Re: [Help-smalltalk] GNU Smalltalk on ARM - Raspberry Pi

[Stephen Woolerton]

If this helps, with regard to the the failure of all the ANSI tests... on 
running make check, I see:-
...
cd . && /usr/local/src/smalltalk-master/tests/gst -S 
--image=/usr/local/src/smalltalk-master/tests/gst.im AnsiLoad.st
Loading Ansi.st
ld-elf.so.1: assert failed: /usr/src/libexec/rtld-elf/rtld_lock.c:233
gmake[2]: *** [gst.im] Abort trap (core dumped)
gmake[2]: *** Deleting file `gst.im'

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
