How to build

[sweisman]

I hate to ask this question. How do you build these projects? I tried, in the pxlib-and-pxview repo directory:

autoreconf

Which results in a number of errors.

[sweisman@zaphod pxlib-and-pxview]$ autoreconf

Try using the autogen.sh script. I'm building on MacOS; here's an autogen.sh on a fresh git clone:

I think the key difference is that autogen.sh will make the m4 directory for you if it does not already exist.

Did the above answer your question?
