[求助]关于SCO下编译多线程的问题？

classover

我在SCO5.0.7(已经装了mp3和FSUpthread 3.5c)下编译一个简单的测试程序(linux 下正常)，编译命令如下：gcc pthtest.c -o pthtest -lgthreads,结果报告如下错误：
In file included from /usr/include/pthread.h:40,
                 from pthtest.c:4:
/usr/include/pthread/signal.h:101: redefinition of `struct timespec'
In file included from pthtest.c:4:

/usr/include/pthread.h:386: conflicting types for `pthread_t'
/usr/include/sys/types.h:247: previous declaration of `pthread_t'

大概是说sys/types.h 与pthread.h的定义重复，结果郁闷了好几天都解决不了，请诸位高人帮帮忙，小弟感激不尽

设置下LD_LIBRARY_PATH

请问具体怎么设置？是在gcc 下添加 libgthread.a 的路径吗？我装过FSUpthread 3.9，不过都是一样错误，后来嫌弃麻烦（每次编译都要加 －L/usr/local/include -I/usr/local/lib)删了，现在Mysql都装不上了

小弟是新手，万望各位多多指教！

没什么人气啊 ，自己顶一下，呵呵！

真是人微言轻啊！还是自己解决了

/etc/ld.so.conf文件里面加上你的lib的路径
然后ldconfig

是这样的么?
好象这样就可以不用每次都用L来指定lib的地址了

谢谢了，坛子里还是有不少热心的朋友的。
  SCO Openserver下好像没有这个文件，我一般都是在.profile中添加LD_LIBRARY_PATH的。
   我发现好像是MP3的问题，没装MP3之前types.h是8K，装了后是13K。后来我卸载了MP3，装上MP1，就一切正常了
