This was reported ages ago here: https://groups.google.com/d/msg/sage-support/lNp5t-vbT9c/yTHo9Bl1vdAJ but I also encountered this problem recently on some machine I'm not admin of. Fortunately, there was another more recent version of makeinfo later in PATH and I could modify PATH so that it was picked first. Don't feel obliged to do anything about that as the right solution is to update makeinfo, but it may be quite difficult sometimes without admin rights or whatever. For example if some other binaries are in the same directory as the old makeinfo and you don't have any right on this dir (ok, then you could compile your own makeinfo and put it in PATH first, or just modify MPFR yourself...). Best, JP </pre> flori-jpENlDPnyY8< at >public.gmane.org 2013-03-29T18:02:21 http://comments.gmane.org/gmane.comp.lib.mpfr.general/1906 <pre>NARS2000 is an Experimental APL Interpreter released under GPLv3 that has datatypes for multi-precision floating point numbers (via MPFR) as well as multi-precision rational numbers (via MPIR).

I am trying to compile gcc with mpfr in-tree, and I am configuring mpfr with --enable-decimal-float. When invoking 'make', make is trying to configure the mpfr tree, and then breaks with "configure: error: decimal float support requires --with-gmp-build". So I re-configure gcc with --with-gmp-build (although it is in-tree as well), and it then breaks with "configure: error: Do not use --with-gmp-build and other --with-gmp options simultaneously" Checking the mpfr config.log, it says that it added --with-gmp-include and --with-gmp-lib automatically. I am not sure whether this is a gcc issue, or an mpfr issue. However, this prevents me from building gcc with decimal float support at the moment. Is there a way around it? Or am I missing out something?
