Cross-compile: How to install with one prefix, and deploy with a different prefix?

Question

I\'m trying to cross-compile some applications for an alternative architecture.

My typical procedure is as follows:

1. Download and untar source into /var/sou

Answer 1

If I understand correctly, /var/install on your x86 system will be / on your alternative architecture. To solve your issue, you need to modify the following step:

• configure will certainly do some sed in file, so you need to specify the final place

  ./configure --prefix=/ CC=[my-cross-compiler-gcc]

• makefile generated by automake have support of variable DESTDIR which is prepended to the installation path:

  make DESTDIR=/var/install install

Answer 2

I had a similar problem, but I was cross-compiling and wanted to install to the root directory of my device. In this case I specified:

make install DESTDIR=<path/to/rootfs>
