Hi Gines,
I don’t see such issue, you probably have to make sure libstdc++ is installed and accessible by meson.

Hi Nicolas,
thanks a lot for your help.

However, with the latest version of DPDK I'm still facing the following issue:
  - "drivers/baseband/turbo_sw/meson.build:13:4: ERROR: C library 'libstdc++' not found"

These are the steps I'm actually following for the whole process:
  - Set env vars (ICC compiler, FLEXRAN_SDK, DIR_WIRELESS_SDK, ...)
  - meson x86_64-native-linux-icc
  - cd x86_64-native-linux-icc
  - meson configure -Dflexran_sdk=xxx/build-avx512-icc/install
  - ninja

Thanks in advance,
Ginés.

Hi Gines,
The only thing is to make sure to set the meson option to point to the right location
See https://doc.dpdk.org/guides/bbdevs/turbo_sw.html : for instance something like this "meson configure -Dflexran_sdk=xxx/build-avx512-icc/install"
Then meson build framework will just link the libraries: see drivers\baseband\turbo_sw\meson.build which uses cc.find_library to dynamically find and link the libraries
