[Hk-classes-discuss] Suggest about compilation

[TomasiL <arc...@to...>]

i hope these information about hk_classes installation are useful for 
someone

An update version of hk_classes at this address:

https://sourceforge.net/projects/knoda4/files/hk_classes/

useful for knoda4 and knoda5

Compiling hk_classes on Debian9 64 this error occurred:

Patrik Hanak (knoda4 e knoda5 developer) help me and i solved so:

"I have got an experience with similar errors. They occured, when C++ 
compiler followed C++11 standard. Problem is that hk_classes library is 
NOT C++11 compliant. Solutions would be:
1.  change configuration of C++ compiler to follow older standard, I 
think C++98 would be OK
2. refactor hk_classes sources to follow C++11 standard.

I guess option 1 is faster for the moment."

"I cannot help you without knowing details of Your installation 
(operating system, distribution (if Linux based OS), C++ compiler, 
version of C++ compiler).
At the moment I can provide you with the comfiguration on my side:
I use various Linux based distributions ( OpenSUSE 64-bit, Debian 
32-bit) with GNU C++ compiler. Specific argument to configure script:
 > ./configure CXXFLAGS='-std=c++03 -O2'
solved the issue."

Thank you very much to Patrik Hanak

configure: error:
   Could not link test program to Python. Maybe the main Python library 
has been
   installed in some non-standard library path. If so, pass it to configure,
   via the LDFLAGS environment variable,
   or use the --with-python-incdir and --with-python-libdir directices 
respectively.

    You probably have to install the development version of the Python

them.

i solved installing  libfontconfig1-dev

i hope these usefuls for someone

In italiano:

il link sopra porta a una versione aggiornata delle hk_classes utile per 
installare le versioni più

recenti di knoda: knoda4 e knoda5

Le versioni aggiornate di g++ non riescono a compilare le hk_classes 
ecco perché vanno aggiunti

gli argomenti indicati al comando ./configure.

Il secondo suggerimento indica un pacchetto che non sempre le 
installazioni di base del sistema

includono.

Knoda è un ottimo sistema per la gestione ed amministrazione dei database.

L'unica vera alternativa ad Access in campo Linux.
