[question] Source Code Mirror of manually built dependency down #7967

Closed simue closed 1 month ago

simue commented 2 years ago

I am building dependencies for the md5 examples myself, since they are not in conancenter in the needed configuration. When conan tries to get the sources for pcre, it fails with a handshake time out. Upon inspection it is obvious, that the ftp server from pcre project is down. https://downforeveryoneorjustme.com/ftp.pcre.org

What should I do in such a case? Do I have to wait for pcre to patch their recipes, or can I redirect the source mirror url myself?

Hi @simue

The quick fix would be something like (orientative, not tested):

I am moving this to conan-center-index repo, in case someone wants to provides a mirror in the official recipe

memsharded commented 2 years ago

This is a blocking "bug"= not working, but the cause is external to Conan. Maybe the recipe could provide a mirror if there is one. Maybe pcre server is restored quickly

fixed in https://github.com/conan-io/conan-center-index/pull/7956. Clear pcre from your conan cache and install again.

Thank you both, I will be able to test this on Monday.

I see that in adc2bc6a637012a7cfa826db1e8c014d7ceb5627 the sha hashes were changed. How would I create them for updated mirros? is this automatically done by conan? Further more I tested memsharded's workaround and it fails when pcre's test_package is built. It can't find the header - do I need to provide the location of the header file and how would I do this?

Since the lib itself was built successfully I got a working pcre package anyways. Clearing pcre from cache and installing again works, too.

Hi there, I was reviewing old issues and I have come across this one.

How would I create them for updated mirros? is this automatically done by conan?

The recommended way to calculate the sha256 is described in here https://github.com/conan-io/conan-center-index/blob/master/docs/adding_packages/conandata_yml_format.md#sha256

Anyways, I'm closing this issue as pcre recipe has suffer plenty of modifications since this issue was open. Between them, we do not have anymore multiple remotes for each version.

Happy coding 🐸
