Hi Yuri,
But the pkg-config file is likely not really read by libtool.
I think it may be reading a libevent.la or libcrypto.la file or
something like that and pick up something like "
inherited_linker_flags=' -pthread' " this.
If there is some .la file in /usr/local/lib or /usr/lib, and it contains
-pthreads, likely for the gcc linker, you should (temporarily) move that
out of the system dir. So that libtool does not pick up the gcc
oriented options.
Looks like the devtools work with most gcc options but '-pthreads' looks
like, it could be, possibly, the cause of the problem. Because it
complains about '-h' and that is a '-h' that gets weirdly inserted by an
inherited linker flag. And libtool adds it to the commandline.
So if that libevent installed a .la file in the system dirs, that file
is likely the issue. On my system by the way, Linux, there is no .la
files in /usr/lib. But I guess if there was one by mistake libtool
would pick up the flags from it. And if it then contains the
-pthreads. But I do not know for sure. Otherwise, we'd be back to
trying to figure out why ./libtool includes extra options on the linker
commandline that make it fail...
If all that fails you could copy and paste the linker line, /bin/cc ...
without that -pthreads option and see if that works.
Best regards, Wouter
