Description Paul Hewlett 2009-08-06 10:03:02 UTC

The configure script for module-init-tools fails on the target host string 'sh4-unknown-linux-gnu' even when setting 'ac_cv_host=yes'


Reproducible: Always

Steps to Reproduce:
1./usr/sh4-unknown-linux-gnu/xmerge -av1 module-init-tools

I am following the Gentoo Cross development guide at

http://www.gentoo.org/proj/en/base/embedded/handbook/index.xml?part=1&chap=1

Actual Results:  
This error originally occurred when executing:

/usr/sh4-unknown-linux-gnu/xmerge -av gentoo-sources

as described in the guide. This pulled in all the basic system tools such as findutils, coreutils and module-init-tools. (I have fixed other bugs that occurred with findutils and coreutils as described in other bug reports.)

The error is shown as:

dirac sh4-unknown-linux-gnu # /usr/sh4-unknown-linux-gnu/xmerge -av1 module-init-tools

Expected Results:  
module-init-tools should compile correctly

Comment 1 Paul Hewlett 2009-08-06 14:10:25 UTC

I have fixed this - some misunderstanding on my part.
Setting ac_cv_target=sh4-unknown-linux-gnu in my build environment solved the problem. The configure script for module-init-tools was executing

config.sub $target_alias

which is failing because target=unknown is passed to the configure script. Comparison with the configure script for coreutils shows that the coreutils configure script executes

config.sub $host_alias

which succeeds. Both the coreutils and module-init-tools configure scripts pass target=unknown on the command line - in module-init-tools this fails.

AFAICS, either the configure script for module-init-tools is calling config.sub incorrectly or the cross compilation environment is incorrectly passing target=unknown to the configure script.
 
Sorry about the noise.
