#17735: OpenWRT fails to build host packages when CONFIG_SITE is defined
-------------------------+-----------------------------------
Reporter: luizluca@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Barrier Breaker 14.07
Component: base system | Version: Trunk
Keywords: |
-------------------------+-----------------------------------
On systems that defines CONFIG_SITE env var, OpenWRT cannot build packages
for host system (make package/xxx/host/compile). This happens on OpenSuSE
13.1, that has CONFIG_SITE=/usr/share/site/x86_64-unknown-linux-gnu by
default.
In OpenWRT, CONFIG_SITE defines some cached values for autoconf script, as
size of var types. This improves ./configure times.
When building packages to firmware target system, OpenWRT defines the
CONFIG_SITE to the correct target dependent config site file. For package
built for host system, I guess the CONFIG_SITE is not defined (as there is
no "configure: loading site script ..." msg in ./configure).
Whenever CONFIG_SITE is defined previously the make (as in OpenSuSE),
OpenWRT build scripts always redefine it to the target CONFIG_SITE. For
target builds, this is an expected behavior. However, when building for
host system, the usage of the target CONFIG_SITE will probably result in
unusable programs as the size of vars (like void*, long, etc) differs from
arch to arch.
So, OpenWRT build scripts should, alternatively:
a) not replace CONFIG_SITE when building host packages
b) unset CONFIG_SITE previously build
b) replace CONFIG_SITE to match host arch when building host packages
As an easy workaround, CONFIG_SITE can be unset previously make:
unset CONFIG_SITE; make
Setting CONFIG_SITE to empty value is not enough. It must be unset.
This affects BB and trunk but not AA.
