Re: [Discuss-gnuradio] OSX gnuradio/uhd issue

[update lee]

Oh darn, way to much multitasking, thats my mistake. I did have that issue, when I deleted the folder and had git recreate it I forgot to checkout the next branch. I recognized I did this and resolved the issue. Thats when I get a new error, I must have flipped between to many windows and C&P'd the wrong error msg

the error Im getting with the next branch, confirmed with the link you provided
