I find that there are many info bellow in the configure file:
archive_expsym_cmds_CXX='$CC -shared $pic_flag $predep_objects
$libobjs $deplibs $postdep_objects $compiler_flags
${wl}-retain-symbols-file,$export_symbols -o $lib'
Is there some relation between this and "
${wl}-retain-symbols-file,$export_symbols -o $lib' "?
And in the ./libtool, there several line:
# Commands used to build and install a shared archive.
archive_cmds="\$CC -shared -nostdlib \$predep_objects \$libobjs
\$deplibs \$postdep_objects \$compiler_flags \${wl}-soname
\$wl\$soname -o \$lib"
archive_expsym_cmds="\$CC -shared -nostdlib \$predep_objects \$libobjs
\$deplibs \$postdep_objects \$compiler_flags \${wl}-soname
\$wl\$soname \${wl}-retain-symbols-file \$wl\$export_symbols -o \$lib"
postinstall_cmds=""
postuninstall_cmds=""
........... ...............
........... ...............
Well, after a try of deleting "\${wl}-retain-symbols-file
\$wl\$export_symbols" in libtool, then make install, the stack just
appear!!!!
(gdb) bt
#0 Client::write (this=0x629040, fd=10, buf=0x7fff2134cf10 "",
size=2097152, offset=0) at client/Client.cc:4999
#1 0x00007f739ca0922d in ceph_write (fd=10, buf=0x7fff2134cf10 "",
size=2097152, offset=0) at libceph.cc:322
#2 0x0000000000400fd3 in main (argc=1, argv=0x7fff2154d0d8) at testceph.cc:72
I think there should be a switch option of configure for
"\${wl}-retain-symbols-file \$wl\$export_symbols".
Hope helpful for all the user of ceph.
Thx you all!
