Hello. I am currently trying to figure out why my system cannot run 32bit c++ executables (except, perhaps, static ones) To accomplish that, I tried to run a simple hello word c++ program in gdb, as it was suggested here many months ago to fix another problem. However, when I run: "LD_LIBRARY_PATH=/media/34GB/Arquivos-de-Programas-Linux/Gcc-4.9.4/lib32/ gdb ./test" I receive a "Dwarf Error: wrong version in compilation unit header (is 4, should be 2)" Looking for a fix, I tried to add a "-gdwarf-2" to my compilation command, which became: "g++ -m32 -gdwarf-2 -o test test.cpp -Wl,--dynamic-link=/usr/lib32/ld-2.17.so" However, running the resulting binary under gdb, still generated the same error: Executing: "readelf --debug-dump=info binary_name | grep -A 2 'Compilation Unit @'" shows that there still exists two compilation units with dwarf 4. In fact, the gdwarf parameter didn't change anything. There were such two compilation units with before using -gdwarf2 and they are still remain there after using such option. There are also these messages: readelf: Warning: CU at offset 7d contains corrupt or unsupported version number: 4. readelf: Warning: CU at offset 210 contains corrupt or unsupported version number: 4. So, I need a way to make the final binary file to have all its CUs with the same dwarf version. Since the gdwarf parameter failed to force dwarf 2 use across all of them, the only option I can think of is to build a new gdb that would support dwarf4. If there is another way, I am all hears.
