How to solve configure: Error: C compiler cannot create executables compilation Error

 

Compilation error:

[Sudo] password for ZYX:
The qpe program is already!
The Konqueror directory is already!
Build Konqueror, please wait...

ZYX @ ZYX:/opt/embedsky/QTE $

Train of Thought Analysis:
First, find some solutions on the Internet:
ZYX @ ZYX :~ $ Sudo apt-Get install build-essential
ZYX @ ZYX :~ $ Sudo apt-Get install libc6-dev
However, the error still exists after re-compilation. It does not seem to work.
I saw the second last sentence: "See 'config. log' For more details ."
Use the locate command to determine the location of config. log, as shown below.
ZYX @ ZYX:/$ locate config. Log

The first is the config. log directory.
ZYX @ ZYX:/$ CD/opt/embedsky/QTE/arm-qtopia-2.2.0/Konqueror/
ZYX @ ZYX:/opt/embedsky/QTE/arm-qtopia-2.2.0/Konqueror $ sudo gedit config. Log

The first line after config. log is opened ~ Row 3:
Configure: 2516: checking for C compiler version
Configure: 2519: Arm-Linux-GCC -- version </dev/null> & 5
./Configure: Line 2520: Arm-Linux-GCC: Command not found

We can find that the arm-Linux-GCC compiler is not found in the compilation script, but the cross compiler has been configured and takes effect. At this time, I remember that sometimes the compiler only has
Only the root user can be identified. Therefore, you can switch to the root user and run the compilation script again.

Solution:
ZYX @ ZYX:/opt/embedsky/QTE $ su
Password:
Root @ ZYX:/opt/embedsky/QTE #./arm-qtopia-2.2.0-konqueror_build

Done !!! Everything is OK !!!
