Greetings, I tried running the tests with: make bootstrap make -k check and it fails like this: make[5]: Entering directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic' make all-recursive make[6]: Entering directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic' Making all in testsuite make[7]: Entering directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic/testsuite' make[7]: Nothing to be done for 'all'. make[7]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic/testsuite' make[7]: Entering directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic' true DO=all multi-do # make make[7]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic' make[6]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic' make[5]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/32/libatomic' make[4]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/libatomic' make[3]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/libatomic' make[2]: Leaving directory '/home/nick/gcc/obdjir/x86_64-pc-linux-gnu/libatomic' make[1]: Target 'check-target' not remade because of errors. make[1]: Leaving directory '/home/nick/gcc/obdjir' Makefile:2292: recipe for target 'do-check' failed make: *** [do-check] Error 2 make: Target 'check' not remade because of errors. I have no idea why but I added this very minor fix: error_at (EXPR_LOCATION (call_expr), "cannot tail-call: %s", _(reason)); The only odd thing about this build is I am running it through ccache but I have no idea how that would cause issues. Thoughts? Nick
