1.5.2 on OS X, ppremake aclocal error

Installation
1

I’m trying to follow the Edalytical tutorial (http://www.edalytical.com/articles/building_panda3d_on_mac_os_x_leopard.html) on OS X 10.5.4 with Panda 1.5.2 (leaving out the patches, for now), but I run into trouble building ppremake. On the aclocal step, I get the following error:

acinclude.m4:1: warning: underquoted definition of AC_HEADER_IOSTREAM
acinclude.m4:1:   run info '(automake)Extending aclocal'
acinclude.m4:1:   or see http://sources.redhat.com/automake/automake.html#Extending-aclocal

I’ve successfully followed the rest of the steps up through running genPyCode by following Hypnos advice (https://discourse.panda3d.org/viewtopic.php?t=4468), but when I run genPyCode I receve the following error:

$ genPyCode

My fftCompressor.cxx and Config.pp look the way Hypnos suggests in the thread I linked above above.

Any thoughts?

Right, the error message you are getting is because you need to link to another library. It is explained on the comments of the guide.
Scroll down to the bottom of the page and you will find:

PS. Also, the guide is missing a step. Before running genPyCode, you also need to cd into the pandatool directory and make && make install it.

Okay, I completely deleted and remade Panda from scratch following your instructions, including building and installing pandatool. My genPyCode output looks like this:

However, when I try “>>> import direct.directbase.DirectStart” as per the bottom of the Edalytical tutorial, or run any of the sample code:

Your Config.prc file must name at least one valid panda display
library via load-display or aux-display.

I have a 20_panda.prc in my /usr/local/panda dir, but no Config.prc…

You need to create a Config.prc and put the plugin-path definition in it. This should name the directory that contains libpandagl.so and whatnot.

Okay, one step further along. Thank you drwr!

I ended up fixing a few other config-related problems that appeared when I tried to run the samples. In case anyone hits this batch of problems again, here’s the current contents of my Config.prc file, which makes the samples I’ve tried (from ./panda3d-1.5.2/samples/) work in OS X:

plugin-path /usr/local/panda/lib
default-model-extension .egg.pz
model-path .
