Subject: [dpdk-dev] [PATCH] devtools: fix 32-bits build
Date: Mon,  9 Nov 2020 13:00:35 +0000	[thread overview]
Message-ID: <20201109130035.3948462-1-ferruh.yigit@intel.com> (raw)

32 bit still uses the pkgconfig file for 64-bits libraries, from the
build log:

"
Using DPDK_TARGET i386-pc-linux-gnu
meson  -Dexamples=l3fwd --buildtype=debugoptimized --werror
-Dc_args=-m32 -Dc_link_args=-m32
/tmp/dpdk_maintain/self/dpdk/devtools/.. ./build-32b
...
Using 'PKG_CONFIG_PATH' from environment with value:
'/usr/local/lib64/pkgconfig/
"

This causes build error when linking with the found libraries.

Reproduced with 'librte_bpf' which only has 64 bit installed but still
enables building 'af_xdp' and link fails.

To fix updating 'PKG_CONFIG_PATH' and preventing 'load_env' overwrite
it.

Fixes: 9b83106d8784 ("devtools: test 32-bit build")

'build-32b' check inside the 'load_env' looks ugly but not sure how to
be sure 'PKG_CONFIG_PATH' set correct.
