Hi Eugene,

it's good news that somebody is finally working on the cross-compilation part. 
As for the segfault, it is difficult to guess it from the strace. Are you 
using the old  garbage collector?

Also, if the compiler is linked in, it will try to locate a file 
(${libdir}/ecl/sysfun.lsp). If your machine cannot reach the files ECL needs, 
try removing the compiler from the code by commenting out the :lisp-files 
line in build/compile.lsp:
(compiler::build-program
 #+(or cross stage1) "ecl"
 #-(or cross stage1) "ecl2"
;; :lisp-files '(#+(and (not dlopen) WANTS-CMP) cmp)
 :ld-flags '("-L./"))

Are there no remote debugging possibilities in this machine? If there are, 
then I could help you in debugging the error. But only after the 18th, 
because I have to travel tomorrow to another conference.

Best regards,

Juanjo
