Description Paulo Andrade 2017-04-25 13:13:05 UTC

Currently on rhel 7.3 this works:
$ perl -e 'use WWW::Curl::Easy; print &CURL_SSLVERSION_TLSv1 . "\n";'

but these fail with an undefined symbol error:
perl -e 'use WWW::Curl::Easy; print &CURL_SSLVERSION_TLSv1_1 . "\n";'
perl -e 'use WWW::Curl::Easy; print &CURL_SSLVERSION_TLSv1_2 . "\n";'

for example:
Undefined subroutine &main::CURL_SSLVERSION_TLSv1_2 called at -e line 1.

  Just rebuilding from sources fetches the symbols from libcurl-devel
and the above examples work. For example:

$ perl -e 'use WWW::Curl::Easy; print &CURL_SSLVERSION_TLSv1_1 . "\n";'

Comment 2 Jitka Plesnikova 2017-04-26 08:36:13 UTC

The bug is solve just by rebuilding perl-WWW-Curl against current RHEL 7  libcurl-devel.

How to test:

1) Install latest perl-WWW-Curl
2) Run commands:

perl -MWWW::Curl::Easy -e 'print &CURL_SSLVERSION_TLSv1 . "\n";'
perl -MWWW::Curl::Easy -e 'print &CURL_SSLVERSION_TLSv1_1 . "\n";'
perl -MWWW::Curl::Easy -e 'print &CURL_SSLVERSION_TLSv1_2 . "\n";'


Before:
1
Undefined subroutine &main::CURL_SSLVERSION_TLSv1_1 called at -e line 1.
Undefined subroutine &main::CURL_SSLVERSION_TLSv1_2 called at -e line 1.

After:
