[oi-dev] perl module compilation: symbol reference warning.

[Rouven WEILER]

Hey there,

I built a slightly customized perl module DBD-SQLite-1.58 with OpenIndiana's perl-522.
During the built process I get a line warning about symbol referencing errors.
Nevertheless, the packages passes all tests.

Adding arguments for explicitly linking against libperl.so solves the warning, bit adds libperl.so to the ELF header's needed libraries section.

Although it is "just" a warning I want to get rid of this warning. Experience shows that such warnings become errors very fast and then the solution is needed.
Some other packages already threw errors about referenced symbols coming from libperl.so
And on linux systems there is no such warning, which makes me think that there is something special about OpenIndiana.

Compiling the plain uncustomized package as it is downloadable from cpan it shows the same warning.

Thanks in advance.

Here now the offending warning including the linker line:
