※ 发信站: 批踢踢实业坊(ptt.cc) : ◆ From: 140.115.200.121 : 推 andytzeng:gcc 编译可以指定 version, name 03/16 09:56 : → andytzeng:http://blog.twpug.org/category/30/88 参考一下 03/16 09:57 我其实在man ldconfig时也查出一些蛛丝马迹. man ldconfig: ldconfig checks the header and file names of the libraries it encounters when determining which versions should have their links updated. 然後我 $ strings libgtk-x11-2.0.so.0.1000.10 |grep libgtk-x11-2.0.so.0 果然有libgtk-x11-2.0.so.0 然後去google搜到这一篇: http://sources.redhat.com/ml/libc-alpha/2004-09/msg00139.html 後来man ld发现这一段: -soname=name When creating an ELF shared object, set the internal DT_SONAME field to the specified name. 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. 所以我原来的问题要这样解决: $ 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 (还是感谢andytzeng帮忙.) -- Albert Einstein : If there is any religion that could cope with modern scientific needs it would be Buddhism. 《金刚经》离一切诸相，则名诸佛。 http://web.cc.ncu.edu.tw/~93501025/jg.doc --
