Bug ID: 54795
           Summary: configure fails to find pcap development libraries
                    with libpcap <1.9.0 present
           Product: Wine
           Version: 8.2
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wpcap
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Hello,

In my case, Debian 8 "Jessie" ships libpcap 1.6.2.

According to the man page, pcap_init was introduced in libpcap 1.9.0.
https://man7.org/linux/man-pages/man3/pcap_init.3pcap.html

The ~regression~ commit modifies configure to check for pcap_init() in lieu of
pcap_create(), which fails on such old OS.

Regards.

pcap_init() is needed to make wpcap work with the new wow64 setup. I would
suggest building libpcap yourself if you really need it on Debian 8.

wpcap tests terminal output on Wine 8.7 under Debian 8 with custom libpcap

Hello,

I built libpcap and could build Wine 8.7 with it, but running the wpcap tests
fails.

I copied wpcap_test-stripped.exe in ~/.wine/drive_c and ran:
cd ~/.wine/drive_c
LD_LIBRARY_PATH="/usr/local/lib" wine wpcap_tests-stripped.exe

It says 'No pcap support, expect problems' and crashes.
Terminal output is attached.
The libpcap custom build is installed in the default destination /usr/local/
bin, lib, etc.

Regards.

Hello,

I tried LD_PRELOAD="/usr/local/lib/libpcap.so" wine wpcap_tests-stripped.exe

It says "ERROR: ld.so: object '/usr/local/lib/libpcap.so' from LD_PRELOAD
cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.".

So now I need to find how to have 32-bit libpcap library along the 64-bit one.

Regards.

Note that running the 32-bit test will require the new wow64 setup.
Alternatively you could try the 64-bit test.

Hello,

I tried the 64-bit test and it works, even without setting any LD_* variable.

So it means I could build Wine with pcap support and use the custom libpcap on
Debian 8.

Marking invalid.
