Has anyone had any luck compiling the latest 3.7.8 on cygwin? I’m  
running  
into the following:

[14%] Built target pygen\_python\_volk\_modtool\_95e3e  
[14%] Built target pmt\_generated  
[15%] Built target gnuradio-pmt  
Scanning dependencies of target gnuradio-runtime  
[15%] Building CXX object

/home/matt/src/gnuradio-3.7.8/gnuradio-runtime/lib/thread/thread.cc:245:23:  
fatal error: sys/prctl.h: No such file or directory  
#include \<sys/prctl.h\>  
^  
compilation terminated.

I don’t believe sys/prctl.h exists in cygwin (or even all flavors of  
unix). Am I missing something obvious?

I got it compiled (if anyone is interested) with the attached rough  
patch.  
Here are the steps I took:

# compile latest Cheetah

wget  
[https://pypi.python.org/packages/source/C/Cheetah/Cheetah-2.4.4.tar.gz](https://pypi.python.org/packages/source/C/Cheetah/Cheetah-2.4.4.tar.gz)  
tar -zxf Cheetah-2.4.4.tar.gz  
cd Cheetah-2.4.4  
python setup.py build  
python setup.py install

# compile gnuradio

GNUR=gnuradio-3.7.8  
wget [http://gnuradio.org/releases/gnuradio/$GNUR.tar.gz](http://gnuradio.org/releases/gnuradio/$GNUR.tar.gz)  
tar -zxf $GNUR.tar.gz

# apply patch

[-d $GNUR/build] || mkdir $GNUR/build  
cd $GNUR/build
