Re: libstdc++ related bootstrap failure on Solaris

[Benjamin Kosnik <bkoz at redhat dot com>]

Ah ha! Thanks Gerald, I can now reproduce this:

I created a build directory called "bld-x86-gcc:today"

/mnt/hd/loha/bld-x86-gcc:today/i686-pc-linux-gnu/libstdc++-v3/src

Now fails with:

Making all in src
make[2]: Entering directory `/mnt/hd/loha/bld-x86-gcc:today/i686-pc-linux-gnu/libstdc++-v3/src'
Makefile:509: *** target pattern contains no `%'.  Stop.

Looking the makefile, I see line 509 as:

myinstallheaders: $(headers:%=$(myincludep)/%)  <--here
	if test -z "$(MULTISUBDIR)"; then \
	for i in $(std_headers); do \
	  echo "$(INSTALL_DATA) $(GLIBCPP_INCLUDE_DIR)/std/$$i $(myincludep)";\
	        $(INSTALL_DATA) $(GLIBCPP_INCLUDE_DIR)/std/$$i $(myincludep); \
	done; \
	for i in $(build_headers); do \
          echo "$(INSTALL_DATA) $(top_builddir)/include/$$i $(myincludep)/bits/"; \
	     $(INSTALL_DATA) $(top_builddir)/include/$$i $(myincludep)/bits/; \
	done; \
	libio_headers_install='$(libio_headers)'; \
	for i in $$libio_headers_install; do \
          echo "$(INSTALL_DATA) $$i $(myincludep)"; \
                $(INSTALL_DATA) $$i $(myincludep); \
	done; \
	fi;

Why am I not surprised that this part of the Makefile creates such
problems. I hate these hacky header install routines. Is there any
kind of shell-scripting magic that I can use to get around this at the
moment?
