Hello,
This is regarding usage of jemalloc, I want to use jemalloc for bare metal
cortex A53 malloc (since bare metal gcc does not support malloc for multicore).
when I use gcc
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/4.6/lto-wrapper
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu/Linaro
4.6.3-1ubuntu5' --with-bugurl=file:///usr/share/doc/gcc-4.6/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr
--program-suffix=-4.6 --enable-shared --enable-linker-build-id
--with-system-zlib --libexecdir=/usr/lib --without-included-gettext
--enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.6
--libdir=/usr/lib --enable-nls --with-sysroot=/ --enable-clocale=gnu
--enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-gnu-unique-object
--enable-plugin --enable-objc-gc --disable-werror --with-arch-32=i686
--with-tune=generic --enable-checking=release --build=x86_64-linux-gnu
--host=x86_64-linux-gnu --target=x86_64-linux-gnu
Thread model: posix
gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) \
Then I can see the make is OK , where as when I use
"bare-4.8.2-3/bin//arm-none-eabi-gcc"
Then I get error
In file included from include/jemalloc/internal/jemalloc_internal.h:5:0,
from src/jemalloc.c:2:
include/jemalloc/internal/jemalloc_internal_decls.h:11:24: fatal error:
sys/mman.h: No such file or directory
# include <sys/mman.h>
^
compilation terminated.
make: *** [src/jemalloc.pic.o] Error 1
Now the problem is since I am working in baremetal I have to use
""bare-4.8.2-3/bin//arm-none-eabi-gcc"
So please let me know if there is any limitation for jemalloc i.e. if it don't
work with bare metal.
Thanks and Regards,
Monika
