GNU GPL license is required - commercial use is not viable?

First of all, thank you for this project.

I tried all the different configuration and quickly found out that this project cannot be integrated into a commercial project because of the libraries that read the debug info (if we discount the backtrace_symbols API, which can easily be used directly, but provides very little information).

• libbfd is GPL
• libdw is GPL
• libdwarf is is fine to use in a commercial project but requires libelf to be linked, which is GPL

I am not a legal guru, I do code, but my conclusion is that our project cannot use this project without transitively poisoning itself with GPL's obligation to make our codebase public to our customers.

Has anybody looked into this? Am I missing something? Is it possible to integrate non-GPL, but similarly powerful debug info reader?

libelf is dual licensed GPL and LGPL :)

Ah, I see. Thank you.

For others, my link to libelf in the original post is incorrect. This is the correct one.
