These patches should really go to the serialice mailing list (serialice@serialice.com). That said, hopefully the second half of that patch fixes the seqfaults I'm seeing when trying to use SerialICE ;)
My apologies, I had searched the coreboot list and saw several posts regarding serialice and (erroneously) jumped to the conclusion that this was the right spot.
Re-posting original message to the serialice list:
I tried the instructions for getting serialICE installed, but ran into two problems (patch attached solved both problems):
1) the configure script failed to detect lua, fixed by adding --extra-ldflags="-lm" to the build.sh file. The output of the lua test (with redirect to dev/null removed) is below: sh build.sh /usr/local/lib/liblua.a(lvm.o): In function `.L112': lvm.c:(.text+0xb18): undefined reference to `pow' /usr/local/lib/liblua.a(lvm.o): In function `.L177': lvm.c:(.text+0x232d): undefined reference to `pow' /usr/local/lib/liblua.a(lcode.o): In function `.L211': lcode.c:(.text+0x1453): undefined reference to `pow' collect2: ld returned 1 exit status Package lua was not found in the pkg-config search path. Perhaps you should add the directory containing `lua.pc' to the PKG_CONFIG_PATH environment variable No package 'lua' found Package lua was not found in the pkg-config search path. Perhaps you should add the directory containing `lua.pc' to the PKG_CONFIG_PATH environment variable No package 'lua' found
Error LUA not found, can't build with SerialICE support.
2) QEMU seg faulted when checking for kqemu enabled (note that I am running 0.11.1, but I had same behaviour on the qemu 0.11.0 which is checked into the SerialICE v1.5 tag). I'm guessing it is something with my Gentoo install that causes the seg fault but if kqemu is not needed for serial ice then maybe it is easier to remove it.:

The following patch fixed both my problems:
Disable kqemu since it caused a seg fault and is not needed.
Add libm to the LDFLAGS to make the lua test work.
