Problem with pthread library

[Chethan]

Hi

I am using LS1046a board, while building the yocto root file system using "flex-builder -i mkrfs -r yocto:devel -a arm64 -m ls1046ardb" in between i am getting error Please check below log of that.

"usr/aarch64-linux-gnu/lib/libpthread.so.0: undefined reference to `__libc_vfork@GLIBC_PRIVATE'"

Please throw some light to move forward 

Thanks & Regards

Please try to clean yocto build environment and rebuild the rootfs filesystem.

• flex-builder -i clean-rfs -r yocto:devel
• flex-builder -i mkrfs -r yocto:devel

Hi,

After trying with 

• flex-builder -i clean-rfs -r yocto:devel
• flex-builder -i mkrfs -r yocto:develI

I am getting same error.

Thanks & Regards
Chethan GR.

I created a clean LSDK 2004 build environment in my ubuntu 18.04 PC.

I generated Yocto:devel image successfully without any problem.

I suggest you prepare a clean ubuntu 18.04 environment, then download  LSDK 2004 to rebuild Yocto:devel rootfs image.

Hi,

After rebuild I am getting like this error
