I tried to build sage-3.2.2 using gcc/g++ 4.3.2 on an Archlinux 2.6.27 x86_64.
The build fails then it tries to link libpari.a, which had not been compiled with the -fPIC flag. The relevant part of the rror message: g++ -fPIC --shared libjcntl.a interface_n.o arith_n.o marith_n.o gpslave_n.o conic_n.o legendre_n.o unimod_n.o quadratic_n.o cubic_n.o illl_n.o hilbert_n.o parifact_n.o p2points_n.o compproc_n.o kbessel_n.o vector_n.o matrix_n.o subspace_n.o mvector_n.o mmatrix_n.o msubspace_n.o xsplit2_n.o timer_n.o svector_n.o smatrix_n.o smatrix_elim_n.o polys_n.o realroots_n.o gf_n.o -o libjcntl.so -L/ home/katana/builds/sage-3.2.2/local/lib -lntl -lgmp -lpari -lpari -L/ home/katana/builds/sage-3.2.2/local/lib -L/home/katana/builds/ sage-3.2.2/local/lib -lntl -lgmp -lpari - lm /usr/bin/ld: /home/katana/builds/sage-3.2.2/local/lib/libpari.a (arith1.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with - fPIC /home/katana/builds/sage-3.2.2/local/lib/libpari.a: could not read symbols: Badvalue collect2: ld returned 1 exit status make[3]: *** [libjcntl.so] Error 1 make[3]: Leaving directory `/home/katana/builds/sage-3.2.2/spkg/build/ eclib-20080310.p7/src/procs' make[2]: *** [so] Error 2 make[2]: Leaving directory `/home/katana/builds/sage-3.2.2/spkg/build/ eclib-20080310.p7/src' Error building cremona shared libraries real 3m1.115s user 2m17.618s sys 0m6.906s sage: An error occurred while installing eclib-20080310.p7 Please email sage-devel http://groups.google.com/group/sage-devel explaining the problem and send the relevant part of of /home/katana/builds/sage-3.2.2/install.log. Describe your computer, operating system, etc. If you want to try to fix the problem, yourself *don't* just cd to /home/katana/builds/sage-3.2.2/spkg/build/eclib-20080310.p7 and type 'make'. Instead type "/home/katana/builds/sage-3.2.2/sage -sh" in order to set all environment variables correctly, then cd to /home/katana/builds/sage-3.2.2/spkg/build/eclib-20080310.p7 (When you are done debugging, you can type "exit" to leave the subshell.) make[1]: *** [installed/eclib-20080310.p7] Error 1 make[1]: Leaving directory `/home/katana/builds/sage-3.2.2/spkg' This error had been reported in Jan 2008, but the person who reported the issue never followed up... Should I clean everything and rebuilt after setting CFLAGS and CXXFLAGS = -fPIC? Most libraries that have been built all seem to have been built using the -fPIC flag. Is it safe to set this flag globally? Another issue that I've been having is that I would like to build each package separately. (So I wouldn't have to rebuild the whole thing when an error like this occurs...) Is there a way of doing this? I wanted to use Intel compilers, but they seemed to fail with some of the packages (e.g. gmp-fake*, NTL, perhaps more?), so I would like compile whatever I can with Intel, and compile the rest with GNU compilers.
