GNU Smalltalk on ARM - Raspberry Pi

Hi everyone,

Is GNU Smalltalk likely to run on a Raspberry Pi?

I started installing it just in case, in FreeBSD 10-Stable on a Raspberry Pi.

The configure stage is tripping up over libltdl with the following error:
checking for GNUTLS... yes
checking for lt_dlopen in -lltdl... no
configure: error: libltdl is required to compile GNU Smalltalk

The libltdl package is in fact installed...
[root@raspberry-pi ~]# ls /usr/local/lib/ | grep tdl
libltdl.a
libltdl.la
libltdl.so
libltdl.so.7
libltdl.so.7.3.0

If someone could help me get past this, much appreciated. The compiler on this OS is clang 3.4.

Thanks
Stephen

Though not RPi, my trial on BeagleBone Black (on ArchLinux) works.
It seems that configure script only searches /usr.

the nice thing about autoconf is that it creates a config.log. My guess
is that it doesn't look in /usr/local/lib itself. Did you set LDFLAGS and
point it to /usr/local/lib?

I started a build on FreeBSD -CURRENT and yes you need something like

setenv LDFLAGS "-L/usr/local/lib -lexecinfo"
setenc CPPFLAGS "-I/usr/local/include"

(the need for CPPFLAGS is a bug, the need for -lexecinfo is a bug
as well. "backtrace" is new FreeBSD10 and we need to update our
autoconf tests)

You will need to install libffi, zip, flex, bison and libgmp as well
and you will need to use "gmake" instead of BSD make.

There are some test failures on FreeBSD as well but I didn't have the
time to check the source of them. Could you help with that?

Exactly the information needed and I was able to build the software.

The "gmake install" process crashed about four times, then it suddenly worked and went through to completion. I haven't gone back yet to see whether this was a repeatable GST build issue, or something else.

Good point

The result of running the test suite is below.
Yes for sure, I can check the source. I had a quick look at the test scripts and I have a couple of questions:-
1. How does one run a test file in isolation - is it possible? For instance what is the command to run just the tests in "intmath.st"?
2. With regard to the "intmath.st" test in the test output below, what is the "33" in "FAILED (testsuite.at:33)". The 33rd line? The 33rd test?

Thanks Holger for your assistance to get GST installed on the Pi. Much appreciated.

I had these failures on AMD64 and FreeBSD -CURRENT. I have to check if that
is either a Linux/FreeBSD or gcc/clang thing. It might still be a gmp vs.
no gmp issue.



This is odd. This might be due ARM differences. GNU Smalltalk doesn't use a
read/write barrier but we mprotect pages and expect a SIGSEGV when these are
being read/written to. It might be that libsigsegv is behaving differently on
FreeBSD.

You could attempt to use "--disable-generational-gc" and if that doesn't make
it more stable you can head to libgst/oop.h and uncomment the define from the
below fragment. If it works better we have an idea where we can look at.

/* Define this flag to disable blacking of grey pages (that is, the
   entire oldspace is scanned to look for reachable newspace objects).
   This is also necessary to run valgrind on GNU Smalltalk.  */
/* #define NO_SIGSEGV_HANDLING */

Have just used --disable-generational-gc and there was no change in the test suite. So now have uninstalled, cleaned, and am recompiling with the recommendation below. I have not used the --disable-generational-gc option in this next install.
Takes about an hour and a half round trip from compiling through to uninstalled, so yeah, theres time for a cup of coffee.

By the way, how does one check one of the test files outside of 'make check', .e.g to check intmath.st without running the whole test suite

For my case, in BeagleBone Black(ARM7, as far as I know) on ArchLinux; the
make check reports only 1 unexpected
error (refer attached testsuite.log for details)

Exactly the same pattern of tests failed as before, i.e. no benefit observed from making this change.

odd. You might want to get a backtrace then.

$ ulimit -c unlimited
$ run the command that failed
and if it crash
$ libtool --mode=execute gdb ./gst core.???? (replace ??? with something)

You can change to the test directory and execute the ./testsuite script
directly. It takes the "-v" for verbose argument and "-k NAME" to execute
a test by name.

AMD64/FreeBSD-9.2 has fewer issues.

Iconv/Seaside are the same failure. I thought I had fixed ICONV on FreeBSD
already but there might be another issue and the complex testcase is failing
with:

ComplexTest>>#testRaisedTo ....
FAILURE: Assertion failed

But in general this test result looks a lot better than the FreeBSD10/-CURRENT
one.

Testing on FreeBSD 10.0-RELEASE x64.
I found:-
  1. make check gives the same test results as when I ran it on the Pi, i.e. numbers tests failing, along with a few others
        2. as you can see below, the intmath.st test fails. However it does not crash with a core dump.

Hi Holger… I didn’t hear back from you, and I had to proceed with something so I did the project in another language.

I do have the Pi still with FeeBSD on it, although it has been wiped and re-imaged since that post.

I hope you give GNU Smalltalk another chance. I haven't much
progressed with GST on FreeBSD (leave alone the ARM port) but
I don't think it is something very big. My personal priority
is the Linux/ARM JIT thanks to Paulo's work.

kind regards

For sure, I’ve been using GNU smalltalk for scripting bits and pieces for a long time - on Intel CPUs. This was the first attempt to use it on FreeBSD/ARM, and love to have some time one day, and go a bit deeper to see what the problem is.

Cheers

I’ve just installed GNU Smalltalk on FreeBSD 10.1 on a Raspberry Pi. I used latest sources as at 26-Jan-2015.

All tests passed except for the FloatD and FloatE classes which failed a test. The test that failed is in floatmath.st, line 275...
        self assert: (self coerce: p reciprocal negated) negative.
where p is as follows;
   p := 1 bitShift: 1 + self precision - self emin.


To assist with resolving the bug, here are some examples from a GST session on the Pi:-

st > | p |
st> p := 1 bitShift: 1 + FloatD precision - FloatD emin.
