bbappend file for replacing a file
I created a new layer in yocto: meta-abc, a recipe: abc-efg_0.1.bb and an .bbapend: abc-efg_01.bbapend file. With the bbappend file I want to overwrite a file from intel-edison board. More exactly, the wpa_supplicant.conf from /etc/wpa_supplicant/. This wpa_supplicant.conf is already created from another layer (meta-intel-edison-distro). I can write my file in /etc/ so my recipe and my bbappend file are working. I can bitbake my recipe, but when I try to creat the image I receive the message:
" * check_data_file_clashes: Package abc-efg wants to install file /home/atr-int/Desktop/Yocto/yocto-edison/build_edison/tmp/work/edison-poky-linux/edison-image/1.0-r0/rootfs/etc/wpa_supplicant/wpa_supplicant.conf But that file is already provided by package * wpa-supplicant * opkg_install_cmd: Cannot install package abc-etc. " Here is my bbappend file content:
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI += "file://wpa_supplicant.conf"
do_install_append() {
install -d ${D}${sysconfdir}/wpa_supplicant
install -m 0755 ${WORKDIR}/wpa_supplicant.conf
${D}${sysconfdir}/wpa_supplicant
}
Can anyone give my any tip ? Thank you.
Answer
You shouldn't rewrite the wpa_supplicant.conf from another recipe, as the files will clash.
Instead, rename your abc-efg_01.bbapend to wpa-supplicant_%.bbappend, and it should work.
If for some reason you need to have wpa_supplicant.conf in abc-efg, you need to add a wpa-supplicant_%.bbappend in which you'll need to remove wpa_supplicant.conf.
