I'm trying to work with the Trading System Based On Alert Condition source code provided with SC. On attempting to compile it however (after I give it a DLL name), I get the following error: In file included from scstructures.h:109,
from sierrachart.h:22, from TradingSystemBasedOnAlertCondition.cpp:1: In constructor 'SCString::SCString(const char*)', inlined from 'void scsf_TradingSystemBasedOnAlertCondition(SCStudyInterfaceRef)' at TradingSystemBasedOnAlertCondition.cpp:272:54: SCString.h:174:11: warning: 'char* strncpy(char*, const char*, size_t)' specified bound depends on the length of the source argument [-Wstringop-overflow=] 174 | strncpy(m_String, SourceString, StringLength); | ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ SCString.h: In function 'void scsf_TradingSystemBasedOnAlertCondition(SCStudyInterfaceRef)': SCString.h:735:36: note: length computed here 735 | const size_t StringLength = strlen(String); | ~~~~~~^~~~~~~~ -- End of Build -- 18:50:39 This appears to be an internal issue I can't do anything about. Is there some fix for this? I'm running build 2568. |

Change this: const size_t StringLength = strlen(String);
to: const size_t StringLength = String.GetLength();

Thanks, but that line does not exist within the .cpp provided.

Note that the error message is not to do with the code I'm compiling, it's referring to something within SC.

Disregard the warning. It is incorrect. It is not going to cause any problem.

But the study won't compile. How do I disregard the warning and make it compile anyway?
