From mboxrd@z Thu Jan 1 00:00:00 1970 From: Gary Bisson Date: Thu, 29 Oct 2015 21:06:49 +0100 Subject: [Buildroot] [PATCH 1/4] libfslcodec: add install hooks to fix libraries path In-Reply-To: <1446149212-12048-1-git-send-email-gary.bisson@boundarydevices.com> References: <1446149212-12048-1-git-send-email-gary.bisson@boundarydevices.com> Message-ID: <1446149212-12048-2-git-send-email-gary.bisson@boundarydevices.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net By default, all the libraries are installed under /usr/lib/imx-mm which causes problems at runtime. The hooks are inspired from the mechanism used in the Yocto recipe: https://github.com/Freescale/meta-fsl-arm/blob/fido/recipes- multimedia/libfslcodec/libfslcodec.inc This has been tested implicitely by running Gstreamer without any special setup (no ld.so.conf nor LD_LIBRARY_PATH modification): # gst-launch-0.10 playbin uri=file:///root/tears_of_steel_1080p.webm # gst-launch-0.10 audiotestsrc ! mfw_mp3encoder ! fakesink # gst-launch-1.0 playbin uri=file:///root/tears_of_steel_1080p.webm Signed-off-by: Gary Bisson --- Here are the dependencies the pipelines above are testing: $ for i in `find target/usr/lib/gstreamer*/*`; do readelf -d $i | grep NEEDED | grep lib_ && echo "($i)"; done 0x00000001 (NEEDED) Shared library: [lib_nb_amr_dec_arm9_elinux.so.2] 0x00000001 (NEEDED) Shared library: [lib_wb_amr_dec_arm9_elinux.so.2] (target/usr/lib/gstreamer-0.10/libmfw_gst_amrdec.so) 0x00000001 (NEEDED) Shared library: [lib_peq_arm11_elinux.so.1.fhw] (target/usr/lib/gstreamer-0.10/libmfw_gst_audio_pp.so) 0x00000001 (NEEDED) Shared library: [lib_mp3_enc_arm12_elinux.so.2] (target/usr/lib/gstreamer-0.10/libmfw_gst_mp3enc.so) 0x00000001 (NEEDED) Shared library: [lib_mp3_enc_arm12_elinux.so.2] (target/usr/lib/gstreamer-1.0/libgstimxaudio.so) Note that I added a staging install hook as well because otherwise the gst1-imx plugin doesn't find lib_mp3_enc_arm12_elinux.so at build time. Not to copy the same library twice I decided to go with a symlink. Let me know if that's acceptable.
