g++ linking problem with multiple libraries on solaris 2.7

["Qiegang Long" <qlong at mindspring dot com>]

Hi,

 

On Solaris 2.7 with gcc-2.9.5, I am having a strange problem with g++.

 

I have over 100 source files for  a library. If I compiled all the sources file and generate one big static library with "ar" command,

my test program can be successfully linked to the library.  However,  if I organize those files into two sets, then use "ar" to generate

two static libraries, my test program cannot be linked successful with the two new libraries. The error  is some symbols in one

library cannot be resolved, although those symbols are defined in the other library.

 

For example, I generated libex1.a and libex2.a, to link  test program mytest,

 

$ g++ -o mytest.o libex1.a libex2.a -L/usr/local/lib -lstdc++

 

the error is some symbols in libex2.a cannot be resolved, although those symbols are defined in libex1.a.

 

Is this a known problem?

 

Any help is appreciated.
