gcc error unrecognized option - warn-common Vidalia, Louisiana

could you explain me ? See the GNU CPP manual for details. -fcond-mismatch Allow conditional expressions with mismatched types in the second and third arguments. If installed as shared libraries they must be in the runtime linker's search path so they can be found. gcc) then all the linker command line options should be prefixed by -Wl, (or whatever is appropriate for the particular compiler driver) like this: gcc -Wl,--start-group foo.o bar.o -Wl,--end-groupThis is important,

GCOV/GCC data files are not created I found a bug in GCC 4.2 for Darwin (Apple System), should I report it? This option is useful when you have an undefined symbol in your link but don't know where the reference is coming from. -Y path Add path to the default library search The wrapper function should be called "__wrap_ symbol ". no checking for pgf95...

If it works, your code most probably has undefined behaviour because of some loop. My program invokes undefined behaviour but... [ Permalink ] Sorry, if your program invokes undefined behaviour, then: Anything at all can happen; the Standard imposes no requirements. Why must the speed of light be the universal speed limit for all the fundamental forces of nature? 5008 out of the box more hot questions question feed default about us Thank you so much! === UPDATE ==== Fixed with upgrade gcc from 4.4 to 4.7 http://ask.xmodulo.com/upgrade-gcc-centos.html centos g++ php-cpp share|improve this question edited Dec 8 '14 at 1:49 asked Dec 7

For options of the same specificity, the last one takes effect. This option tells ld that it should silently permit such possible errors. Note---if the linker is being invoked indirectly, via a compiler driver (e.g. I am forced to use source because rpm is also giving some problem and crashing while starting.

This type of archive searching is standard for Unix linkers. what is this error. Some options control the preprocessor and others the compiler itself. This warning is only issued if the base of the constant is ten.

yes checking whether gcc accepts -g... STRIP_STATIC="--strip-debug" #-- Manual (man and info) directories to compress (if zipman is specified) MAN_DIRS=({usr{,/local}{,/share},opt/*}/{man,info}) #-- Doc directories to remove (if !docs is specified) DOC_DIRS=(usr/{,local/}{,share/}{doc,gtk-doc} opt/*/{doc,gtk-doc}) #-- Files to be removed from May 2, 2011 Anyone else SUDDENLY getting this??? Finally, neither GCC bugzilla, nor GCC mailing lists are a forum appropriate to debate the above issues.

One or both of the two symbols will be a common symbol. 1. This warning is enabled by -Wall in C and C++. -Wmissing-bracesWarn if an aggregate or union initializer is not fully bracketed. If a -rpath option is used, the runtime search path will be formed exclusively using the -rpath options, ignoring the -L options. See Options Controlling C Dialect. -Wformat=1-WformatOption -Wformat is equivalent to -Wformat=1, and -Wno-format is equivalent to -Wformat=0.

style can be "uuid" to use 128 random bits, "sha1" to use a 160-bit SHA1 hash on the normative parts of the output contents, "md5" to use a 128-bit MD5 hash share|improve this answer answered Apr 21 '14 at 16:35 Netch 1,9541510 add a comment| up vote 2 down vote Use gcc -rdynamic or -Wl,--export-dynamic (the -Wl tells to send the next The formats are checked against the format features supported by GNU libc version 2.2. See the -( option for a way to force the linker to search archives multiple times.

Feb 17, 2010 I want to install php-soap on centos 5.2 server. This can be useful when creating a dynamic binary and it is known that all the shared libraries that it should be referencing are included on the linker's command line.

G++ 4.6 gave an error but it was changed to a warning intentionally for 4.7 because many people found that narrowing conversions were one of the most commonly encountered problems when

Higher levels correspond to higher accuracy (fewer false positives). It is ignored on targets that do not support this option. When an unrecognized warning option is requested (e.g., -Wunknown-warning), GCC emits a diagnostic stating that the option is not recognized. This is why we did not make -Wall request these warnings.

This option causes a warning to be issued whenever this case occurs. --warn-once Only warn once for each undefined symbol, rather than once per module which refers to it. --warn-section-align Warn Note: there should be no white space between sectionname, the equals sign ("="), and org. -Tbss=org -Tdata=org -Ttext=org Same as --section-start, with ".bss", ".data" or ".text" as the sectionname. -Ttext-segment=org When Likewise, .C refers to a literal capital C. Such files are also called specs.

pass_all checking how to run the C preprocessor... Examples of code with undefined behavior are a = a++;, a[n] = b[n++] and a[i++] = i;. Thus, in large programs, it is often necessary to use multiple global pointer values in order to be able to address all possible constants. Instead of the these attributes, it is also possible to add a "falls through" comment to silence the warning.

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. This option is available only for the i386 PE targeted port of the linker. Try adding -fno-lifetime-dse. This warning is enabled by -Wall. -Wcast-qualWarn whenever a pointer is cast so as to remove a type qualifier from the target type.

execstack Marks the object as requiring executable stack. here is my fdisk -l. Numeric arguments that are known to be bounded to a subrange of their type, or string arguments whose output is bounded either by their directive's precision or by a finite set Note---there is one exception to this rule.

Takes care of the common pun+dereference pattern in the front end: *(int*)&some_float. report-all Report all unresolved symbols. The One Definition Rule is relaxed for types without explicit visibility specifications which are defined in more than one different shared object: those declarations are permitted if they would have been This warning is also enabled by -Wall. -Wimplicit (C and Objective-C only)Same as -Wimplicit-int and -Wimplicit-function-declaration.

The compilation ended without errors and the program works, but it misses almost all toolbar and menu icons (only some common icons are there as open/save/copy/paste...) Is it because of this Floating-point results may still depend on the optimization level and target architecture in some cases that are allowed by the ISO C standard. E.g. It was created by epson-inkjet-printer-filter configure 1.0.0, which was generated by GNU Autoconf 2.61.

file.mm file.M Objective-C ++ source code. Note that those options are only available for ELF systems. --hash-size=number Set the default size of the linker's hash tables to a prime number close to number. This option is specific to VxWorks targets. -r --relocatable Generate relocatable output---i.e., generate an output file that can in turn serve as input to ld. This option may be specified more than once.

To compile 32-bit versions of the runtime libraries you need to have the 32-bit glibc headers installed, which are not installed by default on many GNU/Linux distributions. The default if neither flag is given to follow the standard, but to allow and give a warning for old-style code that would otherwise be invalid, or have different behavior. -fno-gnu-keywords file.mi Objective-C source code which should not be preprocessed. As a GNU extension, it is possible to allow their use in executable images as well, or to (probably pointlessly!) disallow it in object files, by using these two options.
