Problems building the helloworld example

[reedb]

I built using scons and VC++6.0. After some minor changes I was able
to produce an executable: helloworld.dll

The executable seems to be about the correct size but it's missing
some exports which may be needed for the plugin to be detected by
FireFox (it sounds like other posters may have had a similar
problem):

File Type: DLL

Summary

1000 .rdata
1000 .reloc

File Type: DLL

Section contains the following exports for NPDEPLOYTK.dll

Which version of the MS IDE should I be using? Should I build using
the MS IDE or scons?

Thanks,

Try using the solution. You'll probably need a more recent version of MSVC.

The scons file is broken on windows because it doesn't build the resource. I've been meaning to fix that.

I don't see a helloworld.sln file.

That's a fair point ;). I eyeballed the code and I can't see how it exports NP_GetEntryPoints, NP_Initialize and NP_Shutdown, which is necessary on Windows. Feel free to file a bug on the issues page.

The right way to fix it:

I think it needs to incorporate a .def file with these exports, like the one in complex/complex.def. Then the linker needs a /DEF:helloworld.def added to the command line. I've never attempted that in scons.

The easy way to fix it:

Add __declspec(dllexport) to these three functions in nixysa/static_glue/npapi/main.cc. See http://msdn.microsoft.com/en-us/library/a90k134d.aspx.

Thanks

Sorry about that, the complex sample has one.

Those samples need fixin'
