Hi Hans and Jens,<div><br></div><div>I just tried compiling the matlab interface again. I was able to do it following *some* of my instructions on the Ipopt website.

</div>I just checked the mingw home page. I found that the documentation was<br>
updated since I had read it last time. However, go to<br>
<a href="http://www.mingw.org/wiki/InstallationHOWTOforMinGW" target="_blank">http://www.mingw.org/wiki/InstallationHOWTOforMinGW</a><br>
and scroll down to 'Manual Installations'. Follow all the instructions<br>
- this will need some time. I checked a few links, for me it looks<br>
like they point all to the gcc4.5 version. So here you will get all<br>
the necessary packages.<br>
<br>
Then, after you updated to the newest version of gcc, try to use it.<br>
In my gcc-version (4.5.0-1) the compiler did not yet work fully<br>
correctly, that is why one had to set the linker-option ( I found this<br>
in the release notes). [I just see that this version is the same as<br>
the version suggested on the mingw page.]<br>

</div>Well, this depends on your environment. I work in the 'msys'-shell as<br>
suggested on the mingw home page. If gcc is called,<br>
(a) either directly by typing on the msys command-prompt,<br>
(b) or by a make-tool<br>
(c) or by some other program<br>
there is always a way to set the compiler options. In my case (b) I<br>
just put it as an option behind the gcc-comand in the makefile.<br>
<div class="im"><br>
> Can you tell me why you chose these<br>

</div>See above: I found it in the release notes.<br>
The (nearly) complete list of all options may be found in the gcc manual.<br>
<a href="http://gcc.gnu.org/onlinedocs/" target="_blank">http://gcc.gnu.org/onlinedocs/</a><br>
But the list is too long for just reading it, you need to use the list<br>
as reference for looking up unknown things.<br>
<br>
<br>
Good luck<br>
