AN12195 Linux build error

[Enuwai]

Build toolchain according to "i.MX Yocto Project User's Guide" in "5.1.2. Setup aarch64 toolchain" section of AN12195
When I run "bitbake core-image-base", I get a lot of errors (some are excerpted below)
Do you know the solution?

Hi Qmiller

My development environment is:
　Ubuntu 18.04.1
　Yocto L4.9.51

AN12195 application note mentions Yocto version L4.9.51,
Is it better to use Ubuntu 20.04 and the latest Yocto?

Or is it better to use Ubuntu14.04?

Best Regards

You can try Ubuntu16.04, these error are caused by Ubuntu version of Host PC

Hi Qmiller,

I tried it on Ubuntu 16.04.7, but the following error occurred when executing the "repo init" command

unxp@U16047:~/imx-yocto-bsp$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest  -b imx-linux-morty -m imx-4.9.51-8mq_beta.xml

Tried on Ubuntu 20.04.5, repo init completes without issue.

However, when I run "bitbake core-image-base", I get the following error.

#error "Please port gnulib freadahead.c to your platform! Look at the definition of fflush, fread, ungetc on your system, then report this to bug-gnulib."
