Unable to compile INTERVAL

[funchal]

/usr/bin/ld: INTERVAL/chcw.o: relocation R_X86_64_32S against `.bss' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Nonrepresentable section on output

I have tried adding -fPIC to the makefile without success. Also tried crosscompiling to 32 bit (using gcc -m32) which didn't work.

Which operating system do you use?

Thanks for the quick reply. I have pasted my OS info below.

BTW, I have also tried the "demo" link (https://www.aptlab.net/p/FPTaylor/FPTaylorVM) too and that didn't work either, but then I was able to find this other page (https://sites.google.com/site/fptaylordemo/installation) with a VM image that works for me.

Distributor ID:	Ubuntu
Description:	Ubuntu 16.10

I don't know how to fix the INTERVAL library issue. I tried several things in Ubuntu 16.10 without success. You may try Ubuntu 16.04 where everything should work.

I'm going to remove the link to the AptLab demo because it is not the first time when it does not work.

In future, I plan to remove the INTERVAL library from FPTaylor and replace it with a better supported interval arithmetic library (if I find a good candidate).

[funchal]

Oh well, thanks for trying. Having the link to the VM file (https://sites.google.com/site/fptaylordemo/installation) would be a great instead of AptLab. Thanks again for looking into it.

FPTaylor can be compiled on Ubuntu 16.10 now with the command make fptaylor-simple-interval. Trigonometric functions are not supported yet. See the last comment in #2.
