While trying to compile gtkmm sample code on my Solaris10 machine, I am getting some compile time error in glibmm/variant.h header.
System Configuration is as below:
> uname -a
> SunOS selix570bx 5.10 Generic_150401-04 i86pc i386 i86pc
Compiler version is as below:
> CC -V
> CC: Sun C++ 5.8 2005/10/13
Source Code (sample.cc) is as below:
#include <gtkmm.h>
int main(int argc, char *argv[])
{
Gtk::Main kit(argc, argv);
Gtk::Window window;
Gtk::Main::run(window);
return 0;
}
Command to compile the source is as below:
> CC -library=stlport4 sample.cc -o sample `pkg-config gtkmm-2.4 --cflags --libs`
Output of pkg-config command is as below for reference:
> pkg-config gtkmm-2.4 --cflags --libs

Below is the error I am getting while compiling my sample gtkmm code:

Compilation aborted, too many Error messages.
Earlier I got few more error messages including the above errors but most of those errors went away by including -library=stlport4.
Now, are these errors because my compiler did not support c++11 as I am on a older solaris10 system. But I choose gtkmm2.4 because I thought it works with older version of C++ compiler also. Also I tried checking if in case I am using a newer version of glibmm. But the currently installed glibmm is only one available in package manager for my system.
Not sure where to look further to resolve this issue. Any suggestions.
The issue got resolved by doing the following changes:
I installed the latest g++ available for my Solaris system using below command:
> /opt/csw/bin/pkgutil -a | grep g++
gcc4g++ CSWgcc4g++ 4.9.2,REV=2014.11.07 41.9 MB
gcc5g++ CSWgcc5g++ 5.2.0,REV=2015.07.31 57.2 MB
> /opt/csw/bin/pkgutil -i -y gcc5g++
It installed few libraries and new g++ in /opt/csw/gcc5/bin/ directory. Now, instead of using Sun Solaris Compiler I used this new g++ compiler and everything worked fine.
But before compiling with g++ I have to set LD_LIBRARY_PATH as below:
setenv LD_LIBRARY_PATH /opt/csw/lib
As with new g++ compiler some libraries also got downloaded which got placed in above directory.
Yayyy. :)
