From: Mark on 9 Sep 2009 14:05 Oscar, I assume you found the answer to your issue, but just in case anyone would like to know he was missing a linkage to the mclmcrrt.lib file, which should be located in the /extern/lib folder.

From: Oscar on 11 Sep 2009 06:10 Hi Mark, yes, you are right I found out what was wrong. But now, after compiling and linking (which is ok) and, when I'm getting to the first line of code were I initialize the takeUp vector, it returns a non-valid memory address, i.e. 0x00000000. I think that there's something wrong with the line but don't know what. I copy here the line code takeUp=mxCreateDoubleMatrix(1, 1, mxREAL); Thanks "Mark " <desertvet7(a)yahoo.com> wrote in message <h88qp4$g3g$1(a)fred.mathworks.com>... > Oscar, > > I assume you found the answer to your issue, but just in case anyone would like to know he was missing a linkage to the mclmcrrt.lib file, which should be located in the /extern/lib folder. > > "Oscar " <osgarpe(a)hotmail.com> wrote in message <h44taa$9ou$1(a)fred.mathworks.com>... > > I'm facing the same problem.
