Loading CMPR for UNIX

UNIX Loading Instructions for CMPR

Here is an outline of the steps needed to install CMPR on your computer. Report problems to Brian Toby.

Install the Tcl/Tk and BLT packages and optionally the Tix package (Click here for instructions.)
Note that not all distributions of BLT will load properly with the tcl "package require" command and nearly all versions have an incorrect pkgIndex.tcl file.

Create a directory for CMPR:

                mkdir cmpr
                cd cmpr

Download ftp://ftp.ncnr.nist.gov/pub/cryst/powdersuite/cmpr_dist.tar.Z

Restore the compressed tar file:

                zcat cmpr_dist.tar.Z | tar xvf -

Select a platform (LINUX or SGI) and compile by typing

                make linux

                make sgi

Make a shortcut to CMPR so that you can access it by typing cmpr rather than a longer command. Choose one from the two methods below:
- Add an alias to your ~/.cshrc file, type:
```
                cat >> ~/.cshrc
                alias tkgsas "wish /usr/local/cmpr/cmpr.tcl"
                ^D
```
- Install a script in the on your system path. Another way to simplify access is to create a file which will execute the cmpr.tcl script from a command in your system's path, for example /usr/bin.
```
                cat > /usr/bin/cmpr
                wish /usr/local/cmpr/cmpr.tcl
                ^D
                chmod +x /usr/bin/cmpr
```
Note that in the above commands ^D means control-D. If wish has been installed in a non-standard location on your system, you will probably need to modify the above. Click here for more information.

To use CMPR on another type of computer, you will likely have to edit the file src/Makefile and then use the command make make. If you don't have access to FORTRAN compiler, you can download and use the binary versions of the FORTRAN programs for SGI and LINUX, which are included in the following tar files.

Download the appropriate file and expand it in the same directory as before (zcat cmpr_sgi_binary.tar | tar xvf - or zcat cmpr_linux_binary.tar | tar xvf -)

Common Problems

CMPR reports an error: "Error -- Unable to load the BLT package" and exists after the OK button is pressed.
You do not have BLT installed in the right place so that it can be loaded with a "package require" command. Click here for instructions on installing the Tcl/Tk and BLT packages.
I get an error message saying: invalid command name "Blt_ZoomStack". (In CMPR version 1.4 and later, you will get a message saying "Error in BLT support routines: invalid command name Blt_ZoomStack")
The routines in BLT's pkgIndex.tcl file do not reference the routines in the bltGraph.tcl file. This is a bug that never seems to get fixed. See my notes at the end of tclpkgs80.html to see how to change the pkgIndex.tcl file.

CMPR is written by Brian H. Toby of the NIST Center for Neutron Research. Small FORTRAN programs used in CMPR contain routines borrowed from lots of sources: The reflection generation code traces back to the NIST AIDS*83 (C. Hubbard, J. Stalick, A. Mighell & others), space group extinctions from NRC symmetry codes (A. C. Larson) and peak fitting uses GPLSFTA (D. Cox, W. Hamilton, L. Finger & many others).
