Hi Nicolas, thanks a lot for your reply. I'm trying to build DPDK with ICC but I'm not sure why libstdc++ is not accessible for meson. As a workaround, I'm checking gcc in order to see whether the installation is correct or not (as far as I know icc takes some info from gcc).
As an alternative, If I move to gcc as the compiler used by meson, I'm getting the following error for each operation provided by FlexRAN: - "libldpc_encoder_5gnr.a(phy_ldpc_encoder_5gnr.cpp.o): relocation R_X86_64_32S against `.rodata.str1.32' can not be used when making a shared object; recompile with -fPIC" I have checked the fPIC flag and it is already included when compiling the turbo_sw driver. - Versions: > FlexRAN 19.04 > DPDK 21.08 > gcc Ubuntu 9.3.0 > Ubuntu 20.04 Should I use gcc or icc for compiling dpdk? Any ideas about what could be the issue in the previous environments? Thanks a lot in advance, Ginés.
