Problem s linkerom – C / C++ – Fórum – Programujte.com

(prepacte za repost ale predchadzajuce vlakno nemalo titulok, aj ked neviem preco je vobec povolene posielat bez titulku)


Caute,

mam problem (resp. neviem ako) s linkovanim. Stiahol som si Bullet physics engine 1.78 (http://bulletphysics.org/wordpress/), skompiloval a vsetko bolo vporiadku, taktiez aj dema fungovali (az na to ze pri soft body demach meshe bolo mozne vidiet len pri wireframe mode). Potom som si chcel vytvorit nejaky maly program ktory by pouzival bullet a ogre (http://ogre3d.org/).

#include <BULLET/btBulletDynamicsCommon.h>

a jses si opravdu jist, ze jsou v /usr/local/lib ty libBulletDynamics libBulletCollision libLinearMath ?? nemas to v jinem adresari nez v tomto?

KIIV: samozrejme, sam som ich tam kopiroval (a taktiez som naschval skusil dat zle napisane meno a vypisalo chybu ze nemoze najst kniznicu)

a nemas je treba zkompilovane pro 64bit a kompilujes pro 32?

to taktiez nie (a system mam 64 bitovy...a tie kniznice som taktiez kompiloval sam (cize to neni kompilovane nejaku inu platformu))

pak uz me napada jen ze by mohla chybet nejaka zavislost tem libkam ale ldd funguje jen na shared objektech.. tj .so

no na ich wiki pisu len o tychto 3 knizniciach a ano, ked dam ldd nejakeBulletDemo tak ziadne bulletovske kniznice nevypise
