Hi AT91, I am trying to build an AT91 GNU sample project, "getting-started-project-at91sam7x-ek". Here is the problem code. Code: //------------------------------------------------------------------------------ // Global Variables //------------------------------------------------------------------------------ // Required for proper compilation. struct _reent r = {0, (FILE *) 0, (FILE *) 1, (FILE *) 0}; struct _reent *_impure_ptr = &r; The code is in ../at91lib/utility/stdio.c:64, however "struct _reent" is not defined in this source or any included headers, resulting in "error: variable 'r' has initializer but incomplete type". I am using the latest CodeSourcery G++ Lite toolchain on Linux. Searching Google doesn't provide any useful clues, please can you help me? Best regards, weartronics |

I have not resolved this problem, but a workaround appears to be to use the GNUARM toolchain. |

The new bootstrap for the at91sam9g20 has the same problem. Seems that it can only be built with the CodeSourcery toolchain. Not very nice. I have a toolchain under linux (using buildroot). Building the old bootstrap there is no problem, but the new one has this problem. I really don't want to use CodeSourcery just for one bootstrap. |

I asked the Atmel support and just got this link as an answer: http://support.atmel.no/bin/customer?=& ... try&id=898 It seems to be not possible to use something else than the CodeSourcery Toolchain. Not nice, but there is no other solution. |

It looks like you have to use exactly the right version of compiler: To get sam-ba applets to compile under linux I had to use Sourcery G++ Lite 2008q3-39 for ARM EABI from http://www.codesourcery.com/sgpp/lite/a ... release567 Anything newer or older gave (different) errors. |

Yep, this version works. Thanks a lot, I appreciate it.
