How do you treat all warnings as errors in GCC?
Make all warnings into errors. Make the specified warning into an error. The specifier for a warning is appended; for example -Werror=switch turns the warnings controlled by -Wswitch into errors.
What is Fpermissive C++?
The -fpermissive flag causes the compiler to report some things that are actually errors (but are permitted by some compilers) as warnings, to permit code to compile even if it doesn’t conform to the language rules. Thus, using -fpermissive will allow some nonconforming code to compile.
What is gcc error?
Errors report problems that make it impossible to compile your program. GCC reports errors with the source file name and line number where the problem is apparent. Warnings report other unusual conditions in your code that may indicate a problem, although compilation can (and does) proceed.
What does [- Fpermissive mean?
The -fpermissive flag causes the compiler to report some things that are actually errors (but are permitted by some compilers) as warnings, to permit code to compile even if it doesn’t conform to the language rules.
How to treat a warning as an error?
You can make all warnings being treated as such using -Wno-error. You can make specific warnings being treated as such by using -Wno-error= where is the name of the warning you don’t want treated as an error.
How to compile without warnings being treated as errors?
Then warnings will be only warnings. You can make all warnings being treated as such using -Wno-error. You can make specific warnings being treated as such by using -Wno-error= where is the name of the warning you don’t want treated as an error.
How to fix GCC warnings being treated as errors?
The compiler is CodeSourcery ARM. You need to remove -Werror from CFLAGS, CPPFLAGS etc.; these are usually set in Makefile’s or build scripts. However, I’d strongly advice to fix the actual warnings instead, which will produce more stable and error-free code.
