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 ________________________________________ From: [email protected] [[email protected]] On Behalf Of Jorge Fernandez Monteagudo [[email protected]] Sent: Friday, January 29, 2016 7:26 PM To: [email protected] 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!
