segmentation fault when using kernel32.dll.so and oleaut32.dll.so

[Anil Akurathi]

Hi,
    I need functions like 'MultiByteToWideChar', 'SysAllocStringLen', etc
which are in kernel32.dll.so and oleaut32.dll.so libraries. I have some of
questions regarding using them.

- How can I link these libraries with my program. Using
option -lkernel32.dll looks for libkernel32.dll.so file.
- I tried renaming the files and also creating soft links using
libkernel32.dll.so to kernel32.dll.so.
- If I link like that, my program is giving a 'segmentation fault' error.
- I tried using libraries produced by compiling on my uptodate RH8.0 machine
and also the libraries from the RH8.0 rpm available on sourceforge.net.
- I implement an XPCOM class using these libraries and when I try to create
an object, it gives the 'Segmentation Fault'.
- I tried using libwine.so but it doesn't contain the above functions I
need.

If anybody knows how to use these libraries, please mail back. Thanks in
advance.

Regards,
Anil

First off, you can't use these functions from outside a WineLib app. I'll
assume you're using winegcc because of that.

You shouldn't need to, apps are automatically linked against kernel32
iirc. Something like this for oleaut32:

winegcc -o fooapp -loleaut32 fooapp.c

You should read the WineLib developer guide - you cannot use Wine code
from a standard Linux app I'm afraid.
