Hi,

We've upgraded from the Visual Age version 6 compiler to XLC/C++ 8.
The compiler works ok when all source is in the same directory and the
-I option is not specified. Once using the -I option I get errors such
as those below regardless of whether using the C (xlc) or C++ (xlC)
compiler. We didn't encounter such errors with VA 6, so any help is
much appreciated.

Stop.

The compiler config file looks ok to me. Here are the settings for the
C and C++ compiler for reference:

* -qlanglvl=extc89 C compiler with common extensions, UNIX headers
xlc: use = DEFLT
crt = /lib/crt0.o
mcrt = /lib/mcrt0.o
gcrt = /lib/gcrt0.o
libraries = -L/usr/vac/lib,-lxlopt,-lc
proflibs = -L/lib/profiled,-L/usr/lib/profiled
options = -qlanglvl=extc89,-qcpluscmt,-qkeyword=inline,-
qalias=ansi


* C++ compiler
xlc++: use = DEFLT
crt = /lib/crt0.o
mcrt = /lib/mcrt0.o
gcrt = /lib/gcrt0.o
xlC = /usr/vacpp/bin/xlC
libraries2 = -L/usr/vac/lib,-lxlopt,-L/usr/vacpp/lib,-lC,-lm,-
lc
proflibs = -L/usr/vacpp/lib/profiled,-L/lib/profiled,-L/usr/
lib/profiled
hdlibs = -L/usr/vac/lib,-lhC,-lhmd
options = -qalias=ansi

* C++ compiler
xlC: use = DEFLT

gcrt = /lib/gcrt0.o
xlC = /usr/vacpp/bin/xlC

This may be a long shot, but I suspect VAC is expecting C99-compliant
includes, and depending on the version of AIX you're using, you may not
have C99-compliant includes. I've seen this a lot between AIX and Solaris,
especially older releases of each respective operating system. Try kicking
VAC into a non-C99 mode (C89, etc.).

Hi Derek,

Thanks for the reply. I don't think this is the problem though. I
modified the compiler options from

xlc -c decNumber.c -I../include

which causes the above errors, to the following which works fine

xlc -c decNumber.c -I/usr/include -I/usr/vac/include -I../include

Why would the 2nd command work but the 1st not. My understanding is
that the compiler should have a default system include path.

Anyway, this is related to C compilation. Moving on to C++. I tried
adding the include paths for C++ code but still the same problems. I
tried all invocations or aliases of the compiler, those you mentioned
and everything else in the bin directory but still no go. I'm
currently looking at the compiler options, but cannot see anything
that I need to change. As I previously stated, the default compiler
configuration file looks ok, but I may be wrong.

Regards,

Michael

A possible cause of this type of problem is that the ../include
directory has a file named stdint.h that does not contain
declarations that /usr/include/sys/inttype.h uses.

If there is a ../include/stdint.h file, temporarily remove it and
compile decNumber.c to see if it uses declarations made in
.../include/stdint.h that are not made in the now standard
/usr/include/stdint.h. At best, the now standard stdint.h
will have all the declarations and you can erase ../include/stdint.h.

At worst, you can rename ../include/stdint.h, modify it to not
duplicate declarations in the standard stdint.h, and and change the
#includes of it to use the new name.

Excellent, you are correct and this worked.
