32bit test fails on when built with -D_TIME_BITS=64 #216

Closed kabe-gh closed 8 months ago

kabe-gh commented 1 year ago

on 32bit environment with -D_TIME_BITS=64 -D_FILE_OFFSET_BITS-64, /usr/bin/meson test fails as below. Attached patch seems to fix this, but a dirty hack; maybe should left out as open issue.

patch-time64.patch

kabe-gh commented 1 year ago

Additional patch for compiling in chroot environment invoked by setarch i686. patch-nobypass-selinux.patch

martinpitt commented 1 year ago

on 32bit environment with -D_TIME_BITS=64 -D_FILE_OFFSET_BITS-64,

How exactly do you build this? The BITS-64 is apparently a typo, but:

$ meson setup /tmp/t64 --buildtype debug --prefix /usr --werror -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64
meson.build:1:0: ERROR: Unknown options: "_FILE_OFFSET_BITS, _TIME_BITS"

$ CFLAGS="-D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64" meson setup /tmp/t64 --buildtype debug --prefix /usr --werror &&  meson test -C /tmp/t64/
...
/usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
   26 | #   error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"

I get the same failure with

--- meson.build
+++ meson.build

+add_project_arguments('-D_FILE_OFFSET_BITS=64', language: 'c')

 meson.add_dist_script(srcdir / 'getversion.sh')

So I think the CFLAGS= approach works in general.

I tried this in current Debian testing i386. So how exactly did you try this?

kabe-gh commented 1 year ago

CFLAGS="-D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64" meson . redhat-linux-build meson compile -C redhat-linux-build --verbose

emits following error as you saw:

So, first, add #undef _TIME_BITS in src/libumockdev-preload.c:

Now meson compile will pass. Do the test:
