I'm trying to install v3.1.2 of flint into my account on the MPCDF HPC cluster.
I managed to install GMP 6.3.0, MPFR 4.2.1 in my home directory with ./configure --prefix=$HOME/software/<packagename> for the two packages.
From the flint directory,I followed the online docs and manage to get till the ./configure step using:
>>> cd flint/
>>> ./bootstrap.sh
>>> ./configure --prefix=$HOME/software/flint/ --with-gmp-include=$HOME/software/gmp-6.3.0/include/ --with-gmp-lib=$HOME/software/gmp-6.3.0/lib/ --with-mpfr-include=$HOME/software/mpfr-4.2.1/include/ --with-mpfr-lib=$HOME/software/mpfr-4.2.1/lib/
However, when I move to the make step, I get this output:
/usr/bin/mkdir -p build/generic_files
CC generic_files/inlines.c
CC generic_files/profiler.c
CC generic_files/sprintf.c
CC generic_files/fscanf.c

Can someone help me figure out where the problem is?
Your compiler is complaining about C's _Thread_local keyword. This was new in C11, now 13 years old and obsoleted by C17, which itself is soon to give way to a new revision of the language. The format of the diagnostics and the fact that you tagged Linux suggest that you are using GCC to compile this code, but if so then it must be a fairly old version that defaults to C99.
However, as long as your GCC is not absurdly old, you should be able to instruct it to compile in C11 mode by adding the option -std=gnu11 to your CFLAGS. I would recommend doing that at configure time ...
CFLAGS='-std=gnu11' ./configure [...]
... but if you don't wnat to re-configure then you can probably add the flag when you run make, instead:
make CFLAGS='-std=gnu11'
