Hello,

You just have to download STLPort library for www.stlport.org 

Then include it into your project.

I have made some hacks, so that it compiles. Most of them are quick and dirty, but they work fine for me. Hopefully someone more gifted than me can improve them and feed them back to the list.
I have attached a patch (against STLPort 4.6).

Regards,
Dirk

thanks so much. Question: are you using a GCC-3.x or GCC-2.95.x based
toolchain?

Regards.

I've applied the patch(there was a small bump in the road, since my
patch command didn't grok the patch format, fixed patch attached), but I
run into problems with include files which I don't understand.

From my toolchain:

./ecos/gnutools/arm-elf/arm-elf/include/bits/functexcept.h
./ecos/gnutools/arm-elf/arm-elf/include/exception
./ecos/gnutools/arm-elf/arm-elf/include/exception_defines.h
./ecos/gnutools/arm-elf/arm-elf/include/stdexcept

Here is the error messsage:

All the people I know (including me) use STLPort (www.stlport.org) without streams as their STL implementation. It can be configured to work with ecos, but it's a bit tricky in some places. Give it a try.

I get the impression that there are people out there that use STL
w/eCos. There are numerous posts that hint as much in ecos-discuss, but
I didn't find any "howto".



Specifically I'm interested in "class string".




This is how far I got:


--- test app ---

#include <stdio.h>
void remove();
void rename();
void tmpfile();
void tmpnam();
#include <memory>
#include <string>

void test()
{
	std::string xx="abc";
//	string yy=xx+"kljasdf";
}


--- test app ---

Once I twisted the arm of GCC to compile the thing, I got these linking
errors:

---- linking errors ----

output/./xxx.o: In function `test()':
/cygdrive/c/e21/workspace/firmware/xxx.cc:13: undefined reference to

>::~basic_string [in-charge]()'
collect2: ld returned 1 exit status
make: *** [output/rimi.bin] Error 1

---- linking errors ----


After a bit of googling, I discovered that I was missing various things
in libstdc++ that explicitly instantiates templates, e.g.:


http://savannah.gnu.org/cgi-bin/viewcvs/*checkout*/gcc/gcc/libstdc++-v3/src/allocator-inst.cc?rev=HEAD&content-type=text/plain


Although I could make some linker errors disappear as I pasted in bits
of code from the savannah CVS, I was always left with a couple of more
linker errors...
