Greetings, and thanks for your report! I would love to get gcl in cross-compiling shape, but as you note, even leaving one AC_RUN_IFELSE in place renders the whole process moot. Taking a quick glance, the most critical test appears to be GCL's configure time verification that it can unrandomize sbrk(). As far as I can tell this test at least would require running compiled binaries, so the only question remaining is whether we could do without it. This test has served as a very useful domino break for countless segfaults appearing mysteriously later as images are saved and reexecuted. If it is to be retained, the only alternative I can envision is a runtime startup test for every GCL image, but it is not clear to me if this could ever reliably be implemented, as each executable has a fixed, though random, sbrk() breakpoint even when the personality flags are broken.
I will try to think about this a bit more. Take care, -- Camm Maguire c...@maguirefamily.org ========================================================================== "The earth is but one country, and mankind its citizens." -- Baha'u'llah
