LXD 3.18 - build from source issue on Centos 8

LXD

Hello,
I have been trying to build LXD 3.18 from source on Centos 8 and make dep works fine, later make fails.Also, the error below came up after I solved this issue .(by entering _dist/src/github.com/lxc/lxd and then running make)

This is the error I get now:

Please set the following in your environment (possibly ~/.bashrc)

Any help?
(I have the libpcap-devel installed)

I am okay with installing a newer version (in 3.X.X) if such issues are fixed later. I have been following the install from source guide given here.

You need libcap-dev, that may also be called something like libcap2-dev.
libpcap is a network library which is entirely unrelated to this.

Oops! I apologise. I did not realise I made a typo there :slight_smile:
Thanks for your quick help as always @stgraber

@stgraber, Sorry, but I have a follow up:

Can you also please explain what this part does? Is it interpositioning?

I am not able to make this last part work on my machine, so looking for some help.
I guess my GOPATH would still point at _dist?
I think the link describes the case if I install the latest version, not a release. :slight_smile:

If this helps:

$ whereis go
go: /usr/local/go /usr/local/go/bin/go

Do you have ~/go/bin/lxc and ~/go/bin/lxd? If so, then all you really need is the PATH and LD_LIBRARY_PATH to point to the right locations.

Although I have a go/ folder on my $HOME, but that did not have bin. I redirected it to ~/lxd-3.18/_dist because I downloaded a tarball and then installed it from there.

It seems to get the binaries from the right place, hope this is the right way to do it? TIA :slight_smile:

$ which lxc
~/lxd-3.18/_dist/bin/lxc
$ which lxd
~/lxd-3.18/_dist/bin/lxd
