Installing SDCC on Windows
If you have a USRP, you will need the Small Device C Compiler (SDCC) in order
to build the firmware. (If you don't have a USRP, you can skip this step.) The
SDCC is available as a self-installing binary package for Windows. To install
sdcc-2.9.0-setup.exe (2.9.0 under sdcc-win32) from
to a directory of your choice.
(2) Run (3) Log into the account you will use to build GNU Radio (if you are
already logged into that account, log out and log in again). Enter the
sdcc-2.9.0-setup.exe. You must have administrator
privileges; it is easiest if you use the same account you will use to build GNU

If the path to
sdcc is displayed, you are done. Otherwise
you need to add the path to
sdcc to your
You can do this in your

bash shell) or by adding it to your
Windows path. The command you need to add to your

if you are using Cygwin and
$ PATH="$PATH:/c/Program Files/SDCC/bin"
if you are using MSYS (assuming that you installed SDCC in
C:\Program Files\SDCC). To add
sdcc to your Windows
path: * open the Windows control panel: * go to Performance and Maintenance
-> System to get the "System Properties" window * click the "Advanced" tab
and click "Environment Variables" * select "Path" in the top pane and click
"Edit" * add
C:/Program Files/SDCC/bin to the end of the variable
value; if there is already something there, separate the new text from the old
with ";" * click "OK" in the "Edit Variable", "Environment Variables", and
"System Properties" windows * log out and log back in again
Whichever way you
use to set your
PATH, you should start a new command window and
which sdcc command to be sure that SDCC is found.
VPATH builds and make distcheck
on CygwinWindows SDCC as
installed above will not work for
VPATH builds (i.e.,
configure run from another directory) or
distcheck because Cygwin symbolic links are not recognized by the Windows
version of SDCC. If you want to do a
VPATH build or
distcheck you can do one of the following:
- Build and install a Cygwin version of SDCC from source; this is
straightforward (configure; make; make install); you will need the Cygwin flex
and bison packages.
- Add scripts for the SDCC components to check for symbolic links (e.g., with
readlink) and substitute copies of the target files (not tried, but
- Modify usrp/firmware/src/usrp2/Makefile.am to change "
$(LN_S)" to "
cp -p" in the
