Gcc Error Messages Garbled

You are, for instance, trying to print a C++ std::string directly to printf. Both of them worked for me. To show the template structure more clearly, the templated type can also be printed as an indented text tree. As an aside, it would be really nice if emacs gave some way to inject these mouse events into its existing mouse handling infrastructure, but this is a start, at least. check over here

However, the LEA instruction's immediate values must not have this prefix: "lea %1(%2,%3,%4), %0" needs to become "lea 10(%rsi, %eax, 8), %edx"; the assembler rejects "lea $10(%rsi, %eax, $4), %edx". Hprint a memory address offset by 8; used for sse high-parts CAVEAT: Being undocumented, these format specifiers could theoretically change, but they seem to have held steady for quite a while In the following example, not only do we tell you that there is a problem with the * and point to it, we say exactly why and tell you what the However, sometimes very simple typedefs can wrap trivial types and it is important to strip off the typedef to understand what is going on.

Also, checking at runtime means that the program will stop on the first error it encounters, only displaying a single message. Sometimes GCC emits something that can be described as Haiku poems - and you have no clue as to what it really is complaining about. Case in point: I needed an efficient variant of the C/C++ strcmp function which operates on unsigned bytes and returns the length of the common prefix between its input strings, in i368/x86_64 has an especially rich set of constraints, due to its being both an extremely common compiler target and an uncommonly complex ISA Input/outputIs the operand input (default), output ("="), an

Other pernicious issues include the inability to recognize the [alt] key as a [meta], and inconsistent behavior between terminals on different machines. Example: create a directory and then change to it: $ mkdir ../../foo/bar/baz

$ cd !$
cd ../../foo/bar/baz

$ NOTE: I think there are a bunch of these, but I don't know Note that emacs-23 added a new terminal-specific key translation map, so you may have to change xterm-extras.el to use input-decode-map instead of funtion-key-map to get good results (or just use my For example, many distros set the locale environment variables (LC_*) in the .bashrc type startup files to something like en_US.UTF-8 by default.

Add a final return at the end of the function to solve this. Column Numbers and Caret Diagnostics First, all diagnostics produced by clang include full column number information. Naturally, the compiler can choose any mixture of legacy and 64-bit registers, so you can't just guess (plus, how do you get rid of the unwanted letters so you don't get https://gcc.gnu.org/ml/gcc-help/2006-08/msg00177.html Handling of immediate valuesImmediate values in x86 assembly usually need a '$' prefix and gcc dutifully emits this automatically (e.g. "add %1, %0" might become "add $1, %eax").

Until that happens, I suspect the patch will work for just about any version of xterm, but I've only tested it against xterm-261. But C++ templates are essentially just a mechanism for compile-time duck typing.

Fundamental to this algorithm is a measure for comparing correlations called the log-determinant (LogDet) divergence, and a primary contribution of this thesis is that of interpreting and analyzing this measure in http://digitalfanatics.org/resources/gcc-error-messages/ std::string foo;

c...like C, but print reversed condition F,f...likewise, but for floating-point. check my blog When gcc, MSVC, etc., were new, they couldn't afford to use lots of extra space to store data to produce better error messages. As you are using a forward declared type, GCC cannot tell if FooClass inherits the class implementing foo. To do this well requires black magic involving the flags register (which gcc's inline asm has virtually no support for), and treating registers as bytes and full words in turn.

Thanks to Diederik. Solution: tell gdb to keep its nose out of thread signals and let the pthreads library do its job. (gdb) handle SIG32 nostop noprint pass WARNING: Every time I have encountered Check for this. this content There is a way to reach the end of a non-void function without returning something.

Thanks. Warning: cannot pass objects of non-POD type ‘struct std::string' through ‘…' Warning message: cannot pass objects of non-POD type 'struct std::string' through '...'; call will abort at runtime. Useful Little Tricks Kill and signals Kill really just sends signals to processes; one of those signals happens to be KILL, but there are others, too.

For reasons I'll never understand, the vt200 (and therefore xterm) mouse escape sequence is totally non-standard and broken: "\e [ M b x y", where b, x, and y are arbitrary

Anyway, they didn't do it that way so we're stuck with terminals smaller than 224x224, and we get all kinds of problems in emacs as a result. Quoting this thread. If a C++ compiler hits a template error and gives you a stack trace, that would be just as unhelpful as "template vomit," wouldn't it? That triple-bucky C-M-s becomes 'ESC j s', file save becomes 'jxjs', etc.

Thanks to Diederik. I have a general idea of why template error messages in C++ are so bad. Some similar, useful commands are found at http://tldp.org/LDP/abs/html/refcards.html. have a peek at these guys With some code, the compiler can re-synchronize and diagnose real errors later in the code.

However, I got cygwin to work (sort of) at home and it does not have the problem even with LANG=en_US.utf8. This patch lets screen-4.0.3 recognize the "1005" CSI which enables extended mouse mode, and teaches it how to handle the extended mouse sequences which come as a result.

Is it plausible for my creature to have similar IQ as humans? Error: invalid operands of types `const char[31]' and `const char[7]' to binary `operator+' Error message: invalid operands of types `const char[31]' and `const char[7]' to binary `operator+'. Also using g++ command to compile the code. This can save a lot of repeated typing under some circumstances.

Git lets you edit these hunks manually for ultimate control, and it's a long-standing feature request for RecordExtension. It should have been something like "\e [ M pb ; px ; py m", where the p* are string representations of the desired numbers.

With traditional compilers, you need to dig deep into the definition of the macro to understand how you got into trouble. I ran into this problem when using a typedefed struct as a struct from a function.
