flint 2.9.0 fmpz_gcd_ui problem

[doug7...@gmail.com]

I used a standard  ./ config with no args.

During the make run the line 

  CC   ../build/fmpz/fmpz_gcd_ui.o

printed.

A find command yielded

 ./build/fmpz/fmpz_gcd_ui.d

./build/fmpz/fmpz_gcd_ui.o

But make check yielded

/home/doug/miniconda3/bin/../lib/gcc/x86_64-conda-linux-gnu/10.4.0/../../../../x86_64-conda-linux-gnu/bin/ld: t-gcd_ui.c:(.text.startup.main+0x22c): undefined reference to `fmpz_gcd_ui'

I am using linux mint 20.3, ryzen 5600 cpu, 32 GB main memory.

gcc -v yields

  gcc version 10.4.0 (conda-forge gcc 10.4.0-16)

Hello Doug7,

I'm not a Flint developper, but I follow this project and I'm not able
to reproduce your problem.

My gcc is 11.3.0-5.Of course there are some warnings but I wonder if
you have tested other versions of GCC, as usual. That could be yielded
via a lot of things but may I suggest trying other versions of GCC?

I could be wrong of course.

All the best,

Greg
PS / Kali Linux on WSL 2 (no matter, I don't mind)

I tried another version of gcc and could not reproduce the problem.  Consider the problem closed.

Thanks for the report. Always good to know.
It's usual with GCC; My admiration for the gcc developers.
I know some (g++)

I think this is unlikely to be either a gcc or flint issue, but some
kind of linking issue on the machine in question.

Ordinarily flint supplies all the info needed to the linker when
running make check. But perhaps something is interfering with this, I
don't know.

The only thing I can recommend is checking that the directories that
are inserted at the beginning of the flint Makefile by configure are
correct (if not supply them to flint using the --with-gmp, --with-mpfr
options, etc.), and if so, try specifying LD_LIBRARY_PATH manually
before running make check.

Bill.

It was good apparently with good parameters. Good
