unable to install omniidl in RHEL 7

Question

I am trying to install omniORB in RHEL 7.5. I get the below error when I run the make command. I guess to resolve this , I will have to install omniidl.

../../../../../src/tool/omniidl/cxx/idlpython.cc:31:26: fatal error: Python.h: No such file or directory

include PYTHON_INCLUDE

                      ^

compilation terminated. make[4]: *** [idlpython.o] Error 1 make[4]: Leaving directory /var/omniORB/omniORB-4.2.4/build/src/tool/omniidl/cxx' make[3]: *** [export] Error 1 make[3]: Leaving directory /var/omniORB/omniORB-4.2.4/build/src/tool/omniidl' make[2]: *** [export] Error 1 make[2]: Leaving directory /var/omniORB/omniORB-4.2.4/build/src/tool' make[1]: *** [export] Error 1 make[1]: Leaving directory /var/omniORB/omniORB-4.2.4/build/src' make: *** [all] Error 1

I'm not sure, but maybe an interpreter can't deal with such path ../../../ . Try to use an absolute path instead. For example:

In[2]: import os 
In[3]: os.getcwd()
Out[3]: '/home/pc/PycharmProjects/test_project'
In[4]: os.path.abspath('../test.txt')
Out[4]: '/home/pc/PycharmProjects/test.txt'

I this example I have a file test.txt outside of current dir test_project
