I'm trying to compile an ada program, using gcc 4.3. I has a pragma Linker_Option("-laddr2line"); Now, I thought that binutils would provide that, but no. It does provide the _program_ addr2line but not the lib. gnatbind -aO./ -E -I- -x /Users/bnl/programming/svn_base/cl/moses/ sattmate/target/adalib/global/stingray/sattmate_config.ali gnatlink /Users/bnl/programming/svn_base/cl/moses/sattmate/target/ adalib/global/stingray/sattmate_config.ali -g /usr/bin/ld: can't locate file for: -laddr2line collect2: ld returned 1 exit status gnatlink: cannot call /usr/local/gnat/ada-4.3/bin/gcc gnatmake: *** link failed. suggestions of where to get the lib? /Björn Björn Lundin b dot f dot lundin at gmail dot com
