Not able to compile linux code on OVMS 7.3.2

santosh b b — Mon, 12 Apr 2010 12:49:06 GMT

Hi

I am porting an application from linux to OVMS7.3.2 alpha server.

Its a c++ code
I have header files included in the my source file as
#incldue "myInclude/myheader.h"

The cxx compiler errors out saying that "myInclude/myheader.h" not found. But I can see that the file exist there in that location, with permissions set properly.

I have included the paths properly in .mms file.

I am using the mmk utility.

I have also installed the GNV kit. But not of use

Can anyone please help me resolve this issue.

Thanks
Santosh.

1. Please learn how to ask a question. As
usual, showing actual commands with their
actual output can be more helpful than vague
descriptions and interpretations.

> [...] an application [...]

Which "an application"? Is this a secret?

> [...] c++ code [...]

cxx /version

> #incldue "myInclude/myheader.h"

Why are you hiding potentially useful
informatiuon?

> But I can see [...]

I can't. Perhaps you could show us exactly
what you see, and then we all could see it.

> I have included the paths properly in .mms
> file.

I can't see any of that, either. (And if you
knew what "properly" was, then you probably
wouldn't be asking this question here.)

> I am using the mmk utility.

Does that actually matter for this problem?

> Can anyone please help me resolve this
> issue.

(That's a question???)

Perhaps if you include even a little useful
information, like, say, the actual code, the
actual command(s), the actual error message,
and so on, then someone might be able to.

Bad permissions don't return "not found", but rather return the OpenVMS equivalent of a no-permissions error.

GNV is only marginally related, and only if you're building within that environment.

MMK is also only marginally related, save for its use in reproducing the error.

If I've guessed at the question, please take the time to read the CXX user's guide and related parts of the manual and the HELP text:

HELP CXX /INCLUDE_DIRECTORY

My guess here is that the "myinclude" stuff isn't set up or isn't set up correctly, and that's covered in the help and the manuals.

If I've not guessed correctly, please post the versions and a concise reproducer and the compiler diagnostics that are encountered when you build the reproducer.

Also take the time to improve your own career prospects and your value to your project and your manager by reading and learning this:

#incldue "myInclude/myheader.h"

This notation means that this include file should be in OpenVMS logical disk notation.

myInclude:myheader.h

If you not familiar with OpenVMS well,
shortly,
myInclude is a logical name of the path,
myheader.h is a file located in the path.

Example:
your include file myheader.h is located at
dka0:[project.files.myinclude]

you should:
$DEF myInclude dka0:[project.files.myinclude]
Then you may to be sure its ok:
$dir myInclude:myheader.h
The file should be present.

Then you can
#include

No logical needed, but if there is one, it should point to the right directory, except ...

$ def myinclude huhu

$

PS: Translating a logical here is a CRTL feature. The behavior is influenced by the setting of the logical DECC$DISABLE_TO_VMS_LOGNAME_TRANSLATION (although the documentation indicates it isn't).

$ sh log openssl
"OPENSSL" = "DKA100:[SYS0.SYSMGR.SSSU_OVMS.CCB2.INCLUDE.OPENSSL.COMMON.OPENSSL]" (LNM$PROCESS_TABLE)
$

As my header files related to openssl is in that path.

but once i created the logical path and compiled I am getting the below error

For Insufficient Virtual Memory check this first:
