Error: 'curl_parse_url' is not an exported object from 'namespace:curl' - curl version

[temospena]

Hi all,

This is just a heads up about an error.

I was using osmdata with a previous curl version on my pc (5.2.3 - not 100% sure about last digit), and any operation such as opq() or simply set_overpass_url() would throw the error:

> osmdata::set_overpass_url("https://maps.mail.ru/osm/tools/overpass/api/interpreter")
Error: 'curl_parse_url' is not an exported object from 'namespace:curl'

updating curl to version 6.0.1 seems to solve that.

Maybe useful to make it explicit here:

osmdata/DESCRIPTION

Line 34 in bd4fd9c

curl,

But honestly I didn't make other experiments, sorry.

Thanks

It was introduced in 6.0, but it's quite recent. I don't remember recent changes in this front in osmdata nor direct calls to curl_parse_url.

Seems that httr2::parse_url() started to use curl_parse_url in v1.1.0. I would depend on this.

[jmaspons]

@temospena did you have dev builds of curl or httr2 packages? Or perhaps updated httr2 without the stated dependencies? I don't know how the upgrade manage dependencies...

[temospena]

Humm, not sure if I understood you correctly, so sorry for my response.

I usually use the non-dev tools, and, since ~september 2024, I am managing and updating r packages with https://eddelbuettel.github.io/r2u/ system in ubuntu 24.
Apparently, curl was not updated with this system, but I checked and I am using httr2 1.1.0 (automatically).

[jmaspons]

Yes, my guess is that using httr2 1.1 will pull curl 6.1 as a dependence, but it seems that was not the case for you. Let see if @mpadge have any idea

Thanks for asking @temospena, but that is definitely a case of mis-matched system libraries, and not anything related to this package. @jmaspons Note that I am going to close your suggested fix in #352, because that would prevent this package being able to be used with older versions of both system libraries and R packages. As things are, this package has almost no requirements for recent software, and will work fine on systems which have not been updated for several years. Problems will only arise if {httr2} is updated to integrated r-lib/httr2#582 without updating the system curl library.

The actual system dependency arises in the curl package, which requires libcurl >= 7.62. That was released in 2018, so it's not surprising that attempting to use any R-curl functionality with a system library now 7 years out of date might cause issues.

@jmaspons if you're in agreement, my suggestion would be to simply close this as unrelated to this package. Okay with you? And thanks for the heads-up anyway @temospena, it's always useful to get insights like this regardless 😄

[jmaspons]

Thanks, @mpadge. I didn't understand the problem with the dependences but I think you are right.
