ioctl(socketDescriptor, SIOCGIFCONF, &ifconf)
This ioctl call works fine when I use it in normal RTP, but gives the following error when used in .a libraries.
ENXIO i.e. "this driver or device was not found".
this is because the vxWorks has changed the underlying implementation of ioct(SIOCGIFCONFIG) form vxWorks 6.9.3 to vxWorks 6.9.4.6

From the linux console I run a windows console tool using:
wine console_tool.exe ....
The console tool does not involve any windows. It's output is just textual.
Some output is added repeatedly after a given delay time.
However, besides the output of the console_tool.exe I get repeatedly the following error message also interleaved with the other output:
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
I already tried to export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0 but then the only change is that the error message changes:
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.
I also attempted to apt install the :i386 version of the libgtk3-nocsd.so.0 but it doesn't seem to exists.
I don't know why a console application may trigger a gtk error message. This is beyond my knowledge.
My preferred goal would be to tell wine that the .exe does not use windows and it does not need to not use gtk for windows emulation at all. However, as this may not be possible, my second preferred goal would be to solve the gtk issue.
Can you help me achieve at least one of those goals?
I do not know what the error messages mean. However, the wineconsole command runs console executable using wine. Example:
wineconsole console_tool.exe
I am trying to Interface a BLE module based on Nordic's nrf52840 to a Yocto based SBC, to which all the BlueZ related packages have been added.
I have flashed Zephyr's sample hci_uart program onto the module. The module seems to run perfectly on my Linux PC (BlueZ version 5.48), whereas on the SBC(BlueZ version 5.54) it fails to get inited. Here's the error that comes when I use
root#rb-imx6:~# hciconfig hci0 up
root#rb-imx6:~# Can't init device hci0: Cannot assign requested address (99)
Can anyone please help me out on this?
Thanks in advance.
The error of assigning an address is caused by missing Linux kernel configuration options:
CONFIG_CRYPTO_USER
CONFIG_CRYPTO_USER_API
CONFIG_CRYPTO_USER_API_AEAD
CONFIG_CRYPTO_USER_API_HASH
CONFIG_CRYPTO_AES
CONFIG_CRYPTO_CCM
CONFIG_CRYPTO_AEAD
CONFIG_CRYPTO_CMAC
This is likely to happen with a self-built Buildroot or Yocto Embedded Linux system. If you run into this error, you should enable above options and recompile the kernel.
See the BlueZ requirements here: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/README#n64
To see detailed debug output from BlueZ, run it with -d option:
bluetoothd -d
I used to programing my uCu before but now I have very weird error. It seems to be problem with programmer but I'm not sure. Avrdude throws this error:
C:\Users\Adam>avrdude -p m328p -c avrispmkII
avrdude: ser_open(): can't open device "\.\com1": The system cannot find the file specified.
and atmel studio this

I have tried use different ports but it didn't help. Device Menager said I already have good driver. Please help me find the solution.

I'm trying to use I2S (not I2C) with the Teensy LC and a SPH0645 digital microphone. The audio library that is included with the Teensyduino (v1.6.7 and ArduinoIDE 1.8.5) code is sufficient for my needs, but I get the following assembler error when I try to compile the Recorder example from the audio library:

My problem apart from the error is that the message doesn't indicate which file is the culprit. So I was hoping someone maybe has some more experience with this kind of problem ;)
I installed HTK tookit. It was happened when I terminated “hslab yes.sig” command line on win10 system.
The following the error :
ERROR [+6006] StartAudi: Requested data format is not supported [ERR=2]
FATAL ERROR - Terminating program hslab
Who can give a advice? Very thanks!
I suggest not using hslab in windows environment. U can use SFS (speech filling system) and better recording apps, like cooledit or another 3rd party, or event internal win. sound recorder
