[Vm-dev] VM Maker: CMakeVMMaker-EstebanLorenzano.191.mcz

[Nicolas Cellier]

Once I have the sources (generated or downloaded), I do
$ cd unixbuild/bld
$ ../../platforms/unix/config/configure --without-npsqueak CFLAGS="-g
-O2 -fno-caller-saves -Wall -Wextra -msse2 -D_GNU_SOURCE
-D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1
-DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread
$ make

Note that this is a virtual box

$ uname -a
Linux localhost 3.4.24-desktop586-3.mga2 #1 SMP Sat Jan 5 02:32:45 UTC

$ gcc --version
