During uboot compilation, it is displayed that arm-linux-gcc is not found.

During uboot compilation, it is displayed that you cannot find the information about arm-linux-gcc-general Linux technology-Linux technology and application. The following is a detailed description. I run these

It should indicate that the compiler has been installed successfully, but why does this error occur when I compile uboot?
[Root @ localhost u-boot-1.1.6] # make all
Make:/opt/EmbedSky/crosstools_3.4.5_softflat/gcc-3.4.5-glibc-2.3.6/arm-linux/bin/arm-linux-gcc: Command not found

May I ask you?
