We are trying to run Alsys Ada on an HP UNIX box as follows: Machine: HP9000/850 OS: HP-UX 7.0 Compiler Version: A.04.35 The installation of the compiler seemed to go smoothly, but when more than one person attempts to create a user library (using the "ada.mklib" command), then it appears that the first person to successfully create a user library "locks out" the others and actually becomes the temporary 'owner' of the system libraries (in particular predeflib and alternate in the 'installation' family). Any further attempts to create a user library by any other user (except the new 'owner') fail until the new 'owner' removes his user library (with "ada.rmlib"). Unfortunately, the behaviour of this locking is erratic and it can take 4 users creating 3 user libraries each to show up the problem on one day or just 2 users with 1 user library each on another day. Fixes that I've tried and failed with: 1) Re-installing the compiler (either by just running HP's "customize" script supplied with their release of Alsys Ada or redoing the stuff from scratch). 2) Using the "ada.protect -r" command to set the predeflib and alternate libraries to Read_Only (they're strangely shipped with Update_Allowed) ...this makes no difference either way. 3) Running on a different 800 series model (a 635) or trying the 300 series copy of Alsys Ada A.04.35. Doesn't seem to make any difference again. My question is this: has anyone else with a similar setup had problems like this with Alsys Ada ? And if you have, can you please supply any workarounds that you have (preferably to me directly) ? Richard K.
