What and where is the error ? TSerial.cpp is not an opencv file
I had been searching for a solution for hours during the WE... LBerger, thanks, I removed Tserial.cpp. I have now 6 errors: LNK 2019, Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol "public: __cdecl Tserial::Tserial(void)" (??0Tserial@@QEAA@XZ) referenced in function main OpenCV1 C:\Users\user\Documents\Visual Studio 2015\Projects\OpenCV1\OpenCV1\Main.obj 1
Are the commands for serial no updated? what is wrong?
berek, thank you.while searching solutions, I saw something about including windows.h, I tried but it didn´t work...also tried to write the Serial lines at the top, but still no success.
OK.Now it is reduced to 2 errors, thank you! I can´t find a new version of that code... I have a C2664 and a C4496 errors, this last one is about an unsafe function, as you suggested: Severity Code Description Project File Line Suppression State Error C4996 'strncpy': This function or variable may be unsafe. Consider using strncpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details. OpenCV1 c:\users\user\documents\visual studio 2015\projects\opencv1\opencv1\tserial.cpp 91
Severity Code Description Project File Line Suppression State Error C2664 'HANDLE CreateFileW(LPCWSTR,DWORD,DWORD,LPSECURITY_ATTRIBUTES,DWORD,DWORD,HANDLE)': cannot convert argument 1 from 'char [10]' to 'LPCWSTR' OpenCV1 c:\users\user\documents\visual studio 2015\projects\opencv1
I have only one now: the last one about the argument C2664 error
hi again! I founded this! : http://stackoverflow.com/questions/39..., maybe it is OK now...I changed the properties to Character Set: Not Set
^so, can we close it now ? (again, this is all off-topic)
yes sure! should I mark it as "closed"? how it works in the forum?
