 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?

At DANCE we have a similar issue. We are still doing "software

with direct accessto the trigger logic), and we apply a time stamp

When I wrote the musbstd.h "open" method, I kind of punted on the problem of

If a variable under "/experiment/edit on start/" is an array, it is correctly
offered for editing on the "start run page", but then all elements in the array
end up set to the value of the first element.

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 |
