make all failing

[khemkasudeep]

Hi

I am trying to build dtrace.
I have installed libdwarf and elfutils-libs
make all is failing with below error -
Any idea what may be going wrong.

I just tried on the latest arch linux with libdwarf installed as well, and getting the same error

I'm having the same issue. Looks like the issue is the undefined reference to dwarf_loclist. Any ideas?

This seems to be related to Changes to support CentOS 7:

The script seems check if libdw OR libdwarf should be linked. But on current Arch Linux setups dwarf_begin and dwarf_loclist are not defined in the same SO:

juergen@samson:/usr/lib → nm -D libdw.so|egrep '(dwarf_begin|dwarf_loclist)$'
0000000000009f80 T dwarf_begin
juergen@samson:/usr/lib → nm -D libdwarf.so|egrep '(dwarf_begin|dwarf_loclist)$'
0000000000029f70 T dwarf_loclist

[juergenhoetzel]

The same error occurs on a Centos7 system

tools/mkport.pl
/tmp/ccfGMqi0.o: In function `main':
juergen.dwarf.c:(.text+0x1f): undefined reference to `dwarf_loclist'
collect2: error: ld returned 1 exit status

but builds continues successfully

Have the same problem on Void Linux Kernel 5.8.16_1
