[mpich-discuss] problem on mpich

[Rajeev Thakur]

The install directory that you specify in the --prefix option to
configure must be different from the directory where you are compiling
the source.
 
Separately, I would recommend using MPICH2 instead of MPICH 1.2.7, which
is very old.

Subject: [mpich-discuss] problem on mpich


Dear all

I am new to linux, here I met a problem when I compile mpich-1.2.7 on
FC10. 

My system environment is:
gcc version 4.4.1 (GCC)
pgf90 7.0-5 64-bit target on x86-64 Linux

The problem is
 if [ "" = "" ] ; then \
        ./bin/mpiinstall  ; \
    else \
        ./bin/mpiinstall -prefix=  ; \
    fi
cp: `/home/jy/espresso/mpich-1.2.7p1/bin/tarch' and
`/home/jy/espresso/mpich-1.2.7p1/bin/tarch' are the same file
**Error copying file /home/jy/espresso/mpich-1.2.7p1/bin/tarch to
/home/jy/espresso/mpich-1.2.7p1/bin/tarch **
make: *** [install] Error 1

I met this problem when I type in make install. What's wrong with it?
Thank you in advance.

Sincerely

Jiaye
