iconv and cygwin

[bnoordhuis]

This is second-hand information but on cygwin you probably need to compile with -Wl,--out-implib,iconv.dll.a and you might have to drop -fPIC.

Let me know if it works and we'll figure out a way to add it to the build script.

Sorry, it doesn't work.
I droped -fPIC. and used:
$ g++ -I/usr/local/include/node -O2 -Wl,--out-implib,iconv.dll.a -shared -Wall
-ansi -o iconv.node iconv.cc

Same effect!
I'm using Windows 7 Professional, 32 Bit Platform

Have you tried it with and without -fPIC?

Another thing you can try is to compile to iconv.dll instead of iconv.node. I'm fairly sure that the cygwin g++ has some file extension heuristics built in.

[irenbi]

Yes, I removed -fPIC. But this was already ignored by g++. I did'nt see that now a library
iconv.dll.a was created.

Creating library file: iconv.dll.a

How to create iconv.dll? Changing only the attribute -o doesn't work!

[bnoordhuis]

According to the documentation, it should be as simple as -o mylib.dll.

Note the 'Linking Against DLLs' sections: it's conceivable that you need to generate a .def from the node executable since that is the place where all the V8 symbols live.

Unless the node.js build script produces a v8.dll nowadays - but that's not the case, is it?

[irenbi]

OK, I got it running.
I don't know if it is the right way, but it's linked. When building node, there is also build a dll node.dll.a. If not you can do it with
$ make dynamiclib
$NODE_PATH/build/default/libnode.dll.a

Also libiconv.a must be linked.
The easyest way ist to copy or make an symbolic link of this libraries to iconv directory.

$ g++ -I/usr/local/include/node -O2 -shared -Wall-ansi -o iconv.node iconv.cc -L/usr/local/lib/node/iconv libnode.dll.a libiconv.a

Now it's OK. It seems that my library pathes are not OK.

Thank's for your help!
