Just to truck our email conversation I'll copy paste my findings so far: I've actually checked and neither: - the libcurl.so I have on cc7, - nor the libcurl.so I have on fedora 28 - nor the libcurl.so I have on ubuntu xenial have .gnu.version_d. I also tried building curl from sources (7.53.1, as advised) and then build xrootd against it, and it works just fine for me. Cannot reproduce the problem. Looking a: https://serverfault.com/questions/696631/libcurl-so-4-no-version-information-available https://stackoverflow.com/questions/30017397/error-curl-usr-local-lib-libcurl-so-4-no-version-information-available-requ makes me think you might have installed more than one version of libcurl, which might cause the problem. Let me know your thoughts. Cheers, Michal -- You are receiving this because you are subscribed to this thread.
