 Posted: Tue Apr 27, 2004 7:24 am Post subject: Problem in installing icc (ifc) compiler |
 |
|
Dear Amd64 Gentooist,
Sorry for the "trivial" aspect of my questions.. but i am pretty new in Gentoo.
I use Gentoo (kernel 2.6.5) on an amd64 Opteron.
For some scientifical applications, i need to use the Intel compilers (icc) and (ifc) (in 32 bits mode).
I have emerged the corresponding icc ebuild (~x86) (version 8.0.055).
Everything worked perfectly... the directory /opt/intel/compiler80 is installed as the environement variables.
I installed the Intel non-commercial licences.
when i try to compile something:
~$ icc prog.cc -o a.out
i obtain the above results
/opt/intel/compiler80/bin/icc: line 4: /opt/intel/compiler80/bin/iccbin: cannot execute binary file
on line 4 of the /opt/intel/compiler80/bin/icc file the iccbin executable file is called.
the permissions are the following:
-rwxr-xr-x 1 root root 156 Apr 22 16:38 /opt/intel/compiler80/bin/icc
-rwxr-xr-x 1 root root 2467254 Apr 22 16:38 /opt/intel/compiler80/bin/iccbin
if i try to compile my prg using iccbin
~$ iccbin prog.cc -o a.out
I get this message:
-bash: /opt/intel/compiler80/bin/iccbin: cannot execute binary file
but if i try to get more informations about this executable using the "file" command, i get the following:
~$ file /opt/intel/compiler80/bin/iccbin
-->
/opt/intel/compiler80/bin/iccbin: ELF 64-bit LSB executable, IA-64 (Intel 64 bit architecture) version 1 (SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), not stripped
I really don't know how to solve the problem and what is exactly the problem ?!
Please, if you feel inspired don't hesitate to give me some ideas/suggestions.
thx you,
Trinakria
ps: i have the same pb with "ifc" compiler.
at the begining i thought it was a problem with the 32-bit emulation, but everything looks fine (32-emulation librairies and 32-bit emulation enabled in the kernel...) other 32-bit applications are working.. i really don't know what is the pb. |

Hello,
I turn to Intel fortran compiler (ifc)
I emerge the ifc (version: 7.0.064-r1)
iifc works....
well I can compile an object
$ ifc test.f90 -c
and if i try to link using the x86 (32-bit) emulation with
$ ifc -Wl,-m elf_i386 test.f90 -o a.out
->

it's better as before but still not so useful...
any idea for my compiler ? |

You made a mistake too install a 32bit compiler into a 64bit environment. That's not good (at least not good on Gentoo/amd64).
A much better approach would be to create a 32bit chroot, to compile all applications you need there and to copy them over to your 64bit env.
There's a guide to creation of 32bit chroot on
http://amd64.gentoo.org/technotes.xml

Is it impossible to install 32-bit program like compiler (icc/ifc) on Gentoo/amd64 ?
If i install a chroot environement is it possible to make it "user friendly" ? many users should have the possibility to use the compilers and run the executable in the 64-bit environement.
thx for your help |
