Gdb yükleme sembolleri, yüklü bir kitaplığı nasıl oluşturur?

libopal-dbg ve libopal3.10.10 yüklüyor. Ancak hata ayıklama yaparken kütüphane kodunu göremiyorum.Gdb yükleme sembolleri, yüklü bir kitaplığı nasıl oluşturur?

objdump --debugging /usr/lib/libopal.so.3.10.10 verir:

İlginç olduğunu objdump --debugging /usr/lib/debug/usr/lib/libopal.so.3.10.10 çıkışlar hiçbir şey: hiçbir satır numaralarını verir

/usr/lib/debug/usr/lib/libopal.so.3.10.10:  file format elf64-x86-64 

Contents of the .eh_frame section:

Buradan talimatlarını deneyin: http://stackoverflow.com/questions/10000335/how-to-use-debug-version-of-libc – dbrank0

Şaşırtıcı değil: '/usr/lib/libopal.so. 3.10.10 ... /usr/lib/debug//usr/lib/libopal.so.3.10.10...(no hata ayıklama sembollerinin okunması) sembollerinin okunması. (hata ayıklama sembolleri bulunamadı) ... done.' – Velkan

Yani libopal-dbg bozuk görünüyor. Sanırım onu yeniden kurmanız, başka bir yerden almanız veya kendiniz oluşturmanız gerekiyor. – dbrank0

Tamam, şu hack için bu gün işlem gören:

apt-get source libpt-dbg yapın ve yama debian/rules:

Daha sonra paketi debuild -us -uc -i -I ile oluşturun.

Sonraki opal (apt-get source libopal-dbg).
