Installing GPSIM

Hi there., nowadays I'm playing around with micro controllers. Before to get involve with MCUs physically I wanted to try it virtually. As a Linux user I Googled for a linux software to simulate my MCU programs. I found out a software GPSIM (GNU PIC Simulator). But while I'm building the GPSIM I met with a problem and googled for the solution. Unfortunately there wasn't. So I get on to work and got a solution my self.  

Basically it's required to install following dependencies before.

gputils (GNU PIC Utils)
sdcc (Small Device C Compiler)

Then it's time to build and install the GPSIM

while I'm executing the ./configure I met with a problem. first there popt.h file missing. so I have to install package included that header file. and then the biggest problem was occurred.

                     To install gpsim, it's required to be installed gtkextra-2.0 package.

I couldn't find out the gtkextra-2.0. Instead of that I have installed gtkextra-3.0

But while I configuring, terminal prompts an Error.

checking for pkg-config... /usr/bin/pkg-config
configure: error: Cannot find gtkextra-2.0 package

Although there's  no problem with gtkextra package I examined the source code of the configure file. I saw that there's a code in the configure file which is shown below

$PKGCONFIG --exists gtkextra-2.0

  if test $? != 0; then

    as_fn_error $? "Cannot find gtkextra-2.0 package" "$LINENO" 5

  fi

  X_LDFLAGS=`$PKGCONFIG --libs gtk+-2.0 gthread-2.0`

  X_CFLAGS=`$PKGCONFIG --cflags gtk+-2.0`

  Y_LDFLAGS=`$PKGCONFIG --libs gtkextra-2.0`

  Y_CFLAGS=`$PKGCONFIG --cflags gtkextra-2.0`

  GTK_VERSION_T=`$PKGCONFIG --modversion gtk+-2.0`

this code always search for the older version of the gtkextra package even computer has it's latest version. So I replaced 'gtkextra-2.0' with 'gtkextra-3.0'

Note: Keep a copy of the Configure file before you edit it.
Note: You cannot edit it without root privileges. So use

                     $ sudo gedit configure

Note: Always replace your currently running gtkextra package version. It's  gtkextra-3.0 in my case. To find out version of yours

               $ pkg-config --list-all | grep gtk

Note: install any other dependencies. In my case I had missing packages libpopt-dev (for popt.h)

Then I was able to get through the configuration process painlessly. Then executed

           $ sudo make

           $ sudo make install

I thought that it's almost done. But it wasn't, an error was prompted.

~/gpsim-0.26.1$ gpsim
gpsim: error while loading shared libraries: libgtkextra-x11-3.0.so.1: cannot open shared object file: No such file or directory


Searched for the missing package 'libgtkextra-x11-3.0' library and downloaded the built packages

libgtkextra-x11-3.0-0   and libgtkextra-x11-3.0-dev


installed sequently

$ sudo dpkg -i libgtkextra-x11-3.0-0_3.0-0ubuntu3_i386.deb

$ sudo dpkg -i libgtkextra-x11-3.0-dev_3.0-0ubuntu3_i386.deb

then it works without any trouble ...  :D
