Hi list!
I'm trying to build the Streamer part of the PeerStreamer open source
project (http://peerstreamer.org) using the gcc-mingw-w64 package on
Ubuntu 12.04 (gcc version 4.6.3). The building process goes fine. Some
warnings, but I think that's to expect. When it gets to the final step
of statically linking together all the libraries into a single
executable using the following command, I am met with the following error:
i686-w64-mingw32-g++

collect2: ld returned 1 exit status
Can anyone help me in understanding what this error means?
I made a script that uses nm to look up the _gethostname symbol in all
the involved object files, and this is what it says the various files
contain:
/home/rune/Programming/Streamers-build-win32/Streamers/net_helpers.o
U __imp__gethostname@8
/home/rune/Programming/Streamers-build-win32/THIRDPARTY-LIBS/NAPA-BASELIBS/dclog/libdclog.a
U _gethostname
/home/rune/Programming/Streamers-build-win32/THIRDPARTY-LIBS/NAPA-BASELIBS/3RDPARTY-LIBS/libevent/lib/libevent.a
U __imp__gethostname@8
/usr/i686-w64-mingw32/lib/libwsock32.a
00000000 I __imp__gethostname@8
00000000 T _gethostname@8
/usr/i686-w64-mingw32/lib/libws2_32.a
00000000 I __imp__gethostname@8
00000000 T _gethostname@8
Also, I have all the involved object files in a tgz-archive that I can
attach so you can see if you can reproduce this error itself. But the
archive is 2.3 MB in size, so I'm not sure if it's appropriate to attach
to a mail to this mailing list. Let me know if you want this.
Thanks for your help!
