It runs on the following platforms: X86/Linux, AMD64/Linux,
ARM/Linux, PPC32/Linux, PPC64/Linux, S390X/Linux, MIPS32/Linux,
MIPS64/Linux, ARM/Android (2.3.x and later), X86/Android (4.0 and
later), X86/Darwin and AMD64/Darwin (Mac OS X 10.7, with limited
support for 10.8).
Please state which are platforms that are supported by glibc and
improtant programs running only on that platform needs mtrace
>From the README:
i[4567]86-*-gnu
i[4567]86-*-linux-gnu, x86_64-*-linux-gnu,
powerpc-*-linux-gnu, powerpc64*-*-linux-gnu, s390-*-linux-gnu,
s390x-*-linux-gnu, sh[34]-*-linux-gnu, sparc*-*-linux-gnu,
sparc64*-*-linux-gnu
aarch64*-*-linux-gnu, alpha*-*-linux-gnu, am33*-*-linux-gnu,
arm-*-linux-gnueabi, hppa-*-linux-gnu, ia64-*-linux-gnu,
m68k-*-linux-gnu, mips-*-linux-gnu, mips64-*-linux-gnu,
tilegx-*-linux-gnu, tilepro-*-linux-gnu
Then there is also *-k*bsd-gnu...
mtrace has its uses, it works, and people use is... Why deprecate a
useful tool?
