About GCC And MSVC Compatibility - gcc

Does every source code that can compiled in GCC also can compiled in MSVC or they have some difference in implementation of C/C++ standard?

What are arm-none-eabi-c++ and arm-none-eabi-cpp for?

I'm using the GNU Arm Embedded Toolchain to cross-compile on Windows, and was wondering what the following highlighted executables were used for. There are already arm-none-eabi-gcc and arm-none-eabi-g++ for compiling C and C++ code respectively, so I'm guessing arm-none-eabi-c++ and arm-none-eabi-cpp handle some sort of C++ pre-processing or linking of C++ libraries?
c++ is the common "standard" name for a C++ compiler. It's the same as g++.
cpp runs the preprocessor only.

Mixed Clang and GCC

Are there any good reference projects that mix Clang and GCC?
My use case here is compiling OpenMP code with GCC and everything else with Clang. Added bonus if CMAKE supported this somehow.

On Solaris, are libraries compiled with gcc usable the same way as for libs generated with cc?

I am currently trying to compile libxml2 on Solaris. When I run the ./configure script provided with the sources, the gcc and g++ compilers are automatically used. However, I would like to use cc and CC compilers. So I run :
./configure CC=cc CXX=CC
It works but then, when I run "make", I get some errors which prevent the libraries to be generated.
When gcc and g++ are used, everything goes well with no errors, so I was wondering: can I use the librairies generated with gcc/g++ the same way I would have used them if I had successively generated them with cc/CC?
What are the differences between a lib generated with cc and the same lib generated with gcc on Solaris?
You can use either the gcc or cc C compilers pretty much interchangeably.
You can mix the g++ and CC C++ compilers in certain ways, but only on x86 Solaris and if your CC compiler is new enough to have the -compat=g option available.
The GNU g++ and the Solaris Studio CC C++ compilers default to completely different ABIs and C++ run-time libraries. On x86 Solaris platforms, newer versions (since version 12.?, if I remember correctly) provide a -compat=g option to use the g++ ABI and run-time libraries. The Studio 12.4 CC compiler adds a -std=v option to select different versions of the g++ or Sun C++ ABI and run-time libraries:
c++03 (zero-3, not oh-3)
Equivalent to the -compat=g option. It selects C++ 03 dialect and g++ ABI; it is binary compatible with g++ on Solaris and Linux It
sets the __SUNPRO_CC_COMPAT preprocessor macro to 'G'.
c++11
Selects C++ 11 dialect and g++ binary compatibility. It sets the __SUNPRO_CC_COMPAT preprocessor macro to 'G'.
c++0x (zero-x, not oh-x)
Equivalent to c++11.
and
The -std=c++03 provides compatibility with the gcc/g++ compiler on
all Oracle Solaris and Linux platforms.
With -std=c++03, binary compatibility extends only to shared
(dynamic or .so) libraries, not to individual .o files or archive (.a)
libraries. The gcc headers and libraries used are those provided with
the compiler, rather than the version of gcc installed on the system.
Note that the Studio 12.4 CC compiler uses the g++ headers and libraries supplied bundled with the CC compiler itself. 12.3 and earlier use the g++ headers and libraries installed on the system under /usr/sfw.
On SPARC Solaris, you have to use either g++ or CC for the entire application.

g++ (tdm-1) 4.7.1 doesnt support all c++11 features

it's supposed g++ (tdm-1) 4.7.1 that comes with codeblocks for windows support all C++11 features, std::stoi(str) isnt reconized, same for other c++11 functions. (string header is included).
Do i need to look for another compiler ?
This is due to missing C library functions in MinGW, see the last few comments on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=37522
I made some improvements so it is supported in MinGW GCC 4.9 and later, so you could just upgrade to a later TDM build.

Specify compiler NVCC uses to compile host-code

When running nvcc, it always uses the Visual C++ compiler (cl.exe). How can I make it use the GCC compiler?
Setting the CC environment-variable to gcc didn't fix it. I also couldn't find any option for this in the executeables help-output.
On Windows, NVCC only supports the Visual C++ compiler (cl.exe) for host compilation.
You can of course compile .cpp (non-CUDA) code using GCC and link the objects with objects generated by nvcc.
