Hi, I built the software successfully but get the following error:
Start Enc NLGD
division by zero in _ntl_gdiv

It occurs just after the "enc NLGD" message in iteration 5 of the first example in your Readme.
Versions of software are:
NTL 11.4.3 and GMP 6.2.0 - on both Manjaro 5.10.2 and Kubuntu 20.04 (different machines)

If I reduce the polynomial degree from 5 to 3 I get a few iterations further
If I try an example with a larger dataset, I get a few iterations further.
I see that the logq values are decreasing, they get to 168 before the crash.

Do you have any ideas as to an approach to solve this.
Many thanks

hello, i am new here, I meet an issue:
Building file: ../src/CipherGD.cpp

how can i solve this problem? thanks!

I am learning your code,i dont find where did you define logN and logQ.
It's like they suddenly show up.
Can you tell me what they are?Where are they defined?
Thank you very much!

I'm learning your code, but I have some trouble. Please help me!
In your code, I don't know the meaning of some parameters(such as, cnum, slots, sBits, bBits and so on). Where can I get the way to solve the problem? In your paper, I don't find the good way to know these parameters.
some method(such as, encLGD, encMLGD, encNLGD), what is their different point?

Please help me, Thank you so much.

Hello,

When I used make in IDASH2017/run, I got this issue:

Building target: IDASH2017
Invoking: MacOS X C++ Linker
g++ -L/home/ruiqi/Documents/HEAAN-master/HEAAN/Debug -L/usr/local/lib -pthread -o "IDASH2017" ./src/CipherGD.o ./src/GD.o ./src/IDASH2017.o ./src/TestGD.o -lHEAAN -lntl -lgmp
/usr/bin/ld: cannot find -lHEAAN
collect2: error: ld returned 1 exit status
makefile:45: recipe for target 'IDASH2017' failed
make: *** [IDASH2017] Error 1

I've already checked the makefile, so the problem locates at this block:

# Tool invocations
IDASH2017: $(OBJS) $(USER_OBJS)
	@echo 'Building target: $@'
	@echo 'Invoking: MacOS X C++ Linker'
	g++ -L/home/ruiqi/Documents/HEAAN-master/HEAAN/Debug -L/usr/local/lib -pthread -o "IDASH2017" $(OBJS) $(USER_OBJS) $(LIBS)
	@echo 'Finished building target: $@'
	@echo ' '

The HEAAN I installed has no HEAAN/Debug document, it may have caused the problem of make failure. How can I solve this issue?

I had installed the HEAAN library and try to "make" in the /lib, but got into some trouble:
#include <Scheme.h>
^~~~~~~~~~
compilation terminated.
src/subdir.mk:27: recipe for target 'src/CipherGD.o' failed
make: *** [src/CipherGD.o] Error 1

please give me some advice. Thanks!
