Error: Cannot load Firebird client library: 'fbclient.dll'.

With node-firebird-driver-native installed, i tried to run the test but this happened:

Yes, it is a Firebird4 fbclient.dll, thanks for the attention.

It must be on the PATH (or in the same directory of the .exe file).

Or, use the absolute path instead of getDefaultLibraryFilename().

Using FS to read the file with "getDefaultLibraryFilename()" works correctly, already tried with absolute path too, but it still doesn't work.

I do not understand what you mean. What worked and what not worked?

I tried "fs.statSync()" with "getDefaultLibraryFilename()" and absolute path, both returned the dll file info, but neither worked with "createNativeClient()".

And what? As I said, to load a DLL with not-absolute path, it must be in same directory of .exe file or its directory must be in PATH environment variable.

But even with absolute path it still doesn't work,

Still trying but the error continues...

As the output shows, the DLL is there, with an "absolute" path, the path is correct, FS reads the DLL file info, but the lib can't load the client. It's not a problem of path.

Are you sure you are using node and Firebird of the same architecture (32 vs 64 bits)?
