How to determine ElektronSDK version at compile time?
I was looking at example ETA code included in the ElektronSDK version 1.1.0. I found some logic there that I thought might be applicable to by client and added a few lines based on what I saw there. However compilation failed when I tried to compile the client code.
The client is using the ElektronSDK version 1.0.6. It looks like there are additional #defines and fields in structures in the newer version.
Without going into the details regarding why I can't simply start using 1.1.0, I was hoping there was a way to modify the client code to do something like:
#if RSSL_API_VERSION >= 110 // use portions of SDK available starting with version 1.1.0 #endif
But I haven't been able to find #define like that in any of the include files.
Is there such a #define?
If not, can one be added in future versions for such a purpose?
I found a header file that defines the version in the EMA package. It is \Ema\Src\Access\EmaVersion.h.
#ifndef _EMA_VERSION_H_ #define _EMA_VERSION_H_ /*-------------------------------------------------------------------------- CHANGE BELOW HERE --------------------------------------------------------------------------*/ #define Ema_Release_Major 3 #define Ema_Release_Minor 0 #define Ema_Product_Major 6 #define Ema_Product_Minor 1 #define PRODNAME "Elektron Message API EMA " #define PRODVERNAME "3.0.6" #define COMPANYNAME "Thomson Reuters, Oak Brook, IL" #define COPYRIGHTYEAR "2016" #define DDATE "Mon Dec 5 11:00:00 CDT 2016" #define INTERNALVERSION "(Internal Node: Ema 3.0.6.1)"
However, I am unable to find the same in the ETA package. I will contact the development team to verify it.
I searched through all the headers from several versions of the ElektronSDK for anything resembling this for ETA prior to posting this question.
Perhaps there is something we've both missed.
If not, hopefully they'll add it in future versions, it would be useful in certain cicumstances.
I found the new version of Elektron SDK contains the rsslVersion.h in the Cpp-C\Eta\Include directory.
It contains the following information.
#define RSSL_Release_Major 3 // Release major version number
#define RSSL_Release_Minor 3 // Release minor version number
#define RSSL_Product_Major 1 // Release patch number
