From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thierry Bultel Date: Wed, 19 Sep 2012 17:44:06 +0200 Subject: [Buildroot] thread debugging with target gdb Message-ID: <5059E846.8070000@basystemes.fr> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Hi, I am using buildroot 2012.08 , configured for ARM cortex A9, crosstools and glibc-2.11. The glibc has been built with 2.6.38.8 headers, my running kernel is 3.2.21, in qemu for versatile express. The issue is that thread debugging does not work, first because /lib/libthread_db.so.1 was not pushed on the 'target' directory I 'solved' this by adding it: CTNG_LIBS_LIB := ld*.so libc.so libcrypt.so libdl.so libgcc_s.so libm.so \ libnsl.so libpthread.so libresolv.so librt.so libutil.so \ libthread_db.so ... in crosstools-ng.mk but is is maybe not the right way. I have activated some debug log in gdb, and I am falling into those issues. Reading symbols from /root/ihm...done. (gdb) r Starting program: /root/ihm Trying host libthread_db library: libthread_db.so.1. Host libthread_db.so.1 resolved to: /lib/libthread_db.so.1. td_ta_new failed: application not linked with libthread thread_db_load_search returning 0 Trying host libthread_db library: libthread_db.so.1. Host libthread_db.so.1 resolved to: /lib/libthread_db.so.1. td_ta_new failed: application not linked with libthread Trying host libthread_db library: /lib/libthread_db.so.1. td_ta_new failed: application not linked with libthread thread_db_load_search returning 0 warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available. Error: Can't open display: [Inferior 1 (process 612) exited with code 01] Thus the "td_ta_new" symbol is found but the call fails Any clues or hints ?
