Link error when compiling XPCOM component using gecko 15

[ah6511]

Hi, I am trying to compile the sample (http://mxr.mozilla.org/mozilla-central/ ... om/sample/) XPCOM component using latest gecko SDK (15) with VS 2010. It has following error with debug build:

The release build is fine. How can I build a debug version of the component?
I have following preprocessors: MOZ_NO_MOZALLOC;XP_WIN;XP_WIN32
and link with following libs: nspr4.lib;xpcom.lib;xpcomglue_s.lib
any help will be greatly appreciated.

I resolved this issue with changing of 'Runtime library' (in Project settings -> C/C++ -> Code Generation) from 'Multi-threaded debug (/MTd)' to 'Multi-threaded (/MT)'
(or from 'Multi-threaded debug DLL (/MDd)' to 'Multi-threaded DLL (/MD)').

@ggurov, Hi, I am getting the following error while compiling the nsSampleModule.cpp. I tried your suggestion, still getting this error. Can you explain me how you got this sample compiled?

Thanks
caf

@caf_anto

You got compiler errors, not linker ones. I don't know what is wrong with your setup, but it is not the linker settings (only). Maybe some #include is missing.
Actually I used my own project, not the mozilla sample.

[ggurov]

With the introduction of the new style - new major release every 2 months - mozilla guys break the compilation compatibility of our components very often. I have to make changes in my .cpp file with almost every new SDK. Some of these changes are just about #include directives (removing or changing/adding some). It can be that the sample project is outdated (or too new) against the sdk version, which you use.
