libpcap fails to build with 14.07-rc3 SDK

[ewald.wasscher@…]

When I attempt to build the 14.07-rc3 libpcap package with the SDK for OpenWRT 14.07-rc3 x86/alix the build fails with the following errors:

Steps to reproduce:

• Unpack SDK
• Copy over libpcap directory from buildroot package directory
• make package/libpcap/clean
• make package/libpcap/compile
• make package/libpcap/compile V=s

Workaround:

• Create a symlink from $STAGING_DIR to /BB/build/x86/alix2/staging_dir

please try applying this patch on top of the unpacked SDK directory and test if it fixes the issue: ​http://nbd.name/bison-test.patch

bison -y -p pcap_ -d grammar.y
bison: /share/bison/m4sugar/m4sugar.m4: cannot open: No such file or directory

Apparently $STAGING_DIR_HOST isn't set by the Makefiles.

When I manually set STAGING_DIR_HOST on the shell the next error occurs:

./runlex.sh flex -Ppcap_ -oscanner.c scanner.l
flex: fatal internal error, exec of /BB/build/x86/alix2/staging_dir/host/bin/m4 failed

Hmz, something went wrong while adding the comment.

Applying the patch leads to:

new patch, same url, please test (revert the last one).

That helps, thanks!
