build error

[Prasun Ratn]

Hi

I am seeing a build error on the latest code (commit 4330a720d345a4374c3fbdc50abb1b7fb97bfd92)

The errors seem related to IntelPT and this is on a system without IntelPT.

$ git clone https://github.com/DynamoRIO/dynamorio.git
$ cd dynamorio/
$ git submodule init
$ git submodule update

$ mkdir build/
$ cd build/
$ cmake ../dynamorio/
$ make -j

Hi Prasun,

This may have started with https://github.com/DynamoRIO/dynamorio/commit/6f7f303abd3ecd1d6ffe07c68806bead83558bc9. I'll take a look. Thanks for the notification.

I could not reproduce this issue on my machine. libipt shouldn't require the presence of the intel-PT feature itself. I created https://github.com/DynamoRIO/dynamorio/issues/6043 for us to investigate.

Can you add more details of the build environment to https://github.com/DynamoRIO/dynamorio/issues/6043, to help us reproduce the issue?
