Subject: [dpdk-dev] [PATCH v2] devtools: control location of test builds
Date: Thu, 28 Nov 2019 00:00:55 +0100
Message-ID: <20191127230055.23608-1-thomas@monjalon.net> (raw)
In-Reply-To: <20191009101026.49019-1-bruce.richardson@intel.com>

From: Bruce Richardson <bruce.richardson@intel.com>

By default, both test-build.sh and test-meson-builds.sh scripts create the
builds they generate in the current working directory, leading to a large
number of build directories being present when testing patches. This
patchset modifies both scripts to use a DPDK_BUILD_TEST_DIR environment
variable to control where the build outputs are put.

For example, doing:
    export DPDK_BUILD_TEST_DIR=__builds
    ./devtools/test-meson-builds.sh && ./devtools/test-build.sh \
            x86_64-native-linux-clang+shared i686-native-linux-gcc

gives a "__builds" directory with 14 meson and 2 make builds (with the
meson build count depending on compiler availability)

 The script internally checks for dependencies, then builds for several
 combinations of compilation configuration.
+By default, each build will be put in a subfolder of the current working directory.
+However, if it is preferred to place the builds in a different location,
+the environment variable ``DPDK_BUILD_TEST_DIR`` can be set to that desired location.
+For example, setting ``DPDK_BUILD_TEST_DIR=__builds`` will put all builds
+in a single subfolder called "__builds" created in the current directory.
+Setting ``DPDK_BUILD_TEST_DIR`` to an absolute directory path e.g. ``/tmp`` is also supported.
