| | | | | | | | | | | this was sent earlier in a different form: http://www.uclibc.org/lists/uclibc/2004-January/008136.html find attached a smaller version ... perhaps adding a fprintf to stderr before calling abort would be nice like in the glibc patch, but whatever glibc has since adopted a similar fix for their malloc (third hunk, line 1970) http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/malloc/malloc.c.diff?r1=1.121&r2=1.122&cvsroot=glibc&f=h -mike

| | | | | | | | | | | | i sent this earlier but perhaps people missed it the first time around :) http://www.uclibc.org/lists/uclibc/2004-August/009544.html basically if you try to #include <sys/ucontext.h> on arm it'll fail because ucontext.h utilizes typedefs found in bits/sigcontext.h ... i386 already has this fix in uClibc find attached a trivial patch to fix this -mike

| | | | | | | | | | | | | | Hi Manuel & Erik I think I know why MIPS is broken. _dl_perform_mips_global_got_relocations() is broken. It will due to my latest changes reloctate ldso. This function needs to die and its job should be done inside _dl_parse_relocation_information(). It is mostly a copy and paste job, Also PERFORM_BOOTSTRAP_GOT and PERFORM_BOOTSTRAP_RELOCATION should be fixed, they use symbols which aren't passed as arguments. Jocke
* Patch by Carl SHAW <carl.shaw@st.com>...Manuel Novoa III2004-08-252-1/+107
| | | | | | | | | | | | Below is a patch to make the pread and pwrite calls work on the SH architecture. I've only tested this on the SH4 with a 2.4.24 kernel - a fairly recent kernel is required as the problem is partially fixed in the kernel itself. For more information (in relation to glibc, but the problem is the same) see the thread at http://sourceforge.net/mailarchive/message.php?msg_id=2375908 Someone should really test this on the SH2/3...

| | | | | | | | | | | | | | | | | I finally tracked down the problem with SH4 shared library loading - in file ldso/ldso/sh/dl-startup.h, the line #define DL_BOOT(X) static void __attribute_used__ _dl_boot2 (X) should be #define DL_BOOT(X) static void* __attribute_used__ _dl_boot2 (X) otherwise the application code will never be called and _dl_boot will just return causing a segmentation fault.

| | | | | | | | | | | "There's a bug in the SH asm, it calls into 'C' code without preserving all the important scratch registers. I have been meaning to double check the changes as I think more registers need to be saved, then I was going to send it back to uClibc. From the sound of it this isn't your problem, but you never know. Attached is the patch as it stands for the loader on SH." Glibc appears to do the same.

| | | | | | | | | | | | | | | | i was sticking some libraries in non-standard (i.e. not-hardcoded) paths and then updating ld.so.conf accordingly ... oddly though, i couldnt get binaries that linked against those libraries to run ... `ldconfig -v` showed the required libraries being detected/cached, so something seemed wrong ... turns out the libraries were being tagged as LIB_ELF_LIBC0 in the cache and the loader currently only accepts LIB_ELF_LIBC{5,6} ... since readsoname.c in ldconfig defines needed_tab with the mapping 'libc.so.0' -> LIB_ELF_LIBC0 it seems like the loader should accept this type too find attached a small patch which adds LIB_ELF_LIBC0 along side LIB_ELF_LIBC{5,6} as an accepted lib type in the loader when dealing with the ld.so.cache file

| | | | | | | | | | | | | | | | | in libdl, the XXFLAGS is set incorrectly if DODEBUG=y ... it has 'I.' added to it instead of '-I.' ... this of course pisses of gcc :) find attached a patch that cleans up the XXFLAGS setting so as to minimize this kind of thing ... when asked, mjn3 said it was a kosher idea ;) and later writes: hmm it seems ldso also utilizes USE_CACHE in the code (but LIBRARY_CACHE never propogates down to the Makefiles) so the fix is to add $(LIBRARY_CACHE) while setting $(XXFLAGS) Applied with minor fixes and also fixed up ldso/Makefile to match libdl/Makefile.
