Re: SH2aeb support
Hi Carmelo. Thanks for the hint, Yes SVN:Trunk does solve the memcpy build issue it would seem. I have another issue I've not been able to figure out correctly. With Support global constructors and destructors turned off, uClibc doesn't seem to build crti.o and crtn.o, yet the linker still looks for them. These files get built if i turn on CTOR_DTOR but should they be built when this is switched off ? or should there be stub files created ? sh2aeb-linux-uclibc-gcc -Wl,-EB -Wl,-elf2flt=-s65536 test.c -o test /opt/sh/2a/toolchain/lib/gcc/sh2aeb-linux-uclibc/4.2.4/../../../../sh2aeb-linux-uclibc/bin/ld.real: crti.o: No such file: No such file or directory collect2: ld returned 1 exit status make[1]: *** [test] Error 1 make[1]: Leaving directory `/opt/sh/2a/build/src/test-apps-0.1' make: *** [build] Error 2 If I build with Support global constructors and destructors turned on, then I get linker errors as follows: test.elf2flt: In function `__uClibc_fini': (.text+0x908): undefined reference to `__fini_array_start' test.elf2flt: In function `__uClibc_fini': (.text+0x90c): undefined reference to `__fini_array_end' test.elf2flt: In function `__uClibc_main': (.text+0xa54): undefined reference to `__preinit_array_end' test.elf2flt: In function `__uClibc_main': (.text+0xa60): undefined reference to `__preinit_array_start' test.elf2flt: In function `__uClibc_main': (.text+0xa64): undefined reference to `__init_array_start' test.elf2flt: In function `__uClibc_main': (.text+0xa68): undefined reference to `__init_array_end' I've got round this so far by turning it on to build the files, then off to create something that links successfully, but I can't figure out how to get the crt[ni].o to build otherwise :( -- Cheers Kieran 2008/10/6 Carmelo Amoroso [EMAIL PROTECTED] Kieran Bingham wrote: Hi Guys, I'm currently trying to build uClibc-0.9.30-rc1 for SH2aeb and found an issue when building which I fixed with the attached patches. make[2]: Entering directory `/opt/sh/2a/build/src/test-apps-0.1' sh2aeb-linux-uclibc-gcc -Wl,-EB test.c -o test test.c: In function 'main': test.c:5: warning: return type of 'main' is not 'int' /opt/sh/2a/toolchain/usr/lib/libc.a(memcpy.o): In function `memcpy': memcpy.c:(.text+0x60): undefined reference to `WORD_COPY_FWD' collect2: ld returned 1 exit status make[2]: *** [test] Error 1 I think its the right thing to do - i.e. follow the SH4, and define ARCH_HAS_BWD, but then I had to copy the include from memmove to memcpy which I don't think is a particularly nice way to do this.

2008/10/6 Carmelo AMOROSO [EMAIL PROTECTED] Which is the target file format used to build uclibc. I'm not so aware of not elf format... if I guess correctly sh2a doesn't use elf format (as from -Wl,-elf2flt). indeed UCLIBC_FORMAT_FLAT=y If I build with Support global constructors and destructors turned on, then I get linker errors as follows: test.elf2flt: In function `__uClibc_fini': (.text+0x908): undefined reference to `__fini_array_start' If __UCLIBC_FORMAT_SHARED_FLAT__ is not defined, these symbols should not be referenced from __uClibc_fini. Are you sure uclibc has been properly configured ? Sorry if cannot help more on this. No Worries - thanks for your help already :) Hmmm looks like this is the relevant source in libc/misc/internals/__uClibc_main.c #if defined (__UCLIBC_CTOR_DTOR__) !defined (__UCLIBC_FORMAT_SHARED_FLAT__) extern void _dl_app_init_array(void); extern void _dl_app_fini_array(void); # ifndef SHARED /* These magic symbols are provided by the linker. */ extern void (*__preinit_array_start []) (void) attribute_hidden; ... I think my correct action is to look at getting the crt[ni].o to build without (__UCLIBC_CTOR_DTOR__) defined. I got stuck at the weekend on this, but I'll have another go at following the make rules tonight after work.
