My mkmf.log file looks like: https://photos-1.dropbox.com/t/0/AAC1TjDZ0BD6O3-NxkXZi3KbFo-c4o4Fgg6-Z9gAssWkcA/12/12846094/png/1024x768/3/1401408000/0/2/Screenshot%202014-05-29%2015.18.21.png/P6xlrS6O7FWpaZFZ6w7onpd2tRS5pyWoG4yO7D0hZV0 mislav commented Jun 1, 2014 @stantona: Compiling Nokogiri is different than compiling Ruby.
It is likely that you are trying to use the class Foo that you've forward declared but never included. GCC also warns about function definitions that might be candidates for format attributes. Using the command "make", one can automatically compile code and goto the position where the first error occurs. But this is totally wrong if we have clang installed, haven't set $CC, and are going to end up using gcc. http://web.ics.purdue.edu/~cs240/misc/errors.html
With this option, they are rejected. -Wpedantic does not cause warning messages for use of the alternate keywords whose names begin and end with ‘__’. The next lines indicate the errors/warnings that occur in that function and program file. For instance, warn about use of anonymous structures and unions, _Atomic type qualifier, _Thread_local storage-class specifier, _Alignas specifier, Alignof operator, _Generic keyword, and so on. Error: unable to find a register to spill in class `FOO' Error message: unable to find a register to spill in class `FOO'.
See Alternate Keywords. For C++, the warning is only emitted for scalar types or void. You may have used single quotes instead of double quotes for instance printf('x = %d', num); instead of printf("x = %d", num); warning: passing arg n of `XXXXX' makes pointer from Gcc Error Messages This warning is enabled by -Wall. -Wshift-count-negativeWarn if shift count is negative.
Not the answer you're looking for? Refer to this DevX article for an example of this. Check to make sure that you did not forget to send a format string to printf or scanf. https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html How?
They are much more difficult to get rid of than compiler and linker errors. Gcc Flags error: stray ‘\32' in program what does this mean and how do I fix it? But we can do better than before by approximating autoconf's choice of compiler as $CC if set, 'cc' otherwise (which will typically be a symlink to gcc or clang or another.) The whole body of the C or C++ style comment should match one of the following regular expressions: -fallthrough @[email protected] lint -fallthrough ? [ \t.!]*(ELSE,? |INTENTIONAL(LY)? )?FALL(S | |-)?THR(OUGH|U)[ \t.!]*(-[^\n\r]*)? [
If you're still building it for some reason, you might want to stop. http://askubuntu.com/questions/607691/gcc-fatal-error If a source file is changed between compiling with -fprofile-gen and with -fprofile-use, the files with the profile feedback can fail to match the source file and GCC cannot use the Gcc Warnings While enabling optimization will in most cases improve the accuracy of the warning, it may also result in false positives. -Wformat-length-Wformat-length=1Level 1 of -Wformat-length enabled by -Wformat employs a conservative approach Gcc Error Message Format I ran into this problem when using a typedefed struct as a struct from a function.
But this is totally wrong if we have clang installed, haven't set $CC, and are going to end up using gcc. Thank you. Note this option can only be used with the -Wuninitialized option. How does NumPy solve least squares for underdetermined systems? Gcc Errors List
This warning is also enabled by -Wextra. -Wignored-attributes (C and C++ only)Warn when an attribute is ignored. Gcc Fatal Error You might be able to work around the compiler bug by re-working your code, but it's not at all obvious how. case labels outside the enumeration range also provoke warnings when this option is used.
I'll post the answer. –mike Feb 13 '09 at 18:30 add a comment| up vote 1 down vote Seems like madness to me, but I just wanted to put in that Thus execute these commands. Incrementing a boolean is invalid in C++1z, and deprecated otherwise.) This warning is enabled by -Wall. -Wduplicated-condWarn about duplicated conditions in an if-else-if chain. Gcc #error However, be aware that your inline assembly may not run as fast as intended if you do this.
To suppress the warning, you need to provide a default case with assert(0) or similar code. lpar commented Mar 14, 2013 You don't even need to have clang installed to get the problem. This message can appear if you have forgotten a SIGNAL() or SLOT() macro when calling QObject::connect or a similar function. Quickfile Program Listing
Warns for all pointer conversions between possibly incompatible types, even if never dereferenced. The attributes currently supported are listed below. -Wsuggest-attribute=pure-Wsuggest-attribute=const-Wsuggest-attribute=noreturn Warn about functions that might be candidates for attributes pure, const or noreturn. However, it has many false positives. Thanks to Diederik.
