Cross-compiling ocaml apps for ARM

阅读更多关于 Cross-compiling ocaml apps for ARM

I'm cross-compiling a touchscreen driver, which comes with an ocaml calibration application. I'm trying to compile the driver and the application for ARM, in particular, the Beagleboard, running Angström. It goes like this: ^_^[raziel@Bebop zytouch-driver-20081121]$ source /usr/local/angstrom/arm/environment-setup ^_^[raziel@Bebop zytouch-driver-20081121]$ make CC=arm-angstrom-linux-gnueabi-gcc arm-angstrom-linux-gnueabi-gcc -std=gnu99 -g -O2 -Wall -Wextra -Werror -Wstrict-prototypes -Wmissing-prototypes -c -o daemon/config.o daemon/config.c arm-angstrom-linux-gnueabi-gcc -std=gnu99 -g -O2

I can still debug, but I can't debug anything other than the main thread. I have read forums that suggest installing the packages libthread-db1 and glibc-dbg, but this does not correct the problem for me. On my machine I have the 3 files /lib/libthread_db.so.1 , /lib/.debug/libthread_db-1.0.so , and /lib/libthread_db-1.0.so . I tried creating symbolic links in /lib with the
