Linux: compile of GG after OGRE and OGRE not found

[RgnadKzin]

My trees in /usr/local/src/ look like this:

- freealut/
- - freealut-1.1.0/
- freeorion/
- - FreeOrion/
- - - GG/
- ogre/
- - ogre_src_v1-7-1/
- openal/
- - openal-soft-1.12.854/

I added /usr/local/lib to /etc/ld.so.conf.d/usrlib.conf
(that's where it appears to belong, as /etc/ld.so.conf contains an include of the /etc/ld.so.conf.d/*.conf items

I compiiled openal, then freealut, then ogre
after each, I did

sudo ldconfig

, which updates the load configuration, I presume.
I have attached the ogre make install
Everything appears to be OK, stuff gets installed to
/usr/local/include/OGRE/ and /usr/local/lib/OGRE/

Then I go to the /usr/local/src/freeorion/FreeOrion/GG/ directory and cmake:

[Sat Oct 16 - 08:54:47 /usr/local/src/freeorion/FreeOrion/GG]
[bradbva@localhost GG]$ sudo cmake .

I am not worried about the IOS and Doxygen as they appear to be optional.

gcc and g++ versions are 4.4.1
I am on kernel 2.6.32.12
pcLinuxOS
KDE 4.5.2

What am I missing?

[OndrejR]

you did

sudo cmake .

which uses root environment. But for security reasons, this environment is not powerful as normal user. You have to change rights of GG back to normal users(because sudo cmake . generates files which owns root) and run again as normal user

cmake .

as wiki tells.

Ogre OIS is optional for GG, but not for FreeOrion(but if you compiled OGRE, you should have it). But oxygen is optional(for documentation).

[RgnadKzin]

Nope, that wasn't it.

I changed the permissions of the src tree to user=root and group=users
I added OIS and recompiled everything using

cmake .
make
sudo make install
sudo ldconfig

Excepting OIS itself, where I had to

./bootstrap
./configure
make
sudo make install
sudo ldconfig

Here is the cmake of GG:

[bradbva@localhost GG]$ cmake .

What do I try next?

[OndrejR]

Try as normal user what says

whereis OGRE.pc

Also be sure to have FreeOrion requirements(from Ubuntu, pcLinuxOS may be something similar)

sudo apt-get install build-essential subversion pkg-config libltdl3-dev cmake
sudo apt-get install python2.6-dev libfreetype6-dev libsdl1.2-dev graphviz-dev libalut-dev libvorbis-dev libois-dev libtiff4-dev libopenal-dev

sudo apt-get install libboost-dev

especially pkg-config

Delete also file CMakeCache.txt and run cmake . again.

[RgnadKzin]

As a normal user:

[bradbva@localhost GG]$ whereis OGRE.pc
OGRE: /usr/local/lib/OGRE

Although it does not find OIS.pc on a whereis (?!)
Also, looks like everything is properly configured:

[bradbva@localhost GG]$ ls -la /usr/local/lib/pkgconfig/

My paths

$ whereis OIS.pc
OIS: /usr/include/OIS

$ whereis OGRE.pc
OGRE: /etc/OGRE /usr/lib/OGRE /usr/lib(64)/OGRE /usr/include/OGRE

You should have path /usr/local/...

If you have them in that directories, then something is wrong. In include directories should be files for development - C++ headers ending with extension .h

It all looks configured properly to me. The list of packages that you provided above are not called the same in the pcLinuxOS environment, but I think everything that has to be installed IS installed.

Where can I look?

[OndrejR]

According this howto you need to tell GG/cmake/FindOGRE.cmake(but this file is automatically called from main cmake) or directly found path in cmake cache or somehow tell cmake what variable ${OGRE_INCLUDE_DIR} is. But I am not expert on cmake.

Probably something like this(you need first to delete CMakeCache.txt)

cmake -DOGRE_INCLUDE_DIR=/usr/local/include/OGRE -DOIS_INCLUDE_DIR=/usr/local/include/OIS .

[Geoff the Medio]

I haven't read this thread carefully, so this might be irrelivant, but is it possible that FindOGRE.cmake is expecting a particular version of OGRE, and you're using a newer one that isn't recognized? It might just be a matter of updating a version number. This would be similar to issues some people have been having with Boost not being recognized by CMake's FindBoost.cmake, which has issues due to how Boost version numbering affects filenames of future versions in an unpredictable way.

[RgnadKzin]

I have been trying to work thru this on my own. I have gotten to the point where I am ready to compile freeorion/FreeOrion/GG. The cmake . that I run provides a couple of errors:

I then edit the CMakeCache.txt file and add the following:

Code: Select all

/Single output directory for building all libraries.
LIBRARY_OUTPUT_PATH:PATH=

OGRE_INCLUDE_DIR:PATH=/usr/local/include/OGRE

OGRE_LIBRARIES:STRING=/usr/local/lib/libOgreMain.so

OIS_INCLUDE_DIR:PATH=/usr/local/include/IOS

OIS_LIBRARIES:STRING=/usr/local/lib/libOIS.so

OIS_LIB_DIR:PATH=/usr/local/lib

My question is what is the name of the Ogre library?
Above, you can see I used libOgreMain.so

My question is what is the name of the Ogre library?

Have you tried using ccmake . to set the library and include directories, rather than editing CMakeCache.txt? It may not need to be told the specific library file name(s).

[RgnadKzin]

I filled in /usr/local/include/OGRE and OIS for the missing includes and /usr/local/lib for the missing lib_dirs and libraries.

It wants the name of an actual load library. For example, I know that I want libOIS.so, so I specify it for OIS_LIBRARIES.
When I configure again, I get no errors, but I have failed to point to an Ogre library.

That is what I think I am missing.

[Geoff the Medio]

What happens if you just specify the libdirs and not any specific library files in ccmake?

[RgnadKzin]

It drops the Ogre build.

Does it want the list of ogre related stuff in /lib?

[Geoff the Medio]

I don't know; if I did, I'd have said so by now.

On Windows, it just seems to hve OgreMain.lib for OGRE_LIBRARIES in GiGi's CMakeCache.txt and OIS.lib for OIS_LIBRARIES.

I don't think you should need to specify this though... maybe it's expecting pkgconfig to be present, or for Ogre to be installed (not just built)? But, I don't really know what I'm taking about, so maybe you do.
