Does the SDK support STL?

[mrbrown]

Have you tried it? Unfortunately the PSPSDK developers cannot test every configuration a user might use, and we can only fix or implement things once we know what's broken or missing.

Admittedly I haven't even tried compiling a C++ program, but the support for C++ and the the STL should be in psptoolchain (libstdc++ and newlib). What happens when you build a program using the STL?

I tried to convert sdktest to a cpp program by just renaming main.c to main.cpp but I get this error:

Yeah TyRaNiD found this one and I think he fixed it. If not a fix will be going into Subversion soon.

Just put extern in front of the definition of module_info (inside the PSP_MODULE_INFO macro) on line 62 of pspsdk/sdk/kernel/pspmoduleinfo.h.

Oh yes, I figured that out after fiddling a bit.

Now I'm having problems linking in libstdc++.

psp-gcc -I. -I/usr/local/pspdev/psp/sdk/include -O2 -G0 -Wall -L/usr/local/pspd
ev/psp/lib -L. -L/usr/local/pspdev/psp/sdk/lib -lstdc++ main.o -lpspdebug -lp
splibc -lpspkernel -o cpptest.elf
main.o: In function `__static_initialization_and_destruction_0(int, int)':
main.cpp:(.text+0x244): undefined reference to `std::ios_base::Init::~Init()'
main.cpp:(.text+0x24c): undefined reference to `std::ios_base::Init::Init()'
collect2: ld returned 1 exit status
make: *** [cpptest.elf] Error 1

Order of object files matters to the GNU linker. Try putting -lstdc++ after main.o.

Yes I also thought that would be the problem. I've tried putting it before and after libc. That gave me alot of errors complaining about missing references to functions that should be in libc. Wich reminded me of reading that psplibc was just a limited set of functions. Then I tried defining this "USE_NEWLIB_LIBC = 1" but I still get alot of errors:

Newlib libc depends on "system calls" that we've implemented in PSPSDK's pspglue library. From your output, it looks like you haven't upgraded to the 0625 PSP toolchain, because it should be looking for those names with underscores in front of them.
