Using aC++ A.06.15 compiler version => Identifier "__fpreg" is undefined

[Neel2]

Hello Dennis,

Thanks a ton. The link is really helpfull for porting.

I quickly went thru and found same error described, at ISO-22. No storage class on template specialization (2080)

Where they have suggested to remove the static storage keyword to work on both compilers. It is correct way to solve the my bunch of errors?

OR I should use -W2759 on the command line according to ISO-42.

Best regards,
Neel

This wasn't your problem, error 3449. You didn't have static there.

>OR I should use -W2759 on the command line according to ISO-42.

You don't have that either. (Unfortunately there is a typo, it should be +Ww2759.)

Hi Dennis,

Thanks for your input. So I just want to know, to get rid of error #3449 explicit specialization of member...Is it un-avoidable with aCC6, there is no backward-compatibility? then what should be the best way to resolve the above error?

1.
Can I use some flag(command line)which will take care of the above discussed issue.

2. Do I need to start changing all source code files, ( which is itself huge no. of files) just becuase we have change the compiler version ?

3. What best available options are there to solve the above error ? your suggestions are always welcome.

Best regards,
Neel

Yes, it is unavoidable. This is a bug in the old compiler that's been fixed. That it doesn't check for source layout errors.

>1. Can I use some flag which will take care of the above discussed issue.

There are no flags for this. (I don't remember seeing any customer complaints about it either.)

>2. Do I need to start changing all source code files, just because we have change the compiler version?

Yes, your code is broken and you have to fix it.

>3. What best available options are there to solve the above discussed issue, since you the complete issue?

Your only option is to add those explicit specialization declarations.

Hi Dennis,

Thanks for reply. Today I found that one of my file extn is .c, and the compile log shows that it invoke the cc driver to compile .c file(below).I have set my driver as aCC, and want to compile .c file with aCC only. I do not want to automatically take care by driver, then which flag should I pass from command line to forcefully compile .c file with aCC.

cc -c -D_REENTRANT -mt -g +DD32 +Z -DDEBUG -I.. templates.c -o templates.o

Best regards,
Neel

The -Ae, -AC89 or -AC99 options:
aCC -Ae -c -mt -g +DD32 +Z -DDEBUG -I.. templates.c

Thanks Dennis.

I have one more question regarding the template. I found that +ESnolit needed for compiler/linker workaround for templates at least through ACC 03.33/03.30. And -DOS_ENABLE_MEMBER_TEMPLATE_FEATURES in one of our makefiles, Is it still available with aCC6?

Also, +inst_compiletime flag can be useful for the above discussed issue of template?

Best regards,
Neel

Hi Dennis,

When I used command line flag "-Ae", and looking at verbose it shows that "-D__HP_cc=61500", what does it mean, i found that broke my compilation since we had some check for __HP_aCC which got failed now.

I am looking for a flag which will treat .c file as .cpp and will be compile with aCC.

Best regards,
Neel
