Yocto错误-aarch64 oe linux gcc:错误：AM_CFLAGS:没有这样的文件或目录

我在编译yocto上的bitbake文件时遇到了一个问题。我面临如下所述的错误

|aarch64 oe linux gcc:错误：AM\u CFLAGS:没有这样的文件或目录 |aarch64 oe linux gcc:错误：+=：没有这样的文件或目录

我的bitbake文件如下所示：

inherit autotools qcommon

FILESPATH =+ "${WORKSPACE}:"
SRC_URI = "file://video/bin/mm-video-internal/"

SRCREV = "${AUTOREV}"
S      = "${WORKDIR}/video/bin/mm-video-internal/"

PR = "r0"

PACKAGES = "${PN}"

DEPENDS = "glib-2.0 libxml2"

export TARGET_LIBRARY_SUPPRESS_LIST="libxml2"

EXTRA_OEMAKE += "DISABLE_GPU_UTF_PQ=true"

CFLAGS += "-I${STAGING_INCDIR}/libxml2/"
CFLAGS += "-include string.h"
CFLAGS += "-Dstrlcpy=g_strlcpy"
CFLAGS += "-Dstrlcat=g_strlcat"

LDFLAGS += "-lglib-2.0"
LDFLAGS += "-llog"
LDFLAGS += "-lxml2"

EXTRA_OEMAKE = "DEFAULT_INCLUDES= CFLAGS="-I. -I${STAGING_KERNEL_BUILDDIR}/usr/include -I${STAGING_KERNEL_BUILDDIR}/include -I${STAGING_INCDIR}/libxml2 -I${WORKSPACE}/kernel/msm-4.4/include/ -I${STAGING_KERNEL_DIR}/include/""

读者们能帮助我吗。

我在Makefile.am中犯了一个错误，我已经改正了。重复的调幅
