point to the referenced character. The following switches provide control over the error message format: -gnatvThe v stands for verbose. The effect of this setting is to write long-format error messages to stdout (the standard output file. The same program compiled with the -gnatv switch would generate: 3. funcion X (Q : Integer) | >>> Incorrect spelling of keyword "function" 4. return Integer; | >>> ";" should be "is" The vertical bar indicates the location of the error, and the >>> prefix can be used to search for error messages. When this switch is used the only source lines output are those with errors. -gnatlThe l stands for list. This switch causes a full listing of the file to be generated. The output might look as follows: 1. procedure E is 2. V : Integer; 3. funcion X (Q : Integer) | >>> Incorrect spelling of keyword "function" 4. return Integer; | >>> ";" should be "is" 5. begin 6. return Q + Q; 7. end; 8. begin 9. V := X + X; 10.end E; When you specify the -gnatv or -gnatl switches and standard output is redirected, a brief summary is written to stderr (standard error) giving the number of error messages and warning messages generated. -gnatUThis switch forces all error messages to be preceded by the unique string "error:". This means that error messages take a few more characters in space, but allows easy searching for and identification of error messages. -gnatbThe b stands for brief. This switch causes GNAT to generate the brief format error messages to stderr (the standard error file) as well as the verbose format message or full listing (which as usual is written to stdout (the standard output file). -gnatmnThe m stands for maximum. n is a decimal integer in the range of 1 to 999 and limits the number of error messages to be generated. For example, using -gnatm2 might yield e.adb:3:04: Incorrect spelling of keyw

For example, a very common compiler error messages format is: "filename:line_number:column_number: error message", e.g.: (From GCC): bad.c:1:10: syntax error, unexpected STRING (From a custom tool) input.dat:45:3: expected String_Literal, found ';', This is unambiguous when the input is a fixed 8-bit http://stackoverflow.com/questions/9744830/compiler-error-message-line-column-number-reporting-with-unicode encoding, such as ISO-8859-1. But when the input is Unicode (UTF-8, UTF-16, etc), what does (or should) "column" mean in this case? Which byte? Which code-point? Which grapheme? Is there any tool that sets a precedent choosing one or the other? unicode compiler-errors share|improve this question asked Mar 16 '12 at 21:37 wjl 4,4261527 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted A column should refer to non-combining Unicode code points. Both parts of a surrogate pair (in UTF-16) should share a column. A combining diacritical mark should share a column with the base character it modifies. This may apply to other non-spacing code points as well. share|improve this answer answered Mar 19 '12 at 11:16 Anthony Faull 10.1k42457 1 I think I found what I want that matches up with your answer as well. Extended grapheme clusters, as defined in unicode.org/reports/tr29 . I'm able to get at this through ICU's BreakIterator. –wjl Mar 19 '12 at 15:54 add a comment| up vote 0 down vote The GNU coding standards say that the Unicode character width should be used to calculate the column number: http://www.gnu.org/prep/standards/standards.html#Errors. This should be compatible to how Emacs, which consumes error messages, calculates

How i can get number line of error from gcc error line GCC ? If I compile my program and have more errors. How can i got its. Ex. after I compile source code and it have errors.

Can it get number from GCC direct ? Sorry I'm very poor in English. Thank you.

(Read 4657 times) Master Multiple posting newcomer Posts: 53 How to change the gcc build error messages format in codeblocks? « on: April 20, 2013, 12:34:13 pm » Hello every one,The subject is vague i know it , i couldn't just convey the meaning any better so i explain what i mean .according to http://gcc.gnu.org/wiki/ClangDiagnosticsComparison#fnref-c80f7dfc6950973199cc4f44ec4ae68de8e7cf2d : gcc now has a better Diagnostics , looking at the examples provided such as :Code: [Select]void foo(char **p, char **q)
{
(p - q)();
p();
}and trying to get the same thing in CB just fails , look at the error provided at gcc comparison page : Code: [Select]t.c:3:10: error: called object is not a function or function pointer
(p - q)();
^
t.c:4:4: error: called object ‘p' is not a function or function pointer
p();
^
t.c:1:17: note: declared here
void foo(char **p, char **q)
^and look at the error log generated inside CB : Code: [Select]C:\Users\Master\Documents\CodeBlocks\Test\main.cpp||In function 'void foo(char**, char**)':|
C:\Users\Master\Documents\CodeBlocks\Test\main.cpp|14|error: expression cannot be used as a function|
C:\Users\Master\Documents\CodeBlocks\Test\main.cpp|15|error: 'p' cannot be used as a function|
||=== Build finished: 2 errors, 0 warnings (0 minutes, 11 seconds) ===|
I am using the gcc 4.8, How can i achieve the same behavior in CB? is there any kind of settings i am missing here? « Last Edit: April 20, 2013, 12:37:07 pm by Master » Logged a man's dream is an index to his greatness... jens Administrator Lives here!
