Gruel missing from gnuradio compilation and install

GNU Radio
1

Platform: Motorola Xoom MZ601 armhf.

gnuradio-3.6.3 includes gruel. But compiling gr-osmosdr against 3.6.3
fails.

gr-osmosdr compiles without errors against gnuradio-3.7.0, but this
version of gnuradio does not include gruel. No matter if the
CmakeCache.txt file is edited directly to enable gruel, or the command
line option of -DINSTALL_GR_GRUEL=ON is used, gruel is not included in
the compilation and installation of gnuradio.

Consequently, gr-ais cannot be compiled and installed because gruel is
missing.

Also, gr-ais complains “gr_sync_block.h” cannot be found. It is
possible a naming convention is the problem here because in
/usr/local/include/gnuradio the file “sync_block.h” exists, not
“gr_sync_block.h”

It appears to me the folks at gnuradio have made some changes that
affect one’s ability to install gr-ais. Does the right hand know what
the left hand is doing here?

Looking for solutions to this impasse.

Thanks

I have waited several times well beyond 15 minutes in an attempt to edit
my last post.

Additional information:

OS is Ubuntu Precise for armhf in a chroot environment.

I have tried all version of math.h found in the linux environment, all
file systems. Tons of errors, no matter which math.h version I try.

Also, strangely enough gr-ais is looking for header files in it’s own
sources /include directory which in my case is
/home/android/Downloads4/gr-ais/include.

I have downloaded the latest gnuradio-3.7.1 which also does not include
gruel.

Anyone involved with developing gnuradio that can address this issue?

Has gruel been dropped from gnuradio? Renamed and relocated in the file
heirarchy?

gruel is not available separately for arm or armhf in source or binary
form.

Thanks.

Solution to gruel failure to compile and install - gnuradio-3.7.0 and
probably 3.7.1 follows:

In a text editing program open
/gnuradio-3.7.0/gruel/src/python/gruel/CMakeLists.txt file. Change
“GrPython(include)” to “GrPython.cmake(include)”. Save the file.

Copy “GrPython.cmake” from /gnuradio-3.7.0/cmake/Modules/ to
/gnuradio-3.7.0/gruel/src/python/gruel.

In a text editing program open
/gnuradio-3.7.0/gruel/src/python/gruel/GrPython.cmake
On line 125 change “CmakeParseArguments” to “CmakeParseArguments.cmake”
Save the file.

Copy “CmakeParseArguments.cmake” from /gnuradio-3.7.0/cmake/Modules/ to
/gnuradio-3.7.0/gruel/src/python/gruel

Run cmake, make && make install against
/gnuradio-3.7.0/gruel/src/python/gruel/
