Re: [dpdk-users] SW Turbo Poll Mode Driver

["Ginés García Avilés" <gines.garcia@i2cat.net>]

Hi again Nicolas,
Looking for a workaround trying to solve the previous issue,
I moved to Centos 7 (as suggested here 3. SW Turbo Poll Mode Driver — Data
Plane Development Kit 21.11.0-rc0 documentation (dpdk.org)
<https://doc.dpdk.org/guides/bbdevs/turbo_sw.html>)
and after having everything installed I found an *earlier issue*  when
compiling FlexRAN:

- FlexRAN-FEC-SDK-19-04/sdk/source/phy/lib_common/common_typedef_simd.hpp(43):
error: invalid redeclaration of type name "I16vec16" (declared at line 2528
of
"/opt/intel/oneapi/compiler/2021.4.0/linux/bin/intel64/../../compiler/include/dvec.h")

- FlexRAN-FEC-SDK-19-04/sdk/source/phy/lib_common/common_typedef_simd.hpp(153):
error: invalid redeclaration of type name "I32vec8" (declared at line 2259
of
"/opt/intel/oneapi/compiler/2021.4.0/linux/bin/intel64/../../compiler/include/dvec.h")

- FlexRAN-FEC-SDK-19-04/sdk/source/phy/lib_common/common_typedef_simd.hpp(191):
error: invalid redeclaration of type name "I8vec32" (declared at line 2872
of
"/opt/intel/oneapi/compiler/2021.4.0/linux/bin/intel64/../../compiler/include/dvec.h")

Versions:
  > icc (ICC) 2021.4.0 20210910
  > icpc (ICC) 2021.4.0 20210910
  > gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)
  > g++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

Steps:
  * Install Centos ICC dependencies
  * yum install intel-basekit intel-hpckit
  * . /opt/intel/oneapi/setvars.sh
 * cd <workspace>
  * ./FlexRAN-FEC-SDK19-04.sh
  * cd <workspace>/FlexRAN-FEC-SDK-19-04/sdk/
  * ./create-makefiles-linux.sh
  * cd build-avx512-icc
  * make

Am I missing something to compile flexRAN SDK?

Regards,
Ginés.
