I installed an Ubuntu Karmic virtual machine to see how Sage compiles there...and right now, it doesn't.
I've tried on a 64-bit and 32-bit VM, with between 768 and about 1250 MB of RAM allocated to the VM, and it consistently fails while compiling base3.c from pari (src/basemath/base3.c). When it gets to base3, the compiler gradually uses up more and more memory, until it either gets killed by the kernel OOM stuff, or dies with "gcc: Internal error: Killed (program cc1)". This is with 4.1.2.alpha1, but the same behavior occurred with 4.1.1. In Karmic, the compiler is: $ gcc -v Using built-in specs. Target: i486-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.4.1-3ubuntu3' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4 --program-suffix=-4.4 --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-mpfr --enable-objc-gc --enable-targets=all --disable-werror --with-arch-32=i486 --with-tune=generic --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu Thread model: posix gcc version 4.4.1 (Ubuntu 4.4.1-3ubuntu3) On a current Ubuntu Hardy system (like sage.math, but a 32-bit VM with 768 MB RAM) the compiler goes through base3.c with no trouble. Can anyone else confirm (or perhaps even fix) this? Dan -- --- Dan Drake ----- http://mathsci.kaist.ac.kr/~drake -------
