curl linux
I use curl in my application. If I link it with -lcurl - symbols are undefined (libcurl3 installed), if I link with -lphobos2 - it links. So curl is linked with libphobos2.so? But what to do if I need static linking? (ubuntu 12.04 x86_64, dmd 2.063.2)

On Ubuntu, install one of these three packages: libcurl4-openssl-dev, libcurl4-gnutls-dev or libcurl4-nss-dev. For libcurl static linking you should link against all libraries that libcurl depends on. -- Jordi Sayol

But with -lphobos2 it links... Why linker don't find these symbols if libs are installed? Should I pass to linker some additional info in this case?

Can I see your full command line please? $ dmd -lcurl -- Jordi Sayol

That is in this case I have static linking but curl symbols are not definded somehow.
