problem with spidev

Hello there,
I'm working on MangoPi-r3 based on F1C200S, I'm trying to communicate with TFT st7735r using spidev1.0
I wrote a code that working on RaspberryPi Zero and worked with the tft , but when I tried it on F1C200S it doesn't work , I think the problem in the spi driver
I also tried to run the spidev_test.c
https://github.com/rm-hull/spidev-test/blob/master/spidev_test.c

I was able to compile it but when trying to run it on F1C200S I got a strange message
/usr/lib/libc.so.6: version `GLIBC_2.33' not found

any help?

Re: problem with spidev

I build the image here
https://github.com/mangopi-sbc/buildroot-mangopi-r

the build system I used the default buildroot toolchain

I compiled the spidev_test.c with cross compiler: arm-linux-gnueabi-gcc
I tried another program using this cross compiler and it worked for me

└─$ arm-linux-gnueabi-gcc --version
