cmake error

[Roy Lemmon]

Hi,

I have a problem with the cmake build package.

Below is a small CMakeLists.txt test file where I attempt to download the
file fastjet-3.3.3.tar.gz.

**********************************************************************************
# Specify the minimum version for CMake
cmake_minimum_required(VERSION 3.13.5)

# Project's name

project(hello)

file(DOWNLOAD "http://fastjet.fr/repo/fastjet-3.3.3.tar.gz" "fastjet-3.3.3.tar.gz"  TIMEOUT 60)
**********************************************************************************

When I run this file I get an error about the certificates:

**********************************************************************

CMake Error at CMakeLists.txt:8 (file):

-- Configuring incomplete, errors occurred!
See also "/home/rlemmon/example/CMakeFiles/CMakeOutput.log".
**********************************************************************

Can someone help ?

Thanks
Roy

Do you have the nss-certs package installed? The Guix manual mentions¹ that 
it may need to be, in order for apps installed by Guix to authenticate 
certificates.

If you already have that package, then it's necessary to look at 
CMakeOutput.log to see if there are more hints.

Thanks,
Thiago

Hi Thiago,

Below is CMakeOutput.log

I see no occurence of fastjet though. I should mention that I get no
error if I just use curl or wget to download the file (and it has a
proper size) plus it can then be extracted. Here the download seems to
be interrupted or not started as the file has zero size, though it is
present after running cmake ...

In fact this is part of a larger code base but I have narrowed it down
to this trivial download problem.

Yes I have the nss-certs package installed though I thought that was
just for https sites ?

Thanks
Roy

Is this problem happening during the build of a guix package? If so, as far 
as I know there's no network access inside the build container. This is to 
ensure that the build only uses the inputs described in the package 
definition and thus is reproducible.

That's true. I hadn't noticed that the URL was http and not https. I don't 
know why CMake would need to access CA certificates. One idea would be to 
use the LOG option in the file command to try to get more details (in case 
the build isn't happening inside a guix container as I mentioned above).

Thanks,
Thiago

Re: cmake error

[Roy Lemmon]

Hi Thiago,

In fact it is happening when I make a  high energy physics python package (matplo/heppy on GitHub). I narrowed down the issue to the inability to download the file and so wrote the CMakeFile.txt that I sent you to isolate that issue. In fact I had the idea you mentioned of the LOG file. However when I put that command it, it didn't seem to work.

How do you specify a LOG file with the FILE command ?

Note that all the compilation works if I do it in a Docker container on my Guix laptop (with Debian base).

Thanks
Roy

Re: cmake error

[Roy Lemmon]

Hi again,

Just to not that the original CMakeList.txt file for fastjet uses ExternalProject_Add with the URL command. Perhaps no-one has used cmake in Guix with that option before ... 

Still no solution ...

Cheers
Roy

That's a good possibility. I tried your CMakeLists.txt example with cmake 
installed via Guix and I saw the same error. With my host distro's cmake it 
works fine.

So it appears that file(DOWNLOAD) is broken in Guix's cmake. Perhaps no one 
noticed because when building guix packages, dependencies are download in 
advance rather than as part of the build.

> Still no solution ...

Sorry, I'm not of much help. I only have very limited experience with 
cmake.

I tried using the LOG option in this way:

file(DOWNLOAD "http://fastjet.fr/repo/fastjet-3.3.3.tar.gz"
     "fastjet-3.3.3.tar.gz" TIMEOUT 60 LOG FILE_LOG)
message(STATUS "file log = ${FILE_LOG}")


But ${FILE_LOG} is empty. Not sure whether I'm using the option in the 
wrong way, or file didn't log this problem.

Hi Thiago,

Thanks very much for your help. At least you have confirmed my take on guix's cmake !

Perhaps someone else will come along with some insight. The cmake patch makers for instance ...

I'll keep trying with the log file ...

Cheers
Roy
