Common issues and how to troubleshoot them
Deleted the install/ folder, now I can't rebuild !
Fix: open a new terminal without loading the env.sh script,
into the root of the workspace and run
install/ folder contains all the non-OS dependencies (e.g.
RubyGems, pip, …). You need to reinstall them before you can successfully
A package is always rebuilt, regardless of whether it is needed or not
Autoproj determines whether a package needs to be rebuilt by looking at the newest file in the package's source tree. It has a built-in ignore set of patterns to avoid rebuilding for e.g. changes in Git configuration, but sometimes packages modify files in their source tree for which Autoproj does not have an exclude.
You can troubleshoot this by building the offending package with
amake planning/omplapp --debug
In the generated output, look for a line that looks like:
getting tree timestamp for /home/doudou/dev/squidbot/planning/omplapp
and then the nearest line afterwards that looks like:
newest file: /home/doudou/dev/squidbot/planning/omplapp/src/omplapp/config.h at 2019-01-30 15:48:15 -0200
That's the offending file. It's now up to you to decide whether the best is changing the package's build system to avoid doing this, or to add an exception in the package's autobuild definition with
cmake_package 'planning/omplapp' do |pkg|
pkg.source_tree_excludes << File.join(pkg.srcdir, 'src', 'omplapp', 'config.h')
