sage 10.7.beta8 with givaro and fflas_ffpack SPKGs traceback issue

[Bagas Sanjaya]

Hi,

I'm building sage 10.7.beta8 on my conda (miniconda3) environment (Arch
Linux host). The env file (`env.yml`) for this purpose is:

```

```

I create the environment and then set up compilation variables:

```
$ conda env create -f env.yml
$ conda activate sagemath
$ export CFLAGS='-march=haswell -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -isystem /home/bagas/miniconda3/envs/sagemath/include'
$ export CXXFLAGS='-fvisibility-inlines-hidden -fmessage-length=0 -march=haswell -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -isystem /home/bagas/miniconda3/envs/sagemath/include'
$ export FCFLAGS='-march=haswell -mtune=haswell -ftree-vectorize -fPIC -fstack-protector-strong -fno-plt -O2 -ffunction-sections -isystem /home/bagas/miniconda3/envs/sagemath/include'
$ export SAGE_DEBUG=no
$ export MAKE="make -j2"
$ export GNUPLOT_DRIVER_DIR='/home/bagas/miniconda3/envs/sagemath/libexec/gnuplot/5.4'
```

Then I build sage:

```
$ ./bootstrap
$ ./configure --prefix=$CONDA_PREFIX --with-python=$CONDA_PREFIX/bin/python --disable-meson-check --enable-fricas=yes
$ make
```

The build succeed, but when I smoke test it, sage returns traceback:

```
$ sage

```

It looks like there's problem in givaro and fflas_ffpack SPKGs (as they're
both built as part of sage distribution instead of conda packages).

Am I missing something? Why is it the case? Should I open GitHub issue on
this?

Thanks.

Any reason you're using the legacy install method? You should use meson to install sagemath in conda, see https://doc.sagemath.org/html/en/installation/meson.html

Nope, though. I'm experimenting with meson and instead the build stopped
due to out-of-memory issues (my laptop has 4GB memory and Core i3 Haswell
CPU).

By default meson will try to use all of your CPU cores at once. See if
passing "-j1" or "-j2" to "meson compile" helps. I build sage on a
laptop with 4GB RAM, so it can be done.
