If I select GNU toolchain to compile/build my software, does my software
have to be licensed under GNU?

Thanks.

Depends where the source for your application comes from. Why not
read the license?

No. It's perfectly legal to write proprietary software with open source
software.

The obligation to license under an open source license depends on using or
(possibly) linking to currently open source code and libraries. The
specific license will tell you what is required.

I am not a lawyer, and neither are most people who post here. You have asked
a legal question; my best advice is to ask a lawyer. However, given that I
cannot give you legal advice, here's my take on your question:

The compiler is licenced under the GPL, and the support libraries are
licenced under the LGPL.

If you include the compiler (whole, or in part) as an integral part of your
software, then you are bound by the licence for the compiler. Since the
compiler is licenced under the GPL, your code (*if* you derive your code
from the compiler, or encorporate parts of the compiler into your code)
must be GPL as well.

An example might be that your software project is an IDE with an integrated
java compiler derived from the GCC java compiler. For that project, you are
obliged to licence your software under the GPL (you are, after all, using
someone elses code; you are obliged to follow their licence).

If your software uses the support libraries, then you must provide the
support libraries under the LGPL licence. This does not affect the licence
for your software, but only the support libraries. *If* you make changes to
the support libraries, you must release those changes under the LGPL.

Other than that, you are free to choose whatever licence or licences you
want for your programs.

Thank you all for your response. I will do some homework based on the
information.
