yocto项目-配方sysroot中缺少依赖项

大概所有的yocto人都知道yocto rocko 2.4+中sysrootfs策略已更改。因此,我遇到以下问题:我尝试使用makefile为共享库制作配方。配方如下(我不声称它是完整的。我只是无法通过构建阶段):

#==================
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://${THISDIR}/files/LICENSE;md5=5959e502cb44bafc53b2cc9400e3d4cd"
PR = "r0"

##### First try from my local repo and then we will use the big one
SRC_URI = "git:///home/w23698/projects/anybus/Generic;branch=anybus-lib-0.0.1"
SRCREV = "2fe4ce39a651d71f3f8de1c751dff2581de2c526"

S = "${WORKDIR}/git"

PACKAGES = "${PN} ${PN}-dev ${PN}-dbg"
#####The only dependency 
RDEPENDS_${PN} = "libgpiod"
RDEPENDS_${PN}-dev = "libgpiod"
RDEPENDS_${PN}-dbg = "libgpiod"

do_compile() {
    oe_runmake
}

do_install() {
    install -d ${D}${libdir}
    install -m 0644 ${PN}-m40 ${D}${libdir}
}

失败后,我感到惊讶的是

 ww.c:6:10: fatal error: gpiod.h: No such file or directory 
 |  #include "gpiod.h"
 |           ^~~~~~~~~
 | compilation terminated.

然后我注意到命令行是:

arm-poky-linux-gnueabi-gcc  -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/<full path>/recipe-sysroot -L/usr/lib -g -Wall -fpic .....

我查看了recipe-sysroot/usr/lib/,发现最小的库集和libgpiod都不存在。标头中都没有include ...

有什么建议吗?

答案 0 :(得分:1)

您从未设置DEPENDS = libgpiod。

您设置的RDEPENDS是运行时所依赖的,因此与编译时无关。您只需删除这些链接,因为库链接依赖关系将自动生成。
