Where “myserver” is the hostname of the box. (Which is in /etc/hosts as an alias, but my BIND only knows myserver.mydomain.org, so … I managed to get it to work once. But I forgot what exactly made it work. :(
Oh, of course this is 3.1.0 here.
Created attachment 291445 [details] strace -o strace.log -f -ttT -s 1024 /usr/bin/mlnet # On my system Added my strace. By the way, I remember that I did a gdb backtrace the last time before it worked, and got only question marks. so I recompiled glibc and mldonkey in debug mode (as described in the guide how to get useful backtraces in Gentoo). And I think that is when it started to work. I went back to normal afterwards. I will go to debug again, and see if it works again. If yes, we’d have a very useful reproducible working / not working example comparison.
OK, it works again. With the following: #ACCEPT_KEYWORDS="x86" CHOST="i686-pc-linux-gnu" # pentium4-pc-linux-gnu gibt es nicht als „hardened“. #CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer -pipe -fno-ident -fweb" # normal #CFLAGS="-O1 -march=pentium4 -pipe -ggdb" # debug CXXFLAGS="${CFLAGS}" LDFLAGS="-Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed" MAKEOPTS="-j3 -s" EXTRA_ECONF="-q" And this added: FEATURES="${FEATURES} nostrip" # debug When I uncomment the “normal” line, comment the “debug” lines out, recompile glibc and mldonkey, and restart mldonkey, it hangs again.
I found the key problem: It’s the -fweb. With everything in make.conf normal, and just removing the -fweb, it worked. But I want to keep that. Luckily there is another way: > echo 'CFLAGS="${CFLAGS} -fno-web"' > /etc/portage/env/no-fweb.conf > echo 'CXXFLAGS="$CFLAGS" # So this file can be used generically.' >> /etc/portage/env/no-fweb.conf > echo 'net-p2p/mldonkey no-fweb.conf' >> /etc/portage/package.env So the bug title should be changed to: > net-p2p/mldonkey needs -fno-web or it will hang on start. And the -fno-web should be built right into the ebuild. Maybe it should even be added to the OCAML eclass. Problem solved. :) Now I need you, Chaos and the Gentoo net-p2p team.
@Chaos: Btw: -funroll-loops implies -fweb, says the gcc man page. That’s why it happened to you.
Totally confirmed, thnx Nadi :-)
You’re welcome, but who’s “Nadi”? ;)
The monster that eats letters ;-)
