How to generate different ELF files at once in IDE

[Altera_Forum]

Hello, 

 I have two projects (for our customers) which have the same Nios II IDE project as a source code basis. These two projects are mainly the same, only a few# define values are different when I build the IDE project.  How can I build both projects from my IDE project at once and automatically? I would like to have two ELF files output by the IDE, with different names or in different folders for each customer project.  I hope there is a way to do this.   If the IDE does not offer such flexibility, how can I create easily (if not automatically) a makefile or similar to generate the two versions by DOS command line?

I see two possibilities in this case: 

 - (DOS-based) if you are using a simple HAL project, just create two configurations from the properties of the project; that will generate a makefile in two separate directories (call them Product1 and Product2 instead of Debug/Release). Then, just write a batch file to call make -s on the 2 directories form the command line. You can differentiate among the two products using a -D option passed to the gcc.  - (Eclipse based) If you want to remain eclipse based to also control the generation of the makefiles, you can use an ANT script to prepare a little sequence of actions to be performed that are typically a mimic of the commands that can be issued from the IDE. (ANT also works from the command line). That is for example the typical thing we do when I want to generate and compile different application configurations from an OIL configuration file when using ERIKA Enterprise. However, I do not know if the Altera support ANT scripting...  bye  Paolo

Hi Paolo! 

 Thank you very much for your answer, I decided to implement the DOS batchfile. After various problems finding the right PATH settings, it finally worked out for me.   For everyone who is interested in the paths:  I got the "make" command from %QUARTUS_ROOTDIR%\bin\cygwin\bin\make  ...and called it with the "-s all" or "-s rebuild" options.  To work correclty, at least the following three directories have to be in the search-path:  %QUARTUS_ROOTDIR%\bin\cygwin\bin %SOPC_KIT_NIOS2%\bin\nios2-gnutools\H-i686-pc-cygwin\bin %SOPC_KIT_NIOS2%\bin
