Re: broken dependency_libs handling of -pthread

This leads to link errors on DragonFly, Not only on DragonFly, I would believe. when linking against that library. Typical example is ligthread from glib, which is a dependency of libORBit-2. orbit-name-server-2 is linked against libORBit-2, but without explicit -pthread. This fails with missing symbols. ACK. Attached patch only threats -pthread special and leaves the rest of the flags alone. The problem with the patch is that it breaks backward compatibility. Older libtool versions (1.4.x I believe) require that only libraries and their search paths (i.e., arguments of the form -L.. and -l..) be stored in deplibs. In branch-2-0, we have implemented a scheme which uses a new variable for this and thus solves this problem cleanly. For now, you could just add -pthread to the flags of the depending package (the ACX_PTHREAD macro from the autoconf macro archive would handle this). It sounds bad, but if you think about the fact that usually the depending package has to be careful and know anyway if any of its libraries are threaded, then it does not seem like such a bad assumption any more. At least I believe this is the current situation, I have not looked deeply into this stuff. Please at least comment on this patch, libtool is seriously broken on DragonFly when used with pkgsrc without it. It's good to remind us to look at things. Especially *BSD support within Libtool could be better, and input from the *BSD people would be very helpful to this end. I might add that I have little spare time at the moment, so replies can take a while, sorry.

libtool fails without a CXX compiler installed
(Example is from compiling pkgconfig): Without g++ installed: checking whether we are using the GNU C++ compiler... no checking whether g++ accepts -g... no checking dependency style of g++... none checking how to run the C++ preprocessor... /lib/cpp configure: error: C++ preprocessor /lib/cpp fails sanity check See `config.log' for more details config.log: ... configure:4894: /lib/cpp conftest.cc cpp: conftest.cc: C++ compiler not installed on this system configure:4900: $? = 1 ... Compiles fine with g++ installed. However, when I check the compile log it never calls g++, just checks for its existence and fails out.

Re: libtool fails without a CXX compiler installed
Quoting Bob Friesenhahn [EMAIL PROTECTED]: snip The problems I have heard about up until now have been that autoconf found a C++ compiler, but it was discovered not to work. In this case, autoconf's macro throws up its hands and spontaneously quits. So libtool is not working if there is no C++ at all? Correct. I built my system without g++ installed. Then added xorg, which needs pkgconfig down the dependency line, but that failed. I installed g++ and then pkgconfig would compile fine. After some tests of pkgconfig 0.17.2, 0.16.0, and 0.15.0 I found that the first two fail without g++ installed, but the last, 0.15.0, works fine without g++ installed. I filed a bug[0] with pkgconfig and they told me that libtool is where the failure is occurring even though an older version of pkgconfig worked fine. -sandalle [0] https://bugs.freedesktop.org/show_bug.cgi?id=3376 -- Eric Sandall| Source Mage GNU/Linux Developer eric at sandall.us PGP: 0xA8EFDD61 | http://www.sourcemage.org/ http://eric.sandall.us/ | SysAdmin @ Inst.
