Bug#861073: libxinerama failed to cross build at configure
Source: libxinerama
Version: 2:1.1.3-1
Severity: normal
Tags: patch
Hi,
libxinerama fails when cross-compile with dpkg-buildpackage:
$ CONFIG_SITE=/etc/dpkg-cross/cross-config.armhf DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -aarmhf
By default, in configure, "malloc0returnsnull" is "auto" and it requires compile and run a test code
which cannot execute when cross build.
Error:
| checking whether malloc(0) returns NULL... configure: error: in `libxinerama-1.1.3/build':
| configure: error: cannot run test program while cross compiling
The cross-compile could pass if option "malloc0returnsnull" is specified ("enable" or "disable").
I think we could add this option to debian/rules. I've attached a patch for this.
In the patch, option "--disable-malloc0returnsnull" is default,
but option "--enable-malloc0returnsnull" will be called if
param "malloc0returnsnull" is passed to DEB_BUILD_OPTIONS.
Trung.
