Hi there,
I am trying to add Mosquitto (MQTT) as a cheribuild target. This is my current Python script:
from .crosscompileproject import CrossCompileCMakeProject, GitRepositoryfrom ...config.compilation_targets import CompilationTargets
class BuildMqtt(CrossCompileCMakeProject): target = "mqtt" repository = GitRepository("">github.com/.../mosquitto") supported_architectures = CompilationTargets.ALL_FREEBSD_AND_CHERIBSD_TARGETS + [CompilationTargets.NATIVE]
When running ./cheribuild mqtt-morello-purecap to build the target, I run into this error message:
CMake Error at man/CMakeLists.txt:29 (message): xsltproc not found: manpages cannot be built
-- Configuring incomplete, errors occurred!
Looking at the MQTT Git repository here and in the "Building from source" section, I can add the CMake option "WITH_DOCS=no" which disables checking for the optional build dependency xsltproc to generate man pages which I don't need. With these changes my build script now looks like this:
def setup(self): super().setup() self.add_cmake_options(WITH_DOCS=no)
Now when I attempt to run ./cheribuild.py mqtt-morello-purecap again, I am presented with multiple errors:
Traceback (most recent call last): File "./cheribuild.py", line 42, in <module> main() File "/home/ubuntu/cheribuild/pycheribuild/__main__.py", line 258, in main run_and_kill_children_on_exit(real_main) File "/home/ubuntu/cheribuild/pycheribuild/processutils.py", line 771, in run_and_kill_children_on_exit fn() File "/home/ubuntu/cheribuild/pycheribuild/__main__.py", line 248, in real_main target_manager.run(cheri_config) File "/home/ubuntu/cheribuild/pycheribuild/targets.py", line 435, in run target.execute(config) File "/home/ubuntu/cheribuild/pycheribuild/targets.py", line 129, in execute self._do_run(config, msg="Built", func=lambda project: project.process()) File "/home/ubuntu/cheribuild/pycheribuild/targets.py", line 107, in _do_run project.setup() File "/home/ubuntu/cheribuild/pycheribuild/projects/cross/mqtt.py", line 11, in setup self.add_cmake_options(WITH_DOCS=no)NameError: name 'no' is not defined
Any ideas why this section below in particular is occurring? Or any ideas on how to skip the checking for the xsltproc optional dependency?

Thanks!
That is far from a fix, and may be causing subtle mis-compiles. The correct thing to do is to find out what the test is doing, find out what variable it's using for the test result and manually specify the value for the variable so the test is skipped, normally via something like self.add_configure_vars(ac_cv_foo="bar") in your target's setup function.
