Hi,
I tried ( CFLAGS="-march=x86_64 -pipe -ggdb"
CXXFLAGS="${CFLAGS}" ), but error comes:
======================================================
root@xxxxxxxxxxxxxxxxxxxxxxxxxxxx # ./configure
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for style of include used by make... GNU
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.
=======================================================
So I tried ( CFLAGS="-pipe -ggdb" CXXFLAGS="${CFLAGS}" ),
all the FLAGS in the Makefile was set to "-pipe -ggdb", as the
attachment showed..
Hmm, but there was still "??" in the back trace:
(gdb) bt

There is a exception when running my application with libceph, so I
need the stack in the libceph to point the problem. It's a little
URGENT...But I don't know what happened in the libceph, so
unlucky.....Here is my stack:
