以這個組件可以從Mozilla的全部來源中分離。

因此，這裏是我的文件樹：

這裏是我做出的生成文件：我想在Windows下用Cygwin來構建它

CXX = c++ 
CPPFLAGS +=  -fno-rtti    \ 
     -fno-exceptions  \ 
     -shared 

# Change this to point at your Gecko SDK directory. 
GECKO_SDK_PATH = /cygdrive/c/dev/greenchallenge/xulrunner-sdk-9.0.1 

# GCC only define which allows us to not have to #include mozilla-config 
# in every .cpp file. If your not using GCC remove this line and add 
# #include "mozilla-config.h" to each of your .cpp files. 
GECKO_CONFIG_INCLUDE = -include mozilla-config.h 

GECKO_DEFINES = -DXPCOM_GLUE -DXP_WIN 

GECKO_INCLUDES = -I $(GECKO_SDK_PATH)/include 

GECKO_LDFLAGS = -L $(GECKO_SDK_PATH)/lib -lxpcomglue \ 
       -lnspr4  \ 
       -lplds4  

FILES = nsSample.cpp nsSampleModule.cpp 

TARGET = sample.dll 

build: 
    $(CXX) -Wall -Os -o $(TARGET) $(GECKO_CONFIG_INCLUDE) $(GECKO_DEFINES) $(GECKO_INCLUDES) $(GECKO_LDFLAGS) $(CPPFLAGS) $(CXXFLAGS) $(FILES) 
    chmod +x $(TARGET) 
    strip $(TARGET) 

clean: 
    rm $(TARGET)

（用gcc & G ++安裝）。

編譯時，我得到茨艾倫錯誤，以及研究一些小時後，我還是不明白他們：

這是因爲如果有一個在Mozilla的代碼中的錯誤？我究竟做錯了什麼？

謝謝！

弗拉基米爾是正確的一點：nsISample。彙編中缺少h。

但是，創建此文件不會解決主要問題：無法使用GCC for Windows編譯Mozilla XPCOM！

VisualC++ express下的相同代碼將被編譯。

這很奇怪，我不知道他們爲什麼選擇這個編譯器。不要像我一樣，不要嘗試GCC來編譯Mozilla XPCOM！

你用什麼版本的Gecko SDK來構建？我正在嘗試使用MSVS 2013中的'xulrunner-34.0.5.en-US.win32.sdk'（沒有makefile），它不會構建，無論如何。 – user2173353 2014-12-04 16:42:19

重要的錯誤似乎是這一個，其餘的看起來像後續的錯誤：

nsSample.h：44：23：nsISample.h：沒有這樣的文件或目錄

該文件需要在編譯時被創建從nsISample.idl使用xpidl command line tool：

XPIDL -m頭nsISample.idl

顯然，在新的XULRunner SDK版本你可以使用pyxpidl代替：

header.py -o nsISample.h nsISample.idl

確保您使用-I開關從sdk設置idl-dir，例如：header.py -Ic：\ workspace \ xulrunner-sdk \ idl -o「nsISample.h」nsISample.idl' – weberph 2012-01-17 12:56:46
