Compiler error C3646 _noexcept with Visual Studio 2019

[Juergen Stiebert]

Hello * ,

We are using otlv4.h version 4.0.360 for many years in C++ applications on Windows 10 and AIX with Visual Studio 2015.
Moving forward now to Vs 2019 I get a compilation warning:
warning STL4006: std::uncaught_exception() is deprecated in C++17

and a compilation error:
error C3646: "_NOEXCEPT": Unbekannter šberschreibungsspezifizierer

from the header. Is anybody facing the same issues and is there a workaround/solution available ?
I did myself some investigation and found the following section in otlv4.h:

"#define OTL_ANSI_CPP_11_NOEXCEPT _NOEXCEPT" (line 108 in this version of the header).

Thanks for any information
Juergen

Juergen,

Did you try the latest OTL 4.0.469? OTL 4.0.360 is out of date.

Hello Sergei, yes, I did. The compilation with the newest otlv4.h works fine in VS2019 without this issue. The problem here is, that the new version differs completely from my old one, so I would have to run excessive testing of all applications using it (we have >10.000 users/day) to avoid any regression. This is possible, but not planned or budgeted currently.
Doing test I have seen, that the error can be workarounded simply replacing the line:
define OTL_ANSI_CPP_11_NOEXCEPT NOEXCEPT
with
define OTLANSICPP11NOEXCEPT throw()

Any comment on this ?

Best regards
Juergen

Juergen,

If it works for you, why not? No actual DB APIs calls are different. I'd run some tests, because my philosophy is that when you change even a comma in the code, you need to re-run your test suites.
