MHD_start_daemon error when trying to install/build

[GhoulWorlde]

Hi there, I'm on a fresh install of Pop OS 22.04 and I can't seem to run the final command for building in the readme. I've got an 18i20 that is detected by the OS and shows that audio is outputting through the settings and in easyeffects, but there's no audio coming through any of the outputs on the device (I've tried them all) alsamixer shows that it recognizes the device and all its IO, and correctly shows volumes being changed when I turn the knobs, but again, no actual audio coming through. Ive got a 2i2 that works perfectly fine out of the box so I know its not the hardware connected to the devices. The following is the message I receive when trying to build. Any help is appreciated. thx.

Hi, I have a very similar problem to the above. I am trying to install Alsa Jason Gateway on a new Kubuntu 22.04 installation so I can use my Scarlet8i8 with the Alsa Jason Mixer and the latest version of Ardour. I get the exact same compilation errors reported above. The software worked fine on an older Ubuntu distribution (Trusty Tahr). Any help appreciated. Paul
