Hi all, I'm trying to build gcc-3.2.3 under the Cygwin environment. I am following my own rules for building under Linux at http://www.asisi.co.uk/or1kecos.html but I cannot build gcc-3.2.3 - I get the following error: make: Entering directory `/home/or1k-cvs/or1k/b-gcc' make[1]: Entering directory `/home/or1k-cvs/or1k/b-gcc/libiberty' make[2]: Entering directory `/home/or1k-cvs/or1k/b-gcc/libiberty/testsuite' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/home/or1k-cvs/or1k/b-gcc/libiberty/testsuite' make[1]: Leaving directory `/home/or1k-cvs/or1k/b-gcc/libiberty' make[1]: Entering directory `/home/or1k-cvs/or1k/b-gcc/gcc' gcc -DIN_GCC -DCROSS_COMPILE -g -O2 -W -Wall -Wwrite-strings -Wstrict-prot otypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -DHAVE_C ONFIG_H -DGENERATOR_FILE -o gengenrtl.exe \ gengenrtl.o ../libiberty/libiberty.a ../libiberty/libiberty.a: could not read symbols: Archive has no index; run ranlib to add one collect2: ld returned 1 exit status make[1]: *** [gengenrtl.exe] Error 1 make[1]: Leaving directory `/home/or1k-cvs/or1k/b-gcc/gcc' make: *** [all-gcc] Error 2 make: Leaving directory `/home/or1k-cvs/or1k/b-gcc' I have tried running ranlib on libiberty.a as suggested in the error report (although I think it already did this in the make process) but it made no difference. Of course I never had this problem on Linux - can anyone give me some ideas as to what might be going wrong? Thanks in advance, Robert PS - I will get the page onto Opencores at some point - have just been busy with other stuff.

Well, just about a

with gcc-3.4.2 in the cvs. This should work... (well it worked for me)

best regards,

I get exactly the same error when building gcc-3.4.2. See attached log.

I note there are differences between the ATS script but I do need to build C++ in and use newlib for eCos support.

OK - found the problem. It was finding the wrong 'ar' due to path order. It might have been sensible to follow my document verbatim :-) Robert Cragie, Design Engineer _______________________________________________________________ Jennic Ltd, Furnival Street, Sheffield, S1 4QT, UK http://www.jennic.com Tel: +44 (0) 114 281 2655 _______________________________________________________________

Hi Robert, I have a question about newlib. You say in your webpage that in order to compile gcc to run with eCos you have to download newlib-1.11 from newlib webpage. But the official version hasn't got inside the or32 machine port, so I am quite amazing that it works. Do you know why?

Hi Javier, I'm not 100% sure - I just got the information from here: http://ecos.sourceware.org/build-toolchain.html IIRC, newlib is just a library to replace glibc to prevent GNU copyleft issues - important for embedded software. So it's simply compiled with or32-elf-gcc as far as I know and doesn't itself need or32 support - or at least the bit required by eCos doesn't. It is probably worth noting that a newer version of newlib is required if building with a later GCC - my latest build with GCC 3.3.3 failed and I had to apply the following patch: diff -rc newlib/libc/ctype/iswctype.c ../gcc-3.4.2/newlib/libc/ctype/iswctype.c *** newlib/libc/ctype/iswctype.c Fri Sep 20 21:13:10 2002 --- ../gcc-3.4.2/newlib/libc/ctype/iswctype.c Tue Feb 8 14:22:28 2005 *************** *** 62,67 **** --- 62,68 ---- case WC_XDIGIT: return iswxdigit (c); default: + return 0; } /* otherwise unknown */ diff -rc newlib/libc/ctype/wctype.c ../gcc-3.4.2/newlib/libc/ctype/wctype.c *** newlib/libc/ctype/wctype.c Fri Sep 20 21:13:10 2002 --- ../gcc-3.4.2/newlib/libc/ctype/wctype.c Tue Feb 8 14:23:46 2005 *************** *** 121,126 **** --- 121,127 ---- return WC_XDIGIT; break; default: + break; } /* otherwise invalid */ Note also that the page on http://www.asisi.co.uk/or1kecos.html also seems to work with Cygwin (as obtained yesterday). I will update this and endeavour to get it onto the Opencores site soon.
