Definitely helpful for developer but not for user of an application developed with Pharo. I know I am probably the only one facing this situation, developing desktop applications with Pharo but VM packages does not solve my problem.

Re: [Pharo-dev] 32 bits and 64 bits VM
For me shipping the VM with the application eases the installation by the user and the production of release. The alternative will be to build a .debian package of Drgeo with only the image, then do the same for each ubuntu version (the two last ubuntu LTS have different approach for 32 bits compatibilty, so debian installation script need to be different). Of course, work need to be duplicated for the different Linux systems, probably the most popular only, but still will close the door to distribution I do not provide package. I just can't cope with that.

Re: [Pharo-dev] 32 bits and 64 bits VM
* 64-bit aware hashing functions as the current ones are 32-bit centric. This issue might not be the most urgent because the 32 bit hash functions should be sufficient to deal with at least moderately sized 64 bit images. But how much stuff would you have to allocate before seeing a problem? Suppose object headers are 16 bytes and your hash functions are producing 28 bits' worth of data. Clearly hashing 2^28 objects with zero instance variables and zero byte data is kind of silly, so we put in at least one instance variable making those objects at least 24 bytes. Then you also need a hashed collection with a single table large enough to hold all those objects (ignoring e.g. hash buckets), the load factor of which will be kept at 80%. So... 24 * 2^28 * 4 // 5 + (2^28 * 8) = about 7gb So, the current hash functions should be fine for images up to 7gb in size, and probably much larger than that because 7gb is the rock bottom low estimate. Probably one might hash strings or other objects with more data than 8 bytes. In that case, the low bound in that case will be higher. Andres.

Re: [Pharo-dev] 32 bits and 64 bits VM
Hello, The work to port Pharo to 64 bits has started. The new memory manager Spur will be ported to Pharo 4 alpha next week and it supports 64 bits (this is fresh news, it has been decided 3 hours ago). This was one of the main issue for the 64 bits port. Now the status is to finish to port the memory manager and to compile the VM for 64 bits. There is a bit a debugging to do as even if the 64bits Spur memory manager is implemented it has never been debugged. In addition, some plugins are 32 bits dependent and that needs to be fixed. At this point, which should be in the late summer if Esteban and Eliot are very productive, we should have a 64 bits stack VM. Then there are 2 remaining points, one is to port the JIT to support x86_64 bits and the other is to add faster floating pointer in 64 bits. Adding fast floating pointer is important as 64bits images are typically 30% slower than 32bits ones due to Pharo computation being mainly pointers computation, and that manipulating 64 bits is more expensive than 32 bits. At this point, which is probably around christmas if everything goes well, we should have a 64bits Cog VM. Now this is the optimistic planning. It may be that we have the 64 bits Stack VM for Christmas and the 64 bits Cog VM in a year. It depends if you prefer the optimistic or the pessimistic planning. Right now, people have issue with 64bits vs 32bits in Linux (I saw several reports on the mailing list) but it seems it is not a problem in Windows and Mac.

Re: [Pharo-dev] 32 bits and 64 bits VM

The new memory manager Spur will be ported to Pharo 4 alpha next week and it supports 64 bits (this is fresh news, it has been decided 3 hours ago). This was one of the main issue for the 64 bits port. Now the status is to finish to port the memory manager and to compile the VM for 64 bits. There is a bit a debugging to do as even if the 64bits Spur memory manager is implemented it has never been debugged. In addition, some plugins are 32 bits dependent and that needs to be fixed. At this point, which should be in the late summer if Esteban and Eliot are very productive, we should have a 64 bits stack VM. Then there are 2 remaining points, one is to port the JIT to support x86_64 bits and the other is to add faster floating pointer in 64 bits. Adding fast floating pointer is important as 64bits images are typically 30% slower than 32bits ones due to Pharo computation being mainly pointers computation, and that manipulating 64 bits is more expensive than 32 bits. At this point, which is probably around christmas if everything goes well, we should have a 64bits Cog VM. Now this is the optimistic planning. It may be that we have the 64 bits Stack VM for Christmas and the 64 bits Cog VM in a year. It depends if you prefer the optimistic or the pessimistic planning. Right now, people have issue with 64bits vs 32bits in Linux (I saw several reports on the mailing list) but it seems it is not a problem in Windows and Mac. Microsoft and Apple may be providing better support for 32 bits. I don't know. Keypad works on my linux build. There was a lost commit somewhere and I fwded the file to Esteban for integration. Phil I don't know about the working keypad. Perhaps someone more aware could help. 2014-05-14 21:08 GMT+02:00 Hilaire Fernandes hilaire.fernan...@gmail.com : Yesterday my boss asked me to see DrGeo on his Ununtu 14.04LTS 64 bits machine.

Please try sudo dpkg --add-architecture i386 and then apt-get update and then try to install again. I noticed that a few weeks before, told it Damien and he immediately put it on the website to prevent exactly your situation. Please reconsider looking at http://www.pharo-project.org/pharo-download/ubuntu and tell me if it is working.
