Hi, I've got this project that requires me to link into a C++
backend. It works just fine when using GDC:
gdc *.d [client libraries]
However, this command using DMD does not work:
dmd -L-lstdc++ *.d [client libraries]
I still get errors involving the standard library not being
added
like:
/usr/include/c++/4.8/iostream:74: undefine reference to
`std::ios_base::Init::Init()'
(etc.)
What do I need to do to make this work? Thanks.
I don't know why that's happening, but you can explicitly link
using gcc (or ld/gold directly) if you need to. E.g.
dmd -c myFile.d
gcc myFile.o -lphobos2
or whatever is necessary on your project/system.
I had wanted to try this too, but I wasn't sure if the linker
knew where phobos2 was on my system. I just tried this now for
funsies:
dmd -c *.d
g++ main.o [client files] -lphobos2
With or without that -lphobos2 flag, I get errors like these:
main.d(.text._Dmain+0x18e): undefined reference to
`D3std5stdio16__T7writeln(TAyaZ7writeFAyaZv'
