progress ... i thinkin some forum posts i've read 64bit dmd uses a differnt linker which supports coff
atleast i can now link my app in 64bit mode without errors dmd -m64 source/app.d OpenVG.lib
also an exported test function prints to stdout, so my problem is solved for x64 :)
if anyone could explain how this could be done with 32bit builds i'd appreciate it
why does dmd use different linkers for 32 and 64bit anyway?
