Beyond what Thomas said - LFS-7.0 was released in late 2011. At that time there was no corresponding BLFS release. That version of LFS contained glibc-2.14.1 and linux-3.1 : both are now very out of date, with many known vulnerabilities. I cannot begin to guess what instructions you are following, nor which version of libpng (if before the 1.6 series, later versions of earlier series are available from http://www.libpng.org/pub/png/libpng.html ) With *current* libpng (1.6.34 - not yet in the book when I last looked) configure gives me checking for working strtod... yes checking for memset... yes checking for pow... no checking for pow in -lm... yes checking for clock_gettime... yes checking for zlibVersion in -lz... yes So the pow() function should be found in libm on gnu-linux. This suggests that not only is your system very old, there might be something else different about it (different platform, different libc). Also, any build problems after LFS has been booted belong on the blfs-support list: but you'll need to give those of us subscribed to that list a *lot* more information about the problem if you want any answers : which instructions you followed for MPlayer and libpng, possibly the exact error details (maybe config.log might have something more on this, since apparently the omission caused configure to stop), and what is different about your system. Since you are using 7.0, I guess this might be a 32-bit system ? The i686 architecture should have worked for all of the last 6 years, but lesser variants (i586, i486, i386) maybe are no longer supported and products not from Intel or AMD (e.g. cyrus, soekris, via) might have differences. The first few lines of /proc/cpuinfo will tell you the vendor_id and model name. ĸen -- Truth, in front of her huge walk-in wardrobe, selected black leather boots with stiletto heels for such a barefaced truth. - Unseen Academicals -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
