Hi there. I tried the following: export CPPFLAGS=' -stdlib=libc++ ' CXXFLAGS=' -stdlib=libc++ ' > meson build-clang > cd build-clang > ninja -j 4 >
and got such issues: > [213/2379] Compiling C object 'lib/76b5a35@@rte_bitratestats@sta > /librte_bitratestats_rte_bitrate.c.o'. > clang-11: warning: argument unused during compilation: '-stdlib=libc++' > [-Wunused-command-line-argument] > [219/2379] Compiling C object 'lib/76b5a35@@rte_cfgfile@sta > /librte_cfgfile_rte_cfgfile.c.o'. > clang-11: warning: argument unused during compilation: '-stdlib=libc++' > [-Wunused-command-line-argument] > [222/2379] Linking target lib/librte_acl.so.20.0.3. > FAILED: lib/librte_acl.so.20.0.3 > clang -o lib/librte_acl.so.20.0.3 > 'lib/76b5a35@@rte_acl@sta/librte_acl_acl_bld.c.o' > 'lib/76b5a35@@rte_acl@sta/librte_acl_acl_gen.c.o' 'lib/76b5a35@ > @rte_acl@sta/librte_acl_acl_run_scalar.c.o' > 'lib/76b5a35@@rte_acl@sta/librte_acl_rte_acl.c.o' > 'lib/76b5a35@@rte_acl@sta/librte_acl_tb_mem.c.o' > 'lib/76b5a35@@rte_acl@sta/librte_acl_acl_run_sse.c.o' > -Wl,--as-needed -Wl,--no-undefined -Wl,-O1 -shared -fPIC -Wl,--start-group > -Wl,-soname,librte_acl.so.20.0 -Wl,--no-as-needed -pthread -lm -ldl > lib/librte_eal.so.20.0.3 lib/librte_kvargs.so.20.0.3 > lib/librte_telemetry.so.20.0.3 -Wl,--end-group > -Wl,--version-script=/home/oceanfish81/dpdk-20.08/lib/librte_acl/rte_acl_version.map > '-Wl,-rpath,$ORIGIN/' > -Wl,-rpath-link,/home/oceanfish81/dpdk-20.08/build-clang/lib > /usr/bin/ld: > lib/76b5a35@@rte_acl@sta/librte_acl_rte_acl.c.o:(.data.rel.ro+0x18): > undefined reference to `rte_acl_classify_avx2' > clang-11: error: linker command failed with exit code 1 (use -v to see > invocation) > [225/2379] Generating bbdev.sym_chk with a meson_exe.py custom command. > ninja: build stopped: subcommand failed.
