Linux cross-compilation configuration and File System Configuration

1. The RedHat system profile file contains the following content:

# Path manipulation

If ['id-U' = 0]; then

Pathmunge/sbin

Pathmunge/usr/sbin

Pathmunge/usr/local/sbin

# Pathmunge/opt/embedsky/crosstool_3.4.5/gcc-3.4.5-glibc-2.3.6/ARM-Linux/bin

Pathmunge/pot/embedsky/4.3.3/bin

Fi

Select the cross-compiler version, and then source/etc/profile to make it take effect.

 

In the SuSE profile, because its path is output in append mode, you can set it in the following way:

# Path = $ path:/opt/embedsky/crosstools_3.4.5_softfloat/gcc-3.4.5-glibc-2.3.6/ARM-Linux/bin/
# Export path

 

Path = $ path:/opt/embedsky/4.3.3/bin/
Export path

 

# Export set Path =/sbin:/usr/local/sbin:/root/bin:/usr/local/bin:/usr/bin: /usr/lib/JVM/JRE/bin
You can use set path to restore the previous state and then append the cross compiler.
