Hi there,
I'm trying to build OpenWrt 23.05.2 with modifications, saved the .config file in a stripped way by running sed '/^[[:space:]]*#.*/ d; /^[[:space:]]*$/ d' .config > <my saved config file>. If I want to reuse that file the build system automagically enables packages even if I want to replace that package, in my case enables automagically and silently dnsmasq although I selected dnsmasq-full and logd although I selected syslog-ng. It's not amusing to get after 7 hours of build time data_file_clashes from bundling the binary 'cause I have to run the build on only one core and start with an as clean as possible environment, on multi-core build it throws a *** [tools/Makefile:222: /home/devuan/openwrt-kirkwood/staging_dir/host/stamp/.tools_compile_yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy] Error 2 after installing cmake-3.26.4 due to modified options, I haven't found out which one is responsible yet, without -j "$(("$(nproc)"+1))" it's building fine.
Although I think it doesn't matter here is my whole build process:
git clone https://git.openwrt.org/openwrt/openwrt.git "$OpenWrtRoot"/OpenWrt-Master
# git pull # if needed
git checkout v23.05.2
./scripts/feeds update -a
./scripts/feeds install -a
Now I got out of that directory and left it alone, and did as the same average user in my home directory:
OpenWrtRoot=/home/devuan/OpenWrt
Arch='-kirkwood'
BuildDate="$(date +%d.%m.%y-%H:%M)"
export WhichOpenWrt="openwrt$Arch"
export OpenWrtBuildLogDir="$PWD/${WhichOpenWrt}_build-log_$BuildDate"
mkdir -p "$PWD/$WhichOpenWrt/readwrite" "$PWD/$WhichOpenWrt/work" "$OpenWrtBuildLogDir"
sudo mount -t overlay overlay -o lowerdir="$OpenWrtRoot/OpenWrt-Master",upperdir="$PWD/$WhichOpenWrt/readwrite",workdir="$PWD/$WhichOpenWrt/work" "$PWD/$WhichOpenWrt"
cd "$WhichOpenWrt"
if [ ! -h dl -o ! -d dl ]; then ln -s "$OpenWrtRoot/Sources" dl; fi
cp "$OpenWrtRoot/config$Arch"-<my saved one> .config
make menuconfig
script -a "$OpenWrtBuildLogDir/buildscreen-output.log" -c 'make -j"$(("$(nproc)"+1))" V=s defconfig download clean world 2>&1 | tee -a "$OpenWrtBuildLogDir/build.log"
'Cause I wanna save some disk space the overlay mount, just copy or better tar / untar works the same, and 'cause I had trouble in the past with some build due to a not perfectly clean environment just redoing the mount gives me an as definite as possible build environment without having to redownload anything, that's why I'm doing it that way.
'Cause I have already configured that build properly and know ('cause I ran into that trap yesterday) that the config was in the above mentioned particular point correct I just copied it at the second build and just altered that step I wanna test out if it also builds (Yesterday without SE-Linux worked after I disabled dnsmasq and logd, today just enabled SE-Linux in that particular working prooved .config file and they both were automagically enabled again - which I noticed after building by running into that clashes...)
Is the .config file parsed partial in reverse so that some lines # <xxx> is not set are crucial? If so which one?
Hope you get puzzled out my stammering...
Best regards
Peter
PS: I can't copy the mentioned .config file here to a text box due to character limits, how to attach it directly as a file if you wanna have it?
