Is it very difficult to compile apps?

Well, you have to learn how 1st.

I recommend learning how to rebuild from src 1st out of the gate as the hardest part is done for you..
check dependencies
rpmbuild --rebuild packagename
install the rpm.

Then learn how to use a .tar app.
untar
read the readme & install; check rquired dependencies; then go to town.

Search this forum; it's all here & someone will help when you get in trouble.
