Building problem on Linux about njoy21

[jlconlin]

When you say it gets "stuck", what do you mean? How long is it stuck? Does it make the njoy21 binary?

[ATM-Jahid]

By stuck, I mean my system becomes unresponsive totally.

% sudo make
[ 21%] Built target utility 
[ 78%] Built target njoy 
[ 82%] Built target njoy_c_bindings 
[ 84%] Building CXX object CMakeFiles/njoy21.dir/src/main.cpp.o

After that I have to restart it.

Right after executing make command, everything seems normal but after reaching that 84%, CPU usage skyrockets (I am assuming ram usage does too) and at some point my laptop becomes unresponsive to anything. The result is the same when I run more than one job (make -j 4)at a time.

What is the destination of the njoy21 binary? I have checked /usr/bin/ and /usr/sbin/. There is no njoy21 file there.

@ATM-Jahid If you have a slow machine, or if there isn't much memory, this could cause some problems. NJOY21 does require a fair amount of memory to compile. It would be easier on the machine if you just did one job (make -j1).

[ATM-Jahid]

Well, I am not sure if memory is the problem. I ran make and make test on the same machine before.

[jlconlin]

make test likely uses less memory than make does.

[ATM-Jahid]

I remember running make that time. It went smoothly. I was running other programs in parallel and I didn't face this sort of problem then.

And, exactly how memory intensive is the process?

[jlconlin]

I don't know exactly off the top of my head. I wouldn't be surprised if it consumed up to 4 GB.

Hey guys! I managed to compile/install the program after solving several issues with permissions and config commands. Yet when I try to run an input I get the following error message:

reconr... 0.0s
At line 212 of file /home/base/NJOY21/subprojects/njoy/src/util.f90 (unit = 20)
Fortran runtime error: Cannot open file 'tape20': No such file or directory

This is not clear so far: should I provide this 'tape20' file or the program was supposed to find it somewhere? When I run the 'make test' command everything is OK, but I cannot run any other input because the code cannot open the tape the input refers to. I checked the NJOY2016 manual but there is no information on such issues. Thanks!!!

@marton384 In short, yes you need to provide your own tape20, this is generally (but not required) to be the evaluated file (i.e., ENDF-formatted file).
