#19 v1.7.3 linux - compile error

[Ondřej Ticháček]

Hi again,
I'm compiling the daetools project itself, however I again get an error.
Ubuntu 16.04, system python 3.5, gcc 5.4.0.

I would try with the newer gcc, however, I don't know how to set it. The usual

export CC=/usr/bin/gcc-7
export CXX=/usr/bin/g++-7

does not seem to work

$ sh compile.sh --with-python-version 3.5 all

Yes, I noticed that too. It is not a compiler issue. cend is available only in c++11 and a couple of projects miss the -std=c++11 flag since they do not use any other features from it.
I already fixed it and planned to commit with the new release. I could do it now so you can proceed.

[ciroki]

I committed a new version with the fixes. Please try and let me know if t works.

[Ondřej Ticháček]

Hi, I updated the repo, recompiled all libraries and now nodes_compute_stack.cpp compiled fine.
However, I encountered other errors - possibly due to missing -std=c++11 flags when compiling some libraries.

Right, that is the reason. It seems that new gcc versions have the features from the std library available in c++11 switched on by default.
You can fix it yourself, just add to trunk/dae.pri file (somewhere around line 200 where the other compiler flags are specified):

QMAKE_CXXFLAGS += -std=c++11
QMAKE_LFLAGS += -std=c++11

Thank you, it worked! (I couldn't reply sooner, the sourceforge site was down)
