I must be doing something wrong but my tries at using past examples of C++ inline code is not working...
is the way I am doing it?
Getting errors like so...
"C:/../..Printtest/stdio.h:39:24: no include path in which to search for stdio.h
C:\Users\..\..\Local\Temp\glbasic\gpc_temp0.cpp:101: error: expected constructor, destructor, or type conversion before ';' "
GOSUB main
SUB main:
INLINE
}
#include <stdio.h>
namespace __GLBASIC__{
ENDINLINE
printf1()
PRINT "HELLO",100,100
SHOWSCREEN
KEYWAIT
ENDSUB
FUNCTION printf1:
INLINE
char z[100] = "I am learning C programming language.";
printf("%s", z);
RETURN 0;
ENDINLINE
ENDFUNCTION
hm.. shoudn't it be something like this:
INLINE
}
extern "C" {
#include <cstdio>
}
namespace __GLBASIC__ {
ENDINLINE
Tried that too just getting./..
gpc_temp0.cpp:53:17: stdio: No such file or directory
Another thing that INLINE shouldn't be in main source file (not sure about this), so this will work:
main source:
GOSUB main
SUB main:
printf1()
PRINT "HELLO",100,100
SHOWSCREEN
KEYWAIT
ENDSUB
second file:
INLINE
}
extern "C" {
#include <cstdio>
}
namespace __GLBASIC__ {
ENDINLINE
FUNCTION printf1:
INLINE
char z[100] = "I am learning C programming language.";
printf("%s", z);
return 0;
ENDINLINE
ENDFUNCTION
Take a note that printf writes to standard output stream, so either app should be compiled as console application, use other function as GLBasic debug doesn't catch stdout info (not sure) or write output to file for example with such batch command in Windows (write file as *.bat):
inline_test.exe >>stdout.txt
Okay, tried that too and got these errors...
C:\Users\Lenovo\AppData\Local\Temp\glbasic\gpc_temp1.cpp:16:18: cstdio: No such file or directory
C:\Users\Lenovo\AppData\Local\Temp\glbasic\gpc_temp1.cpp: In function `DGInt __GLBASIC__::printf1()':
C:\Users\Lenovo\AppData\Local\Temp\glbasic\gpc_temp1.cpp:46: error: `printf' was not declared in this scope
Same result with <stdio> instead of <cstdio>
hm.. strange, before posting I checked that code with GLB 15 & 16.. low chance, but maybe that lib is missing, check in: 'GLBasic\Compiler\platform\Win32\Include'.
Or maybe I did forgot about something trivial ;/
Problem appears with all projects using INLINE? (some complete projects from forum too)
Okay - getting further now..
There was no stdio.h in my include dir so I put one in there (4k in size - so not sure if it was the correct one)
also I changed
#include <stdio.h>
to
#include "stdio.h"
Now it compiles but does not understand printf() function.
UPDATE: Sorted this out > Issue was I had no headerfiles - copied them in and worked first time. Thnks!
What GLB version You are using? On v16 include files are in different path that in v15 (that I posted previously). Maybe some system environment variable was wrongly set, did You tried different GLB versions or reinstalling GLB?
in GLB v15:
cstdio -> 4.26KB
stdio.h ->14.7KB
Do you guys use the headerfiles-pack?
btw. are the headers up to date? do they still fit the current version of the glb version? gcc / g++ (5.30) are from 2015 and the header from 2010.
Should we copy the headers to win32 and win64 folder?Because in the header package is only the win32 folder.Maybe needs that an update.In the next days i would try some INLINE things.
Gernot? :-[
You could put all your header file references within a C header file, then link it at the projects command line in the projects options. The headers will be available to any inline code after that point.
