/usr/bin/lib cannot find library


I am new to linux, and am trying to get some programs up and running to read .fits files. I'm sure I'm making some rookie mistake, but have been having trouble with the following error message when trying to compile the simple listhead.c demonstration file (not written by me, so it should be free of issues!):

/usr/bin/ld: cannot find -lcfitsio.a
collect2: ld returned 1 exit status

Here is my compile command:

gcc listhead.c -o listhead -I/home/username/Desktop/scftisio/@CFITSIO_PREFIX@/include -L/home/username/Desktop/scftisio/@CFITSIO_PREFIX@/lib -lcfitsio

Where -I/ specifies the path to some necessary files, and (I thought) -L specifies the path to the library folder where libcfitsio.a is (along with its contents, which I extracted to the same folder).

I have also tried setting LDFLAGS:

env LDFLAGS="-L/home/username/Desktop/scftisio/@CFITSIO_PREFIX@/lib"

However, no matter what I try, I consistently receive the above error.

I have tried creating symbolic links to libcfitsio in usr/lib, usr/lib64 and so on, but am unable to do so without root access. And unfortunately, I cannot get the root password for this lab.

For the same reason, I have been unable to edit ld.so.conf to include a path to my library.

Like I said, I'm probably making some stupid rookie mistake, can anyone point it out to me, or suggest a better approach that will avoid this error?

Simple solution

Ok, looks like this does the trick:

export LDFLAGS=/home/username/Desktop/scftisio/@CFITSIO_PREFIX@/lib

Silly me, that wasn't complicated.
