How do I replace the following in a CLR project, please?
#include <thread>
std::this_thread::sleep_for(std::chrono::milliseconds(60*100));
System::Threading::Thread::Sleep(n);

Trying to define a simple sc_fixed type in Visual Studio 2017:
#include <systemc.h>
#include <sysc/datatypes/fx/sc_fixed.h> # just in case
....
typedef sc_fixed<16, 4> fixed_type;
....
This typedef line resulted an error:
E0864: sc_fixed is not a template
Had no idea why this error popped, even included sysc/datatypes/fx/sc_fixed.h. Why does it say "not a template"?
From INSTALL file shipped with SystemC
SystemC 2.3 includes a fixed-point package that is always built.
When compiling your applications with fixed-point types, you still have
to use compiler flag -DSC_INCLUDE_FX. Note that compile times increase
significantly when using this compiler flag.
Using your code as an example
#include <systemc.h>
#include <sysc/datatypes/fx/sc_fixed.h>
#include <iostream>
typedef sc_dt::sc_fixed<16, 4> fixed_type;
int sc_main(int, char**){
fixed_type ft(1.25);
std::cout << "ft = " << ft << '\n';
return 0;
}
Gives me the output
ft = 1.25
As a caveat it is best to check the docs for your particular version of SystemC as I believe this #define may have been removed in 2.3.3 (I am using 2.3.2) I am not certain.
I got the same type of error message in one of my C++ programs - E0864 - unique_ptr is not a template
I managed to get rid of this error in my program by adding this to my header file.
#include <memory>
My program managed to compile okay using this. I am using Visual Studio 2019 if that helps.
I am trying to write a C function to be executed within PostgreSQL, something that will be declared like
CREATE OR REPLACE FUNCTION ...
RETURNS ... AS 'my_c_function' LANGUAGE C;
I followed the documentation and wrote a code containing stuff like PGFUNCTION_INFO_V1(func); or PG_GETARG_VARCHAR(0);. The problem is Eclipse keeps telling me these cannot be resolved. Here are the libraries I included:
#include <libpq-fe.h>
#include <postgres.h>
#include <fmgr.h>
#include <funcapi.h>
#include <executor/executor.h>
#include <string.h>
Should I include something else ? What am I missing ?
Your index may be out of date. Try rebuilding your index from the project menu.
Project > C/C++ Index > Rebuild
Additionally, make sure your included path is specified in your project settings if there is an issue including <postgres.h>.
I am using Unity 4.3.4f1. and untill right now when i was making Builds for iOS they were working fine.
I just upgraded my Xcode from v5.1 to v6. now the same code is giving me error like the following
/.Project DIR/Classes/Unity/CMVideoSampling.mm:51:122: Use of undeclared identifier 'GL_BGRA_EXT'
can somebody please help me?
thanks
You should try replacing gl.h with glext.h in include statements of the file which contains this error.
Replace the following:-
#include <OpenGLES/ES2/gl.h>
with this :-
#include <OpenGLES/ES2/glext.h>
your include statements should look like this:-
Previously:-
#include "CMVideoSampling.h"
#include "CVTextureCache.h"
#include "GLESHelper.h"
#include <OpenGLES/ES2/gl.h>
#include <AVFoundation/AVFoundation.h>
After replacing:-
#include "CMVideoSampling.h"
#include "CVTextureCache.h"
#include "GLESHelper.h"
#include <OpenGLES/ES2/glext.h>//replace glext.h here
#include <AVFoundation/AVFoundation.h>
It's part of a series of functions that retrieve IP & Mac addresses from the phone.
strcpy(temp, (char *)ether_ntoa((const struct ether_addr *)LLADDR(sdl)));
EDIT: No equivalent function needed, there were just a few missing headers.
EDIT: Added cast to LLADDR(sdl)
As I read it, the error message isn't claiming that the function is missing, only that you don't include its declaration. (I don't know that it exists, only that the message has a different complaint.)
In case it helps, man ether_ntoa tells me:
#include <sys/types.h>
#include <sys/socket.h>
#include <net/ethernet.h>
I included following header file and source code compiled successfully:
#import <arpa/inet.h>
I am trying to compile an 32 bit application. I am aware of problems with it but that is why its being compiled on 64 bit version.
I am hanging at this problem.
Application uses lots of sql stuff.
In sqltypes.h file: (provided by MDAC)
#ifdef _WIN64
typedef INT64 SQLLEN;
typedef UINT64 SQLULEN;
typedef UINT64 SQLSETPOSIROW;
#else
#define SQLLEN SQLINTEGER
#define SQLULEN SQLUINTEGER
#define SQLSETPOSIROW SQLUSMALLINT
#endif
//For Backward compatibility
#ifdef WIN32
typedef SQLULEN SQLROWCOUNT;
typedef SQLULEN SQLROWSETSIZE;
typedef SQLULEN SQLTRANSID;
typedef SQLLEN SQLROWOFFSET;
#endif
For some reason when its compiled on 32 bit platform it works great
But when I try building it on 64 it goes berserk.
Error 61 error C2146: syntax error : missing ';' before identifier 'SQLLEN' ..\external\microsoft sdk\include\sqltypes.h 50
It does not recognize INT64, UINT64.
Is there something I need to enable so it will work under 64 build process?
Missing some #include or #define?
Any help would be great
Thanks
It turned out the problem was that somehow BaseTsd.h was not included (can't believe this is possible)
but as short fix I just included BaseTsd.h manually... i will comment on this answer if i find better solution
Use
#include <windows.h>
It contains BaseTsd.h and other relevant Windows-specific definitions.
