It says, what exactly it writes. emacs
uses this backed of gconf
as the front-end communication with X, but as I was reading (over the Web), it needs also the dconf
.
So, try to install dconf and see if the message disappears.
yum install dconf dconf-editor
If you "Google" the warning message, you will find similar reports. Though I'm not sure if you need to report this as a bug (package maintain bug), where you will ask for dconf
to be included as a dependency for emacs.
When I use gcc, should I use -m64
option??
If you read the manual page for gcc
These -m switches are supported in
addition to the above on x86-64
processors in 64-bit environments.
-m32
-m64
-mx32
Generate code for a 32-bit or 64-bit environment. The -m32
option sets "int", "long", and pointer
types to 32 bits, and
generates code that runs on any i386 system.
The -m64 option sets "int" to 32 bits and "long" and pointer
types to 64 bits, and generates code
for the x86-64
architecture. For Darwin only the -m64 option also turns off
the -fno-pic and -mdynamic-no-pic
options.
so, do as you need.
