Try using wxWidgets_CONFIG_EXECUTABLE=/path/to/wx-config instead of

I cannot get it to work either.


You could try temporarily removing you libwxgtk2.8-dev (Debian based
distros) package so the CMake will only be able find your custom
wxWidgets build.  This is what I thought I fixed by adding
NO_DEFAULT_PATH to the CMake find_file() command.  I will try to
duplicate this over the weekend and see if I can figure out why CMake is
having issues.  I will need to know what version of CMake you are using.
First,I put /home/jfm/wx/bin at the front of my PATH so wx-config could be executed. 

$ wx-config --libs
-L/home/jfm/wx/lib -pthread -lwx_gtk2u_xrc-3.0 -lwx_gtk2u_html-3.0 -lwx_gtk2u_qa-3.0 -lwx_gtk2u_adv-3.0 -lwx_gtk2u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0
Then I put /home/jfm/wx/lib on my LD_LIBRARY_PATH, but probably not necessary because of the -L flag in the output above. 


Then I  executed the minimal flags necessary to cmake to succeed

This is the same error I get with using wxWidgets_ROOT_DIR instead or even with simply issuing the command 

cmake .


I am using the system cmake, version 2.8.12.2
Fedora 20
kernel 3.16.3
g++ 4.8.3
I'll try moving libwxgtk2.8-devel out of the way so I can generate some makefiles and build kicad.

Wayne,

I tried at r5159 and got  exactly the same errors as I wrote about below.

Is it possible to have wxWidgets somewhere in the HOME directory tree?
If so,  is cmake . -DwxWidgets_ROOT_DIR=/home/jfm/wx ...
the right command to use on Linux to find my compiled wxWidgets?

I wish I knew more about the kicad cmake system than I do.
Every other thing I have tried leads to the same result.  On the other
hand, I know  a lot more about the cmake system than I did.

well, I  took the advice offered and added the wxWidgets bin directory

This is the error I have been struggling against.  Notice the complaint
about  2.8 and 3.0.   That is,  the argument to cmake was pointless.
But also notice it did find wxWidgets at ~/wx.   It then corrupted the
output to look like it was meant for Windows, not Linux.  Linux would
throw up on such drivel.   wx-config --libs gives what I would expect

/home/jfm/wx/bin/wx-config --libs
-L/home/jfm/wx/lib -pthread   -lwx_gtk2u_xrc-3.0 -lwx_gtk2u_html-3.0
-lwx_gtk2u_qa-3.0 -lwx_gtk2u_adv-3.0 -lwx_gtk2u_core-3.0
-lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0

That, at least, looks good to me.


so next I tried

cmake . -DwxWidgets_ROOT_DIR=/home/jfm/wx

but that gives exactly the same error as the previous error.

Finally I tried just this

cmake  .

expecting that to fail, and it did but it gave me the same error as all
the rest of these attempts.

So I am out of possibilities that Google gave me.

How does anybody run cmake with wxWidgets not in /usr/local nor in the
system dirs?

There was a bug in the wx/version.h search paths which I believe is
causing this problem.  I just committed the fix in r5159.  Please see if
this fixes your problem.

Thanks,

Wayne

I have very recently built a new  64-bit linux system, with a new GPU.
Of course, I wanted to build kicad on this new system.
I have installed cuda and built wxWidgets 3.0.1  and I really look
forward to to running the push-and-shove router.

But I never make it past  the wxWidgets test in cmake.
My system has wxWidget 2.8.12-9 installed and I get the complaint that
3.0 is required.
I built wxWigets 3.01 and installed it in $(HOME)/wx and used the flag
-DwxWidgets_ROOT_DIR=$(HOME)/wx with cmake.   I thought this would
work but it does not and fails on the same complaint about finding 2.8
and requiring 3.0 (or better), but it also says that it found my
$(HOME)/wx  wxWidgets.

That is, it fails on the version complaint first and then finds  the
wxWidgets 3.0.1 in $(HOME)/wx, or it seems to fail first and then find
newer wxWidgets but cmake fails overall.

The system cmake version is 2.8.12.2.
g++  4.8.3
kernel 3.16.3

I am not very  familiar with kicad cmake.  Is there some trick others
have found to accomplish building  with wxWidgets not in either
/usr/local nor installed in the system paths?
