[Vm-dev] attempting to build BochsX64Plugin on 32-bit Ubuntu

Sun Oct 25 03:54:18 UTC 2015

Hi Rob,

    I've only tried to build it in Mac OS X.  I've also changed the build structure so one /can/ build it either in 32 or 64 bits.  So look at the structure for building the support libraries under build.macos32x86 and replicate it under build.linux32x86, write or change platforms/unix/plugins/BochsX64Plugin/Makefile to pick up the libraries from (IIRC) build.linux32x86/bochsx64/{cpu/libcpu.a,disasm/libdisasm.a,fpu/libfpu.a} and you should be fine.  You'll need to run build.linux32x86/bochsx64/conf.COG which you'll copy from build.macos32x86/bochsx64/conf.COG
