Another one...
I don't know why the autogen.sh is getting the properties from the building
system not the target???
I do
$ source
/opt/fsl-imx-fb/3.14.52-1.1.0/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
$ ./autogen.sh --build=x86_64-linux --host=arm-poky-linux-gnueabi
--target=arm-poky-linux-gnueabi --enable-debug
...
checking whether byte ordering is bigendian... (cached) no
checking size of void *... (cached) 8
checking size of int... (cached) 4
checking size of long... (cached) 8
checking size of intmax_t... 8
checking build system type... x86_64-pc-linux-gnu
checking host system type... arm-poky-linux-gnueabi
...
with this defines the code generated is wrong. The void * is a 32b pointer in
the target, but a 64b one in the build machine.
There are some warnings compiling too
arm-poky-linux-gnueabi-gcc -march=armv7-a -mfloat-abi=hard -mfpu=neon

Subject: RE: jemalloc on iMX6 ARM
Another clue. I've generated the library with
$ ./configure --build=x86_64-linux --host=arm-poky-linux-gnueabi --enable-debug
and now I have
# export LD_PRELOAD=/tmp/libjemalloc.so.2
# ls
<jemalloc>: src/rtree.c:18: Failed assertion: "bits > 0 && bits <=
(sizeof(uintptr_t) << 3)"
Aborted

Subject: jemalloc on iMX6 ARM
Hi all, this is my first post to this mailing list.
I'm trying to give a try to jemalloc in a iMX6 ARM board. I've
downloaded the current master image from
https://github.com/jemalloc/jemalloc/tree/master
I've done the cross compilation with no problem and I've deploy
the lib to the board. Our iMX6 image is using 3.14 linux kernel.
The library generated with
./configure --build=x86_64-linux --host=arm-poky-linux-gnueabi
scp lib/libjemalloc.so.2 root@<imx6_board_ip>:/tmp/
when I tried in the board I get:
# export LD_PRELOAD=/tmp/libjemalloc.so.2
# ls
Bus error
and in dmesg I can see
Alignment trap: not handling instruction e1b14f9f at [<76f06b14>]
Unhandled fault: alignment exception (0x011) at 0x76f2cfe4
If I build the library with
./configure --build=x86_64-linux --host=arm-poky-linux-gnueabi --disable-fill
scp lib/libjemalloc.so.2 root@<imx6_board_ip>:/tmp/
when I tried in the board I get:
# export LD_PRELOAD=/tmp/libjemalloc.so.2
# ls
Segmentation fault
I guess the jemalloc is able to work on ARM systems. Where should I start
looking to
make it work? Any hint is welcome!
Pd: This is the configuration the 'configure' process prints on screen
