[igt-dev] [PATCH i-g-t v1] meson: missed dependency of liblzma

[Sergii Romantsov]

Failed to configure intel-gpu-tools with error:

	meson.build:151:0: ERROR:  Could not generate cargs for libdw:

libdw depends on liblzma.
Installation of liblzma-dev fixes issue.

Fixes: e39e09910fc8 (lib/core: Use libdw to decode stack trace with debugging symbols, v2.)

_We_ don't use liblzma for anything though, so this is kind of
superfluous. As I understood you, just installing liblzma-dev makes
the build successful, right? Making this change just lead to better
error messages when it's not installed?

What is the distro you're using? The ones we build-test on in gitlab
CI (Fedora, Debian) both have libdw's development package depend on
liblzma.

Hello, Petri.

If to be more specific, installing liblzma-dev makes meson-configuration
successful.

Yes, it will show which package exactly leaked instead of unclear error.

What is the distro you're using?

I think it happens due to specific of meson-dependency - how it looks for a
package.
So command (when liblzma-dev is absent, but liblzma5 is installed)
 'pkg-config --cflags --libs libdw'
gives:
"Package liblzma was not found in the pkg-config search path.
Perhaps you should add the directory containing `liblzma.pc'
to the PKG_CONFIG_PATH environment variable
Package 'liblzma', required by 'libdw', not found"

So in my understanding its just because of lack of liblzma.pc

Indeed. I checked Ubuntu 16.04's libdw-dev and it:

1) Has liblzma in Requires.private in libdw.pc
2) Does not depend on liblzma-dev

I don't see the bug reported, and I suspect it won't be fixed, with
16.04's support ending this year for the desktop version...


However, on the patch, I'll have to nak the meson.build change. Having
better error messages is not a good reason for useless dependency
declarations. I'll welcome a patch that makes dependency failures
point to the Dockerfiles, though.

[igt-dev] [PATCH i-g-t v2] meson: missed dependency of liblzma

[Sergii Romantsov]

Failed to configure intel-gpu-tools with error:

	meson.build:151:0: ERROR:  Could not generate cargs for libdw:

libdw depends on liblzma.
Installation of liblzma-dev fixes issue.
At least it has to be pointed in Readme.

v2: just readme updated

Seems it can be done with meson >= 0.50 - here we can dump a message if
dependency failure.
But it seems to be look as not good solution (one dependency - one message).

As i see in the Dockerfiles listed dependency on liblzma.
So if meson-change is not preferable in that case - so at least readme-file
has to point us about dependencies.
