Hello World! I've been following an interesting thread here: http://www.linuxquestions.org/questions/linux-from-scratch-13/segfault-in-ld-2-14-so-running-alsa-utils-893812/ about alsa-utils' aplay and speaker-test segfaulting with glibc-2.14. It looks like a bug in glibc so I wondered if it was fixed in current glibc git head. So I've just tried to build with current glibc and configure fails during the first pass in chapter 5 like this:
checking for .protected and .hidden assembler directive... yes checking whether __attribute__((visibility())) is supported... yes checking for broken __attribute__((visibility()))... no checking for broken __attribute__((alias()))... no checking whether to put _rtld_local into .sdata section... no checking for .preinit_array/.init_array/.fini_array support... yes checking whether to use .ctors/.dtors header and trailer... configure: error: missing __attribute__ ((constructor)) support?? lfs:/mnt/lfs/sources$ It looks like current glibc doesn't like the gcc we compile during the first pass in chapter 5. I can configure and build glibc with the gcc on my current system so I suspect that this is because the gcc we compile during the first pass in chapter 5 is a cross compiler and does not have this __attribute__ ((constructor)). Does anyone know any more about this or how to work around it?
