Hi,
I am trying to cross compile DPDK for arm64 on a ubuntu
machine, which has a zlib pre-installed for native env.
I am encountering following build error in net_bnx2x as it has dependency on
zlib. It is trying to link with x86 arch based zlib.
Cross compiling zlib and setting the PKG_CONFIG_PATH solve the issue. But, Is
their an easy way to disable these dependencies?
b10814@dpdk-xeon:~/dpdk-up$ meson arm-build --cross-file
config/arm/arm64_armv8_linux_gcc
Configuration found that :
Run-time dependency zlib found: YES 1.2.11
(NOTE: it seems meson is detecting the default x86 based zlib for linking)
Note that this machine has ARM tool chain installed by Ubuntu
sudo apt-get install gcc-aarch64-linux-gnu
b10814@dpdk-xeon:~/dpdk-up$ ninja -C arm-build
