compile error 'siginfo_t' is not declared with gcc 4.8.2 on RedHat 6.4

[John Dubchak]

Hi,

I used the following configure statement to build the latest gcc 4.8.2, with C++ 11 support on RedHat 6.4, which came with the default installed gcc 4.4.7:

../configure --prefix=/usr/local/gcc-4.8.2 \
        --program-suffix=-48 \
        --enable-bootstrap \
	--enable-shared \
	--enable-threads=posix \
	--enable-checking=release \
	--with-system-zlib \
	--enable-__cxa_atexit \
	--enable-languages=c,c++ \
	--disable-multilib  \
        --with-tune=generic --with-arch_32=i686 --build=x86_64-redhat-linux

However, when I use the following compile command:

g++-48 -v -std=c++11 -c -I . -I /home/ec2-user/devel/cpp/projects-workspace/http/http-server/src -I /home/ec2-user/devel/cpp/jsoncpp-src-0.5.0/include -Wall  main.cpp -o main.o

I get this error:

In file included from main.cpp:14:
/usr/include/sys/wait.h:155:52: error: ‘siginfo_t’ has not been declared
 extern int waitid (idtype_t __idtype, __id_t __id, siginfo_t *__infop,
                                                    ^

The offending code looks like this:

#include <sys/wait.h>

static void sig_handler(int sig) {
    if (sig == SIGINT) {
        int status = 0;
        int savedErrno = errno;
        while (waitpid(-1, &status, WNOHANG) > 0)
            continue;
        errno = savedErrno;
    } else if (sig == SIGHUP) {
        int status = 0;
        int savedErrno = errno;
        while (waitpid(-1, &status, WNOHANG) > 0)
            continue;
        errno = savedErrno;
    }
}

I have spent a couple of days on this issue and can't really resolve it other than creating a typedef to workaround it, which I don't think is correct:

typedef siginfo_t int;

Is there a "proper" way to correct the error?  I have included the output of adding both -v and -E arguments to gcc [1].

Thanks,
John
