I'm trying to play a simple file in my c code and so I looked up how to do it on Stack Overflow, but when I tried to apply the answer, which was to download FMOD and use it, I got an error.
The code was:
#include <stdlib.h>
#include <math.h>
#include <stdio.h>
#include <conio.h>
#include <inc/fmod.h>
FSOUND_SAMPLE* handle;
int main()
{
// init FMOD sound system
FSOUND_Init (44100, 32, 0);
// load and play mp3
handle=FSOUND_Sample_Load (0,"mp3.file",0, 0, 0);
FSOUND_PlaySound (0,handle);
// wait until the users hits a key to end the app
while (!_kbhit())
{
}
// clean up
FSOUND_Sample_Free (handle);
FSOUND_Close();
}
but the error told me that:
"gcc -Wall -c "Cases.c" (in directory: C:\Users\xeobi\Documents\C Files)
Cases.c:5:10: fatal error: inc/fmod.h: No such file or directory
5 | #include <inc/fmod.h>
| ^~~~~~~~~~~~
compilation terminated.
Compilation failed."
I am making a game and I have to add some sounds effects and Music.
I Googled it and I found The flowing Code:
#include <conio.h>
#include "inc/fmod.h"
FSOUND_SAMPLE* handle;
int main ()
{
// init FMOD sound system
FSOUND_Init (44100, 32, 0);
// load and play mp3
handle=FSOUND_Sample_Load (0,"my.mp3",0, 0, 0);
FSOUND_PlaySound (0,handle);
// wait until the users hits a key to end the app
while (!_kbhit())
{
}
// clean up
FSOUND_Sample_Free (handle);
FSOUND_Close();
}
But when I compile it I got the flowing error:
➜ Desktop gcc main.c
main.c:1:10: fatal error: 'conio.h' file not found
#include <conio.h>
^~~~~~~~~
1 error generated.
Well, firstly <conio.h> is a C++ library and you're programming in C. It's different!
Then, I remember a C code I wrote years ago, main.c has got the following code (comments are in italian because I am italian):
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include "header.h"
int main(){
register unsigned char x='2';
printf("digitare tasti:\n");
while(1){
while(1){
if(x=='2'){/*blocco2*/ while(x!='1' && x!='3'){x=getch(); scala2(x);}}
if(x=='1'){/*blocco1*/ while(x!='2' && x!='3'){x=getch(); scala1(x);}}
if(x=='3'){/*blocco3*/ while(x!='1' && x!='2'){x=getch(); scala3(x);}}
}
}
system("PAUSE");
return 0;
}
Then, this is the other source file, called file.c:
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include "header.h"
void scala1(unsigned char x){
if(x=='a')beep(131,50);
if(x=='s')beep(147,50);
if(x=='d')beep(165,50);
if(x=='f')beep(175,50);
if(x=='g')beep(196,50);
if(x=='h')beep(220,50);
if(x=='j')beep(247,50);
if(x=='k')beep(262,50);
if(x=='l')beep(294,50);
if(x=='w')beep(139,50);
if(x=='e')beep(156,50);
if(x=='r')beep(185,50);
if(x=='t')beep(208,50);
if(x=='y')beep(233,50);
}
void scala2(unsigned char x){
if(x=='a')beep(262,50);
if(x=='s')beep(294,50);
if(x=='d')beep(330,50);
if(x=='f')beep(349,50);
if(x=='g')beep(392,50);
if(x=='h')beep(440,50);
if(x=='j')beep(494,50);
if(x=='k')beep(523,50);
if(x=='l')beep(587,50);
if(x=='w')beep(277,50);
if(x=='e')beep(311,50);
if(x=='r')beep(370,50);
if(x=='t')beep(415,50);
if(x=='y')beep(466,50);
}
void scala3(unsigned char x){
if(x=='a')beep(523,50);
if(x=='s')beep(587,50);
if(x=='d')beep(659,50);
if(x=='f')beep(698,50);
if(x=='g')beep(784,50);
if(x=='h')beep(880,50);
if(x=='j')beep(988,50);
if(x=='k')beep(1046,50);
if(x=='l')beep(1175,50);
if(x=='w')beep(554,50);
if(x=='e')beep(622,50);
if(x=='r')beep(740,50);
if(x=='t')beep(831,50);
if(x=='y')beep(932,50);
}
The last one, the file header.h. It's code is the following one:
void scala1(unsigned char x);
void scala2(unsigned char x);
void scala3(unsigned char x);
All the source files must be in the same directory. You compile main.c and then, you just need to press a,s,d,..y and 1,2,3. Try! It works, of course if you want to change part of the code, you can do. I hope you enjoy my program, it's funny :)
When I try include gst.h YCM start innoring all error
For example:
#include <math.h>
//#include <gst/gst.h>
main (){ //ycm show error here
int a=0;
int b //and here
}
but
#include <math.h>
#include <gst/gst.h>
main (){ //ycm don't show error here
int a=0;
int b //and here
}
path to gst.h included to .ycm_extra_conf.py . What i miss?
:YcmDiags show all warning and error YCM messages.
You must include all nested headers and then YCM parse your code right.
Also you must install clang lib correct for C/C++ language.
Hello I'm attempting to encode videos using the C ffmpeg libraries. For some reason, when I attempt to create a format context I get an error with:
[NULL # 0x7ff574006600] Requested output format 'mp4' is not a suitable output format
I know that my ffmpeg is compiled with the x264 flags, as a simple
ffmpeg -i test.mov test.mp4
works fine. I'm also linking with all of the generated pch files and everything else from the libav* libraries is working fine. Here's a full working example with the error's I'm recieving:
#include <libavformat/avformat.h>
#include <libavcodec/avcodec.h>
#include <libavutil/avutil.h>
#include <libswscale/swscale.h>
#include <libavutil/opt.h>
#include <libswscale/swscale.h>
#include <libavutil/imgutils.h>
#include <stdio.h>
int main() {
AVFormatContext * output = NULL;
// now lets initialize the actual format element
if (avformat_alloc_output_context2(&output, NULL, "mp4", "test.mp4") < 0) {
printf("%s", "INVALID");
}
return 0;
}
You have to call
av_register_all();
prior to allocating the output context.
why do i get error: 'strcmp': identifier not found in visual studio 2010 C++ Express
#include <string.h>
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
printf("%d",(int)strcmp( "str1", "str2" ));
return 0;
}
Thanks
:( #include <string.h> :(
#include "stdafx.h"
Fun quirk of the MSVC compiler, it generates the exact same error when you compile it like that. Yes, not a lot of 'fun'. It skips everything to find the stdafx.h precompiled header include directive. The string.h doesn't actually get included. Fix:
#include "stdafx.h"
#include <string.h>
Always put the stdafx.h include first.
