I had trouble compiling Splotch 4.0, but I quickly discovered the problem was a small typo in the source code. Once the typo was fixed, the program compiled successfully.  Upon running the program, I encountered another issue.  I investigated the code further and I found what appears to be the problem:  A variable is declared and then it is used before it is assigned a value.

I decided that version 4.0 is too buggy to use as I'm just starting out. I then compiled Splotch 3.1 with OpenMP support enabled.  The compilation was successful on the first try.  However, upon attempting to run the program with the data file and parameter file provided on the Splotch website, I encountered the error message

Cannot find the key "filegas_palette".

I explored the code for a while, but I haven't figured out how to solve this issue yet. I need to further modify the parameter file in some way, since it was written for the new 4.0 version of the code.  I'll need to read most of code and review C++ in order to learn everything I need to know about Splotch. There are many parameters which can be set, but there appears to be no detailed documentation as is provided with GADGET.

I suppose I should focus on writing the other proposals before I focus more on reading the source code.
