[Qemu-devel] [PATCH] Makefile: Make "install" depend on "trace-events-all"

[Qemu-devel] [PATCH] Makefile: Make "install" depend on "trace-events-all"

[Fam Zheng]

We install this file to data dir but since 0ab8ed18 it's no longer
required by any objects during "make". List it explicitly as a depended
target of install and fix the broken "make install" command.

I'm probably wrong, but I remember someone worked on making traces
self-descriptive, so that simpletrace would no longer need access to the
generated trace-events-all file.

If the file is really never used, then all stray rules to generate it should be
removed, as well as its installation.

Cheers,
  Lluis

It is used at runtime when analysing a simpletrace file. While it would
be nice if they were self-descriptive, that isn't the case today, so we
must install this file.

Are there plans to commit this change?

AFAICS, ToT builds are broken without this change.

Thanks,

Hi Doug,
I've been mostly offline due to illness but am back now.  The pull
request will be sent today.
