error: ‘__malloc_hook’ was not declared in this scope

[yummy527]

Help me with a new error. Sorry to bother you. I googled, but found nothing helpful. And not familiar with c++.

Thanks for reporting the issue. It is caused by the new version of glibc. I'll fix the package in a few minutes.

Oops. The issue has already been fixed.

https://github.com/m2-farzan/ros2-galactic-PKGBUILD/blob/b33f75c569c99a8a475eb892271abc30ab35802e/PKGBUILD#L77

It was first reported in https://github.com/m2-farzan/ros2-galactic-PKGBUILD/issues/19

I'm not sure why you're getting it though. Maybe the patching step has failed.

Try navigating to /home/wangxl/ros2_ws/src/ros2/realtime_support/ and running git log. You should see Remove the use of malloc hooks from the tlsf_cpp tests in HEAD. If not, it means that the patching was unsuccessful. Try makepkg --nobuild in a new directrory, and investigate terminal outputs, git logs, etc. Something is failing in the prepare step of the pkgbuild. Maybe a simple clean-build will fix it.

Succeed with a clean build, finally! And I notice that issue was triggered by repos of others(may be from here ), not your ros2-galactic-PKGBUILD. A little "dizzy" after trying these several versions and solving the bugs. Forgive me. Thanks for all your kind work and help.
