Re: [microblaze-uclinux] Re: [uClinux-dev] Ruby on uclinux
Hi, John,
Thanks a lot for your advice. I am doing a project of building a
platform that can emulate wide area distributed applications with a
number of FPGAs running CPUs like microblaze. The emulation is slow,
but we hope we can measure the interesting traffic patterns in the
network. Thus being able to run more software is more important than
performance / memory usage to us. If you are interested in our
project, you can find more details in my advisor's talk
http://radlab.cs.berkeley.edu/w/uploads/1/15/RAMPinRADS.pdf
Ruby is configured with ./configure, and I used CC=/path
to/ucfront-gcc , target=mb and --with-static-linked-ext. I have to
modify config.sub to make it recognize mb-linux (just adding the
names, and set default os of mb to be linux -- I am I right in doing
this?)
I tried to modified the resulting Makefile a little bit to let the
CFLAGS etc to be appened from the top level Makefile. I also build
the host miniruby required to run the ruby setup scripts before hand,
similar to the python build process.
The build process can be completed and the resulting ruby executable is
ruby: BFLT executable - version 4 ram
However, when I run it, I get
Allocation of length 1099927 from process 77 failed
Free pages: 249484kB ( 0kB HighMem)

121*2048kB = 249484kB)
= 0kB)
= 0kB)
Unable to allocate RAM for process text/data, errno 12
Do you know what happened? I think I encountered similar problems
when I try to build a few other applications. Here is part of my make
file, and resulting parameters to ld.
Thanks in advance,
Wei
