Обсуждение: pgadmin4: The python-config executable could not be found.

Hi all,
just cloned the git repository and tried to compile it on my ubuntu 15.04 x64:

% qmake
Project MESSAGE: Building for QT4...
Project MESSAGE: Building for Linux/Mac...
Project ERROR: The python-config executable could not be found. Ensure
Python is installed and in the system path.

However, I've got python 2.7.10 installed and in the path.
I'm not a python expert, what am I missing?

Thanks,
Luca

Akin to Dave's response, perhaps your problem is that the installed python 
package is only complete if you are just running pure Python code against it, 
whereas if you are building anything C-level against Python eg some kind of 
extension then you would need a python-devel like package to give you the 
relevant C header files which you otherwise don't have. -- Darren Duncan

Hello Luca,

Try using apt-file:

sudo apt-get install apt-file
sudo apt-file update
sudo apt-file search python-config

And you will get a list with the package and filenames ... from which probably you'll need "python-dev"

Cheers,
Csaba

I've installed python 3.5 from the official site, and I can now run
the qmake straight. However, during the make I got:

Server.o: In function `Server::~Server()':
Server.cpp:(.text+0x1f): undefined reference to `Py_Finalize'
Server.o: In function `Server::run()':

and then I'm stucked.

Thanks for the hint: that lead me to package python-dev.
However, during the building I got:

While it compiles with python 2.7 it does not with 3.5.1 (I report
this in the case it is useful):

Hello,

I'm not an expert on this, but I would start with this line:
"undefined reference to symbol 'pthread_sigmask@@GLIBC_2.2.5'"
