[Gambas-user] 64 bits version

[Benoit Minisini]

Hi,

Thanks to the ssh access on the 64 bits Ubuntu system of Rob Kudla, I could 
fix enough things, and now everything compiles, the installation works, and 
the development environment runs.

But testing more is difficult, as running an X11 program through ssh is slow. 
So I invite "64 bits people" to test again and send the result on the 
developer mailing-list.

Now, let's talk about 'valgrind'.

Valgrind is an extraordinary program that emulates a processor. You run your 
program in it, and valgrind will check every memory access at the byte 
granularity. 

It can even tell you how fast each piece of your program is, by taking the 
different CPU caches into account. Thanks to valgrind, I could make the 
Gambas compiler twice faster.

By running some examples with valgrind, I got a lot of memory access errors 
inside the gnu C library, and in the dynamic loader library too. 

I don't know if these errors are really significant. They could be valgrind 
bugs. 

But it is perfectly possible that the program does not crash even with such 
memory errors, because the Linux granularity is 4Kb (the size of a page), not 
a single byte.

So, if something crashes during the installation, or during the startup of 
examples or IDE, please try valgrind and send me its output.

Using valgrind is easy. Go to the project directory, and run:
$ valgrind gbx3 -p

Thanks in advance for any help.

Regards,
