When an executable is linked with a shared object which has a DT_SONAME field, then when the executable is run the dynamic linker will attempt to load the shared object specified by the DT_SONAME field rather than the using the file name given to the linker. 所以我原來的問題要這樣解決: $ gcc h.c -c $ ld h.o -o libh.so.0 -shared -fPIC -soname libh.so.0 $ ln -s libh.so.0 libh.so $ gcc test.c -o test -L. -lh $ ldd test (還是感謝andytzeng幫忙.) -- Albert Einstein : If there is any religion that could cope with modern scientific needs it would be Buddhism. 《金剛經》離一切諸相，則名諸佛。 http://web.cc.ncu.edu.tw/~93501025/jg.doc -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.115.200.121
