Something wrong with the libraries

[firedevel]

I didn't need extra features, so I modified the packages.sh: PACKAGES_TO_BUILD="update-libs update-binaries support jq avahi improv getevent ffmpeg shairport-sync"

but it gives an error when i run something on the speaker:

root@LX01-8083:~# shairport-sync shairport-sync: error while loading shared libraries: /usr/lib/libc.so: invalid ELF header

But the architecture seems correct: $ file '/home/ubuntu/ai/build/xiaoai-patch-master/squashfs-root/lib/libc.so' /home/ubuntu/ai/build/xiaoai-patch-master/squashfs-root/lib/libc.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, no section header

And LX01 has bluetooth but why it ignores building bluetooth support

packages/update-libs/package.mk: if [ "${BUILD_MODEL}" != "LX01" ]; then PACKAGE_DEPENDS="${PACKAGE_DEPENDS} bluez" fi

What's happens when generating dictionary s2t?

[duhow]

@firedevel have you extracted LX01 squashfs-root before building packages? This should define that the packages.sh MODEL is LX01 and will trigger the build for it, otherwise it will build for LX06, which has newer component versions and thus is incompatible with it.

Additionally, please confirm what firmware version are you using, and if you flashed the matching kernel partition as well.

[firedevel]

I tried extract squashfs to xiaoai-patch-master/squashfs-root first, but there is still the same problem

$ sudo docker run -it -v $PWD:/xiaoai xiaoai-patch
------------------------------------------------------------------------------
Host arch         :  x86_64
Target arch       :  armv7
Model detected    :  LX01
Prefix            :  /usr
Make concurrency  :  8

Note: Prefix will be the path to all binaries in target device 
------------------------------------------------------------------------------
Process will begin shortly. Press enter or break run (Ctrl+C). 

I've flashed the kernel image in ota file to kernel1, the xiaoai-patch-master/release/lx01/latest to rootfs1 and boot currently

[firedevel]

[duhow]

Got it, please note that current target recommended version for LX01 is 1.32.6 . During the build packages.sh process, if the model was previously wrong, you may need to rebuild all packages. Run sudo make clean-packages .

[firedevel]

Thanks, I tried to use 1.32.6, wifi_connect seems works fine, but there is still the same problem with shairport-sync

[firedevel]

Any solutions?

[duhow]

In short, you must keep the original /lib/libc.so from the firmware, and do not let the patch override that file with the text file you show. Additionally, the scripts will copy new libs built, but those should not override any of the existing (old) libraries.

What I don't understand is why you are seeing that text file...

[firedevel]

I found that squashfs-root/usr/lib/libc.so was fine in the latest build, but it was a text file in the previous build, maybe it was caused by an interruption during previous building?

I'll test the latest firmware when I have some free time, thanks for your reply.

[duhow]

I was able to reproduce the issue. Basically, the content is mainly stored in /lib, but system wants to check it in /usr/lib , which contains previous version and is not compatible. Workaround found is to override on run, but I will prepare some patching for this.

mount --bind /lib/libc-2.27.so /usr/lib/libc.so
mount --bind /lib/libuuid.so.1.3.0 /usr/lib/libuuid.so.1.3.0
