For linking in the cs50 library (which you should have installed from https://github.com/cs50/libcs50 according to the instructions there), your linking command should specify the -lcs50 argument.

make usually needs a Makefile to control the build. In its absence it can use some implicit rules to guess the build process, like that hello.o could be built from hello.c and hello could be linked from hello.o and so forth, but it certainly cannot guess that libcs50 should be linked in.

Fortunately, the implicit linking rules include the contents of the variable LDLIBS in the correct, so you can fix this by writing a simple Makefile in the same directory, containing just

QUESTION

How to avoid segmentation fault in recursive function with strings in C?

Asked 2018-Jul-15 at 01:23

Note: I am not trying to get the algorithmic implementation! I already have it figured out in Java. I just can't seem to get my logic to work in C. Below is the Java code (which works) followed by the C99 code that breaks.

The high-level coding challenge that is presenting the segfault in my implementation is:

How to find all combinations of k length and smaller using alphabet of length n with repeating elements in C?

Problem

Code compiles, but I get a segmentation fault at runtime.

Notes / Observations

This is from a self-paced edX course I'm working my way through. I've already done the "less comfortable" challenges, and frankly they were a bit too easy. I'm now trying to go above the requirements and do this "more comfortable" (read more challenging) challenge. It is one of the more advanced beginner challenges.
I'm not a beginner programmer, but pretty much a novice with C.
As far as I understand it, the is a custom header file that implements some things that simplify (read abstract away) command-line input and handling of strings. Documentation in it can be found at the cs50.net site and on the cs50lib GitHub page
I can't figure out the correct way to pass the values to the recursive function and need to utilize address referencing/dereferencing. Unfortunately my C is a bit fuzzy compared to other langs.

One of the key differences between your Java code that works and the C code that doesn't is in the printCombinations() function.

QUESTION

What does cc (file name).c -l(library's name) -o (output file name) do and why does it work when make doesnt?

Asked 2017-Oct-10 at 18:12

I started getting into c programming and was following a series of lectures on the cs50 platform, due to some problems with my internet i decided it would make sense to download the library so i could work on the problem sets while offline, after downloading the library and including it in the project the make command wouldn't work at all giving me this output

cc main.c -o main /tmp/ccz5QZev.o: In function main': main.c:(.text+0x18): undefined reference toget_string' collect2: error: ld returned 1 exit status : recipe for target 'main' failed make: *** [main] Error 1

get_string is defined on the #include "libcs50-develop/src/cs50.h", some one told me that running "cc main.c -lcs50 -o main" instead of "make" would solve the issue, the suggestion did work, but i wasn't able to contact the person again to find out why. could someone explain to me what is happening?

Your invokation is performing two steps, the compilation and the linking.

The error you are getting is from the linking step when the linker is attemping to bind the symbols declared in the header cs50.h

There must be a library file that also needs to be included in the compilation.

That seems to be the advice you received and I agree. The problem might be that the linker needs to know where the library "cs50" resides in the path.

That is typically indicated in a further switch to the linker to tell the linker where the libraries are located.

For the gcc compiler one indicates the directories to search for the library using the -L switch. (see options)
