makefile to generate memory contents in Altera SOPC Builder

[Jeroen]

Hi,

I'm working on a Cyclone FPGA with NIOS project, which contains an onchip
bootrom. I want to use a makefile to generate the contents of this bootrom.
At first I used a single .C file which worked fine, but now I'm using a
makefile and I can't get it to work. Can't find anything about it in the
Altera documentation or website. My makefile is very simple and only
contains one line to nios-build a bunch of C files.
The command I use is "make -f %2/myproject.make" but it terminates with a
strange error.

Anyone any experience with this?

Hi Jeroen.

One subtle "feature" of the GNU compiler is that it treats files with
the extension ".C" (capital 'c') as a C++ file. If you were planning
this to be purely c-language, you'll run into some strange errors.
Try changing the extension from ".C" to ".c" and re-compile.
