Fix tst-dlsym-error build
|
||||
|
||||
This patch fixes the new test tst-dlsym-error build on aarch64
|
||||
(and possible other architectures as well) due missing strchrnul
|
||||
definition.
|
||||
|
||||
* elf/tst-dlsym-error.c: Include <string.h> for strchrnul.

|
||||
Report dlsym, dlvsym lookup errors using dlerror [BZ #19509]
|
||||
|
||||
* elf/dl-lookup.c (_dl_lookup_symbol_x): Report error even if
|
||||
skip_map != NULL.
|
||||
* elf/tst-dlsym-error.c: New file.
|
||||
* elf/Makefile (tests): Add tst-dlsym-error.
|
||||
(tst-dlsym-error): Link against libdl.
