were you able to compile gr-lte in gnuradio 3.7.9?
Yes. I delete gr-lte manually and re-compiled after re-clone. The error is disappear... It's strange!
But you posted no module lte_swig how did you compile it without the module?
Yes, I compiled gr-lte successfully and no error occurred. The error was occurred when I ran the gnuradio-companion. I follow the steps strictly.
Get gr-lte from github
Configure it using CMake
Assuming you are already in the project folder
mkdir build
cp cmake_command.sh build/
cd build
./cmake_command.sh
This will just run a little script to aid with project setup for Code::Blocks
Otherwise runcmake ..
Compile and Install
make -jX
where X is a number of choice (Often the number of cores available)
sudo make install
(make it available in GRC)
Did you fail to compiled due to the module?
What version gnuradio did you use? I am currently using 3.7.9 in linux mint.
YES! I used ubuntu 16.04, the version of gnuradio is 3.7.9. What error is you met?

It comes up with error: expected token in front of 'char'.
Linux mint version i have is 16.04 in ubuntu because it uses the same mirrors. If you have gnuradio-core module file can you send that to me. I haven't had any luck downloading it from any source and its not available on apt nor pybombs. I even tried python and nothing has it.

Hi @Keskebeu,
/usr/src/gr-lte/lib/crc_check_vbvb_impl.cc:89:39: error: ‘__GR_VLA’ was not declared in this scope __GR_VLA(char, bytes, d_data_len / 8);
The __GR_VLA macro was added in gnuradio v3.7.9.3 which is still not available in Ubuntu 16.04 / Mint 18.02. If you add it in include/lte/api.h
it should compiles

@Velichkov Thank you for your research and help. I knew it was incompability either gnu or linux. But I will include this file in my lte when i get home and will let you know.
Thank you again.
@velichkov thank you so much for the patch. I was able to compile, import lte and test it. Now time to have some fun.
This issue should now be closed
Thanks a lot! @velichkov
As the Title says, I ran the gnuradio-companion lte_bch_decoder.grc, the error ocurred. The branch I use is cmake-volk-fix, the version of gnuradio is 3.7.9.
