Top Forums Programming 64 bit code debugging using gdb and ddd Post 302892009 by biju64 on Monday 10th of March 2014 09:24:33 AM

Thanks for the quick reply Pravin_218.
So I guess I'll have to rebuild both gdb & ddd in 64 bit mode.
Finding it hard to build gdb in 64bit as the code does not seem to be geared towards a 64bit build. Getting errors such as:

aix5ppc-core.c: In function 'xcoff64_core_p':
aix5ppc-core.c:194:13: error: assignment makes integer from pointer without a cast [-Werror]
sec->vma = ldinfo.ldinfo_dataorg;

If anyone has any idea on what to do about such errors please help.

NAME
gzexe - compress executable files in place SYNOPSIS
gzexe name ... DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files: -rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb -rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~ /usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are sure that /usr/bin/gdb works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
gzip(1), znew(1), zmore(1), zcmp(1), zforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail). BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. GZEXE(1)
