i'm using python 3.4.4 on centos7.

i've created python program on local machine makes use of qt modules. program running fine on local machine. i'm trying create executable pyinstaller. i'm using command:

i'm getting following output:

does know issue be? have python3-devel , python-devel installed (in relation suggestion @ end of printed output.) thanks

you must install python-dev python's version

for example:

debian/ubuntu - python 2.7 ---> python2.7-dev

centos/redhat - python 3.4 ---> python34-devel

centos/redhat - python 2.7 ---> python27-devel

one of these errors can puzzling, however: ioerror("python library not found!") pyinstaller needs bundle python library, main part of python interpreter, linked dynamic load library. name , location of file varies depending on platform in use. python installations not include dynamic python library default (a static-linked 1 may present cannot used). may need install development package of kind. or, library may exist not in folder pyinstaller searching.

the places pyinstaller looks python library different in different operating systems, /lib , /usr/lib checked in systems. if cannot put python library there, try setting correct path in environment variable ld_library_path in linux or dyld_library_path in os x.
