Use configure file to generate makefile

Question

I use ./configure command to generate a makefile. My compiler is arm-fsl-linux-gnueabi toochain. When I ran ./configure, I got the following problem:

tl@tl-virtual-machine:~/Desktop/mvux_camera/demo/sampli_save_demo$ ./configure --host=/home/tl/Desktop/opt/Embedsky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/arm-fsl-linux-gnueabi-g++ configure: WARNING: if you wanted to set the --build type, don't use --host.

My toolchain was sourced, when typing arm-fsl-linux-gnueabi-gcc -v , the command line shows it works.

Answer 1

Look at the output of ./configure --help , especially:

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

HOST should be the identity of the system on which you want your cross-compiled program to run. But you have set it to the absolute filename of your C++ compiler:

./configure --host=/home/tl/Desktop/opt/Embedsky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/arm-fsl-linux-gnueabi-g++

which results in your ./configure script attempting and failing to locate a cross-compiler with such nonsense names as:

/home/tl/Desktop/opt/Embedsky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/arm-fsl-linux-gnueabi-g++-g++
/home/tl/Desktop/opt/Embedsky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/arm-fsl-linux-gnueabi-g++-c++

Look at the output of arm-fsl-linux-gnueabi-gcc -v , specifically:

Target: arm-fsl-linux-gnueabi 

This tells you that your cross-compiler was built to cross-compile programs for arm-fsl-linux-gnueabi systems. Therefore, when you want to ./configure a project to use that cross-compiler, HOST = arm-fsl-linux-gnueabi
