Programs installed in the compiler's ia32 directory are not 32-bit

[Mick_Pont]

Some of the programs in the ia32 directory installed with recent
compiler versions are 64-bit programs, presumably by accident.

For example:

  % source /opt/intel/compilers_and_libraries_2016.1.150/linux/bin/compilervars.csh ia32
  % cd /opt/intel/compilers_and_libraries_2016.1.150/linux/bin/ia32
  % file ifort

  produces
    ifort: ELF 32-bit LSB executable, Intel 80386, ...

  but
  % file icc produces
    icc: ELF 64-bit LSB executable, x86-64, ...

So, on a machine with a 32-bit version of Linux installed, ifort works correctly
but icc does not work:

  icc: Exec format error. Wrong Architecture.

Using the "file" command on all the files in the ia32 directory shows
that 10 out of 17 files are 64-bit.

Thank you for notifying us about this. I will check into this and post after I know more.

I performed a variety of installations. From those I confirmed that on a 32-bit host only 32-bit executables are installed. Also, as you reported, on a 64-bit host the installation installs a blend of 32-bit and 64-bit executables in the ‘ia32’ directory. Those 64-bit executables are capable of generating 32-bit code/executables.
 
That blend will not support a usage scenario consisting of a 64-bit host serving as a tool repository for other systems that includes 32-bit systems, which I’m guessing must reflect your situation and how you became aware of this. Some options to work around this would be to host the IA32 tools from a 32-bit server for use on 32-bit systems, or install the tools locally on the 32-bit system for use locally.

I reported this to the Installation Developers for further investigation. I will let you know what I hear back.

Kevin - thanks for looking into it. Yes, our usage scenario is as you describe - a 64-bit machine hosting tools which are used on 32- and 64-bit machines

Kevin, here is an added twist. When Parallel Studio with C/C++ is installed on a 64-bit Windows system, there are two shortcuts to CMD batch files. Of these, "Compiler 16.0 Update 1 for IA-32 Visual Studio 2013 environment" actually calls the 32-bit cmd.exe in SysWow64, with arguments (among others) ""C:<install_dir>\compilers_and_libraries_2016.1.139\windows\bin\ipsxe-comp-vars.bat" ia32 vs2013". However, the path is set up in such a way that "icl" uses icl.exe in bin\intel64_ia32, which is a 64-bit PE32+ EXE! That is what caused problems when used from a remote 32-bit system.

There is a 32-bit icl.exe that exists in bin\ia32, but that never gets used. Does that file have any reason to exist on a 64-bit Windows system?

The layout of the compiler tools is quite different from that in earlier versions of Intel C than 16.0. An article about the changes and the rationale for the layout would be appreciated.

There is another unpleasant side effect from these changes: icl /Zi does not work in a 32-bit command window, whereas cl /Zi does, as reported in https://software.intel.com/en-us/forums/intel-c-compiler/topic/602255 . The problem is caused by the 64-bit Intel C compiler attempting to use the 32-bit MDPDBxxx.DLL found on PATH.

@Mick – Thank you for the confirmation.

@mecej4 – And a complicated one at that. I’ll dig into what you described, and reply again after I know more. The article, New Directory Layout for Intel® Parallel Studio XE 2016, offers an overview of the directory structure and benefits; it’s not detailed but hopefully it helps. There are additional benefits internally for us related to packaging across our various product offerings that share some components.

I'm migrating from "Intel(R) C Compiler XE for applications running on IA-32, Version 12.0.4.191 Build 20110427" to new compiler "Intel(R) C Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 16.0.3.210 Build 20160415". After installation, I discover that all the 32 bits library under the "compiler/lib/ia32/"  and 32 bits binary "bin/ia32/icc" are missing. Does the new version has these files, and if so where are they?

Is there a way to down load Intel(R) C Compiler XE for applications running on IA-32, Version 12.0.4.191 ?

You have the choice at install time of installing intel64 only, or both intel64 and ia32, the latter depending on a prior installation of 32-bit g++ and libraries.
