tmp/util.cpp(16): error: identifier "creal" is undefined

[jeffhammond]

From what I can tell, you are using C99's creal in C++ code. I see this issue observed on Stackoverflow but have not figured out how to solve it yet.

This may be relevant:

TTC-github jrhammon$ icpc -v
icpc version 16.0.2 (gcc version 4.9.0 compatibility)

[jeffhammond]

You might need to use C's _Complex instead of the macro complex, since that confuses C++. Source

[springer13]

I've added a quick bug fix. Please try again. I will look into _Complex vs complex if the problem should still exist.

[jeffhammond]

Change does not help. It happens with both Intel and Clang though, so it could be a Mac-specific issue.

The source that reproduces this is quite simple:

#include <cstdio> // or stdio.h
#include <ccomplex> // or complex.h

void printMatrix2Dcomplex(const double *A, int *size){
   for(int i=0;i < size[0]; ++i){

I posted a question on StackOverflow: http://stackoverflow.com/questions/36747506/identifier-creal-is-undefined-seen-on-mac-but-not-on-linux

[springer13]

are you sure that you installed the updates as well (i.e., "python setup.py install --user")? There should not be any call to creal in the generated code anymore.

The example that you mentioned is compiling on our linux system with icpc 16.0.1

[jeffhammond]

I did not do that. Sorry.

It is a different issue, but python setup.py install --user does not work for me. I have been doing python setup.py build.

[springer13]

this needs to be an issue related to the build/installation process because util.cpp should not have any calls to creal any more (compare https://github.com/HPAC/TTC/blob/master/ttc/transposeGenerator.py line 384). On my system util.cpp indeed does not have any creal calls any more.

I would guess that TTC is including an old version of transposeGenerator.py from some other location.

[jeffhammond]

I'm really confused, because I nuked the entire directory and started over, yet the same issue appeared. This happened twice.

I can only assume TTC is getting something from outside the directory tree. Do you know where?

[jeffhammond]

Ok, I found it. Need to resolve my issues with install.

[springer13]

is it possible that you used "python setup.py install --user" or "python setup.py install" before? In that case TTC will be installed in the directory of your python folder (for me this would be /usr/local/lib/python2.7/site-packages/ttc/). You might have to delte the files there first.

[jeffhammond]

Yeah, that's what happened. I purged the files but I guess I need to install again. Is there any way to install without modifying files outside of my directory tree?
