petit_miner Posted January 26, 2019 Posted January 26, 2019 Hi there, I'm currently working on cross compiling libva-v4l2-request to test the VPU on the Allwinner V3s. I cloned the master branch from Github and told autoreconf to cross compile, but however it keeps looking for the wrong libva and libdrm libraries. Also everything with arm-linux-gnueabi fails somehow. I hope someone can help me with that. user@workpad:~/workspace/allwinnerV3s/libva-v4l2-request$ ./autogen.sh --host=arm-linux-gnueabi --build=x86_64-linux-gnu autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal autoreconf: configure.ac: tracing autoreconf: running: libtoolize --copy libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac, libtoolize: and rerunning libtoolize and aclocal. libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am. autoreconf: running: /usr/bin/autoconf autoreconf: running: /usr/bin/autoheader autoreconf: running: automake --add-missing --copy --no-force autoreconf: Leaving directory `.' checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for arm-linux-gnueabi-strip... no checking for strip... strip configure: WARNING: using cross tools not prefixed with host triplet checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking whether UID '1000' is supported by ustar format... yes checking whether GID '1000' is supported by ustar format... yes checking how to create a ustar tar archive... gnutar checking whether make supports nested variables...

JMCC Posted January 26, 2019 Posted January 26, 2019 Since these kind of libraries are not too big, I usually compile them natively on an ARM board. V3s' CPU may be a little too weak, but you can do it on any other armhf board you have, and it won't take more than a few minutes.
petit_miner Posted January 26, 2019 Author Posted January 26, 2019 Thanks, I will give it a try. Since this is a compiled library, where I should put the compiled files ? And do I have to create systemlinks or something similiar?
TonyMac32 Posted January 26, 2019 Posted January 26, 2019 Hello @petit_miner, How is the status of your hardware? Is it good enough to be built for evaluation? I want to do something similar, and have some V3s's laying about because of it that need a home.
petit_miner Posted January 27, 2019 Author Posted January 27, 2019 I think so, but I would suggest that you try the 4 Layer version. It has more interfaces (VGA out) and also uses 3 seperate DC DC step down modules which are easy to solder. I haven't tested the HDMI IN (ADV7611) yet, but every other interface works flawlessly. However I made a mistake while exporting the gerber files from eagle, the pcb misses the hole for the strain relief of the ethernet jack. It isn't that critical since the strain relief is made of plastic and you can easily cut it. If you want to I can sell you a bare PCB.
