Hello,

I've tried to build my "test" project based on "cmake".
During this a lot of the cmake stuff was build also.

After that I tried to build the package "wt".
Now I got totally different messages compared to the first run!
These messages were much more helpful for me (the builder was complaining about missing boost libraries).

After adapting the configuration for "boost" and re-building "boost" now I can build "wt" also!!!

It seems, that you have to make a few "cycles" or "iterations" in order to build a package based on "cmake" ....

Betreff: PTXdist: New cmake package (webtoolkit wt)

Hello,

I'm using "ptxdist-2013.01.0" for building a root filesystem.

Now I'm going to bring a new package into my BSP project.
This package is a "C++ Web Toolkit" ("wt", http://www.webtoolkit.eu/wt/download).
You have to use "cmake" in order to build this package; I'm using "cmake-2.8.2".

I created new rules for that package with ptxdist newpackage target But these rules a based on "autotools" rather than on "cmake".

So I created a new package with
ptxdist newpackage src-cmake-prog
in order to see the build steps for a project based on "cmake".

I have adapted my rule file "wt.make":
.
# ----------------------------------------------------------------------------
# Prepare
# ----------------------------------------------------------------------------

#CMAKE_PROG_CONF_ENV := $(CROSS_ENV)

#
# cmake
#
CMAKE_PROG_CONF_TOOL := cmake
#CMAKE_PROG_CONF_OPT := $(CROSS_CMAKE_USR) .

Unfortunately I got a lot of error messages:

user1@GInsPTXdist:~/PTXdist/bsp-gins-qreader$ ptxdist prepare wt

------------------
target: wt.prepare
------------------

What should I do?
Is there an application note for a packages based on "cmake"?

Thanks for any tips!

Best regards,
Jan-Marc.
