2003-01-28Stefan Allius noticed dlib_pic.o was not using XXFLAGS as it shouldEric Andersen
2003-01-24Support having libs in /usr/X11R6/lib by default as wellEric Andersen
2003-01-24Ok, people are probably going to hate me for this... This commit changes theEric Andersen
type of 'struct stat' and 'struct stat64' so they use consistant types. This change is the result of a bug I found while trying to use GNU tar. The problem was caused by our using kernel types within struct stat and trying to directly compare these values with standard types. Trying an 'if (a < b)' when 'a' is an 'unsigned long' and 'b' is an 'int' leads to very different results then when comparing entities of the same type (i.e. time_t values).... Grumble. Nasty stuff, but I'm glad I got this out of the way now. As a result of this fix, uClibc 0.9.17 will not be binary compatible with earlier releases. I have always warned people this can and will happen. -Erik
2003-01-03If they call dlopen with anything other than RTLD_LAZYEric Andersen
or RTLD_NOW then we need to error out.
2002-12-12Rework things such that staticly linked applications can useEric Andersen
dlopen and have it be successful. This required moving some things out of ldso.c into readelflib1.c, and directly including hash.c and readelflib1.c into dlib.c when building the static version of the library. -Erik
2002-12-04Change some variable names so we are more consistant with whatEric Andersen
the linux kernel uses. -Erik
2002-12-04Looks like this is in fact needed to properly debug dynamicallyEric Andersen
linked stuff, so put it back but add a check for NULL
2002-12-01Make ldd work even more like GNU ldd by appending dummy load addressesDavid Schleef
2002-11-28Kill a bit of unused cruftEric Andersen
2002-11-22Ok... here's the summary:Manuel Novoa III
Hopefully locale support will build when cross compiling now. Collation is still not supported, but that's what I'm currently working on. In the next couple of days, I'll probably put up a couple of files for download that will save people the trouble of generating all the glibc locales. Added *wprintf functions, although they currently don't support floating point. That will be fixed when I rewrite _dtostr... or possibly before. Added the wcsto{inttype} functions. Added iconv() and a mini iconv utility. The require locale support and only provide for conversions involving the various unicode encodings { UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built with the locale data, and the internal WCHAR_T.
2002-11-21Act more like the GNU version. Accept multiple args. Accept/ignoreEric Andersen
the "--" option since we always do that anyways. -Erik
2002-11-20Kill SVR4_BUGCOMPATEric Andersen
2002-11-20Patch from Stefan Allius:Eric Andersen
- Invert all FORCE_SHAREABLE_TEXT_SEGMENTS checks. - Define FORCE_SHAREABLE_TEXT_SEGMENTS in the Makefile, so it can be configured by the config system. - linuxelf.h inspects that we don't combine FORCE_SHAREABLE_TEXT_SEGMENTS and SVR4_BUGCOMPAT - Add a new config option for FORCE_SHAREABLE_TEXT_SEGMENTS
2002-11-19Per suggestion from Stefan Allius, change DO_MPROTECT_HACKS toEric Andersen
the more clear FORCE_SHAREABLE_TEXT_SEGMENTS.
2002-11-19Stefan Allius writes:Eric Andersen
I fixed two little bugs in ldso.c: - For LDD support we test the old environment variable LD_TRACE_LOADED_OBJECTS. - Before we init the GOT table of the dynamic loader we have to check, if we have a DT_PLTGOT entry. If DT_PLTGOT was zero we patch somthing in the header of the dynamic loader. This was the cause, why we have to enable the DO_MPROTECT_HACKS option for all targets, to avoid segment faults. In readelflib1.c I added a warning, if we try to load a shared library, which wasn't compiled with -fPIC or -fpic. So if we disable the DO_MPROTECT_HACKS option we are sure, that we don't waste memory by shared libraries which aren't able to share their text segment. I think this is a helpful option on little embedded systems.
2002-11-15For now, revert Ronald Wahl's change to dlopen. We need toEric Andersen
look into what is breaking dlclose() further... -Erik
2002-11-15Ronald Wahl writes:Eric Andersen
I noticed that dlclose() does not work since libraries loaded with dlopen are not marked as "loaded_file". This breaks apache with dynamic modules. I append a small fix against uClibc-0.9.16.

2002-11-12A powerpc patch from Ronald Wahl:Eric Andersen
Ok, now i got it after a day of work. I have had a look into glibc and found the following: sysdeps/powerpc/dl-machine.c: ... case R_PPC_JMP_SLOT: /* It used to be that elf_machine_fixup_plt was used here, but that doesn't work when ld.so relocates itself for the second time. On the bright side, there's no need to worry about thread-safety here. */ { Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr; ... The comment made me suspicious. The same position in uClibc looks like this: ldso/ldso/powerpc/elfinterp.c: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = (unsigned long)_dl_linux_resolve; int delta = targ_addr - (unsigned long)reloc_addr; ... When I change it to the following it works: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = *reloc_addr; int delta = targ_addr - (unsigned long)reloc_addr; ... I hope it will not break anything. Can anyone review this change and commit it into CVS? thanks, ron
2002-11-08Patch from Stefan Allius for libgcc multilib supportEric Andersen
this is the last patch, we need to make the support of multitarget libgcc complete. --------------------------------- In ldso/ldso/Makefile I added the CPU_LDFLAGS-y to the LDFLAGS --------------------------------- In libc/Makefile I set the LDFLAGS for the script get-needed-objects.sh with CPU_LDFLAGS-y --------------------------------- In extra/scripts/get-needed-object.sh we now use the LIBGCC from Rules.mak and call LD with LDFLAGS (==CPU_LDFLAGS-y). Addtionally I grep the NM output, to fix the unresolved external __GLOBAL_OFFSET_TABLE__ on SuperH targets. ---------------------------------

-Erik
2002-10-31Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen
been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. I have thus far updated only x86. I'll be updating the other architectures shortly. -Erik

2002-10-15Fixed 'dlopen' call for MIPS. Things seem to work swimingly. Woohoo!"Steven J. Hill"
2002-10-01This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen
how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips.
