I have an ARM development board based around freescale’s iMX6q ARM Cortex A9 processor. I also have an application that I want to debug on the board. The dev board is running a running a LTIB filesystem with non stripped runtime libraries. On the host I have downloaded a Linaro toolchain as well (the soft float 2012.04 to be specific) which has only stripped libraries.<\/p>\n

I would like to tell gdb (running on the host) to use a different set of runtime libraries (non stripped ones), from the image of the LTIB filesystem I keep on the host.<\/p>\n

How do I do that?<\/p>\n

asking gdb to give me<\/p>\n

(gdb) show debug-file-directory\n<\/code><\/pre>\n
it returns some path that doesn’t even exist on my host filesystem….<\/p>\n
The directory where separate debug symbols are searched for is \n\"\/cbuild\/slaves\/oort14\/crosstool-ng\/builds\/arm-linux-gnueabi-linux\/install\/lib\/debug\".\n<\/code><\/pre>\n
and I am not even certain this is the right variable to tweak..<\/p>\n
update: even set debug-file-directory doesn’t help, the runtime libs used are still in the toolchain path:<\/p>\n
Reading symbols from \/mnt\/nfs_host\/Linaro\/gcc-linaro-arm-linux-gnueabi-2012.04-20120426_linux\/arm-linux-gnueabi\/libc\/lib\/ld-linux.so.3...(no debugging symbols found)...done.\n<\/code><\/pre>\n
