Unable to build srsue and srsenb

[adivh]

Hi,

I am trying to build the 4G project from source with the intention to build a little SDR application and play around with the code.
I have installed the required libraries, cloned the repository, created a build folder and have run cmake as instructed.
I can run sudo srsepc but sudo srsue and sudo srsenb return 'command not found'.

/usr/local/bin/ contains srsepc but not srsue or srsenb, explaining the 'command not found'.

I expected to find the folders build/srsepc, build/srsenb and build/srsue with an executable in each build/*/src; but only build/srsepc exists. Do I need to do something else for the enb and ue to be built as well or did I miss something? :(

I am using a mostly fresh Ubuntu Desktop 22.04 LTS installation with kernel version 6.5.0-25-generic x86_64.

What I tried:

• I am not too familiar with cmake but I checked ./CMakeLists.txt and ENABLE_SRSUE, ENABLE_SRSENB and ENABLE_SRSEPC are all set to ON.
• Then I thought, that I have no RF drivers installed and maybe cmake noticed and omitted building srsue and srsenb. So I installed limesuite, ran cmake and make again, but there are still no srsue and srsenb.
• I tested installing the packages from the ppa and this worked, but I would like to build from the source.

The problem was in fact the missing RF drivers. Installing soapysdr-module-lms7 instead of limesuite fixed the issue.
