nginx module selection is, by default, the same as the one sets by the upstream configure script. Patches improving the cross-compilation support have already been sent upstream for integration [1-5]. All these patches are needed because nginx uses its own handwritten build-system, which is cross-platform, but does not properly support cross-compilation. Fixes bug: #3427 [6] [1] http://mailman.nginx.org/pipermail/nginx-devel/2014-August/005722.html [2] http://mailman.nginx.org/pipermail/nginx-devel/2014-August/005724.html [3] http://mailman.nginx.org/pipermail/nginx-devel/2014-August/005725.html [4] http://mailman.nginx.org/pipermail/nginx-devel/2014-August/005723.html [5] http://mailman.nginx.org/pipermail/nginx-devel/2014-August/005726.html [6] https://bugs.uclibc.org/show_bug.cgi?id=3427 Signed-off-by: Samuel Martin <s.martin49@gmail.com> Cc: Daniele Salvatore Albano <info@daccii.it> Cc: Maxime Hadjinlian <maxime.hadjinlian@gmail.com> Cc: Johan Oudinet <johan.oudinet@gmail.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Subject: [PATCH 1/5] auto/type/sizeof: rework autotest to be cross-compilation
|
|
friendly
|
|
|
|
Rework the sizeof test to do the checks at compile time instead of at
|
|
runtime. This way, it does not break when cross-compiling for a
|
|
different CPU architecture.
