c++ - Build XPCOM Mozilla Sample Component -

i'm trying build xpcom component available here: http://mxr.mozilla.org/mozilla-central/source/xpcom/sample/

i tried compile own makefile, component isolated whole mozilla sources.

so here file tree:

frinux@bureau /cygdrive/c/dev/central_sample $ ls -rlah .: total 57k d---------+ 1 frinux none 0 jan 15 21:28 . d---------+ 1 frinux none 0 jan 15 20:34 .. ----------+ 1 frinux none 989 jan 15 21:22 makefile ----------+ 1 frinux none 2.4k jan 15 21:05 nsisample.idl ----------+ 1 frinux none 6.0k jan 15 21:05 nssample.cpp ----------+ 1 frinux none 5.1k jan 15 21:06 nssample.h ----------+ 1 frinux none 2.0k jan 15 21:06 nssample.js ----------+ 1 frinux none 131 jan 15 21:06 nssample.manifest ----------+ 1 frinux none 4.7k jan 15 21:06 nssamplemodule.cpp d---------+ 1 frinux none 0 jan 15 21:28 programme ----------+ 1 frinux none 8.7k jan 15 21:06 xpconnect-sample.html ./program: total 16k d---------+ 1 frinux none 0 jan 15 21:28 . d---------+ 1 frinux none 0 jan 15 21:28 .. ----------+ 1 frinux none 2.7k jan 15 21:07 makefile.in ----------+ 1 frinux none 4.5k jan 15 21:07 nstestsample.cpp

here makefile made :

cxx = c++ cppflags += -fno-rtti \ -fno-exceptions \ -shared # alter point @ gecko sdk directory. gecko_sdk_path = /cygdrive/c/dev/greenchallenge/xulrunner-sdk-9.0.1 # gcc define allows not have #include mozilla-config # in every .cpp file. if not using gcc remove line , add together # #include "mozilla-config.h" each of .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)

i'm trying build cygwin under windows (with gcc & g++ installed).

when compiling, i'm getting thos errors, , after hours of research, still don't understand them:

it if there errors in mozilla code... doing wrong ?

thanks !

the of import error seems one, rest looks follow-up errors:

nssample.h:44:23: nsisample.h: no such file or directory

that file needs created @ build time nsisample.idl using xpidl command line tool:

xpidl -m header nsisample.idl

apparently, in newer xulrunner sdk versions utilize pyxpidl instead:

header.py -o nsisample.h nsisample.idl
