Installation of Fortran and C++ compilers on Core-i7 using Cent OS Linux

[deutschf]

Dear all,

I am very new to this and hope that someone would have an answer for me.

I have been trying to install Fortran and C++ compilers on my Linux (Cent OS).

Following the instruction for download and unpack the compilers, I have successfully followed up until the installation part.

When I used the ./install.sh The screen indicated that the architecture is not supported or different.

My computer is run on core-i7, so I am not sure if this is the problem with the core-i7 or the Cent OS Linux.

Or if there is any library or required files to be installed prior to these compilers.

Anyone have any idea? Please help....

The compilers and Centos can be either 32-bit or 64-bit versions. Each OS/compiler combination has to meet a few simple prerequisites that are described in the release notes and installation instructions for the compilers.

Once in a while a user tries to install an IA64 version of the compiler on an AMD64/EM64T/Intel64 system, having confused IA64 with X64.

Please report the output of uname -a on your Centos system, the output of rpm -qa glibc* , and the name of the downloaded Intel compiler distribution file, e.g., l_cprof_p_11.1.073.tgz .

Dear mecej4

I have done what you suggsted.

- Linux localhost.localdomain 2.6.18-194.17.1.el5PAE # 1 SMP Wed Sep 29 13:31:51 EDT 2010 i686 i686 i386 GNU/LINUX

- glibc-2.5.-49.el5_5_5

- l_cprof_p_11.1.073_intel64

- l_cproc_p_11.1.073_intel64

Actually I have tired both version, IA64 and intel64

But both doesn't work saying that the system architecture are not correct or something like that.

Under the 32-bit CentOS you have installed, only the ia32 version of ifort will work. You could change your OS to similar x86_64 version, then both the intel64 and ia32 ifort will work, the first with a g++ (64-bit) development system installed, the latter requiring also the g++ 32-bit (possibly called "legacy" development system). "Compatibility" libstdc++-33 libraries, both 32- and 64-bit, also are required, until the next major release of ifort.
Additional possible complications for installation of the gui debugger idb: you may have to remove a symlink, if 'java -version' is linked to gcj, and then install the 32-bit Sun jre (64-bit jre if you change to 64-bit OS), with certain CentOS versions. While it may not be clear, failing to install the jre prerequisite will not interfere with running the compiler and command line debugger idbc.

Thank you very much. I will try to reinstall Cent OS for x64 version and try to install compilers again.

Very appreciate your answer :)
