[dpdk-stable-24.11.3] bbdev_trace.h: No such file or directory

[David Aldrich]

Hi
I am upgrading our DPDK-enabled app from dpdk-stable-23.11.1 to
dpdk-stable-24.11.3. With dpdk-stable-24.11.3 I get compilation error:

In file included from <snip>:
/opt/dpdk/dpdk-stable-24.11.3/install/include/rte_bbdev.h:36:10: fatal
error: bbdev_trace.h: No such file or directory

We use pkg-config to provide cflags:

$ pkg-config --cflags libdpdk
-I/opt/dpdk/dpdk-stable-24.11.3/install/include -include rte_config.h
-march=native -mrtm

but the path to bbdev_trace.h is not included:

$ find /opt/dpdk/dpdk-stable-24.11.3/ -name bbdev_trace.h
/opt/dpdk/dpdk-stable-24.11.3/lib/bbdev/bbdev_trace.h

Please suggest what is missing.

Best regards
David

Something is strange.
I see no reference to bbdev_trace.h in neither v24.11.3 tarball, nor
the 24.11 stable branch.
$ git grep bbdev_trace.h v24.11.3

It looks like you have some change in your dpdk copy, or I am missing
context to understand your report.

Which is expected.
bbdev_trace.h is a private header that is not exported.

Hi David

Thanks for your reply. I found that bbdev_trace.h is created by a
third-party patch I am required to apply, and it is not copied to the
install directory. My workaround is to manually copy it.
