The equivalent (roughly) of a DLL is a shared library.
To make one, be sure to have gcc documentation handy. Any reasonable
distribution should have it. Try
from the commandline to get the standalone info browser, or

You must compile your C files position-independently. For example,
gcc -g -fPIC -o file.o -c file.c
g++ -g -fPIC -o file.o -c file.c
(depends on the language.)

(Still don't know how you guys define 'build'.)
You link a shared library consisting of the object file file1.o
file2.o about as follows.
gcc -shared -o program file1.o file2.o -llibrary1 -llibrary2
g++ -shared -fPIC -o program file1.o file2.o -llibrary1 -llibrary2
You need to pass -fPIC here because C++ linking requires compiling
internal extra files to have the global ctors called.

gdb is your program of choice. As always, `info gdb`. There is a
graphical frontend available, xxgdb, but I'm not used to it.

I'm afraid I can't help you with this (:-).

is a good starting point. I don't know of others as the extensive
documentation that comes with all the tools mostly sufficed. If it
doesn't, this newsgroup is a good place to ask.
