How do I turn off Makefile warnings?
If you have a Makefile that you can easily modify, you can supply different compiler flags to build each file. Disabling a particular warning is as easy as adding a -Wno- to the build line, for example: -Wno-unused-local-typedefs .
How do I disable werror?
Werror is a gcc argument, you cannot remove it directly via ./configure , otherwise an option like –disable-error would show up in the help text.
What does the option in GCC do?
When you invoke GCC, it normally does preprocessing, compilation, assembly and linking. The “overall options” allow you to stop this process at an intermediate stage. Then the output consists of object files output by the assembler. …
How to turn off warnings in GCC 4.2?
If the warning is controllable via a command line -W option, then you can (if you have GCC version 4.2 or newer) turn it off temporarily. First you need to find out what the option might be, then if it exists turn it off via a pragma. How you do this varies a bit with GCC version.
Is there a way to disable the calling stack in GCC?
Fairly recently (in 2014) gcc/g++ started adding a “calling-stack” to the messages, which gives the extra information. That relies upon a change to the preprocessor to track the line-numbers which can be turned off with a -P option (noted here ), but that appears to be incompletely integrated in a form which would suppress the calling-stack.
Why do I get error messages from GCC?
I’m working on a project that will read compiler error messages of a particular variety and do useful things with them. The sample codebase I’m testing this on (a random open-source application), and hence rebuilding frequently, contains a few bits that generate warnings, which are of no interest to me.
How are positive and negative options related in GCC?
The combined effect of positive and negative forms is that more specific options have priority over less specific ones, independently of their position in the command-line. For options of the same specificity, the last one takes effect.
