Solaris 9 Custom Library Error

Applications Programming

Gday People i have a library created in c++ that is used to control custom hardware. The library compiles fine, however when i compile a test program that links the library i get the following errors:

Undefined                       first referenced

Any help will be great!

Are all you dependencies in your LD_LIBRARY_PATH environment variable when compiling the test program?

Gday,

Yes my LD_LIBRARY_PATH dependencies seem to be set up fine.
When i do a ldd on the library all links seem to be fine as well

/usr/lib/libtds.so 
        libpthread.so.1 =>       /usr/lib/libpthread.so.1
        librt.so.1 =>    /usr/lib/librt.so.1
        libaio.so.1 =>   /usr/lib/libaio.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libmd5.so.1 =>   /usr/lib/libmd5.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libthread.so.1 =>        /usr/lib/libthread.so.1

I am compiling using

cc -I/usr/include -L/usr/lib -ltds main.c -o testit

I have managed to find the problem.

I needed to link libiostream and libCrun

using

-liostream -lCrun

Thankyou for your help which lead to this solution
