How to write(or read) soft IP registers with ARM DS-5?

the Altera GNU-example is not downloaded from Altera websit. It is in the C:\altera\14.0\embedded\examples when the SOC EDS installed.

And I do not touch the Makefie.

Here is the message of warnings.

These "path not found" lines present in console for each source file ?

Good, if no C/C++ warnings, these lines probably from unecessary system variable: need save in Windows console all variables to file ("set > vars.txt") and find there strings as "\usr\include\w32api", think which soft adds these variable, and delete it if possible.

I found 2 good GCC keys from a thousands:

"-E" set compiler mode for preprocess only and output all merged ".c" + "#include" to one .o;

"-H" output to console all# include files with its path for each .c.

These options very usable for debug differences on work/nonwork SoC EDS on various PCs with identical paths of installation.

I search in the vars.txt, and cannot fine strings like "\usr\include\w32api" or anyother "path not found" lines.

And not each source file has these warnings. the "hello world" project does not have.

And I find if the source file has USER CONFIG environment variable,thses warnings occur will appear.

Could you please explain in detail how to add these 2 GCC key in the project？since I am a green hand and I can not understand what you mean to do.

thanks！

Need be to open Makefile for edit and search first word "CFLAGS" with definition.

In these line add "-E", "-H" and any more.

...Entire of PC files may search for "\usr\include\w32api" -- may be through a week any result found! :)

I add "-E" "-H" in the ”CFLAGS“,and when I build the project,error comes out.

and I only add "-H",error not come out.

THE console message is in the console.txt.

linjionghui, you are programmer or student ? Except "Altera Pupil". Need be > independence in thinks !

Console in both cases is different only at bottom: with using "-E" in .o-files not writed compiled object code (compile stage is omitted), and only expanded source with all# includes -- view these files!

Then linker abuses, its unimportant.

These .o-files after -E need be compared with analogous after preprocessing with compiler errors if appears in bad installation of SoC EDS, suddently there is bad# include paths or not same .h-files.

Upper .h-output show used .h-folders and also may be saved and compared with "bad" installation output for analysis.

P.S. Very strang: I view attachment 2 times, and see "console.txt (29.9 KB, 0 views)".
