Error building my own toolchain

[Sgalperin]

I have been trying to follow the “Building You Own GNU Toolchain” example and I’m getting an error that I don’t understand.

I installed MinGW and Msys per the instructions. Then I downloaded binutils-2.23.0 from the GNU archive. I created the directories and did the configure and make commands per the tutorial, and I get the following error:

checking whether to build shared libraries… yes
checking whether to build static libraries… yes
checking how to run the C++ preprocessor… /lib/cpp
configure: error: in `/c/gnu/binutils-2.23.0-build/ld’:

See `config.log’ for more details.

Any idea what this is about?

Hi,

The problem lies here:

COLLECT_GCC=c:SysGCCpowerpc-eabipowerpc-eabibing++.exe

You should be using the MinGW’s gcc to build the cross-toolchain as you are trying to build a cross-toolchain that will be run on Windows not on PowerPC. Furthermore, make sure that there are no other gnu toolchains on the PATH that could confuse the build process. Do not forget to set the target to powerpc-wrs-vxworks instead of arm-eabi as in the example.

[Sgalperin]

How does COLLECT_GCC get set?

[ket]

Hi,

Check that there are no other GNU toolchain directories defined on the PATH variable. Make sure to build the toolchain from within MinGW shell.

[Sgalperin]

OK, got all the extraneous compilers out of the path, including cc.exe in the MinGWbin directory.

Now it’s asking for GMP, MPFR and MPC. I’m assuming that they need the same style directory structure that I used for binuitls and gcc. However they don’t take the –target option on configure. Any suggestions?

[ket]

Hi,

Simply extract those libraries to the respective GMP, MPFR and MPC directories under the built gcc directory. GCC will then configure and build them automatically as a part of its own build process.

[Sgalperin]

OK. I have everything downloaded and put in directories as advised by the folks at GNU. When make goes into the ./libcpp directory it errors out. Here is the display:

Hi,

Look into config.log for the exact cause of the error. The compiler is probably complaining about missing headers, you need to copy the system headers from your vxworks powerpc target to either sysrootusrinclude if you are using sysroot or include if not. The location depends on how it is done for vxworks powerpc.

[Sgalperin]

The source of the error appears to be in the build for the std lib. It’s looking for g++ as a compiler which isn’t in the MinGW distribution.

From config.log in the libcpp directory:

configure:4850: result: yes
configure:4901: g++ -c conftest.cpp >&5
/c/gnu/gcc-4.8.1/libcpp/configure: line 1495: g++: command not found

Hi,

Please reinstall MinGW selecting “C++ compiler” in the installer options. Alternatively you can use a prebuilt package from http://gnutoolchains.com/mingw32/

[Sgalperin]

The C++ installation got me farther than ever, the build took over 2 hours to fail. Now it’s missing stdio.h.

Hi,

Is stdio.h provided by vxworks? If yes, have you copied the system headers over from vxworks as instructed before?
