I followed the http://libguestfs.org/guestfs-building.1.html to build source. git clone https://github.com/libguestfs/libguestfs cd libguestfs ./autogen.sh make I installed the lib I didn't have it and everything is ok untill I enter *make* I got error message: > CCLD libguestfs.la > ar: `u' modifier ignored since `D' is the default (see `U') > make[3]: Leaving directory '/home/pahome/git/libguestfs/lib' > make[2]: Leaving directory '/home/pahome/git/libguestfs/lib' > Making all in docs > make[2]: Entering directory '/home/pahome/git/libguestfs/docs' > make[2]: Nothing to be done for 'all'. > make[2]: Leaving directory '/home/pahome/git/libguestfs/docs' > Making all in examples > make[2]: Entering directory '/home/pahome/git/libguestfs/examples' > CCLD create-disk > ../lib/.libs/libguestfs.so: undefined reference to `yajl_tree_free' > ../lib/.libs/libguestfs.so: undefined reference to `yajl_tree_parse' > collect2: error: ld returned 1 exit status > Makefile:1926: recipe for target 'create-disk' failed > make[2]: *** [create-disk] Error 1 > make[2]: Leaving directory '/home/pahome/git/libguestfs/examples' > Makefile:1975: recipe for target 'all-recursive' failed > make[1]: *** [all-recursive] Error 1 > make[1]: Leaving directory '/home/pahome/git/libguestfs' > Makefile:1884: recipe for target 'all' why is *undefined reference to 'yajl_tree_parse'*, I already install it from https://github.com/lloyd/yajl

[PATCH] common/mlstdutils: Fix parallel builds of bytes.ml.

by Richard W.M. Jones

From: "Richard W.M. Jones" <rjones(a)redhat.com> With OCaml < 4.02 when using the alternate Bytes module, this module would be compiled twice during parallel builds, resulting in occasional corruption. The reason for this is that the ocamldep file mentions ‘bytes.cmo’ whereas the ‘$(OCAML_BYTES_COMPAT_ML)’ macro expands to ‘../../common/mlstdutils/bytes.ml’. Make doesn't recognize these as the same file. Use an alternate way to specify this file to fix this. --- common/mlstdutils/Makefile.am | 9 +++++++-- m4/guestfs_ocaml.m4 | 2 ++ 2 files changed, 9 insertions(+), 2 deletions(-) diff --git a/common/mlstdutils/Makefile.am b/common/mlstdutils/Makefile.am index 968a03d..e569154 100644 --- a/common/mlstdutils/Makefile.am +++ b/common/mlstdutils/Makefile.am @@ -27,9 +27,14 @@ SOURCES_MLI = \ stringMap.mli \ stringSet.mli -SOURCES_ML = \ +if HAVE_BYTES_COMPAT_ML +SOURCES_ML = bytes.ml +else +SOURCES_ML = +endif + +SOURCES_ML += \ guestfs_config.ml \ - $(OCAML_BYTES_COMPAT_ML) \ libdir.ml \ stringMap.ml \ stringSet.ml \ diff --git a/m4/guestfs_ocaml.m4 b/m4/guestfs_ocaml.m4 index a7334cd..d0f3349 100644 --- a/m4/guestfs_ocaml.m4 +++ b/m4/guestfs_ocaml.m4 @@ -123,6 +123,8 @@ EOF ]) AC_SUBST([OCAML_BYTES_COMPAT_CMO]) AC_SUBST([OCAML_BYTES_COMPAT_ML]) +AM_CONDITIONAL([HAVE_BYTES_COMPAT_ML], + [test "x$OCAML_BYTES_COMPAT_ML" != "x"]) dnl Flags we want to pass to every OCaml compiler call.

[PATCH v2] common/mlstdutils: Build a bytecode version of this library.

by Richard W.M. Jones

Even if ocamlopt is available, always build a bytecode version of ‘common/mlstdutils’. Furthermore, because this library is pure OCaml, we should not be using ‘ocamlmklib’. We should use ‘ocaml{c,opt} -a’ instead. This doesn't make any difference for native code, but for bytecode it was building a broken library. The original reason for making this change is because the generator is always built as bytecode, and it depended on ‘../common/mlstdutils/guestfs_config.cmo’ and ‘../common/mlstdutils/std_utils.cmo’. On native code platforms these were not built before the generator and so the generator races to build the .cmi and .cmo files. Since the generator doesn't have correct dependencies covering the ‘common/mlstdutils’ directory you can get a broken link on fast machines: File "../common/mlstdutils/std_utils.ml", line 1: Error: Corrupted compiled interface ../common/mlstdutils/guestfs_config.cmi make[2]: *** [Makefile:1993: ../common/mlstdutils/std_utils.cmo] Error 2 make[2]: *** Waiting for unfinished jobs.... make[2]: Leaving directory '/builddir/build/BUILD/libguestfs-1.37.17/generator' --- common/mlstdutils/Makefile.am | 11 ++++++++--- generator/Makefile.am | 9 ++++++--- 2 files changed, 14 insertions(+), 6 deletions(-) diff --git a/common/mlstdutils/Makefile.am b/common/mlstdutils/Makefile.am index 9e0b34d42..67441f769 100644 --- a/common/mlstdutils/Makefile.am +++ b/common/mlstdutils/Makefile.am @@ -48,7 +48,9 @@ else MLSTDUTILS_CMA = mlstdutils.cmxa endif -noinst_DATA = $(MLSTDUTILS_CMA) +# Just for this library, we need to build both bytecode and native +# code because the generator always requires the bytecode version. +noinst_DATA = mlstdutils.cma mlstdutils.cmxa libmlstdutils_a_SOURCES = dummy.c libmlstdutils_a_CPPFLAGS = \ @@ -79,8 +81,11 @@ endif libmlstdutils_a_DEPENDENCIES = $(OBJECTS) -$(MLSTDUTILS_CMA): $(OBJECTS) - $(OCAMLFIND) mklib $(OCAMLPACKAGES) $(OBJECTS) -o mlstdutils +mlstdutils.cma: $(BOBJECTS) + $(OCAMLFIND) ocamlc $(OCAMLPACKAGES) -a $^ -o $@ + +mlstdutils.cmxa: $(XOBJECTS) + $(OCAMLFIND) ocamlopt $(OCAMLPACKAGES) -a $^ -o $@ # This OCaml module has to be generated by make (configure will put # unexpanded prefix macro in). diff --git a/generator/Makefile.am b/generator/Makefile.am index 3f54ad51d..d4a21fe97 100644 --- a/generator/Makefile.am +++ b/generator/Makefile.am @@ -115,8 +115,6 @@ sources = \ # In build dependency order. objects = \ $(OCAML_BYTES_COMPAT_CMO) \ - ../common/mlstdutils/guestfs_config.cmo \ - ../common/mlstdutils/std_utils.cmo \ types.cmo \ utils.cmo \ proc_nr.cmo \ @@ -180,7 +178,12 @@ noinst_PROGRAM = generator if HAVE_OCAML generator: $(objects) - $(OCAMLFIND) ocamlc $(OCAMLFLAGS) $(OCAMLPACKAGES) -linkpkg $^ -o $@ +# We need the recursive make here because the generator is +# rebuilt in ‘make clean’. + $(MAKE) -C $(top_builddir)/common/mlstdutils mlstdutils.cma + $(OCAMLFIND) ocamlc $(OCAMLFLAGS) \ + $(OCAMLPACKAGES) -linkpkg mlstdutils.cma \ + $^ -o $@ # Dependencies. depend: .depend -- 2.13.2

by Richard W.M. Jones

Previously posted as part of the mega utilities/inspection series here: https://www.redhat.com/archives/libguestfs/2017-June/msg00232.html What I've done is to extract just the parts related to rewriting daemon APIs in OCaml, rebase them on top of the current master, fix a few things, and recompile and test everything.

[PATCH] common/mlutils: Remove bogus suffix parameter from Mkdtemp.temp_dir.

by Richard W.M. Jones

The C function mkdtemp(3) requires that the string ends with 6 'X' characters, so appending a non-empty suffix causes the function to raise EINVAL.

I have rebased against current OCaml daemon patch series, modified the patch to use the new Chroot.create API, and retested. Rich.

This depends on the patch series "[PATCH 00/27] Reimplement many daemon APIs in OCaml." (https://www.redhat.com/archives/libguestfs/2017-July/msg00098.html) v8 was posted here: https://www.redhat.com/archives/libguestfs/2017-June/msg00274.html v9: - I split up the mega-patch into a more reviewable series of smaller, incremental patches. There are some other changes vs v8, but they are insignificant cleanups and one bug fix. Rich.
