HI, guys,
I write a small program, named "ioprogram.c", with gnu readline library, refering various documentation on the Internet. however, gcc reports the following errors. what is my problem?
#include <readline/readline.h>
#include <stdio.h>
int main()
{
char* c = readline("");
int len = strlen(c);
for(int i=0; i<len; i++)
{
printf("%c", *(c+i));
fflush(stdout);
}
free(c);
}
gcc errors:
In file included from /usr/include/readline/readline.h:37,
from ioprogram.c:1:
/usr/include/readline/rltypedefs.h:65: error: expected ‘)’ before ‘*’ token

ioprogram.c: In function ‘main’:

Thanks in advance for any comments.
try compiling with
gcc ioprogram.c -o ioprogram -lreadline -lncurses

I try to execute the examle.cpp file of Project-OSRM. I did the following steps:
build OSRM from source as described here
in new terminal: cd osrm-backend/example
in the terminal: cmake ..
in the terminal: cmake --build .
in the terminal: sudo cmake --build . --target install
move the maps contractor, engine, extractor, partition, storage, util from /usr/local/include/osrm to /usr/local/include (else error maps are not in /usr/local/include)
in the terminal: g++ -std=c++11 example.cpp -o example
But I get the error
‘underlying_type_t’ in namespace ‘std’ does not name a template type
static_cast<std::underlying_type_t<RouteParameters::AnnotationsType>>
Does anyone have a idea what I'm doing wrong or what is going wrong and how to solve this?

underlying_type_t requires C++14. To be able to use it pass -std=c++14 to your compiler.
Don't forget to
#include <type_traits>
This missing directive also lead to the same (confusing) error message.
Good morning,

Is there someone that can help ?
Thanks
I was building Python (3.4 dev version) from source as a framework on OS X 10.8. I'm a relative newbie to Mac OS X internals and couldn't figure out why the OS X framework headers caused these errors. Can someone please give me some pointers?
I use the latest version of GNU gcc on my mac instead of the Apple supplied LLVM compiler. Perhaps, that's causing a compatibility problem.

The errors correspond precisely to the 'block' extension Apple developed for C, C++ and Objective-C languages. GCC (the GNU version) doesn't recognize the block occurences and complains.
I'm having serious problems running some standard commands such as sleep() with g++-mp-4.8 downloaded from macports. I don't have any of these problems compiling with llvm-g++-4.2.
This is quite annoying, because I'm trying to use C++11 features in this program.
Here is the read out from the compiler - I'm really sorry it's so long, I just have no idea what to do with it:

As suggested in the hints, I got rid of all the outdated -I/'s and set up the clang++ compiler as in Eclipse, Macos 10.8 and C++11
There were some clashes with between my code and the stl, but they were easy to hunt down from the console output.
i want to catch pipe() syscall, so i've changed source code in pipe.c
static pipe_hook_t pipe_hook;
pipe_hook_t set_pipe_hook(pipe_hook_t hook)
{
pipe_hook_t old_hook = pipe_hook;
pipe_hook = hook;
printk(KERN_INFO, "pipe hook: %p", hook);
return old_hook;
}
EXPORT_SYMBOL_GPL(set_pipe_hook);
then i tried to define pipe_hook_t in file syscalls.h (included in pipe.c)
typedef void (*pipe_hook_t)(int *filedes);
pipe_hook_t set_pipe_hook(pipe_hook_t hook);
and i have error:

fs/pipe.c:1131: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘set_pipe_hook’

fs/pipe.c:1154: error: implicit declaration of function ‘pipe_hook’
i've tried to create my own .h file and define pipe_hook_t there but the error was the same
Problem has been solved. I've just confused directory where header files are.
