gzip's configure uses $SHELL to find a POSIX-compliant shell to put in the shebang of its shell scripts (zcat, gzexe, ...). However, we set $SHELL to /bin/bash in the Makefile, which may not be present on the target. We do make sure that /bin/sh always points to a valid shell on the target so we can use that. The configure discovery is completely broken for cross-compilation. The same $SHELL is used during the build (it is used by make to run the commands in rules) and on the target. Also, the checks for a valid shell use the host shell, not the target shell. We could try to patch gzip to fix that, but the checks can anyway not be run for the target shell, so we'll have to override it with a cache value anyway. So we can just as well do exactly that, without patching.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
