[Python-Dev] python3 k1om dissociation permanence (original) (raw)

Hello,

Enabling the build system for Intel MIC k1om is non-trivial using Python-3.4.4 Using Python2 for the k1om is very popular, but I require Python3 support on k1om.

The first requirement to complete this build involved the download and extraction of pre-built MPSS RPM's. Then built required host python bins using GCC. Lastly, build MIC bins using ICC. The exacts are appended to the end of this message.

I would like to discuss a few change requirements that trial and error has revealed.

1.) libffi requires the University OF Cantabria patch because the k1om is not binary compatible with x86_64. [attached]

These libffi changes could be implemented using the MIC or KNC macros. *see https://software.intel.com/en-us/node/514528

2.) ./configure script halts during failure to locate readelf for the host.

I simply commented out these lines in the ./configure file: #if test "$cross_compiling" = yes; then #case "$READELF" in #readelf|:) #as_fn_error $? "readelf for the host is required for cross builds" "$LINENO" 5 #;; #esac #fi

Ideally, ./configure would support ICC and k1om. Am I missing something in the configure/make commands below? Is it possible to bypass the readelf requirement when cross-compiling for k1om?

Additionally, are any of the command line parameters below unnecessary? PKG_CONFIG_LIBDIR PKG_CONFIG_PATH PYTHON_FOR_BUILD _PYTHON_HOST_PLATFORM HOSTPGEN HOSTARCH BUILDARCH

Thanks, Rob
