Hello Igor,

This error was fixed in the git, it will be available in the next 1.8 version.

https://git.haproxy.org/?p=haproxy-1.8.git;a=commit;h=fbf09c441a4e72c4a690bc7ef25d3374767fe5c5

However be careful, the spec file provided in the git is an example, it does
not build with the latest features of haproxy.

You should at least build with TARGET=linux2628 for the latest default
features.

Cheers,

Hi Igor,

This is a problem when building haproxy without threads support, that has been
fixed, but only after 1.8.9 was released, so it should be part of the next
release.
In the mean while, you can apply the attached patch, it should do the trick.

Regards,

Olivier

Subject: [PATCH] BUG/BUILD: threads: unbreak build without threads

A few users reported that building without threads was accidently broken
after commit 6b96f72 ("BUG/MEDIUM: pollers: Use a global list for fd
shared between threads.") due to all_threads_mask not being defined.
It's OK to set it to zero as other code parts do when threads are
enabled but only one thread is used.

This needs to be backported to 1.8.

(cherry picked from commit 0cd82e883ef034508ebeef04fd25ffc946e80cfc)
