Problem to access singleton class object.

[sumit15nov]

Hi,
I am getting error to access singleton class object
please check the directory structure -

/home/user_name/src/component/osim
/home/user_name/src/oa/hal

now in this mode class diagram is -
osimbmsim is inherited from hal
hal <-- osimbmsim

there is a "server" class into /src/component/osim

inside this server i have written a function from where I am trying to get the instance of hal class, (hal is a singleton class) and from this instance I am calling the function of osimbmsim.

in server class I have included <hal/hal.h> and <osimbmsim.h>, because of this this is not able to find all the included header files in hal.

please give me some solution , I am trying since last night.

Thanks for help.
Sumit

Hi,

please check the directory structure -

/home/user_name/src/component/osim
/home/user_name/src/oa/hal

Looks like two directories with a common root (/home/user_name/src).

now in this mode class diagram is -
osimbmsim is inherited from hal
hal <-- osimbmsim

there is a "server" class into /src/component/osim

inside this server i have written a function from where I am trying
to get the instance of hal class, (hal is a singleton class) and from
thisinstance I am calling the function of osimbmsim.

in server class I have included <hal/hal.h> and <osimbmsim.h>,
because of this this is not able to find all the included header
files in hal.

The beginning of your solution is described in the FAQ. See section 5
and especially the question (and the answer) 5.8. You can find the FAQ
list here: http://www.parashift.com/c++-faq-lite/

Also, singletons and ways to implement them are a well-researched topic,
and you can find plenty of examples on the web. Try www.google.com
with an appropriate search phrase.

This is not within your directory structure.
Maybe you should omit the first /
or use the full directory path /home/user_name/src/component/osim
