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.
