| Summary | 0000652: rev 12223 breaks g++: undefined reference to `dl_iterate_phdr' | ||||||||
| Description |
SVN revision 12223 breaks the g++ compiler; now, I get: | $ echo 'int main() { }' >bar.cc | $ g++ bar.cc | /usr/lib/gcc/arm-xscale-linux-uclibc/4.0.2/libgcc_s.so: undefined reference to `dl_iterate_phdr' Going back to revision 12211 of toolchain/gcc/4.0.2/100-uclibc-conf.patch makes g++ work again. |

looks more like your toolchain is broken libgcc_s.so should be linked against libc.so which should be linked against ld-uClibc.so which contains the dl_iterate_phdr symbol |
|

ok, then it's an 'uClibc' bug. ld-uClibc.so does not contain this symbol. The code | #ifdef __USE_GNU | #if ! defined LIBDL || (! defined PIC && ! defined __PIC__) | int | __dl_iterate_phdr (int (*callback) (struct dl_phdr_info *info, size_t size, void *data), void *data) in uClibc-0.9.28/ldso/ldso/dl-elf.c gets never be evaluated because '__USE_GNU' is not defined. |

Correction: the static 'libdl.a' contains this symbol because in ldso/libdl/libdl.c the '__USE_GNU' macro will be defined. But this does not happen in ldso/ldso/ |

this has been fixed in uClibc head already, search the uClibc mailing lists for a patch for 0.9.28 if you wish to use that version |
