= Description ='install_cross_toolchain.sh armhf' will install the emdebian armhf toolchain,including the Debian package: libaio-dev:armhf.
|
|
In the process, this removes any other libaio-dev package installed in thecontainer. Almost all the files in these packages are identical (man pages, doc, and even /usr/include/libaio.h). However, the /usr/lib/<toolchain_or_arch>/libaio.so symlink is not.

In libaio-dev_0.3.110-1_armfs.deb, it has:{{{-rw-r--r-- root/root 11630 2014-10-09 04:32 ./usr/lib/arm-linux-gnueabihf/libaio.alrwxrwxrwx root/root 0 2014-10-09 04:32 ./usr/lib/arm-linux-gnueabihf/libaio.so -> /lib/arm-linux-gnueabihf/libaio.so.1.0.1}}}

Even though those these particular files (the most important ones) don't conflict, 'apt-get install' will automatically remove the otherpackage before installing the new one, due to overlap of the other files in the packages

'apt-get install' provides no support for overriding this autoremove functionality.

== idea 1 ==install it with dpkg instead of apt-get.
|

One possible workaround is to download the new package, and install it with dpkg (ignoring apt's dependencies).

A possible problem with this is if /usr/include/libaio.h ever differed between architectures. This file is sharedbetween all architectures, and would cause hard-to-find compilation problems between different arches.

Nope - that doesn't work (TRB: 2017-08-03). dpkg -i also deletes the other package.

== idea 2 ==extract only the .a and the .so link from the .deb, and install those
|
|
Write a custom tool to extract the items from the .deb that are uniqueto the libaio-dev package for a particular architecture, and install onlythose.

This ended up being the solution that worked. I put the support directlyinto install_cross_toolchain.sh. See that scriptfor details of the method used.

= Notes =This problem might crop up with other '-dev' packages. We shouldprobably see if there are other issues like this lurking with our useof emdebian toolchains.
