When the list of packages to be installed in a built image exceeds a certain number, then 'opkg install' executed for target '$(curdir)/install' in package/Makefile fails with: /usr/bin/env: Argument list too long. On Linux, the length of a command-line parameter is limited by MAX_ARG_STRLEN to max 128 kB. * https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/binfmts.h#L15 * https://www.in-ulm.de/~mascheck/various/argmax/ To solve the problem, store the package list being passed to 'opkg install' in a temporary file and use the shell command substitution to pass the content of the file to 'opkg install'. This guarantees that the length of the command-line parameters passed to the bash shell is short. The following bash script demonstrates the problem: ---------------------------------------------------------------------------- count=${1:-1000} FILES="" a_file="/home/egorenar/Repositories/openwrt-rel/bin/targets/alpine/generic/packages/base-files_1414-r16464+19-e887049fbb_arm_cortex-a15_neon-vfpv4.ipk" for i in $(seq 1 $count); do FILES="$FILES $a_file" done env bash -c "echo $FILES >/dev/null" echo "$FILES" | wc -c ---------------------------------------------------------------------------- Test run: ---------------------------------------------------------------------------- $ ./test.sh 916 130989 $ ./test.sh 917 ./test.sh: line 14: /bin/env: Argument list too long 131132 ---------------------------------------------------------------------------- Signed-off-by: Alexander Egorenkov <egorenar-dev@posteo.net> [reword commit subject] Signed-off-by: Paul Spooren <mail@aparcar.org> |
