Question about GNU Lesser General Public License

[rotw]

Hello,

I have embedded in my FORTRAN main code a set of subroutines which are provided under Lesser General Public License. I intend to exploit the software code commercially and the source code is not to be disclosed. What are my legal obligations in this case?

- Am I required to provide the source code of the Lesser General Public License libraries/routines together with the main application closed source?
- Is it required to mention/reference the Lesser General Public License libraries being used (e.g. in software user agreement or alike place holder)

Please note that the source is compiled as DLL library.

In addition, I am curious - how do typically people find out about any (3rd party) external libraries being used as part of a main application, when they are not told so, if not by reverse engineering the main (obfuscated) code; however, this by itself constitutes a breach of terms of use unless done by someone legally authorized.

Thanks

I think you would only have to release the other code for the dll that you changed. As you haven't incorporated any of that code, you don't need to release your own code. Any changes to the other code require release as per the license since you modified it.

Understood, makes sense.
Thanks Agent666.

If you plan an escape, you must succeed as if you fail, you will be punished for trying. Never say or write down your plan. Heart is the only place where secrecy is granted.
