Bug #: 54586 Summary: Help diagnosing error: Link tests are not allowed after GCC_NO_EXECUTABLES Classification: Unclassified Product: gcc Version: 4.7.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other AssignedTo: unassig...@gcc.gnu.org ReportedBy: ba...@usgs.gov This is not a bug report, but a feature request. I have been struggling with building GCC cross compilers. When I unexpectedly encounter error: Link tests are not allowed after GCC_NO_EXECUTABLES, what I really need to do is find out which previous configure step broke and set gcc_no_link=yes. The "Link tests..." error is a consequence of the true error, which is not identified as having set gcc_no_link=yes. I have taken to hand editing configure files when this happens and inserting my own diagnostic output when either gcc_no_link=no or gcc_no_link=yes is executed, e.g., in libiberty/configure: # FIXME: Cleanup? if { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$ac_link\""; } >&5 (eval $ac_link) 2>&5 ac_status=$? $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5 test $ac_status = 0; }; then : $as_echo "$as_me:${as_lineno-$LINENO}: ---> gcc_no_link=no" >&5 gcc_no_link=no else $as_echo "$as_me:${as_lineno-$LINENO}: ---> gcc_no_link=yes" >&5 gcc_no_link=yes fi It would be really useful if all GCC configure files would emit such a message, at least when setting gcc_no_link=yes. It would make it a lot easier to trouble shoot "Link tests..." errors.
