Source file path recorded in object code

[Wonsik_Kim]

Hi,

I am building a dll file with OpenMP directives to parallelize the code. I examined the dll file and found my source file path reside in the dll file as follows:

104B1190: 94 11 4B 10 3B 44 3A 5C 50 72 6F 6A 65 63 74 73 ..K.;D:\\Projects

So the question is, how can I remove this information from my dll file? It seems that the numbers at the end of the string is related to OpenMP parallelized portion of the code.

Thanks in advance,

Wonsik.

Can you trydisabling this flag (i.e put the dash at the end):

/Qparallel-source-info[-]
enable(DEFAULT)/disable the emission of source location information
for parallel code generation with OpenMP and auto-parallelization

Thank you for the suggestion. I tried setting the option and the compiler emits the following warning, and the result seems to be unchanged.

1>Compiling with Intel C++ 11.1.065 [IA-32]... (Intel C++ Environment)
1>warning #13000: could not open message catalog file:
1>icl: command line warning #10156: ignoring option '/Qparallel'; no argument required

My compiler options is as folows:

/c /Ob2 /Oi /Ot /Qip /GA /I "include" /I "C:\Program Files\Intel\IPP\6.1.6.056\ia32\..\ia32\include" /I "..\..\core\umc\include" /I "..\..\core\vm\include" /I "..\..\core\vm_plus\include" /I "..\..\codec\common\include" /I "..\..\codec\color_space_converter\include" /D "WIN32" /D "NDEBUG" /D "_LIB" /D "_MBCS" /EHa /MT /GS- /arch:IA32 /fp:fast /Fo"..\..\_bin\Win32\Release\h264_enc_opt/" /W4 /nologo /Qopenmp /Quse-intel-optimized-headers /Qparallel-source-info- /QaxSSE2,SSE3,SSSE3,SSE4.1,SSE4.2

Any suggestions on turning on/off certain options to get it work?

Thanks,
Wonsik.

ps. I am building my application on Visual Studio 2008 IDE.

This is because of the /Qopenmp option.

This is a known issue and is recorded as DPD200119058. It is not fixed. When there is a fix, we will post a news here.

thanks,

Wonsik,

Look in the MS linker options. There may be an option to strip "comments" from the execuitable/dll.
If the above is in a comment section, then it will strip, if not, then it is stuck in there.

Plan B would be to write a utility to search the DLL for offending textand overstrike the text with something to obscure the information. However, read your software license(s) for restrictions against such modifications.

The information is placed there for convenience in profiling. If you are concerned about others finding your source code, you might set up a build procedure which compiles in a temporary location, then removes it. Your security barriers must not be high if this information would facilitate such a search.

[Wonsik_Kim]

Well, if it's a not-yet-fixed issue of the compiler, I guess I would just wait until the issue is fixed. Thank you everyone!

I do not see any path info being included in the final .exe any more with 15.0, but the symbol "_main" is in the .exe though.

But if adding "/Qparallel-source-info-", the symbol "_main" is not emitted as well.

I only tried with simple test cases, please check it out and let me know if it works for you using the option above.

Thanks,

Jennifer
