fails to build in Windows

Question

fails to build in Windows

Closed this issue 9 years ago · 7 comments

benoror commented 9 years ago

Hi,

I'm trying to build recent versions of node-libxslt on Windows: I tried different configurations:

Windows 10
node 0.10., 0.12., 4.*.0 (all 32bit using NVM)
MS Visual C++ 2013 Express / MS Visual C++ 2010
Updated node-gyp

I get node_libxslt.obj : error LNK2001: unresolved external symbol errors

Any hint would be appreciated! 😄 Cheers!

Detailed messages:

Have you solved the problem ?

Answer 2 · 2015-11-01T17:23:01.000Z

Nope, switched to Unix env for building it

Answer 3 · 2015-11-01T19:06:42.000Z

Same here. Doesn't build on Windows. Switched to Linux.

These two classes are part of my changes from single-threaded libxmljs to multi-threaded libxmljs-mt. In my opinion, they should be included in the dependency object from the libxmljs-mt directory. Here is the implementation. Can someone with access to a Windows machine and some debugging knowledge check in which object files these symbols end up, and perhaps also why that's not enough to satisfy the linker? Do I have to somehow export the symbols as well?

Do I have to somehow export the symbols as well?

Apparently I do have to write __declspec(dllexport) on all the symbols I whish to export, and probably the same with dllimport in the headers when using the symbols. I did some of this in libxmljs-mt-0.15.1, but I still get errors from AppVeyor:

libxslt.lib(extensions.obj) : error LNK2001: unresolved external symbol _xmlModuleClose [C:\projects\node-libxslt\build\node-libxslt.vcxproj]
libxslt.lib(extensions.obj) : error LNK2001: unresolved external symbol _xmlModuleSymbol [C:\projects\node-libxslt\build\node-libxslt.vcxproj]
libxslt.lib(extensions.obj) : error LNK2001: unresolved external symbol _LIBXSLT_DEFAULT_PLUGINS_PATH [C:\projects\node-libxslt\build\node-libxslt.vcxproj]
libxslt.lib(extensions.obj) : error LNK2001: unresolved external symbol _xmlModuleOpen [C:\projects\node-libxslt\build\node-libxslt.vcxproj]
C:\projects\node-libxslt\build\Release\node-libxslt.node : fatal error LNK1120: 4 unresolved externals [C:\projects\node-libxslt\build\node-libxslt.vcxproj]

So it seems as if now that my memory sentinels get exported correctly, I'll next have to worry to get all the symbols from libxml itself exported correctly. Preferrably without modifying their codebase since it's a git submodule. I must confess that right now I don't see why this doesn't work already, since xmlmodule.c defines IN_LIBXML before including xmlversion.h which in turn includes xmlexports.h defining XMLPUBFUN as an alias to __declspec(dllexport) which in turn decorates xmlModuleClose in xmlmodule.h. Strange. Any ideas?

Apparently a Windows build won't re-export symbols which are marked for DLL export in some static library used by the top level module. @benoror and @tobha, can you give #32 a try please?
