I should have use '/MTd' rather than '/MD' for the static debug version of
Ipopt. My main point was to avoid the mixing of release and debug runtimes
as Damien mentions below.</FONT></SPAN></DIV><BR>

<DIV></DIV>Justin,<BR><BR>/MD means link for the C/C++ release, runtime dlls
(msvc... dlls etc). /MDd means link for the C/C++ debug, runtime dll
(msvc...d dlls). /MT means link the C/C++ release, runtime static library
(libc.... libs etc). /MTd means link the C/C++ debug, runtime static
library (libc...d libs). <BR><BR>If the notes say release is /MT and debug
is /MD, that's linking static release libraries on a release build, and dynamic
release dlls on a debug build. That's a bit unusual, and won't always work
well on a debug build, depending on how exceptions or errors are
handled.<BR><BR>It's generally not a good idea to mix debug and release
runtimes, and sometimes you can get weird link errors mixing static lib and dll
runtimes, so use only /MT or only /MD everywhere for release, and only /MTd or
only /MDd everywhere for debug. You can't control what third parties do
with their code though. I generally do /MD or /MDd for the runtimes,
because the dll is only loaded once, no matter how many times it's linked to
from anyone's library.<BR><BR>Damien<BR><BR>On 21/09/2010 9:56 AM, Vallon,
