Fortran Xcode Build setting for Big/Little Endian file conversion causes unrecognized keyword compiler error


Reference Number :  DPD200112282

Version :  11.0

Operating System :  Mac OS X* / IA-32, Intel® 64


Problem Description

On the Xcode Build tab, when using the Intel Fortran 11.0 (Preview) Xcode integrations, the text associated with the Big/Little Endian selections under the configuration setting Intel® Fortran Compiler 11.0 (Preview) > Compatibility > Unformatted File Conversion read correctly as follows:

Big Endian             ( -convert big_endian )
Little Endian          ( -convert little_endian )

While the text displays the accepted forms (with an underscore) of the argument to the associated -convert compiler option, the underlying mechanics of the Xcode integrations supply incorrect forms containing a hyphen (i.e. big-endian and little-endian) that the Intel Fortran compiler rejects.

Therefore, setting the unformatted file conversion build setting to either Big Endian or Little Endian results in these compilation errors under Xcode:

Error: Unrecognized keyword "big-endian" for option "-convert big-endian"
Error: Unrecognized keyword "little-endian" for option "-convert little-endian"


Resolution Status



This issue is resolved in the Intel Fortran Compiler Professional Edition 11.0 update, package id: m_cprof_p_11.0.064.

In lieu of installing the specific 11.0.064 update, to work around this issue, on the Xcode Build tab, set the Intel® Fortran Compiler 11.0 (Preview) > Compatibility > Unformatted File Conversion configuration setting to None and then add the explicit -convert option for the form of I/O conversion required for the application under the Intel® Fortran Compiler 11.0 (Preview) > Command Line > Additional options configuration setting.
