           Summary: make targets info-gcc, dvi-gcc etc. should work from
                    unbuilt configured tree
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rwild@gcc.gnu.org


Running configure and then 'make info-gcc' currently fails with:

make[1]: Entering directory `/tmp/build/gcc'
make[1]: Circular s-tm-texi <- ../../gcc/gcc/doc/tm.texi dependency dropped.
build/genhooks \
            ../../gcc/gcc/doc/tm.texi.in > tmp-tm.texi
/bin/sh: line 1: build/genhooks: No such file or directory
make[1]: *** [s-tm-texi] Error 127


It should not be necessary to 'make all' before this.  Likewise for the other
toplevel doc targets.

I think this is required for building the release tar ball.  And maybe even the
pdf daily.

I don't see where this would be a recent regression though. FWIW,
maintainer-scripts/update_web_docs_svn does not use 'make' for anything.

Did it really work in 4.5?  Thus, why's this a regression?

Yes, this used to work.  The difference between the 4.5 branch and trunk is
that now we have a generated gcc/doc/tm.texi from its .in file, and that
creating/updating tm.texi requires build/genhooks to be present.

Anyway, fixed.
