This is more or less a reply to this post:https://www.oxygenbasic.org/forum/index.php?topic=1946.0;topicseen
with added stuff. I don't want to polute that topic.
Mike,
I no longer use LinkRes2Exe as OxygenBasic was the only compiler that I use that needed it. With Charles last update I can retire it. I agree with the icon/version/manifest. I had heard of the version/manifest but not with the icon. I will start adding that also. This is the manifest I use for all coding. Most (if not all) is from José and his FreeBasic AFX Framework.

On the bc9Basic side I am c++ only with VS2019. I do test apps on occasion with the NUWEN distro.
I found my first gotcha with TCLib/msvcrt.dll though which also will affect OxygenBasic unless Charles has found a way to use ucrtbase.dll
I received an email pointing out a problem with the time functions which I verified.
Output using vs2019 on Win 10 and gcc on Linux:
Mon Aug 5 14:52:11 2019
Today is Monday, August 05.
The time is 02:52 PM.
ISO week day is 2019W321.
Output from NUWEN and my bc9/TCLib:
Mon Aug 05 15:18:27 2019
Today is Monday, August 05.
The time is 03:18 PM.
"c" source
#include <time.h>
#include <stdio.h>
#define SIZE 256
int main (void)
{
char buffer[SIZE];
time_t curtime;
struct tm *loctime;
/* Get the current time. */
curtime = time (NULL);
/* Convert it to local time representation. */
loctime = localtime (&curtime);
/* Print out the date and time in the standard format. */
fputs (asctime (loctime), stdout);
/* Print it out in a nice format. */
strftime (buffer, SIZE, "Today is %A, %B %d.\n", loctime);
fputs (buffer, stdout);
strftime (buffer, SIZE, "The time is %I:%M %p.\n", loctime);
fputs (buffer, stdout);
strftime (buffer, SIZE, "ISO week day is %GW%V%u.\n", loctime);
fputs (buffer, stdout);
return 0;
}
Reply from Stephan T. Lavavej (NUWEN)
This is almost certainly caused by MinGW's use of msvcrt.dll in Windows, which is an old version of the CRT. VS 2017+ uses ucrtbase.dll, the modern Universal CRT with C99 support.
I would be interested if anyone knows how to use ucrtbase.dll. I did search a bit but no luck with actual code.

And the OxygenBasic code:
use rtl64
use console
use corewin
typedef unsigned long time_t
typedef unsigned int clock_t
% SIZE = 256
struct tm {
int tm_sec; /* seconds after the minute [0,60] */
int tm_min; /* minutes after the hour [0,59] */
int tm_hour; /* hours since midnight [0,23] */
int tm_mday; /* day of the month [1,31] */
int tm_mon; /* month since January [0,11] */
int tm_year; /* years since 1900 */
int tm_wday; /* days since Sunday [0,6] */
int tm_yday; /* days since January 1 [0,365] */
int tm_isdst; /* Daylight Saving Time flag */
}
Function main() As sys
char buffer[SIZE]
time_t curtime
struct tm* loctime
curtime = time(NULL)
loctime = localtime(@curtime)
buffer = (char*)asctime(loctime)
print buffer
strftime(buffer,SIZE,"Today is %A, %B %d.", loctime)
print buffer cr
strftime (buffer, SIZE, "The time is %I:%M %p.", loctime)
print buffer cr
strftime (buffer, SIZE, "ISO week day is %GW%V%u.", loctime)
print buffer cr
wait
End Function
main()

Hi James,
Re. your manifest file, I'd only suggest changing processorArchitecture="amd64" to processorArchitecture="*", which makes it applicable to both 32 and 64 bits.
Re. MinGW, I'm currently using the MinGW-w64 8.1.0 distro with Posix threads and Windows SEH in the Code::Blocks environment. This distro yields for me significantly smaller (up to 5 times) statically linked executables than its TDM GCC or NUWEN counterparts. It also offers Unix time.
Re. Unix time and VC, I'm using mostly MS VS2013. It's a Pro version that still covers all my needs. Like MinGW-w64 8.1.0, VS2013 also provides much of C99 and C++11 compatibility.
I do not think Charles will be able to develop a direct interface between Oxygen and C++ libraries. Such tasks are usually resolved through a dedicated proxy DLL that would black-box the C++ entity creation and caller engine, on the one side, while exposing only a simpler C-language compatible utility API, on the other side. The latter can then be utilized by other programming languages like OxygenBasic in a usual way.

Just a FYI; the source for ucrt is here on my machine:
C:\Program Files (x86)\Windows Kits\10\Source\10.0.17763.0\ucrt\
