C++ EZWindows Linker Errors when trying to run demos
- by Brent Nash
I'm attempting to download and use the EZWindows ( http://www.cs.virginia.edu/c++programdesign/software/ ) SPARC installation (the http://www.cs.virginia.edu/c++programdesign/software/EzWindows2a-SPARC.tar.gz file). When trying to build some of the examples that come with it, I'm getting some linker errors that I just can't figure out.
Here's the result of the uname -a command on the machine I'm running on (on which I am NOT an administrator):
SunOS AAA.BBB.edu 5.10 Generic_138888-07 sun4v sparc SUNW,T5240
And here is the result of the g++ -v command:
gcc version 2.95.2 19991024 (release)
If you untar/unzip the package, I'm trying to compile the example in samples/chap03/lawn by simply doing "gmake" in that directory, here's what I get. Here's the error I get:
bash-3.00$ gtar xfz EzWindows2a-SPARC.tar.gz

This particular run was built using g++ 2.95.2, but I've also tried with versions 3.3.2 and 4.2.1 with other equally strange errors. I'm pretty sure that EZWindows requires a 2.x version of gcc & g++. I've tried to make sure that my LD_LIBRARY_PATH and PATH are setup to include everything that's needed, but it seems that may be incorrect.
I'm running out of ideas. Anyone have any other ones?
