error compiling package giac-1.4.9.45

[David Coudert]

I have a compilation error with package giac-1.4.9.45 during the compilation of SageMath version 8.2.beta4 on a linux computer (make build -j1).

See attached log file.

Any help is more than welcome.

David.

[David....@inria.fr]

what is the smart way to do that (i.e., without make dist-clean) ?

[François Bissey]

./sage -f gcc
it will rebuild mpir/mpfr/mpc after gcc but that’s ok.

[David Coudert]

Thanks. I have recompiled gcc.

However, the compilation of giac is still failing :( 

See attached log.

Different problem. There seem to be an issue with libpng.

OK after checks, it means it tries to link with libpng-1.2 rather than
a newer one like we have in sage now (1.6). Can you send the config.log
from giac?

I don’t know where to find this file.

/home/dcoudert/sage/local/var/tmp/sage/build/giac-1.4.9.45/src/config.log
if I am not mistaken.

[David Coudert]

right. Here it is.

Thanks.

What version of libpng is installed? Can you post the output of
ls -la /home/dcoudert/sage/local/lib/libpng*

No `libpng.so`? If not, that’s the problem, sage’s install of libpng
is broken or giac should be made to find libpng16.so first.
Let’s try re-installing libpng first:
./sage -f libpng

François

[David Coudert]

Working !!!

I reinstalled libpng (./sage -f libpng), so now I have libpng.so and libpng.a

Then `make build -j1`. It recompiles many stuff but it went to the end.

Thank you very much for your help.

David.
