curl +universal: curl-config differs due to opportunistic use of zstd

[lyssdod (Alex R)]

port -d install curl +ssl+universal fails due to curl-config being different. logs are attached

[lyssdod (Alex R)]

sudo port -d install curl +ssl+universal

This should work. Please try this first:

sudo port clean curl
sudo port -v install curl +universal

and post back the outcome

(as +ssl is the default, I didn't add that to my build line, but feel free as it makes no difference either way)

Agreed, this log was from an unclean build attempt (log contains lines saying Skipping completed) so cleaning and trying again will either install successfully or will generate a log showing what the real problem is; if so, please attach it.

This can be closed now. Upon cleaner inspection of the log, it turned out that i386 curl variant was linked to zstd, and x86_64 wasn't, thus causing curl-config script mismatch (no idea if they were to merge into universal/fat binary later). Reinstalling zstd and bunch of other stuff as +universal has solved the issue. Thank you Ryan!

[kencu (Ken)]

you're welcome.

[ryandesign (Ryan Carsten Schmidt)]

Thanks for the additional info. So the bug is that curl links with zstd but does not declare a dependency on it. If it had declared that dependency, MacPorts would have reinstalled zstd universal for you and you would not have experienced this problem.

curl: Move brotli/http2/idn/psl/zstd to variants

While some users want commonly-used features enabled in curl by default,
others wish to have the option to disable them to build a minimal curl
for MacPorts to link with on older systems. Therefore move brotli,
http2, idn, psl, and zstd features to variants which are on by default.
