[PATCH 2/2] Cygwin: configure: Add option to disable building 'dumper'
Rather than guessing, based on just the presence of libbfd, add an explicit configuration option, to build dumper or not, defaulting to building it. This might have some use when bootstrapping Cygwin for a new architecture, or when building your own Cygwin-targetted cross-compiler, rather than installing one from the copr, along with the dependencies of libbfd. --- winsup/configure.ac| 8 +--- winsup/doc/faq-programming.xml | 3 ++- 2 files changed, 7 insertions(+), 4 deletions(-) diff --git a/winsup/configure.ac b/winsup/configure.ac index 9205a8886..7a2121dae 100644 --- a/winsup/configure.ac +++ b/winsup/configure.ac @@ -111,10 +111,12 @@ AM_CONDITIONAL(CROSS_BOOTSTRAP, [test "x$with_cross_bootstrap" != "xyes"]) AC_EXEEXT -AC_CHECK_LIB([bfd], [bfd_init], [true], -AC_MSG_WARN([Not building dumper.exe since some required libraries or headers are missing])) +AC_ARG_ENABLE([dumper], + [AS_HELP_STRING([--disable-dumper], [do not build the 'dumper' utility])], + [build_dumper=$enableval], + [build_dumper=yes]) -AM_CONDITIONAL(BUILD_DUMPER, [test "x$ac_cv_lib_bfd_bfd_init" = "xyes"]) +AM_CONDITIONAL(BUILD_DUMPER, [test "x$build_dumper" = "xyes"]) AC_CONFIG_FILES([ Makefile diff --git a/winsup/doc/faq-programming.xml b/winsup/doc/faq-programming.xml index a24b781cf..24c7f928e 100644 --- a/winsup/doc/faq-programming.xml +++ b/winsup/doc/faq-programming.xml @@ -685,7 +685,8 @@ installed; you at least need gcc-g++, Additionally, building the dumper utility requires gettext-devel, libiconv-devel -zlib-devel. +zlib-devel.

It would be great if we could get used to using the same syntax as the

Yeah, core.abbrev is 12 digits. I'm using this setting for quite some
time locally.
Sounds good. Is there some script to automate generating this kind of
comment from a commit-id?
I don't think so, at least I don't see anything like that in git docs...
It's note _quite_ what you asked for, but `git show --pretty=reference -s
` (https://git-scm.com/docs/git-show#_pretty_formats) gives you
_almost_ what you are looking for.
But you can always call `git show -s --format='%h ("%s")' `, and
even configure an alias for this:
git config --global alias.pretty-print-commit \
"-c core.abbrev=12 show -s --format='%h (\"%s\")'"
Thanks!
I added '-c core.pager=', but this is what I was looking for, to save a
bit of copying and pasting and editing.
Better use `git -P`, then... (see
https://git-scm.com/docs/git#Documentation/git.txt--P for full details)
I started off with that, but that fails when used with:
fatal: alias 'pretty-print-commit' changes environment variables.
You can use '!git' in the alias to do this
... which I'm sure tells me the right way to write this :)

Thanks, Corinna
