I have been able to remove almost all errors except these 5 errors in this C program (too long to paste so providing link).
http://codepad.org/AfqrDojN
The errors I receive are as follows:
I am using the following libraries:
#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <dos.h>
#include <conio.h>
What could be the issue?
you are redefining the function remove that is already declared in
#include <stdio.h>
changing the name of your function to (for example) void myremove() will probably solve your problem.

I have been getting these compiler errors when I am trying to create a self-made containers
warning: implicit declaration of function ‘sys_pivot_root’; did you mean ‘SYS_pivot_root’? [-Wimplicit-function-declaration]
TRY (sys_pivot_root(wd, "/dir/oldroot"));
And then I change sys_pivot_root into SYS_pivot_root then the following error message appears.
install_rootg.c:61:9: error: called object is not a function or function pointer
TRY (SYS_pivot_root(wd, "/dir/oldroot"));
and then I look into syscall.h to see if the function exists. I get the following line
asmlinkage long sys_pivot_root (const char __user * new_root, const char __user * put_old)
why am I getting these compiler errors? I haven't been able to resolve this for like a week now.
I include the header files in this exact order.
#define _GNU_SOURCE
#include <errno.h>
#include <stdio.h>
#include <sched.h>
#include <stdlib.h>
#include <sys/wait.h>
#include <sys/mount.h>
#include <sys/stat.h>
#include <limits.h>
#include <sys/syscall.h>
#include <unistd.h>
#include <sys/mman.h>
any help would be appreciated. Thank you in advance!
I figured out, so there isn't such function already defined as pivot_root.
you can just call syscall(SYS_pivot_root, ...
and pivot_root is called.
look at the man page for the usage.
I am unable to compile my code successfully due to undefined references.
I am using the STM32Cube IDE compiler which is based of atollic true studio.
The undefined references are due to headers not linking.
I have included the headers into my main program and have included them in the include path for the compiler.
#include "base64_codec_transport.h"
#include "line_buffer_transport.h"
#include "modem_ussd_transport.h"
#include "thingstream_transport.h"
#include "client_api.h"
#include "client_platform.h"
#include "client_set_callback.h"
#include "custom_modem_transport.h"
#include "debug_printf_core.h"
#include "log_client_transport.h"
#include "log_modem_transport.h"
#include "log_protocol_transport.h"
#include "log_transport.h"
#include "modem2_transport.h"
#include "modem_set_callback.h"
#include "modem_transport.h"
#include "predefined_topics.h"
#include "quectel_modem2_config.h"
#include "ring_buffer_transport.h"
#include "sdk_data.h"
#include "serial_transport.h"
#include "sim7600_modem2_config.h"
#include "transport_api.h"
#include "ublox_modem2_config.h"
The consol errors are below:
All these functions are defined in their respective headers as follows, to give one example.
#define line_buffer_transport_create Thingstream_createLineBufferTransport
which then points to
extern ThingstreamTransportResult Thingstream_line_buffer_deliver(ThingstreamTransport *self);
I have also rebuilt the index multiple times and still no success.
I don't know what else to do to solve this.
I am trying to recompile app_fax.c to app_fax.so (module used by asterisk to send/receive fax under 4PSA system) which needs a header file called 4psa_base.h
The reason I am recompiling this c program is because of a timeout setting inside the program that kills fax calls that last more than 30 minute. what I did was just change that value
I have looked everywhere for this file with no luck. its not anywhere that I can find it.
Is there anyone that may have any clue where to find this file?
Thanks,
Javid
I'm not sure which version of Asterisk you are using, but app_fax (which is not the preferred fax module in Asterisk) depends on spandsp. Looking at the source, it does not include the header file you're referring to:
ASTERISK_FILE_VERSION(__FILE__, "$Revision$")
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <inttypes.h>
#include <pthread.h>
#include <errno.h>
#include <tiffio.h>
#define SPANDSP_EXPOSE_INTERNAL_STRUCTURES
#include <spandsp.h>
#include <spandsp/version.h>
#include "asterisk/lock.h"
#include "asterisk/file.h"
#include "asterisk/logger.h"
#include "asterisk/channel.h"
#include "asterisk/pbx.h"
#include "asterisk/app.h"
#include "asterisk/dsp.h"
#include "asterisk/module.h"
#include "asterisk/stasis.h"
#include "asterisk/stasis_channels.h"
#include "asterisk/format_cache.h"
Is this a custom patch to Asterisk?
Looking at line 21 in radio.c
Where is "radiotimer_capture_cbt" structure defined? I am unable to locate it.
I am hoping the C/C++ experts from the community could help me locate the definition of this structure.
Here : https://github.com/openwsn-berkeley/openwsn-fw/blob/a1dbfd8a3341ac3a82ffbb610b4d749f44c429d9/firmware/openos/bsp/boards/radiotimer.h
typedef void (*radiotimer_compare_cbt)();
Just follow the header files
Almost certainly in one of the header files:
#include "board.h"
#include "radio.h"
#include "at86rf231.h"
#include "spi.h"
#include "radiotimer.h"
#include "debugpins.h"
#include "leds.h"
I have this message error: storage size of 'start' isn't known when I compile my program. The error is here:
struct _timeb start, finish;
I make a header file when I've put declarations and prototypes
#include <stdio.h>
#include <stdlib.h>
#include <sys/timeb.h>
#include <time.h>
In my .c file, I put
#include "image.h"
#include <math.h>
This usually indicates that the description of the mentioned struct has not yet been encountered, and so you are trying to create a variable of a type the compiler doesn't yet know about. Likely you are missing a header:
#include <sys/timeb.h>
