[Libguestfs] [PATCH] build: build C sources using OCaml API with CAML_NAME_SPACE
This way no non-namespaced OCaml C symbols are used, reducing the risk of clashes with other code. The only exception is ocaml-augeas, which does not build with CAML_NAME_SPACE; it will be fixed upstream, and it affects only ocaml-augeas itself. --- builder/Makefile.am | 2 ++ common/mllibvirt/Makefile.am | 1 + common/mlpcre/Makefile.am | 1 + common/mlprogress/Makefile.am | 1 + common/mltools/Makefile.am | 1 + common/mlutils/Makefile.am | 1 + common/mlvisit/Makefile.am | 1 + common/mlxml/Makefile.am | 1 + customize/Makefile.am | 1 + daemon/Makefile.am | 2 ++ ocaml/Makefile.am | 1 + v2v/Makefile.am | 2 ++ 12 files changed, 15 insertions(+) diff --git a/builder/Makefile.am b/builder/Makefile.am index b564fadd6..c7caec5cb 100644 --- a/builder/Makefile.am +++ b/builder/Makefile.am @@ -135,6 +135,7 @@ bin_PROGRAMS += virt-builder virt-builder-repository virt_builder_SOURCES = $(SOURCES_C) virt_builder_CPPFLAGS = \ + -DCAML_NAME_SPACE \ -I$(builddir) -I$(srcdir) \ -I$(top_builddir) \ -I$(top_srcdir)/gnulib/lib -I$(top_builddir)/gnulib/lib \ @@ -156,6 +157,7 @@ XOBJECTS = $(BOBJECTS:.cmo=.cmx) virt_builder_repository_SOURCES = $(REPOSITORY_SOURCES_C) virt_builder_repository_CPPFLAGS = \ + -DCAML_NAME_SPACE \ -I$(builddir) -I$(srcdir) \ -I$(top_builddir) \ -I$(top_srcdir)/gnulib/lib -I$(top_builddir)/gnulib/lib \ diff --git a/common/mllibvirt/Makefile.am b/common/mllibvirt/Makefile.am index 12e046c35..181cb9c5c 100644 --- a/common/mllibvirt/Makefile.am +++ b/common/mllibvirt/Makefile.am @@ -59,6 +59,7 @@ noinst_DATA = $(MLLIBVIRT_CMA) libmllibvirt_a_SOURCES = $(SOURCES_C) libmllibvirt_a_CPPFLAGS = \ + -DCAML_NAME_SPACE \ -I. \ -I$(top_builddir) \ -I$(shell $(OCAMLC) -where) diff --git a/common/mlpcre/Makefile.am b/common/mlpcre/Makefile.am index 6f04256da..1e0b7795c 100644 --- a/common/mlpcre/Makefile.am +++ b/common/mlpcre/Makefile.am @@ -49,6 +49,7 @@ noinst_DATA = $(MLPCRE_CMA) libmlpcre_a_SOURCES = $(SOURCES_C) libmlpcre_a_CPPFLAGS = \ + -DCAML_NAME_SPACE \ -I. \ -I$(top_builddir) \ -I$(top_srcdir)/gnulib/lib -I$(top_builddir)/gnulib/lib \ diff --git a/common/mlprogress/Makefile.am b/common/mlprogress/Makefile.am index 9c5ef9baf..d807f6cc8 100644 --- a/common/mlprogress/Makefile.am +++ b/common/mlprogress/Makefile.am @@ -50,6 +50,7 @@ noinst_DATA = $(MLPROGRESS_CMA) libmlprogress_a_SOURCES = $(SOURCES_C) libmlprogress_a_CPPFLAGS = \ + -DCAML_NAME_SPACE \ -I. \ -I$(top_builddir) \ -I$(top_srcdir)/gnulib/lib -I$(top_builddir)/gnulib/lib \ diff --git a/common/mltools/Makefile.am b/common/mltools/Makefile.am index ae78b84b7..ba8630033 100644 --- a/common/mltools/Makefile.am +++ b/common/mltools/Makefile.am @@ -87,6 +87,7 @@ noinst_DATA = $(MLTOOLS_CMA) libmltools_a_SOURCES = $(SOURCES_C) libmltools_a_CPPFLAGS = \ + -DCAML_NAME_SPACE \ -I. \ -I$(top_builddir) \ -I$(top_srcdir)/gnulib/lib -I$(top_builddir)/gnulib/lib \ diff --git a/common/mlutils/Makefile.am b/common/mlutils/Makefile.am index 45f401268..e86d7bb5f 100644 --- a/common/mlutils/Makefile.am +++ b/common/mlutils/Makefile.am @@ -54,6 +54,7 @@ noinst_DATA = $(MLCUTILS_CMA) # shouldn't be located under lib.
