With Julian at sage days 130 we noticed other fishy things happening 1) (minor) cmake was not installed in the conda environment
2) (problematic but probably not critical) both system cmake and conda cmake thinks that my blas and cblas are better from the system $ micromamba activate sage-dev (sage-dev) $ cmake --find-package -DNAME=CBLAS -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=LINK /usr/lib/libcblas.so.3.12.0 /usr/lib/libblas.so.3.12.0 On Thu, 29 Jan 2026 at 00:08, Dima Pasechnik <[email protected]> wrote: > > On Wed, Jan 28, 2026 at 4:54 PM Vincent Delecroix > <[email protected]> wrote: > > > > Hello, > > > > In a clone of 10.9.beta4, I created a fresh conda environment > > > > $ micromamba env create --file environment-3.13-linux.yml --name sage-dev > > > > activated it > > > > $ micromamba activate sage-dev > > > > and tried to build sage in it > > > > (sage-dev)$ pip install --no-build-isolation --editable . > > > > but it failed at Cython compilation (see attached file). > > > > Any idea on how to solve it? > > there is an NTL/flint error, did you notice? > Apperently Conda's NTL is non-TLS? > > > /home/vincent/micromamba/envs/sage-dev/bin/../libexec/gcc/x86_64-conda-linux-gnu/14.3.0/ld: > _ZN3NTL8zz_pInfoE: TLS reference in src/sage/ > libs/linbox/linbox_flint_interface.cpython-313-x86_64-linux-gnu.so.p/meson-generated_src_sage_libs_linbox_linbox_flint_interface.pyx.cpp.o > mism > atches non-TLS definition in > /home/vincent/micromamba/envs/sage-dev/lib/libntl.so section .bss > > /home/vincent/micromamba/envs/sage-dev/bin/../libexec/gcc/x86_64-conda-linux-gnu/14.3.0/ld: > /home/vincent/micromamba/envs/sage-dev/lib/li > bntl.so: error adding symbols: bad value > collect2: error: ld returned 1 exit status > > > > > Best > > Vincent > > > > -- > > You received this message because you are subscribed to the Google Groups > > "sage-devel" group. > > To unsubscribe from this group and stop receiving emails from it, send an > > email to [email protected]. > > To view this discussion visit > > https://groups.google.com/d/msgid/sage-devel/CAGEwAAkmeAnmGrzWMjT58-97Ow1kT-8wY_aqKqSV5DGrxkGKWg%40mail.gmail.com. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
