In doing so, it left a very corner-case along. When the target is an ARM CPU and the build is in thumb mode, then we want to ensure that libglib2 is still built in arm mode (because of inline asm). But with meson, CFLAGS from the environment are passed to the host compiler, so the build breaks, and the meson log contains: Appending CFLAGS from environment: '-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -marm' No LDFLAGS in the environment, not changing global flags. No CPPFLAGS in the environment, not changing global flags. Sanity testing C compiler: cc Is cross compiler: False. Sanity check compiler command line: cc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -marm [...]/build/libglib2-2.60.4/build/meson-private/sanitycheckc.c -o [...]/build/libglib2-2.60.4/build/meson-private/sanitycheckc.exe Sanity check compile stdout: ----- Sanity check compile stderr: cc: error: unrecognized command line option ‘-marm’; did you mean ‘-mabm’? ----- meson.build:1:0: ERROR: Compiler cc can not compile programs. Fix that by using the new per-package CFLAGS feature of the meson infra. Signed-off-by: Yann E.
