Public bug reported:
Hello everybody,
Just in case where you are still facing to below issue and you are still
wondering how to solve that ?
I had faced to below linking error but only when I had tried to compile my
application with DPDK 17.11.4
Below the Virtual Machine configuration I had used :
Platform : VM
Architecture : x86_64 bits
Distrib : Ubuntu 18.04
GCC : 7.5.0
GLIBC : 2.27
Linux kernel version : 4.18.0-25-generic
/usr/lib/x86_64-linux-gnu/libmvec_nonshared.a(svml_finite_alias.oS): In
function `_ZGVbN2v___log_finite':
(.text+0x0): multiple definition of `_ZGVbN2v___log_finite'
/usr/lib/x86_64-linux-gnu/libmvec_nonshared.a(svml_finite_alias.oS):(.text+0x0):

collect2: error: ld returned 1 exit status
GNUmakefile:84: recipe for target 'my_app' failed
make: *** [my_app] Error 1
To solve that, I had proceeded as below :
***********************************************************************************************
cd dpdk-stable-17.11.4
rm -rf build/.config*
echo "CONFIG_RTE_LIBRTE_THUNDERX_NICVF_PMD=n" >>
config/defconfig_x86_64-native-linuxapp-gcc
make config T=x86_64-native-linuxapp-gcc
make
***********************************************************************************************
And when I had recompiled my app, it was working well.
Hoping it will be helpful.
