MCStas

[Andrew Garrett]

Kristian,

  Thanks for getting back to me so quickly, I'd like to get this working.  Pity it
wasn't the #line comments, I had high hopes for that being it, since it looked
fairly easy to fix...  One mis-communication, though.  I don't have a compiler
error, the program compiles just fine (under Boorland C++ 4.52, BTW)  I had to
replace the srtcasecmp statements, but can handle alloca without any problems.

  The problem comes when I run the program, calling MCStas with an instrument file -
I'm using linup-1, from your examples directory, renamed linup1.ins to avoid long
name problems.  I get an "illegal operation error" after starting the program,
nothing more specific than that, I'm afraid.  By inserting printf's into the main
program, I've been trying to track down where this occurs.

  In general, but not always, the program gets to the line in main(), 'err =
yyparse();'  I cannot get the program to compile if I put printf's inside yyparse()
though.  When seraching for the component, it does make one call to
try_open_component, and tries to find a file with a .comp extension, but then it
fails after that, without making a second call.

  I'm still working on this, and will keep you informed.  If you've got any ideas,
please let me know.  Thanks,

  Andrew Garrett
