Subject: [dpdk-dev] Build errors due to duplicate version.map entries in librte_power
Date: Mon, 15 Feb 2021 14:18:24 -0500 [thread overview]
Message-ID: <f7ta6s59m2n.fsf@dhcp-25.97.bos.redhat.com> (raw)
Greetings,
During CI runs, I've noticed lots of failures from the Travis-CI side
all related to librte_power/version.map containing some duplicate
symbols. It seems commit 4d3892dcd77b ("power: make channel message
functions public") made the following hunk:
diff --git a/lib/librte_power/version.map b/lib/librte_power/version.map
index 69ca9af616..13f0af3b2d 100644
--- a/lib/librte_power/version.map
+++ b/lib/librte_power/version.map
@@ -34,4 +34,8 @@ EXPERIMENTAL {
rte_power_guest_channel_receive_msg;
rte_power_poll_stat_fetch;
rte_power_poll_stat_update;
+
+ # added in 21.02
+ rte_power_guest_channel_receive_msg;
+ rte_power_guest_channel_send_msg;
};
As can be seen, rte_power_guest_channel_receive_msg was added already
(it's present in the hunk itself). The rte_power_guest_channel_send_msg
function was added as part of 85ff364f3bd3 ("build: align symbols with
global ABI version").
I guess it may not be allowed to have duplicate symbols here, because in
travis, I see (only for some builds):

Thoughts?
