[Libguestfs] [PATCH] python: PYTHON_LIBS is not set in Python 3.8 (RHBZ#1705482).

Python 3.8 no longer links C extensions to -lpython, instead relying on the fact that the python binary itself already contains those symbols. This means $PYTHON_LIBS is empty and so the Python bindings are not built. Use a different test to see if the python module is available. --- m4/guestfs-python.m4 | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/m4/guestfs-python.m4 b/m4/guestfs-python.m4 index 7d4c991bb..befa9b102 100644 --- a/m4/guestfs-python.m4 +++ b/m4/guestfs-python.m4 @@ -33,14 +33,17 @@ AS_IF([test "x$enable_python" != "xno"],[ PYTHON_VERSION_MINOR=`$PYTHON -c "import sys; print (sys.version_info@<:@1@:>@)"` PYTHON_VERSION="$PYTHON_VERSION_MAJOR.$PYTHON_VERSION_MINOR" AC_MSG_RESULT([$PYTHON_VERSION]) + # Debian: python-2.7.pc, python-3.2.pc PKG_CHECK_MODULES([PYTHON], [python-"$PYTHON_VERSION"],[ + have_python_module=1 AC_SUBST([PYTHON_CFLAGS]) AC_SUBST([PYTHON_LIBS]) AC_SUBST([PYTHON_VERSION]) AC_DEFINE([HAVE_PYTHON],[1],[Python library found at compile time]) ],[ PKG_CHECK_MODULES([PYTHON], [python],[ + have_python_module=1 AC_SUBST([PYTHON_CFLAGS]) AC_SUBST([PYTHON_LIBS]) AC_SUBST([PYTHON_VERSION]) @@ -49,6 +52,7 @@ AS_IF([test "x$enable_python" != "xno"],[ AC_MSG_WARN([python $PYTHON_VERSION not found]) ]) ]) + AC_MSG_CHECKING([Python prefix]) PYTHON_PREFIX=`$PYTHON -c "import sys; print (sys.prefix)"` AC_MSG_RESULT([$PYTHON_PREFIX]) @@ -101,4 +105,4 @@ AS_IF([test "x$enable_python" != "xno"],[ AC_SUBST(PYTHON_EXT_SUFFIX) ]) AM_CONDITIONAL([HAVE_PYTHON], - [test "x$PYTHON" != "xno" && test "x$PYTHON_LIBS" != "x" ]) + [test "x$PYTHON" != "xno" && test "x$have_python_module" = "x1" ]) -- 2.21.0
