Global variables are not initialized in shared libraries

[Grigori]

Hi all,

I have built a shared library with several global variables. Their constructors are not called when the library is loaded. Where the problem may be? The same code work perfectly on Linux.
Compiler is GCC 3.2.2. Linker command line options are "g++ -Wl,s -fPIC -shared -Wl,-b ...".

Thanks in advance for any help...

i think you need to include libstd++.sl in the link line (if its not already being included by g++). what does the actual link line (as can be seen with g++ -v option) look like ?

whats -Wl,s ? i guess you meant -Wl,+s or -Wl,-s.

Here is the g++ output:

i dont seem to have access to an installation of gcc hppa-2.0w rightaway. this seems to work with gcc 3.2 hppa-2.0n. i'll try to get more info on this.

by the way, what makes you choose hppa2.0w over hppa2.0n, since both build only 32bit objects?

I'm sorry, I'm not an expert in this field. GCC was configured and built from sources on that machine. How can I switch between hppa2.0w and hppa2.0n?
And what will be the difference between them?
