From: Helmut Grohne <helmut@xxxxxxxxxx> dtrace invokes the C compiler, so when cross-building we need to make sure that $CC is set in the environment and that it points to the cross-compiler rather than the native one. Until https://github.com/mesonbuild/meson/issues/266 is addressed, the workaround is to call dtrace via env(1). https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=980334 Signed-off-by: Helmut Grohne <helmut@xxxxxxxxxx> Reviewed-by: Andrea Bolognani <abologna@xxxxxxxxxx> --- meson.build | 1 + src/meson.build | 4 ++-- src/qemu/meson.build | 4 ++-- 3 files changed, 5 insertions(+), 4 deletions(-) diff --git a/meson.build b/meson.build index d8a63baac9..1c36b10390 100644 --- a/meson.build +++ b/meson.build @@ -2022,6 +2022,7 @@ if host_machine.system() == 'linux' if dtrace_prog.found() conf.set('WITH_DTRACE_PROBES', 1) endif + dtrace_command = [ 'env', 'CC=' + ' '.join(meson.get_compiler('c').cmd_array()), dtrace_prog ] endif if not get_option('host_validate').disabled() and host_machine.system() != 'windows' diff --git a/src/meson.build b/src/meson.build index 7c478219d6..56e71f4456 100644 --- a/src/meson.build +++ b/src/meson.build @@ -60,14 +60,14 @@ if conf.has('WITH_DTRACE_PROBES') out_h, input: infile, output: out_h, - command: [ dtrace_prog, '-o', '@OUTPUT@', '-h', '-s', '@INPUT@' ], + command: dtrace_command + [ '-o', '@OUTPUT@', '-h', '-s', '@INPUT@' ], ) dtrace_gen_objects += custom_target( out_o, input: infile, output: out_o, - command: [ dtrace_prog, '-o', '@OUTPUT@', '-G', '-s', '@INPUT@' ], + command: dtrace_command + [ '-o', '@OUTPUT@', '-G', '-s', '@INPUT@' ], ) custom_target( diff --git a/src/qemu/meson.build b/src/qemu/meson.build index 90640b03c6..e3065c3507 100644 --- a/src/qemu/meson.build +++ b/src/qemu/meson.build @@ -56,14 +56,14 @@ if conf.has('WITH_DTRACE_PROBES') out_h, input: infile, output: out_h, - command: [ dtrace_prog, '-o', '@OUTPUT@', '-h', '-s', '@INPUT@' ], + command: dtrace_command + [ '-o', '@OUTPUT@', '-h', '-s', '@INPUT@' ], ) qemu_dtrace_gen_objects += custom_target( out_o, input: infile, output: out_o, - command: [ dtrace_prog, '-o', '@OUTPUT@', '-G', '-s', '@INPUT@' ], + command: dtrace_command + [ '-o', '@OUTPUT@', '-G', '-s', '@INPUT@' ], ) qemu_dtrace_gen_stp = custom_target( -- 2.26.2
