configure: error: Missing Varnish development files.

[RandyCupic]

Hi,

I'm trying to install Varnish modules for Varnish 6.0.6 but ./configure keeps failing with configure: error: Missing Varnish development files..

varnishd -V

I tried tag 0.15.0 and branch 6.0-lts which are supposed to be for Varnish 6.0. My procedure for compiling varnish modules:

cd varnish-modules
git checkout 0.15.0

And then of course make fails with make: *** No targets specified and no makefile found. Stop.

I tried many solutions that I've found online, I tried to reinstall varnish and varnish-dev, but no help. I'm running out of ideas. The weirdest thing is that it worked before, with the same modules tag and same Varnish version, but I had some other issues so I decided to remove and clean everything and then start from scratch. My colleague also managed to install this on his virtual machine (the same Ubuntu 20.04 version as mine) with the same procedure without issues.

What am I missing?

[rezan]

It looks like it cannot find the dev headers. Can you provide the output of these commands:

find / -type f -name vsha256.h 2> /dev/null

dpkg-query -L varnish-dev

grep -A4 vsha256 config.log

Run the last one in the varnish-modules directory.

Well, the problem is that configure is trying to find the headers in /usr/local/include/varnish and not /usr/include/varnish.

Can you provide the contents of: /usr/lib/pkgconfig/varnishapi.pc

[RandyCupic]

Here:

➜  ~ cat /usr/lib/pkgconfig/varnishapi.pc

exec_prefix=${prefix}

sbindir=${exec_prefix}/sbin
libdir=/usr/lib

[rezan]

Well, that looks correct. Did you ever compile and install varnish from source? That could explain the local injection... If so, you would have to remove that installation, ex: make uninstall.

Can I see this command:

find / -type f -name varnishapi.pc 2> /dev/null

[RandyCupic]

@rezan That was it, thank you :) I tried to install Varnish on many ways, including compiling it from source and ended on installing it from repositories (through some adjustments because Ubuntu 20.04 comes with Varnish 6.2 and I needed 6.0 explicitly). The last command that you provided showed me that I had two varnishapi.pc files; one in /usr/lib/pkgconfig and the other one in /usr/local/lib/pkgconfig. Deleting this other one solved the problem.

I actually tried to find all files containing varnish on the filesystem and delete them before but I obviously messed up the regex and somehow overlooked this one.

Thank you so much for your help :) now everything works as it should.

[rezan]

Excellent!
