 18 May 2006, Stefan Ritt, Bug Fix, Fixed problems with reload of custom pages
|
We had a problem with custom pages and reloading of them. If they contain an ODB field which is editable, one can change the ODB value through the custom
page. The URL then contains a "?cmd=Set&value=x&index=x" section, which stays in the browser's address bar after the ODB value has been updated. If the
value changes later by some other means in the ODB, and one presses "reload" in the browser, the above URL gets executed again and the value gets changed |

18 May 2006, Konstantin Olchanski, Bug Fix, removed a few "//" comments to fix compilation on VxWorks
|
Our VxWorks C compiler (gcc-2.8-something) does not like the "//" comments. Luckily, on VxWorks, we
only compile a small subset of midas, so there is no point in banning all "//" comments. But I did have to
convert a couple of them to /* commens */ in odb.c to make it compile. Changes to odb.c commited. K.O. |

11 May 2006, Konstantin Olchanski, Bug Report, MIDAS and Fedora 4
|
Fellow Midasites- we are receiving reports that current Midas sources do not compile on Fedora 4 (and 5?)
with errors "invalid lvalue in assignment". It looks like the new compilers reject what looks to my eye like
perfectly valid C code that we have been writing since the beginning of C. Any suggestions on the best fix?

02 Dec 2005, Greg Hackman, Info, MIDAS on Cygwin
|
If you want to run MIDAS on Cygwin, make sure you have cygserver running. First set a Windows system environment variable CYGWIN=server. This is best
done through the Control Panel -> System -> Advanced -> Environment Variables. Then run /usr/bin/cygserver-config in a Cygwin console window. Then reboot.
After that your MIDAS executables should run properly.

[quote="Stefan Ritt"]We have both the example experiment and the MSCB Makefile which both expect to find the midas drivers under [b]$MIDASSYS/drivers/camac[/b]

requires to put all drivers then under [b]/usr/local/drivers[/b], which is not the case in the current Makefile for midas. Do you think that we should |
