[dpdk-dev] [PATCH 0/3] fix test-meson-builds for older distros

[Bruce Richardson]

In order to ensure good test coverage, we sometimes need to run builds
on distros with older compilers, such as gcc 4.8 on RHEL/Centos 7. This
patchset does a small amount of clean-up to test-meson-builds.sh script
to allow it to be used for such gcc builds.

  devtools/test-meson-builds: support older compilers
  devtools/test-meson-builds: fix bash-isms

[dpdk-dev] [PATCH 1/3] devtools/test-meson-builds: skip missing compilers

[Bruce Richardson]

if either gcc or clang are missing, skip doing those builds.
This allows a setup to only do, e.g. gcc tests.

May I suggest this oneline change instead?

command -v $c >/dev/null 2>&1 || continue

Looks fine to me. Make the change on apply if you like, otherwise let me
know if you want a V2.

[dpdk-dev] [PATCH 2/3] devtools/test-meson-builds: support older compilers

[Bruce Richardson]

Older versions of GCC, such as on Redhat/CentOS 7, don't support
-march=nehalem, but need -march=corei7 instead.

[dpdk-dev] [PATCH 3/3] devtools/test-meson-builds: fix bash-isms

[Bruce Richardson]

The use of "==" is non-standard extension from bash, so use "="
for comparisons instead.

Applied with proposed change in patch 1, thanks.
