Fatal compilation error: Out of memory asking for 54091784

[Karthikeya_J_Intel]

I was trying to compile exiting project with Intel® C++ Compiler XE 12.1.5.344 [IA-32] in visual studio 2005 in windows XP operating system. Earlier we were able to compile easily with vs2005 compiler and were using it for long time. With intel compiler, I was able to compile successfully in "debug" mode but not in "release" mode. Even in debug mode with "O2" optimization, it is not compiling. It gave me the following "out of memory" error.1>Compiling with Intel® C++ Compiler XE 12.1.5.344 [IA-32]...

You may be running out of memory as a result of using parallel compilation option on 32-bit system.  Besides trying with that option removed,  I would ask if you use /3GB boot switch, and why you don't go to 64-bit OS if your application is at all large.

Thanks for the quick reply. 

I tired removing parallel compilation option and introduced /3GB switch. Even then compiling in debug model with O2 optimization is not successful. This time it asked for  120393736 bytes.

Error obtained is

1>------ Rebuild All started: Project: ,  Configuration: Debug Win32 ------

Upgrading to 64-bit OS is not possible for us right now.

Project has single autogenerated .h and .cpp. .Cpp has total 6300 lines and this project linked with various dlls. Is there any other workaround?

[TimP]

Disabling interprocedural optimization (/Qip-) or splitting the source file should reduce memory and time consumption during compile.  There are several options documented along that line (/Qinline-max-.....).

>>...Project has single autogenerated .h and .cpp. .Cpp has total 6300 lines and this project linked with various dlls... 6300 code lines in the cpp file is not a big number. However, it is not clear how many lines are in autogenerated header file. >>Is there any other workaround? A root cause of the problem is not known and I really don't know what workarounds could be suggested when nothing is clear. I would do the following: - Comment everything and it applies to ALL h and cpp files in the project. Your main cpp file should look like: [ Main.cpp ] #include "AutoGenetated.h" void main( void ) { /* ...Your functionality */ } Your autogenerated header file should look like: [ AutoGenerated.h ] //...some declarations 1... //...some declarations 2... //...some declarations 3... //...etc... - For Debug configuration disable all optimizations - Undefine ALL defines - Re-Build the project - If the error is not displayed this is your Reference Build for the Debug configuration - Start restoring state of all components you've affected one at a time with mandatory Re-Building the project.
