I used the thrift compiler to generate C-glib files. However they never seem to compile.
My .c file:
#include "zipkin_core_types.h"
void genLogfile(Span span, char *filename) {
}
My .h file
#include "zipkin_core_types.h"
#ifndef SPANLOGGERCH
#define SPANLOGGERCH
void genLogfile(Span span, char *filename);
#endif
command line options:
gcc -g -o main -I/usr/include/glib-2.0/ -I /usr/lib/glib/include/ -I/usr/local/include/thrift/ -I/usr/local/include/thrift/c_glib -I. -L/usr/local/lib/-I/usr/lib/glib-2.0/include/ -lthrift main.c zipkin_core_types.c SpanLoggerC.c
I get 5 screens of error messages. Here's the top few lines, they mostly look like this. Any suggestions woule be appreciated:

I've some error on this class construction,
cwrapper.h
#include "SimpleCLM.h"
using namespace std;
using namespace cv;
class A{
public:
A();
~A();
met1();
};
void *A_init();
A_m1(void *p);
cwrapper.c
#include "cwrapper.h"
using namespace std;
using namespace cv;
void *A_init()
{
A *p = new A;
return (void *)p;
}
A_m1(void *p)
{
return p->met1();
}
A::met1()
{
return begin();
}
begin is a function in SimpleCLM.h.
Here is the errors on make,

It is impossible to create a class in C; you would have to tell the compiler somehow that you want to compile C++.
This is the full error message
hw2.c:13: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘attribute’ before ‘<’ token
This is the line in question
int main <void>
I can post more info if anyone needs it.
I assume you're trying to create a main method?
int main(void){
// lol code
}

Here is the header file where the error is coming from(The line numbers don't match up because I stripped all the comments out of the file to shorten it):
/* gpio_api.h - General Purpose Input/Output API

#ifndef MSP_GPIO_API_H

It seems simple enough, yet I can't figure out what my problem is.
You have to include <stdbool.h> in your program. bool is actually a macro defined in stdbool.h header file.
I'm trying to compile a matlab wrapper for libdc1394 which is a library for firewire cameras.
I get a strange error involving some inline functions in a header file.
I'm working on ubuntu 12.04 with gcc-4.6. I've compiled other mex files with success. This wrapper was also difficult to compile in mac.

Any ideas?
Well Simons proposal was correct. Only catch I didn't know was that you can't give cflags directly to mex. You have to alter your mexopts.sh file.
Also I had to remove -ansi flag because it contradicts with c99.
How to specify C99 via CFLAGS modification on the command line:
mex -v -largeArrayDims CFLAGS="\$CFLAGS -std=C99" dc1394mex.c
I'm trying to make a global variable, initialized in my msh.c file as:
volatile sig_atomic_t sig_int = 0;
This alone seems to be fine. However if I go to my proto.h file(which is included in all the c files for this project), and type:
extern volatile sig_atomic_t sig_int;
It throws a bunch of errors:
gcc -c -Wall msh.c arg_parse.c builtin.c expand.c
In file included from arg_parse.c:5:
proto.h:3: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘sig_int’

In file included from expand.c:11:
proto.h:3: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘sig_int’
make: *** [msh.o] Error 1
How exactly do I make this variable global? Thanks.
Your proto.h file needs to include <signal.h> so that the sig_atomic_t type is defined, that's all.
