[Dev-C++] include of selfcreated libraries

[Frank W. <F.W...@wi...>]

Hello,

I wrote some classes that I don't want to include to new projekts every
time. So I created a directory ../inlcude and put in the foo.h files
containing the classes. Then I compiled the the foo.cpp building a
library named foo.a.
At the linker options I put in a -l foo.a but while compiling a new
projekt that sould use that new library I get a linker error.
What is neccessary to linkt the lib file? Is it neccessary to name the
libfile libfoo.a or someone else ??

Any suggestions?? Whats with the foo.so is this essential?

I hope somewone can give me a hint.

Greetings

Frank
