Another problem while using odbedit.
I tried the batch mode of "odbedit". I created a key as "/A_Str" by mistake and
wanted to delete it. Then "odbedit" failed to accept the "Return" key. Please see

03 Sep 2009, Exaos Lee, Suggestion, Building MIDAS using CMake

I write some configure file to build MIDAS using CMake. The usage is simple:
1. Unzip the attachment, copy "CMakeLists.txt" and directory "cmake" into the
midas source tree.
|
|
03 Sep 2009, Exaos Lee, Suggestion, Some screenshot using CMake with MIDAS

I didn't add optimization flags to compile, so I got link error while generating mcnaf as I reported before.
The screen-shots show that the configure files works because I have modified the "driver/camac/camacrpc.c". |

The INLINE statements are a relict from times where a subroutine call was in the order of a few microseconds. This was when you probably were pretty young, |

We have seen on several daq systems this problem: we start a run and observe that the number of
