Looking at your first message, I just realized that you are building using "gcc version 4.3.0 20070531 (experimental)" This is the unstable active development version of GCC. It's highly unlikely to actually work to build Sage. Please switch to using GCC-4.2.1 (or less) instead, and try the entire build from scratch. -- William > > Here is the start of the error messages relating to building > flint-0.2.p3: > > > g++ -fPIC -shared -fPIC -o libflint.so mpn_extras.o Z.o memory- > manager.o Z_mpn.o ZmodF.o ZmodF_mul.o ZmodF_mul-tuning.o fmpz.o > fmpz_poly.o mpz_poly-tuning.o mpz_poly.o ZmodF_poly.o -lgmp > Z.o: In function `__gmpz_fits_uint_p': > Z.c:(.text+0x0): multiple definition of `__gmpz_fits_uint_p' > mpn_extras.o:mpn_extras.c:(.text+0x0): first defined here > ... > > Here is the end: > > ZmodF_poly.o: In function `__gmpz_neg': > ZmodF_poly.c:(.text+0x5a40): multiple definition of `__gmpz_neg' > mpn_extras.o:mpn_extras.c:(.text+0x19d0): first defined here > ZmodF_poly.o: In function `__gmpz_abs': > ZmodF_poly.c:(.text+0x5a60): multiple definition of `__gmpz_abs' > mpn_extras.o:mpn_extras.c:(.text+0x19f0): first defined here > collect2: ld returned 1 exit status > make[2]: *** [libflint.so] Error 1 > make[2]: Leaving directory `/local/sage-2.8.5.1/spkg/build/ > flint-0.2.p3/src' > Error building flint shared library. > > real 0m13.440s > user 0m13.025s > sys 0m0.288s > sage: An error occurred while installing flint-0.2.p3 > Please email sage-devel http://groups.google.com/group/sage-devel > > > > Elizabeth > > On Sep 28, 10:43 am, "William Stein" <[EMAIL PROTECTED]> wrote: > > Hello, > > > > I've posted a new spkg for flint here: > > > > http://sagemath.org/packages/standard/flint-0.2.p3.spkg > > > > which takes into account all Bill's > > remarks below.
