[bullet] Undefined refernces compiling

[flx]

Hi, I've tried the static linked packages that are out there and the game looks very good, so i've been trying to run freeorion from the source in my archlinux box... and i've run into some problems, mostly my noobness when it comes to setting up build environments.
Some of them i could fix (the unseen GG as in the other post) but now i'm stuck with bullet.

It configures ok:

Code: Select all

scons: Configure: Checking for bullet >= 2.73...
pkg-config bullet --atleast-version 2.73
scons: Configure: yes

but building fails with errors like these

Code: Select all

UI/CollisionMeshConverter-human.o: In function `CollisionMeshConverter::CollisionShape() const':

CollisionMeshConverter.cpp:(.text+0x4a7): undefined reference to `btAlignedFreeInternal(void*)'

If you need any other output, i'll be happy to post it.

Thanks!

I'm guessing here since I don't use linux to build FreeOrion, but it might help to post the contents of your config.log and config.cache in the FreeOrion directory, and post the equivalents of what was asked for in this post but for bullet instead of GiGi / OGRE.

FO doesn't see bullet. Did you create symlinks as are described in wiki linux compile howto when compiling bullet?

Sorry for the late reply, but i didnt have much time to try until today. Let's see

I compiled bullet with yaourt wich didnt built the shared libraries unless its told to . Fixed that, symliked and ran ldconfig, they are /usr/lib instead of /usr/local/lib, but i guess that is distro specific and harmless as long as ldconfig knows where it is

Code: Select all

$ ldconfig -v | grep bullet
        libBulletSoftBody.so.2.73 -> libbulletsoftbody.so
        libBulletCollision.so.2.73 -> libbulletcollision.so
        libBulletDynamics.so.2.73 -> libbulletdynamics.so

Then cleaned/reconfigured/tried again but no luck.

Code: Select all

$ pkg-config --cflags bullet

yep, empty could that be the problem?

this is my bullet.pc

Code: Select all

$ cat /usr/lib/pkgconfig/bullet.pc
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: Bullet
Version: 2.73
Description: Bullet Physics library
Cflags: -I${includedir}

config.log and config.cache attached

Thanks!

Hi i've been trying some more and i've found a litle oddity (i'm starting to hate scons )

If I run

Code: Select all

$ scons configure

It can't find GiGiOgre

Code: Select all

[...]
Checking for GiGiOgre >= 0.6.0... (cached) no
[...]

but if I run

Code: Select all

$ scons configure --config=force

It finds it

Code: Select all

[...]
Checking for GiGiOgre >= 0.6.0... yes
[...]

How can i disable or clear scons cache?

[OndrejR]

delete config.cache or scons --clean

[flx]

Thanks for the fast reply

delete config.cache or scons --clean

Already tried, but it still uses cache

[OndrejR]

Try also delete in .sconf_temp all files except *.cpp and *.c

Didnt work, i'm checking out the project again.


edit: checking out clean half worked, it only configured boost from cache
edit2: configure ok with bullet but still fails compiling, i'll try building bullet again

If you have something like this:

Code: Select all

scons: Configure: Checking for bullet >= 2.73... no
...
scons: Configure: Checking for btVector3() in C++ library bulletmath... yes

It means bullet was successfully found(if you have bullet 2.73). Bullet pkg config file is missing, but it doesn't matter.

scons configure finds the pkg-config.

Code: Select all

Checking for bullet >= 2.73... (cached) yes

maybe it can't find the headers, but they are in /usr/include

I'll try to move the pkg config, so it finds it the other way
edit: hiding bullet.pc from pkg-config didnt work
