Nevermind, I figured it out!

cd into the dir where you downloaded lede-project
$ mkdir package/libs/libugpio/
$ cd package/libs/libugpio/
$ wget https://dev.openwrt.org/export/35269/packages/libs/libugpio/Makefile
$ cd -
$ ./scripts/feeds update -a
$ ./scripts/feeds install libugpio
$ make menuconfig
Select Libraries, go down to 'libugpio' and press 'M'
save changes and exit
then build it:
$ make -j4

Ok, it turns out that I had a typo and it was trying to compile the wrong source file.

However, now I'm getting the error "ugpio/ugpio.h: No such file or directory", which would be caused by the aforementioned problem. How do I get libugpio to show up in "make menuconfig"?

Thanks,

I'm trying to compile a really simple c++ test program to make sure my cross-compiling workflow is setup, and I'm getting the error:

mipsel-openwrt-linux-gcc: error: gpioRead.c: No such file or directory
Makefile:9: recipe for target 'gpioRead' failed

I tried following the instructions from "From "Cross-Compiling for the Omega" I cannot successfully build the gpioRead example", but I was unsuccessful in getting it to work (libugpio wasn't shipped in the onion source repo, and it never showed up in menuconfig, even after adding the Makefile to package/libs/libugpio)

Any help would be greatly appreciated.
