That test meant that $UAPI had to point to a linux-evl source directory and could not point to installed headers in e.g. /usr/include. The script had previously allowed the use of installed headers, using the existence of $UAPI/Kbuild as an heuristic to decide whether $UAPI pointed to linux-evl source or to installed headers. Rewrite the script to check for the existence of all three required directories in either location. This allows the use of installed headers again. Fixes: c70a9d9 (build: tighten consistency check for uapi) Signed-off-by: Evan Gates --- Changes in v3: - Add Signed-off-by trailer Changes in v2: - Switch back to Kbuild heuristic in order to check/set the correct path for the asm directory - Add the missing directory back to the error message - Actually test with both setups, not sure how I messed that up last time meson/setup-uapi.sh | 28 ++++++++++++++-------------- 1 file changed, 14 insertions(+), 14 deletions(-) diff --git a/meson/setup-uapi.sh b/meson/setup-uapi.sh index 1b43c02..f27a07e 100644 --- a/meson/setup-uapi.sh +++ b/meson/setup-uapi.sh @@ -1,19 +1,19 @@ #! /bin/sh -if test \! -d $UAPI/include/uapi/evl; then - echo "meson: path given to -Duapi does not look right ($UAPI/include/uapi/evl is missing)" - exit 1 +if test -r $UAPI/Kbuild; then + set \ + $UAPI/arch/$ARCH/include/uapi/asm \ + $UAPI/include/uapi/asm-generic \ + $UAPI/include/uapi/evl +else + set $UAPI/asm $UAPI/asm-generic $UAPI/evl fi -mkdir -p $O_UAPI -rm -f $O_UAPI/asm $O_UAPI/asm-generic $O_UAPI/evl +for d do + test -d $d && continue + echo "meson: path given to -Duapi does not look right ($d is missing)" + exit 1 +done -if test -r $UAPI/Kbuild; then - ln -s $UAPI/arch/$ARCH/include/uapi/asm $O_UAPI/asm - ln -s $UAPI/include/uapi/asm-generic $O_UAPI/asm-generic - ln -s $UAPI/include/uapi/evl $O_UAPI/evl -elif test \! -L $O_UAPI/asm; then - ln -s $UAPI/asm $O_UAPI/asm - ln -s $UAPI/asm-generic $O_UAPI/asm-generic - ln -s $UAPI/evl $O_UAPI/evl -fi +mkdir -p $O_UAPI +for d do ln -sf $d $O_UAPI/; done -- 2.35.1
