Building an application on RedHat 7.2

["Neeraj Garg, Noida" <ngarg noida hcltech com>]

Hello everybody,

I am trying to port an application on linux. In the building process, i want
to use two step process:

g++ -nostdinc -MD  -O2 -funroll-loops -fforce-addr -Wall -W -Wpointer-arith
-Wno-unused  -I/usr/lib/gcc-lib/i386-redhat-linux/2.96/include
-I/usr/include -W -Wmissing-prototypes  -D__GCC32__  -c <src_file> -o
<object_file>

and then ld -L/usr/lib/gcc-lib/i386-redhat-linux/2.96/ -L/usr/lib -lpthread
-lstdc++ -lg++ -lgcc -lm -lc <all .o files> -o <a.out>
------------------------------
To remove the warning "ld: warning: cannot find entry symbol _start;
defaulting to 08048f58", i am adding following in ld command line:
/usr/lib/crt1.o /usr/lib/crti.o
/usr/lib/gcc-lib/i386-redhat-linux/2.96/crtbegin.o
/usr/lib/gcc-lib/i386-redhat-linux/2.96/crtend.o /usr/lib/crtn.o
---------------------------

Now a.out is successfully built. But now if am trying to execute it, it
gives me following error:
"bash: ../a.out: No such file or directory"

------------------------------------

Can anybody please tell me if i am supposed to include other linux standard
libraries to execute an a.out problem which is built using g++ and ld?
