For testing and fun purposes I downloaded the Shakespeare Programming language.
http://shakespearelang.sourceforge.net/
I tried to run the Makefile through make
and it spits out this result:

Does anyone know what could be going wrong when trying to make?
I tried looking at this to resolve my issue but found nothing.

I am trying to cross compile ALSA Lib application for linux-arm based processor. I am using eclipse to do the build for me. The build phase of the application is successful but I get errrors when the gcc linker tries to complete.
I get the following errors

I am using the Sample Playback Program from ASLA-LIB api.
I am wondering what is causing the linker to fail?
You're missing an asound library linkage, add -lasound to your linking flags (see this question which tells where to do that properly in Eclipse). And probably remove -L/proc/asound, I don't think you have your libraries there.
So I've been searching for nigh on two hours now, haven't found a single working solution. I'm using SDL 2.0.4, and all the libraries are for the x64 architecture. I don't get the errors with SDL v1, but I need some of the newer functions. Here's what's coming up:

Your Makefile produces this command:
gcc -lcap -lecryptfs build/obj/main.o ...
which is incorrect. It should be:
gcc build/obj/main.o ... -lcap -lecryptfs
The order of object files and libraries on the link line matters. You can read here or here to understand why it does.
I want to compile the client for redis in C. I've downloaded and installed the libevent library and the hiredis files. I've used this command:
gcc -I/home/tasos/Dropbox/lists/hiredis example-libevent.c -levent
but I get these errors:

why isn't this working?
Use -levent and -lhiredis compile option in command.
I am trying to compile my code for GnuTLS, but on compiling it gives the following errors.
I have checked gnutls.h is present on my system in /usr/include/gnutls/.
What else can be the cause?

This is a linking error. You need to include some library with the -l flag. Taking a wild guess without knowing your setup, I would try -lgnutls
