Re: [KOS] trouble with standard library

Your test program. Assuming you’re starting from the PNG example Makefile, find this portion of the Makefile: example.elf: $(OBJS) romdisk_boot.o $(KOS_CC) $(KOS_CFLAGS) $(KOS_LDFLAGS) -o $@ $(KOS_START) $^ -lpng -lz -lm $(KOS_LIBS) Change it to look like this: example.elf: $(OBJS) romdisk_boot.o kos-c++ -o $@ $^ -lpng -lz -lm If you’re not using a romdisk, get rid of the romdisk_boot.o stuff too, of course. - Lawrence > On Dec 29, 2016, at 11:48 PM, Nathan Meier <gro...@gm...> wrote: > > Are talking about KOS's Makefile or my test program's Makefile? > > On Thu, Dec 29, 2016 at 7:42 PM, Lawrence Sebald <blu...@gm... <mailto:blu...@gm...>> wrote: > Compile and link with kos-c++ in your Makefile, rather than $KOS_CC or whatever it is your makefile is currently using. > > The issue here is that you’re not linking in the standard C++ library at all, which causes problems if you try to use any of it. > > - Lawrence > > > On Dec 29, 2016, at 10:24 PM, Nathan Meier <gro...@gm... <mailto:gro...@gm...>> wrote: > > > > So I'm in the process of converting code over from c to c++.(The code was based of the PNG example.) > > > > Currently I'm trying to use functions from the standard library like #include<vector>, #include<string> and #include<fstream>. > > > > When I try and compile the program in Cygwin.
