LPC2368 uip demo GCC linker failsPosted by ESEMESE on January 13, 2009 When I try to build this demo from the download I get linker errors such as: mallocr.c:(.text+0x2c): undefined reference to `_sbrk_r' mallocr.c:(.text+0x3c): undefined reference to `_sbrk_r' mallocr.c:(.text+0x48): undefined reference to `_sbrk_r' and stdio.c:(.text+0x6e): undefined reference to `_lseek_r' stdio.c:(.text+0x86): undefined reference to `_write_r' This seems to refer to problems with missing code in newlib. Can anyone point me to the resolution of this? I am using the WINARM (GCC compiler). Thanks RE: LPC2368 uip demo GCC linker failsPosted by woops_ on January 13, 2009 Looks like the GCC library is not defined. Dont know why it is trying to use read and write in any case. Maybe set configUSE_TRACE_FACILITY to 0 in FreeRTOSConfig.h. You need to define the library used. Best to download yagarto and use that instead of winarm. RE: LPC2368 uip demo GCC linker failsPosted by ESEMESE on January 13, 2009 OK, I'll try that. Thanks.
