My question is in regards to compiler warnings generated by other people's code.

When I compile my programs, I often get compiler warnings like this:

Code: Select all

My question is about the "x is deprecated" warnings. I see that the compiler is telling me to use another procedure instead of the one in use. However, I did not write the code that is generating the warnings.

I am still new to open-sourced code. Is it "okay" to edit someone else's code, to get rid of those warnings? Or is that "trespassing"?

My Software Versions:
---------------------

CodeLite = 9.1.5
tdm-gcc = 5.1.0.3
Windows 7 = 6.1
wxWidgets = 3.1.0

You have to look at the license to know if you can edit those headers.

A local "workaround" is to tell to your compiler that there are system header, and so warnings from these headers are not reported:

For gcc/clang: use `-isystem` instead of `-I`.

See https://gcc.gnu.org/onlinedocs/cpp/System-Headers.html for more details.

Terrific! Thank you, Jarod42! That worked. Thank you also for the helpful link.
