When I compile current cvs-head midas, I get errors about undefined function
min(). I do not think min() is in the list of standard C functions, so
something else should be used instead, like a MIN(a,b) macro. To make life
more interesting, in a few places, there is also a variable called "min".
Here is the error:

src/mana.c: In function `INT write_event_ascii(FILE*, EVENT_HEADER*, 
   ANALYZE_REQUEST*)':
src/mana.c:2571: `min' undeclared (first use this function)
src/mana.c:2571: (Each undeclared identifier is reported only once for each 
   function it appears in.)
make: *** [linux/lib/rmana.o] Error 1

This is really a miracle to me. The min/max macros are defined both in midas.h
and msystem.h and worked the last ten years or so. However, I agree that macros
should follow the standard and use capital letters, so I changed that.

I commited Makefile bits to set the RPATH on dynamically linked executables
to find libmidas.so and ROOT shared libraries without setting
LD_LIBRARY_PATH , etc. K.O.

The problem is that /usr/include/c++/3.*/bits/stl_algobase.h contains 
#undef min
#undef max

and in C++ with STL one should really use something like this
    std::min<INT>(a,b)

Is the midas CVS server set-up so that I can pull the newest 
version off the CVS server?

What would be my CVSROOT?
pserver:anoncvs@midas.psi.ch:/cvs/midas *this did not work* :)

In the Midas doc under "Quick Start"
http://midas.triumf.ca/doc/html/quickstart.html
you will find the proper cvs command for accessing the latest cvs Midas
version. The public pwd is cvs. You will only be able to checkout/update the
package.

Could anyone give me some hints. Thanks!

The current (cvs) version of MIDAS should build on Mac OS X right out of the
box- I fixed all the problems you report back in February(?)- see the macosx
thread in this forum. A few weeks ago I verified that it still compiles on Mac
OS 10.3.4. The Mac OS port received minimal testing- I checked that "odbedit"
and "mhttpd" run, that's about it. K.O.

I cannot checkout module:

Could anybody add download tar package in the WWW interface of CVS repository.
I know the original CGI script has such a feature. Thanks.

Thanks a lot. But I cannot checkout module:

I know the original CGI script has such a feature. Thanks.

P.S.
I use these commands to checkout:
   cvs -e ssh -d :ext:cvs@midas.psi.ch:/usr/local/cvsroot checkout midas
   cvs -e ssh -d :ext:cvs@midas.psi.ch:/usr/local/cvsroot update

Should work fine, just tried from outside PSI. Please check again.

The tar package is only done for a new release (which will happen in the next days
BTW), so http://midas.psi.ch/download/tar/ contains the most recent packages. Upon
request I make a midas-snapshot.tar.gz, but since there will be a 1.9.4 soon, it's
maybe not necessary right now.

Unfortunately, I still encounter the same problem.

pc2075.psi.ch: Operation timed out
cvs [checkout aborted]: end of file from server (consult above messages if any)

I am in LNS-INFN (Italy), i.e., I am outside PSI. So ... what's the problem? I try to
ping the host, and it is reachable:
--------
[exaos@exaos cvsnew]$ ping midas.psi.ch

Is it the problem of firewall? I am not sure. So strange.

Waiting for the new release ...

What does '-rpath' mean? It is just a linking error. Thanks.

Fixed. Good catch.

> What does '-rpath' mean?

You will have to read the "ld" manual. In the nutshell, it tells the executable where to look for shared libraries. 
Aparently it is not supported by Mac OS X.

K.O.

I use:

setenv CVS_RSH ssh
cvs -d cvs@midas.psi.ch:/usr/local/cvsroot checkout midas

It works most of the time. Sometimes I get locking and "permission denied"
errors on some subdirectories, presumably when CVS is being reorganized or
when there are stale locks. Does not happen too often.

K.O.

Hi,
 I am really puzzled: I am running the very same as far as sources
are concerned (Dec 12, 2003 snapsot) midas frontend (miniexp + camacnul)
on two different machines (and the same trusted private network):

1) one is an ancient Pentium/100 MHz laptop with RedHat Linux 7.3 and 
2) another one is event more ancient MVME167 25MHz running VxWorks 5.4.2

The front end on my Linux PC works just fine, whereas on the MVME167
I get intermittent crashes (most often at the end of the run).
[Correction: the crashes happen, I think, when the frontend wants 
to update the ODB]

The crashes happen in db_set_record routines

Any ideas what might be wrong? 
Except that MVME167 is a piece of ...#@!% 

Piotr

A followup: I traced back the problem to version 1.9.2.

Version 1.9.1 does not have this problem but 1.9.2 does. 
For now I stick with 1.9.1

Piotr
 

Starting from midas version 1.9.4 on, the environment variable 'MIDASSYS'
should be defined and point to the installation directory of midas. The
purpose of that is that add-on packages (like the upcoming ROME system) can
find the midas libraries and include files. It is excatly the same as for
ROOT which defines ROOTSYS and should therefore be straight forward. The
libraries should then reside in $MIDASSYS/lib (or %MIDASSYS%\lib under windows).

To remind users about this new variable, a test has been added to odbedit,
which shows a warning when starting odbedit and MIDASSYS is not defined.

Version 1.9.4 of midas has been released today. It is mainly a maintenance
update, for all the little things which have been fixed since the last
release, and does not contain major new functionality.

1. Finally! It's about time to do that! 

2. What will the entire structure tree look like?

Here's my suggestion
MIDASSYS=/opt/midas-1.9.4 (for example)   


so the Linux binaries would go to 
MIDASHOST=i386-pc-linux-gnu
$MIDASSYS/$MIDASHOST/bin
$MIDASSYS/$MIDASHOST/lib

the VxWorks binaries
MIDASHOST=m68k-wrs-vxworks
$MIDASSYS/$MIDASHOST/bin
$MIDASSYS/$MIDASHOST/lib

and the shared stuff would go to 
$MIDASSYS/include
$MIDASSYS/share/drivers
$MIDASSYS/share/examples

The Makefile would need to be adjusted (for make install) but that is not
too complicated

What do you think?

Regards
  Piotr
