Native dependency 'fuse3' not found

[ob-ivan]

I'm running Fedora 26 with 4.12.14-300 kernel on x86_64 arch. I've just installed fuse3 following instructions at https://github.com/libfuse/libfuse. Tests were all green. The only issue I've encountered was that /etc/init.d/fuse3 didn't support chkconfig, and I sort of fixed that manually by adding:

# chkconfig: - 90 60

at the top of the script, then running all sorts of chkconfig --add fuse3, chkconfig fuse3 on, systemctl start fuse3 to get it up.

Now I try to install sshfs, and when I run meson .., this is what I get:

Meson encountered an error in file meson.build, line 47, column 0:
Native dependency 'fuse3' not found

Yet, fuse3 service seems to be up and running:

[ivan@fedora build]$ sudo systemctl status fuse3

What could I have possibly done wrong? And how do I do it right?

What does pkg-config --modversion fuse3 say? If it gives you an error, then this is the source of your problem. Maybe pkg-config doesn't look for the fuse3.pc file in the place where Meson has installed it?

[ob-ivan]

@Nikratio you guess it right:

[ivan@fedora ~]$ pkg-config --modversion fuse3
Package fuse3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `fuse3.pc'
to the PKG_CONFIG_PATH environment variable
Package 'fuse3', required by 'virtual:world', not found

I used find to (ahem) find fuse3.pc located in ~/Install/fuse-3.2.0/build/meson-private/fuse3.pc path (Install being the directory where I move files before running various installers), which is a bit unexpected.

I would (rather naively) expect installers to place package- or service-related files to corresponding system folders by default, as they do with /etc/init.d/ scripts for example. And if not, then the necessity of moving those around or adding their paths to various environment variables to be documented (either in libfuse, or sshfs, or both). Could it be a documentation issue? Or the reader is the problem?

PS. Also, in my current environment echo $PKG_CONFIG_PATH gives empty string. If I set it to the full path to fuse3.pc, then it gives me Native dependency 'glib-2.0' not found. So my next move would be collecting all package config paths in the variable? I have no clue as how to locate them.

[Nikratio]

Thanks for checking! Meson is normally installing the .pc file in the right path. Apparently it didn't work for you though. I'm closing this issue now since it seems to be a libfuse bug. It would be great if you could re-file it at https://github.com/libfuse/libfuse/issues. Please include the output of ninja -v install. In my case, it includes:

Thanks for the discussion! I'm having the same issue

This problem still exists. Ubuntu 20.04:

git clone https://github.com/libfuse/sshfs.git
cd sshfs
mkdir build
cd build
sudo apt update

# install dependencies
sudo apt install meson cmake fuse3

meson ..

Build errors:

How do I fix this and get it to build?

[ElectricRCAircraftGuy]

It looks like I was missing a few dependencies: libfuse3-dev and libglib2.0-dev. So, do this instead:

# install dependencies
sudo apt install meson cmake fuse3 libfuse3-dev libglib2.0-dev

References:

1. for libglib2.0-dev: https://askubuntu.com/questions/58321/how-do-i-install-glib/58357#58357
2. for libfuse3-dev: https://github.com/sbencoding/wdfs/issues/7#issuecomment-585919576

Here's the full steps. I'll update the readme and do a PR to resolve both this issue and #121.

build:

git clone https://github.com/libfuse/sshfs.git # <==== DON'T DO THIS! DOWNLOAD LATEST TARBALL RELEASE INSTEAD!
cd sshfs
mkdir build
cd build
sudo apt update

# install dependencies
sudo apt install meson cmake fuse3 libfuse3-dev libglib2.0-dev

meson ..

Note: mesonconf doesn't work, so use meson configure instead! See meson -h for help options.

ninja # build and link; this produces the `sshfs` executable output!

This still happens. Above code solved it.
