TL;DR: Add this to your command line Full explanation: I've managed to reproduce your issue on Ubuntu Jammy ❯ lsb_release -a

The Fortunately using these low level optimizations can be disabled in Boost, like this (of course this will not affect your actual build - only diagram generation): clang-uml -vvv --add-compile-flag "-DBOOST_UUID_NO_SIMD"You can also try to remove the include flags you added manually from the config and just run: clang-uml -vvv --query-driver . --add-compile-flag "-DBOOST_UUID_NO_SIMD"With the latter on my system I get the diagram: @startuml

Many thanks for the fast response. Unfortunately, it didn't solve the issue. I have appended the I have done some additional tests if I add the option Adding the compile flag solves the issue with |

@TheWorldOfCode Also, are you able to reproduce the problem using the above simple project, for instance by modifying the #include <QCoreApplication>
#include <boost/uuid/uuid.hpp>
#include <optional>
namespace my_app {
struct AAA {};
struct A {
boost::uuids::uuid tag;
void foo(const std::optional<AAA> arg1 = std::nullopt) {
}
};
struct B : public A {};
} // namespace my_app
int main(int argc, char *argv[]) {
QCoreApplication a(argc, argv);
return a.exec();

Hello
Clang UML is a great tool and I have been using it for a couple of years on work-related projects. We have just updated from Ubuntu Focal to Ubuntu Jammy.
On Ubuntu Jammy it complaining that it cannot locate cstddef when processing boost/uuid/uuid.hpp. When I attempt to solve the issue new errors are generated.
