General Questions

Where do I find the bleeding-edge version of APPSPACK?
The development version is available online and is updated nightly. Go to http://software.sandia.gov/appspack/dev.
Why am I getting errors like
Warning - no output file for the point corresponding to tag=1
when the executable name is specified correctly in the .apps input file?
Such warning statements typically mean that APPSPACK is unable to find your executable. There are several options the user can take in order to provide APPSPACK the correct executable path.
1. Run appspack from the location of the executable, e.g.,
```
% cd /home/user/appspack/examples/
% ../src/appspack_serial example1.apps
```
2. Specify the full path name for your executable in your .apps, e.g.,
```
"Executable Name" string "/home/user/appspack/examples/example1"
```
3. Add the directory containting your executable to your PATH environment variable.
  - In bash:
```
export PATH=$PATH:/home/user/appspack/examples/
```
  - In tcsh:
```
setenv PATH ${PATH}:/home/user/appspack/examples/
```
