在 Solaris 上，我可以使用crle命令来配置库路径，如下所示： 

crle -c /var/ld/ld.config -l /lib:/usr/lib:/usr/local/lib:/opt/DSI/32

我也可以使用传统的LD_LIBRARY_PATH方法，像这样： 

LD_LIBRARY_PATH="/export/home/donald/mysql-5.0.91-installed/lib/mysql/:/lib:/usr/lib"

Solaris 如何决定库路径？例如，Solaris 是否crle path先选择，然后LD_LIBRARY_PATH？我尝试google，但找不到答案。

答案在手册中（man ld.so.1）。

 The runtime linker uses a prescribed search path for  locat-
 ing  the  dynamic  dependencies  of  an  object. The default
 search paths are the runpath recorded in  the  object,  fol-
 lowed  by  a  series  of  defaults.  For 32-bit objects, the
 defaults are /lib followed by /usr/lib. For 64-bit  objects,
 the  defaults  are  /lib/64  followed  by /usr/lib/64. These
 defaults component can be  modified  using  a  configuration
 file  that is created with crle(1). The runpath is specified
 when the dynamic object is constructed using the  -R  option
 to  ld(1).  The  environment variable LD_LIBRARY_PATH can be
 used to indicate  directories  to  be  searched  before  the
 default directories.

所以，顺序是：

  1. LD_LIBRARY_PATH
  2. 共享对象 RPATH
  3. crle默认值
