[srsran-users] Problem building without AVX enabled

[Walter Maguire]

Hi all,

I have been trying to build the code on vsc without the Intel AVX mode instructions.  I would like to run the ldpc code initially without any optimization.

To do this I ran ccmake ../ in the srsRAN/build directory and set the options as shown below.  As can be seen all AVX options have been turned off.

After exiting ccmake, I do

make clean
cmake -DCMAKE_BUILD_TYPE=Debug ../
make
make test
sudo make install




Unfortunately, as can be seen from the vsc screenshot (link below), the LV_HAVE_AVX2 is set.

I would be grateful if anyone would advise me on a fix for this issue.

Regards,
Walter
