strace was easy to do, I have that attached. I haven't used gdb very much. Here's the initial "I figured out how to make it do something": (ins)efraim@g4:~/guile-static$ gdb -q ./bin/guile Reading symbols from ./bin/guile... (No debugging symbols found in ./bin/guile) (ins)(gdb) run Starting program: /home/efraim/guile-static/bin/guile guile: warning: failed to install locale Program received signal SIGSEGV, Segmentation fault. 0x10073d90 in ?? () I figured it was worth trying with other architectures, so I built %guile-static-stripped for x86_64-linux: ./pre-inst-env guix build -e '(@@ (gnu packages make-bootstrap) %guile-static-stripped)' but that one didn't have any problems. Now I'm building it for i686-linux. After that I'll try again with the bootstrap-tarballs, but i686-linux -> powerpc-linux and see if that changes anything. > Thanks, > Ludo’. -- Efraim Flashner <efr...@flashner.co.il> אפרים פלשנר GPG key = A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted
