nenapada niekoho ako skompilovat jpcap na 64bit systeme?

make dava error:

/usr/bin/ld: /tmp/ccWFe5Db.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/tmp/ccWFe5Db.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libjpcap.so] Error 1

som sa dogooglil len k tomu ze je to architecture issue ale ziadne riesenie..

kedze pouzivam arch tak som podla tohto spravil 32bit envitroment a skompiloval to tam. tvari sa ze to funguje.

00000101000635400006354202109677000636920454460604545068

CFLAGS="-fPIC" make ...

00000101000635400006354202109677000636920454460604544696

niekde v makefile by malo byt, ze gcc bla bla bla -fpic bla bla bla

skus to zmenit na gcc bla bla bla -fPIC bla bla bla

... je dost mozne, ze to bude aj v nejakej premennej, napriklad CFLAGS, alebo LDFLAGS...

Makefile

nie je to tam

000001010006354000063542021096770006369204544606045446960454472404545157

ifeq ($(PLATFORM), Linux)
JNI_INCLUDE2 = $(JAVA_DIR)/include/linux
-- COMPILE_OPTION = -shared -L.
++ COMPILE_OPTION = -shared -fPIC -L.

ak nepomoze, viac uz neviem

00000101000635400006354202109677000636920454460604544696045447240454515704545471

toto ma posunulo k tomuto:

/usr/lib/gcc/x86_64-unknown-linux-gnu/4.3.3/../../../../lib/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [libjpcap.so] Error 1

pridanie -fPIC do cflags nespravi nic

0000010100063540000635420210967700063692045446060454469604544724045451570454547104546263

si v pici

000001010006354000063542021096770006369204544606045446960454472404545157045454710454626304546417

kebyze to skompilujem na 32bit a potom vysledok nakopirujem? .)

00000101000635400006354202109677000636920454460604544696045447240454515704545471045462630454641704546445

no, ak to vylozene nepotrebujes 64bitove, kludne mozes ten program skompilovat ako 32bit a pouzit v 64bit systeme, ak mas layer pre podporu behu 32bitovych programov.
