Unable to build on ArchLinux / Failed requirements

[corbin-c]

Hi there,

I'm trying to build CuraEngine from source on my machine.

The build process with conan seems kinda broken.

As per the wiki, I've installed conan in version 1.65.0. I'm running this in a venv so it doesn't mess with my whole setup:

$ python -m venv cura_venv
$ source cura_venv/bin/activate
$ pip install conan==1.65

Now I can assert conan is running fine:

$ conan --version
Conan version 1.65.0

The profile setup runs fine. But then, when trying to install, I get the following:

$ conan install . --build=missing --update
WARN: **************************************************
WARN: *** Conan 1 is legacy and on a deprecation path **
WARN: *********** Please upgrade to Conan 2 ************
WARN: **************************************************
ERROR: Error reading '/home/user/.conan/profiles/cura.jinja' profile: ConfigParser: Unrecognized field 'replace_requires'

As far as my understanding of conan goes, replace_requires is a conan >2 option. This seems in contradiction with the specified version (1.65.0). This is weird, but I found a workaround by removing the section altogether in the cura profile.

Anyway, let's try and re-build!

$conan install . --build=missing --update

scripta/0.1.0@ultimaker/testing: Not found in local cache, looking in remotes...
scripta/0.1.0@ultimaker/testing: Trying with 'conancenter'...

ERROR: Unable to find 'scripta/0.1.0@ultimaker/testing' in remotes

As you can see, the build process stops because of the missing dependency scripta/0.1.0@ultimaker/testing.

I have tried a few things, in particular removing the cura remote with conan remote remove cura or manually adding a remote: conan remote add cura-conan https://cura.jfrog.io/artifactory/api/conan/cura-conan, all without success.

Any help is very welcome!

For anyone facing the same issue, I found a workaround. One has to use the old conan config (pre v.2). So, instead of doing this step from the wiki:

conan config install https://github.com/ultimaker/conan-config.git

Do the following:

git clone https://github.com/ultimaker/conan-config.git
cd conan-config
git checkout 3226488623c642b40ca7ce3f62d3f33de046d11e
cd ..
conan config install ./conan-config

Once this is done, I had to alter the remotes too, by adding conan center and removing cura private, so that ~/.conan/remotes.json looks like this:

{
 "remotes": [
  {
   "name": "conancenter",
   "url": "https://center.conan.io",
   "verify_ssl": true
  },
  {
   "name": "cura",
   "url": "https://cura.jfrog.io/artifactory/api/conan/cura-conan-dev",
   "verify_ssl": true
  }
 ]
}

I hope this helps someone, somewhere!

I have solved as well, thank you.
