I have been using Origin to fit the data. I have a fitting function which is working well in Origin 7.5. But, After upgrading, I just added the fitting function file (used in Origin 7.5) to Origin 8. But, it doesn't work. There are some error codes if I compile the fitting function file in Origin 8. Error codes are as follows; ================================================================ Linking... Done! compiling... _nlfFR_3con_2d.fit C:\Program Files\OriginLab\Origin8\OriginC\system\ORgObj.h(1822) :Error, Function argument lpcstr is not used inside the function body C:\Program Files\OriginLab\Origin8\OriginC\system\ORgObj.h(1822) :Error, error(s) found in compiling function Write Compile Failed! ================================================================ I didn't modify the file of "C:\Program Files\OriginLab\Origin8\OriginC\system\ORgObj.h". If I double-clicked the error message, the code builder shows a not-familiar code which includes "lpcstr". I don't know what to do becuase I don't understand the code. I don't know what the problem is. What shall I do? My fitting function includes a summation. My code is ================================================================= void _nlsfFR_3con_2d( // Fit Parameter(s): double nser, double P1, double P2, // Independent Variable(s): double x, // Dependent Variable(s): double& y) { // Beginning of editable part double dSum = 0; int ser=nser; for(int n = 0; n < ser; n++) { dSum += F(n,P1,P2,x); } y = A*dSum; // End of editable part } =================================================================== Please let me know how I can solve this problem. Thanks, KB. Edited by - cellbiophysics on 02/27/2008 03:44:42 AM [/quote]   Check here to include your profile signature. Check here to subscribe to this topic.
