There are several - limitations to using a Windows native toolchain in a Cygwin environment. - The three biggest are: - - 1. The Windows toolchain cannot follow Cygwin paths. Path conversions are - performed automatically in the Cygwin makefiles using the 'cygpath' - utility but you might easily find some new path problems. If so, check - out 'cygpath -w' - - 2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic - links are used in Nuttx (e.g., include/arch). The make system works - around these problems for the Windows tools by copying directories - instead of linking them. But this can also cause some confusion for - you: For example, you may edit a file in a "linked" directory and find - that your changes had no effect. That is because you are building the - copy of the file in the "fake" symbolic directory. If you use a - Windows toolchain, you should get in the habit of making like this: - - make clean_context all - - An alias in your .bashrc file might make that less painful. - - 3. Dependencies are not made when using Windows versions of the GCC. This - is because the dependencies are generated using Windows pathes which do - not work with the Cygwin make. - - MKDEP = $(TOPDIR)/tools/mknulldeps.sh - - An additional issue with the WinAVR toolchain, in particular, is that it - contains an incompatible version of the Cygwin DLL in its bin/ directory. - You must take care that the correct Cygwin DLL is used. - -NuttX buildroot Toolchain -^^^^^^^^^^^^^^^^^^^^^^^^^ - - If NuttX buildroot toolchain source tarball cne can be downloaded from the - NuttX SourceForge download site (https://sourceforge.net/projects/nuttx/files/). - This GNU toolchain builds and executes in the Linux or Cygwin environment. - - 1. You must have already configured Nuttx in <some-dir>/nuttx. - - cd tools - ./configure.sh amber/<sub-dir> - - NOTE: you also must copy avr-libc header files into the NuttX include - directory with command perhaps like: - - cp -a /cygdrive/c/WinAVR/include/avr include/. - - 2. Download the latest buildroot package into <some-dir> - - 3. unpack the buildroot tarball. The resulting directory may - have versioning information on it like buildroot-x.y.z. If so, - rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot. - - 4. cd <some-dir>/buildroot - - 5. cp configs/avr-defconfig-4.5.2 .config - - 6. make oldconfig - - 7. make - - 8. Edit setenv.h, if necessary, so that the PATH variable includes - the path to the newly built binaries. - - See the file configs/README.txt in the buildroot source tree. That has more - detailed PLUS some special instructions that you will need to follow if you - are building a toolchain for Cygwin under Windows. - -avr-libc -^^^^^^^^ - -Header Files - - In any case, header files from avr-libc are required: http://www.nongnu.org/avr-libc/. - A snapshot of avr-lib is included in the WinAVR installation. For Linux - development platforms, avr-libc package is readily available (and would - be installed in the apt-get command shown above). But if you are using - the NuttX buildroot configuration on Cygwin, then you will have to build - get avr-libc from binaries. - -Header File Installation - - The NuttX build will required that the AVR header files be available via - the NuttX include directory. This can be accomplished by either copying - the avr-libc header files into the NuttX include directory: - - cp -a <avr-libc-path>/include/avr <nuttx-path>/include/. - - Or simply using a symbolic link: - - ln -s <avr-libc-path>/include/avr <nuttx-path>/include/. - -Build Notes: - - It may not necessary to have a built version of avr-lib; only header files - are required. Bu if you choose to use the optimized libraru functions of - the flowing point library, then you may have to build avr-lib from sources. - Below are instructions for building avr-lib from fresh sources: - - 1. Download the avr-libc package from: - - http://savannah.nongnu.org/projects/avr-libc/ - - I am using avr-lib-1.7.1.tar.bz2 - - 2. Upack the tarball and cd into the - - tar jxf avr-lib-1.7.1.tar.bz2 - cd avr-lib-1.7.1 - - 3. Configure avr-lib. Assuming that WinAVR is installed at the following - loction: - - export PATH=/cygdrive/c/WinAVR/bin:$PATH - ./configure --build=`./config.guess` --host=avr - - This takes a *long* time. - - 4. Make avr-lib. - - make - - This also takes a long time because it generates variants for nearly - all AVR chips. - - 5. Install avr-lib. - - make install +This port was tested using the OS X / CROSSPACK tool chain, GCC version 4.8.1. +Please see other NuttX documentation for toolchain details.
