Hello, I'm having an error compiling a C script. I'm using GCC to compile.
It's a DNS scanner, but the problem persists with all my scanning scripts. DNS scanner source code: http://pastebin.com/Ay8cQYUS

dns.c:12:21: error: stropts.h: No such file or directory
dns.c: In function ‘flood’:
dns.c:103: warning: cast from pointer to integer of different size
dns.c: In function ‘main’:
dns.c:239: warning: passing argument 3 of ‘pthread_create’ from incompatible pointer type
/usr/include/pthread.h:225: note: expected ‘void (*)(void )’ but argument is of type ‘void (*)()’
dns.c:254: warning: cast to pointer from integer of different size

Anyone know how to fix this?

Thanks.

Anyone know how to fix this?

Yeah its line 300 in stropts.h.

How do you except us to help with no source code?

That's the source code.

Do you have to link a shared object for stropts?

Say again? I didn't understand what you meant.

add "-pthread" at the end of the gcc command.

Example:
gcc script.c -o script -pthread

[g4143]

add "-pthread" at the end of the gcc command.

Example:
gcc script.c -o script -pthread

The pthread problem wasn't a missing shared object. It was an incorrect function signature.

dns.c:239: warning: passing argument 3 of ‘pthread_create’ from incompatible pointer type
/usr/include/pthread.h:225: note: expected ‘void (*)(void )’ but argument is of type ‘void (*)()’

Could you perhaps give me a fix?

[g4143]

Well the pthread warning is the function signature here.

Code

void recievethread(){
.....
}

it should be.

Code

void recievethread(void){
.....
}

Code

void recievethread(){
.....

it should be.

Code

void recievethread(void){
.....
}

Thank you. I will test the fix ASAP.

Also for the record, there's no way you wrote this but don't know that the problem is you're missing a header. You should probably stop stealing other people's code and learn how to write your own. That's one way to fix your problems.

Actually to OP did post the code with the header file but that doesn't mean its a correct header file or that the header file is present on their machine.

That's what I'm saying. He wrote all that code, but he couldn't understand "dns.c:12:21: error: stropts.h: No such file or directory". The code references a header file that's not there and he can't comprehend that.

Well the problem could be a number of things and all of them are compiler/linker problems which can be nasty if you neglected that part of your C/C++ training.

True, true. I'm just not open to trusting new HF users that just show up with code that "doesn't work for some reason"
