            Bug ID: 24815
           Summary: ld fails to find symbols from DT_NEEDED entries
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: ismael at linux dot com
  Target Milestone: ---

The system I'm having problems with is a musl-libc based system; I've an almost
identical system with glibc which works fine.

$ echo 'int main(){return 0;}' > test.c
$ gcc -c test.c
$ gcc test.o -lxml2 -fuse-ld=gold
$ gcc test.o -lxml2 -llzma
$ gcc test.o -lxml2
/usr/bin/ld:
/usr/lib/gcc/x86_64-pc-linux-musl/9.1.0/../../../../lib/libxml2.so: unde
fined reference to `lzma_properties_decode@XZ_5.0'
/usr/bin/ld:
/usr/lib/gcc/x86_64-pc-linux-musl/9.1.0/../../../../lib/libxml2.so: unde
fined reference to `lzma_code@XZ_5.0'
/usr/bin/ld:
/usr/lib/gcc/x86_64-pc-linux-musl/9.1.0/../../../../lib/libxml2.so: unde
fined reference to `lzma_auto_decoder@XZ_5.0'
/usr/bin/ld:
/usr/lib/gcc/x86_64-pc-linux-musl/9.1.0/../../../../lib/libxml2.so: unde
fined reference to `lzma_end@XZ_5.0'
collect2: error: ld returned 1 exit status
$ readelf -d /usr/lib/libxml2.so|grep lzma
 0x0000000000000001 (NEEDED)             Shared library: [liblzma.so.5]
$ ldd /usr/lib/liblzma.so.5
        ldd (0x7f6bc784b000)
        libc.so => ldd (0x7f6bc784b000)

Files liked with all libraries specified on the command line work fine; I'm
guessing something on the binutils build is different.
