Re: Help requested for AIX compilation failure

[Matt_Conway]

Well, with the morning came a little more enthusiasm, so I did a little 
more digging.  It appears the the latest version fo xlC (5.0.2.0) doesn't 
like "-I/usr/include" on the include path.  I'm assuming its because it 
has some other headers elsewhere (in my case, string.h) which it uses to 
override the ones in /usr/include.  I removed the -I/usr/include from 
ddd/Makefile, and everything else compiled ok, except for the following 
problems (do I need to worry about them?):

xlC -DHAVE_CONFIG_H -I. -I. -I. -I./..     -DNDEBUG -g   -c glob.C
"my-alloca.h", line 41.16: 1540-1405 (W) Syntax error in "#pragma alloca": 
expected "(" and found "end-of-line". The pragma is ignored.

These simply need a "-qrtti" on the command line - I don't know autoconf, 
so I'll let someone else add it
xlC -DHAVE_CONFIG_H -I. -I. -I. -I./..     -DNDEBUG -g   -c ddd.C
"ddd.C", line 6943.21: 1540-2411 (W) A dynamic cast is present, but the 
correct RTTI option is not specified.
xlC -DHAVE_CONFIG_H -I. -I. -I. -I./..     -DNDEBUG -g   -c LiterateA.C
"LiterateA.C", line 360.5: 1540-2411 (W) A dynamic cast is present, but 
the correct RTTI option is not specified.
<snip> same error for a number of other c++ files in the ddd directory

xlC -DHAVE_CONFIG_H -I. -I. -I. -I./..     -DNDEBUG -g   -c GraphEdit.C
"GraphEdit.C", line 99.9: 1540-1281 (W) "offsetof" cannot be applied to 
"struct _GraphEditRec".  It is not a POD (plain old data) type.
"GraphEdit.C", line 99.9: 1540-1281 (W) "offsetof" cannot be applied to

Then during make install:

/opt/freeware/bin/install -c -m 644 libiberty.a 
/opt/ddd-3.3.1/lib/libiberty.an
/opt/freeware/bin/install: cannot create regular file 
`/opt/ddd-3.3.1/lib/libiberty.an': A file or directory in the path name 
does not exist.
gmake[1]: *** [install_to_libdir] Error 1

manually creating the directory allowed it to continue.
