Disable Warning As Error Gcc

risky or suggest there may have been an error. The following language-independent options do not enable specific warnings but control the kinds of diagnostics produced by GCC.

-fsyntax-onlyCheck the code for syntax errors, but don't do anything beyond gcc disable warning for one line that. -fmax-errors=nLimits the maximum number of error messages to n, at which point GCC bails out rather gcc disable warning sign-compare than attempting to continue processing the source code. If n is 0 (the default), there is no limit on the number of error messages produced. If -Wfatal-errors is

also specified, then -Wfatal-errors takes precedence over this option. -wInhibit all warning messages. -WerrorMake all warnings into errors. -Werror=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. This switch takes a negative form, to be used to negate -Werror for

specific warnings; for example -Wno-error=switch makes -Wswitch warnings not be errors, even when -Werror is in effect. The warning message for each controllable warning includes the option that controls the warning. That option can then be used with -Werror= and -Wno-error= as described above. (Printing of the option in the warning message can be disabled using the -fno-diagnostics-show-option flag.) Note that specifying -Werror=foo automatically implies -Wfoo. However, -Wno-error=foo does not imply anything. -Wfatal-errorsThis option causes the compiler to abort compilation on the first error occurred rather than trying to keep going and printing further error messages. You can request many specific warnings with options beginning with ‘-W’, for example -Wimplicit to request warnings on implicit declarations. Each of these specific warning options also has a negative form beginning ‘-Wno-’ to turn off warnings; for example, -Wno-implicit. This manual lists only one of the two forms, whichever is not the default. For further language-specific options also refer to C++ Dialect Options and Objective-C and Objective-C++ Dialect Option

I get the following warning, which in turn causes the gcc or make to report an error: gcc -c -g -O2 -gnatpg -gnata -nostdinc -I- -I. -Iada -I../../gcc/ada ../../gcc/ada/exp_ch5.adb -o ada/exp_ch5.o exp_ch5.adb:177:16: warning: function "Has_Address_Clause" is not referenced make[2]: *** [ada/exp_ch5.o] Error 1 make[1]: *** [all-gcc] Error 2 make: *** [all] Error 2 Is there a way to instruct gcc or make to not fail on warnings? c gcc makefile ada share|improve http://stackoverflow.com/questions/2414242/gcc-make-how-to-disable-fail-on-warning this question asked Mar 10 '10 at 3:07 Dr. Watson 2,36032038 1 I don't think any of the debug options result in treating warnings as errors (at least not that I could find), is that the full output? –Tim Post♦ Mar 10 '10 at 3:15 add a comment| 7 Answers 7 active oldest votes up vote 5 down vote accepted The trigger here is the -gnatpg (actually, the -gnatg): this is the "GNAT implementation mode (used for compiling GNAT units)". -gnatp means "suppress all checks". I'm not sure of the full effect of -gnatg, though it certainly causes warnings to be treated as errors -- like -Werror -- at any rate while building the compiler itself; I think I remember seeing non-fatal warnings while building the RTS. One possibility would be to compile just exp_ch5.adb by hand without -gnatg; the command you list was issued at gcc/, so $ cd gcc $ gcc -c -g -O2 -gnatp -gnata -nostdinc -I- -I. -Iada -I../../gcc/ada ../../gcc/ada/exp_ch5.adb -o ada/exp_ch5.o Then back up one level, and 'make' again. This is a cross-compiler, so you won't (I hope!) need to repeat this for all three stages of a full build. share|improve this answer answered Mar 10 '10 at 21:10 Simon Wright 11.6k11326 Thank you, your solution allowed me to get past the above error.

However, it's possible. Set an environment variable: export CFLAGS = "-Wno-error" That's for for C compilers. If the project uses C++, do: export CXXFLAGS = "-Wno-error" In the very rare case the project does not honor this variables, your last resort is to edit the configure.ac file and search for -Werror and remove it from the string it occurs in (be careful though
