From ba4ba9711a1356909275196c2abfd33f7d0950a6 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 2 Dec 2021 23:13:15 -0500 Subject: [PATCH] libctf: workaround automake bug with conditional info pages It looks like automake makes assumptions about its ability to build info pages based on the GNU standard behavior of shipping info pages with the distributions. So even though the info pages were conditionalized, and automake disabled some of the targets, it was still creeping in by way of unconditional INFO_DEPS settings. We can workaround this by adding a stub target for the info page when building info pages are disabled. This tricks automake into disabling its own extended generation target. I'll follow up with the automake folks to see what they think. --- libctf/Makefile.am | 2 -- libctf/Makefile.in | 40 ++++++++++++++++++++++------------------ libctf/doc/local.mk | 10 ++++++++++ 3 files changed, 32 insertions(+), 20 deletions(-) diff --git a/libctf/Makefile.am b/libctf/Makefile.am index 3e51b7b30d0..8d317018556 100644 --- a/libctf/Makefile.am +++ b/libctf/Makefile.am @@ -114,6 +114,4 @@ EXTRA_DEJAGNU_SITE_CONFIG = development.exp DISTCLEANFILES += site.exp development.exp endif -if BUILD_INFO include doc/local.mk -endif diff --git a/libctf/Makefile.in b/libctf/Makefile.in index 379f50df44b..2b74bf2855e 100644 --- a/libctf/Makefile.in +++ b/libctf/Makefile.in @@ -1023,24 +1023,24 @@ doc/$(am__dirstamp): @$(MKDIR_P) doc @: > doc/$(am__dirstamp) -doc/ctf-spec.info: doc/ctf-spec.texi - @test -f doc/$(am__dirstamp) || $(MAKE) $(AM_MAKEFLAGS) doc/$(am__dirstamp) - $(AM_V_MAKEINFO)restore=: && backupdir="$(am__leading_dot)am$$$$" && \ - rm -rf $$backupdir && mkdir $$backupdir && \ - if ($(MAKEINFO) --version) >/dev/null 2>&1; then \ - for f in $@ $@-[0-9] $@-[0-9][0-9] $(@:.info=).i[0-9] $(@:.info=).i[0-9][0-9]; do \ - if test -f $$f; then mv $$f $$backupdir; restore=mv; else :; fi; \ - done; \ - else :; fi && \ - if $(MAKEINFO) $(AM_MAKEINFOFLAGS) $(MAKEINFOFLAGS) -I doc -I $(srcdir)/doc \ - -o $@ `test -f 'doc/ctf-spec.texi' || echo '$(srcdir)/'`doc/ctf-spec.texi; \ - then \ - rc=0; \ - else \ - rc=$$?; \ - $$restore $$backupdir/* `echo "./$@" | sed 's|[^/]*$$||'`; \ - fi; \ - rm -rf $$backupdir; exit $$rc +@BUILD_INFO_TRUE@doc/ctf-spec.info: doc/ctf-spec.texi +@BUILD_INFO_TRUE@ @test -f doc/$(am__dirstamp) || $(MAKE) $(AM_MAKEFLAGS) doc/$(am__dirstamp) +@BUILD_INFO_TRUE@ $(AM_V_MAKEINFO)restore=: && backupdir="$(am__leading_dot)am$$$$" && \ +@BUILD_INFO_TRUE@ rm -rf $$backupdir && mkdir $$backupdir && \ +@BUILD_INFO_TRUE@ if ($(MAKEINFO) --version) >/dev/null 2>&1; then \ +@BUILD_INFO_TRUE@ for f in $@ $@-[0-9] $@-[0-9][0-9] $(@:.info=).i[0-9] $(@:.info=).i[0-9][0-9]; do \ +@BUILD_INFO_TRUE@ if test -f $$f; then mv $$f $$backupdir; restore=mv; else :; fi; \ +@BUILD_INFO_TRUE@ done; \ +@BUILD_INFO_TRUE@ else :; fi && \ +@BUILD_INFO_TRUE@ if $(MAKEINFO) $(AM_MAKEINFOFLAGS) $(MAKEINFOFLAGS) -I doc -I $(srcdir)/doc \ +@BUILD_INFO_TRUE@ -o $@ `test -f 'doc/ctf-spec.texi' || echo '$(srcdir)/'`doc/ctf-spec.texi; \ +@BUILD_INFO_TRUE@ then \ +@BUILD_INFO_TRUE@ rc=0; \ +@BUILD_INFO_TRUE@ else \ +@BUILD_INFO_TRUE@ rc=$$?; \ +@BUILD_INFO_TRUE@ $$restore $$backupdir/* `echo "./$@" | sed 's|[^/]*$$||'`; \ +@BUILD_INFO_TRUE@ fi; \ +@BUILD_INFO_TRUE@ rm -rf $$backupdir; exit $$rc doc/ctf-spec.dvi: doc/ctf-spec.texi doc/$(am__dirstamp) $(AM_V_TEXI2DVI)TEXINPUTS="$(am__TEXINFO_TEX_DIR)$(PATH_SEPARATOR)$$TEXINPUTS" \ @@ -1709,6 +1709,10 @@ uninstall-am: uninstall-dvi-am uninstall-html-am \ @BUILD_INFO_TRUE@ $(AM_V_GEN)$(MAKEINFOHTML) $(AM_MAKEINFOHTMLFLAGS) $(MAKEINFOFLAGS) \ @BUILD_INFO_TRUE@ --split=node -I$(srcdir) --output doc/ctf-spec $(srcdir)/doc/ctf-spec.texi +# Workaround bug in automake: it can't handle conditionally building info pages +# since GNU projects normally include info pages in the source distributions. +@BUILD_INFO_FALSE@doc/ctf-spec.info: + # Tell versions [3.59,3.63) of GNU make to not export all variables. # Otherwise a system limit (for SysV at least) may be exceeded. .NOEXPORT: diff --git a/libctf/doc/local.mk b/libctf/doc/local.mk index 7ee2fec78cc..e533d72227d 100644 --- a/libctf/doc/local.mk +++ b/libctf/doc/local.mk @@ -17,6 +17,8 @@ # . # +if BUILD_INFO + info_TEXINFOS += %D%/ctf-spec.texi libctf_TEXINFOS = $(info_TEXINFOS) @@ -29,3 +31,11 @@ html-local: %D%/ctf-spec/index.html %D%/ctf-spec/index.html: %D%/ctf-spec.texi %D%/$(am__dirstamp) $(AM_V_GEN)$(MAKEINFOHTML) $(AM_MAKEINFOHTMLFLAGS) $(MAKEINFOFLAGS) \ --split=node -I$(srcdir) --output %D%/ctf-spec $(srcdir)/%D%/ctf-spec.texi + +else + +# Workaround bug in automake: it can't handle conditionally building info pages +# since GNU projects normally include info pages in the source distributions. +%D%/ctf-spec.info: + +endif -- 2.30.2
