I'm using Mingw's gcc compiler but when I started using the -std options, the linker started complaining about references (except for -std=gnuXX).
I can't find anything about this (maybe I'm really bad at research) because most of the results are on linux and/or relate to other problems with ld..
Here is the command I typed :
gcc src/main.c -o bin/main.exe -std=c11 The same occurs with c89,c99,c17 etc..
Here is my test code :
#include <stdio.h>
#include <stdlib.h>
int main (void)
{
printf("Cool\n");
return EXIT_SUCCESS;
}
Here is the command output

I'm also wondering if I should use Mingw-w64 or Clang/LLVM instead.. ?
EDIT : It works fine with Mingw-w64 so I switched, thanks !

I have a sample code temp.c:
#include "win.h"
win.h is in /home/me/Documents/Code/libs/TUI/win.h and has all the declared functions
which functions are defined in some files in /home/me/Documents/Code/libs/TUI/win/[lots of files].c which every file starts with
#include "../win.h"
//functions
So while using gcc -I /home/me/Documents/Code/libs/TUI /home/me/Documents/Code/temp.c -o /home/me/Documents/Code/temp, gcc returns every function used in temp.c declared in win.h as undefined
Exact output:
gcc -g -I/home/me/Documents/Code/libs/TUI /home/me/Documents/Code/temp.c -o /home/pk/Documents/Code/temp
/usr/bin/ld: /tmp/cc4berEn.o: in function `main':

notes
Using -I /home/me/Documents/Code/libs/TUI/win.h returns fatal error: win.h: No such file or directory 3 | #include "win.h"
/home/me/Documents/Code/libs/TUI is a folder
Writing every source file's name is not an option
Already tried this
-g for debug
I'm trying to work with the CFITSIO library to process FITS images in C. I followed the installation guide from the documentation and I checked that it was successful installed. However when I compile the following code:
#include <string.h>
#include <stdio.h>
#include "fitsio.h"
int main(int argc, char *argv[])
{
fitsfile *fptr;
char card[FLEN_CARD];
int status = 0, nkeys, ii; /* MUST initialize status */
fits_open_file(&fptr, argv[1], READONLY, &status);
fits_get_hdrspace(fptr, &nkeys, NULL, &status);
for (ii = 1; ii <= nkeys; ii++) {
fits_read_record(fptr, ii, card, &status); /* read keyword */
printf("%s\n", card);
}
printf("END\n\n"); /* terminate listing with END */
fits_close_file(fptr, &status);
if (status) /* print any error messages */
fits_report_error(stderr, status);
return(status);
}
I get the following error:

I tried passing the files as an argument on the command terminal and hard forcing a FITS file into the program, but still wasn't able to run the program successfully. I couldn't find a lot of information about this library, so any help would be appreciated.
I am trying to use C, MINGW and GLFW to create a program and I keep on getting this error when compiling.

This is my code
#include "GLFW/glfw3.h"
#include <stdio.h>
#define GLFW_INCLUDE_GLCOREARB
int main() {
GLFWwindow* window;
if (!glfwInit()) return -1;
window = glfwCreateWindow(640, 480, "Test", NULL, NULL);
if (!window)
{
glfwTerminate();
return -1;
}
glfwMakeContextCurrent(window);
while (!glfwWindowShouldClose(window))
{
glClear(GL_COLOR_BUFFER_BIT);
glfwSwapBuffers(window);
glfwPollEvents();
}
glfwTerminate();
return 0;
}
So its basically just the given example on glfw website.
I use this command to build:
gcc -o Test.o Main.c -IGLFW -IGL -dynamic ./libs/glfw3.dll ./libs/glew32.dll -lopengl32 -static ./libs/libglfw3.a ./libs/glew32.lib ./libs/glew32s.lib
I dont have any issues with compiling the glfw but I have problems with GLEW, maybe it is because it is lib files instead of a.
I have a source, that I'd like to build and link against the libav library on Linux.
I followed the compilation guide of ffmpeg here: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
Everything works.
I build the included examples like this: FFmpeg: building example C codes
It also works.
Now, I'd like to build my own little applications, where I try to learn about using libav. My current problem is, that by using the command line
gcc muxing.c -g -I ../../../ffmpeg_build/include/ -L ../../../ffmpeg_build/lib/ -lavdevice -lavformat -lavfilter -lavcodec -lswresample -lswscale -lavutil -lm -lz -lpthread -lfdk-aac -lmp3lame -lx264 -lva -lX11
I get to this point:

So, what can I do, to get it compiled and linked fully?
I have to compile a C program on linux(ubuntu) with gcc. Which is dependent to openssl libraries.
#include <openssl/crypto.h>
#include <openssl/pem.h>
#include <openssl/err.h>
#include <openssl/bio.h>
#include <openssl/x509.h>
#include <openssl/pem.h>
#include <openssl/err.h>
I've downloaded libcrypto and libopenssl package from repository. But still I'm getting this error

Can anyone please tell me what I should do to, get rid of this error.?
Thanks,
You haven't linked the crypto and openssl libraries:
gcc opensslhello.c -lssl -lcrypto
