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
