[Code:Blocks, c++] Program ne najde knjižnice

[Code:Blocks, c++] Program ne najde knjižnice

gtu ::

Pozdravljeni,
soočam se s težavo pri programiranju v Code:Blocks.
Platforma: nVidia Jetson ARM
uporabljene knjižnice: OpenCV, BaslerSDK, GigEApi

Program se uspešno prevede, pri zagonu pa reče, da ne ne najde določene knjižnice, ki bi jo rad uporabil.
Mislim, da so nastavitve linkerja in compilerja nastavljene vredu, ker sem dodal vse možne poti in knjižnice ki naj bi jih program rabil.

Ima to opraviti s premenljivkami okolja?

V LD_LIBRARAY_PATH sem tudi dodal poti do knižnic, vendar nič ne pomaga.

Hvala za nasvete!
Lp

Mavrik ::

Kaj ti pokaže "ldd tvoj_program"?

Nasvet: Naslednjič napiši TOČNO na katerem OSu delaš, težko ti ljudje pomagajo če jim ne podaš informacij, ki so pomembne. Recimo operacijski sistem, prevajalnik, verzija prevajalnika, celoten output prevajanja....
The truth is rarely pure and never simple.

Randomness ::

Napiši, kaj ti izpiše 'echo $LD_LIBRARY_PATH' v terminalu, v katerem poženeš svoj program.

Randomness ::

Če prav razumem tvojo težavo, ti želiš pognati svoj program direktno iz Code::Blocks IDE-ja? Ker po tvojem ldd izpisu sodeč, bi se moral iz terminala, v katerem si pognal ldd, tvoj program pravilno zagnati. Vsaj ld očitno najde vse potrebne knjižnice. Kaj reče ukaz 'file /opt/pylon4/genicam/bin/Linux32_ARM/libGenApi_gcc43_v2_3.so'?

gtu ::

Tako nekako, ko kliknem na zeleno puščico za poganjanje programa v CodeBlocks, mi sicer program zažene, a ne najde dotične knjižnice.
Res mi je čudno.

Ukaz file... reče:

 /opt/pylon4/genicam/bin/Linux32_ARM/libGenApi_gcc43_v2_3.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, not stripped

Randomness ::

Pa si poskusil pognati program iz terminala - iz tistega, v katerem si prej pognal ldd tvoj_program? Problem je verjetno v tem, da Code::Blocks pri zagonu programa ne nastavi spremenljivke LD_LIBRARY_PATH. To je drugače možno rešiti na več načinov; najprej poskusi pognati Code::Block iz terminal, v katerem predhodno nastaviš spremenljivko LD_LIBRARY_PATH.

gtu ::

Prej nisem, ker sem mislil, da nima smisla, sedaj pa sem poizkusil še to in zadeva deluje! Se pravi, da je problem samo v tem, da CodeBlocks ne ve kam gledat.

Zgodovina sprememb…

  • spremenil: gtu ()

Randomness ::

Tako je. Malo si poglej, kako "delujejo" okoljske spremenljivke in pa dynamic linker (man ld.so).

Ok, hvala za pomoč!
