Ubuntu 16 - problem to install

[caiotelles]

I was following the Installation guide, but when I executed the make I had some issues.

Can anyone help me?

liquid-dsp$ make

Hi,

I believe this is the same issue as #47

[caiotelles]

Sorry brian, you are correct.

Just to document:

1. edit the makefile
2. change the CONFIG_CFLAGS line and add -msse3 (CONFIG_CFLAGS = -g -O2 -msse3)
3. save the file and NOT rerun ./configure
4. run make (now will work 👍 )

Thanks people!!

[brian-armstrong]

Another, probably more stable option, is to apply #65 and rerun autoconf (or bootstrap.sh) which will cause configure to emit the right msse flag into the makefile. Then you won't have to worry about accidentally rerunning configure.

[charlieh0tel]

./configure CFLAGS="-O -msse3"

also works.

2019 Dec, still need the above CFLAGS to compile on Ubuntu 19.04 Lenovo x230.
