Dears,

I have created the a C++ function to convert from hexa-decimal to decimal, compiled and used this function as an external routine in Transformer in Linux environment without any issue.

But when i tried to do the same on an Windows 2008 R2 Enterprise edition, compiled the .cpp file using : APT_COMPILER APT_COMPILEOPT fileName APT_LINKER APT_LINKOPT

(/D APT_USE_ANSI_IOSTREAMS /D _WIN32 /D _MBCS /nologo /W3 /WX- /Gm- /EHa /MD /GS- /fp:precise /Zc:wchar_t- /Zc:forScope /Gd /TP /Zi /Oy- /c C:\test.cpp /link /INCREMENTAL:NO /NOLOGO /DLL /DEBUG /SUBSYSTEM:CONSOLE /DYNAMICBASE:NO /MACHINE:X86)

it compiled successfully, then i have created the External Routine using the output file from the compilation step.

when i used the routine in a transformer it fails to compile the job and raises the following error :

Output from transformer compilation follows:

Kindly share your thoughts.

Thanks in advance.

Does the folder in which the library/object exists appear in the PATH when this job is executed? (Check the entry in the job log that contains environment variable values.)

Hi sohasaid,

Did The issue get resolved? if yes how Please share the solution .

Hi ray,

I am facing similar issue as the job is not getting compiled there is no entry in the directory. how can i find out whether the path exists and if it does not where do I add it.

Appreciate your time.
