==Compiling Bochs from Source== |
|||
Bochs has many compile-time configuration options, some of which conflict, and therefore a binary distribution of Bochs may not be suitable for your purposes. I found it was best to compile my own copy of Bochs to be sure I had the features that I needed. Also, you should consider using the CVS snapshot version of Bochs if the released version is old and not working for you. I found this was necessary up until version 2.4 was released, for example. |
|||
The array of Bochs configuration options can be confusing, and you cannot assume the defaults are going to be sensible. These are the options I use, this can get you started: |
|||
./configure --enable-smp \ |
|||
--enable-cpu-level=6 \ |
|||
--enable-acpi \ |
|||
--enable-all-optimizations \ |
|||
--enable-x86-64 \ |
|||
--enable-pci \ |
|||
--enable-apic \ |
|||
--enable-vmx \ |
|||
--enable-pae \ |
|||
--enable-large-pages \ |
|||
--enable-debugger \ |
|||
--enable-disasm \ |
|||
--enable-debugger-gui \ |
|||
--enable-logging \ |
|||
--enable-vbe \ |
|||
--enable-fpu \ |
|||
--enable-mmx \ |
|||
--enable-3dnow \ |
|||
--enable-sb16=dummy \ |
|||
--enable-sep \ |
|||
--enable-x86-debugger \ |
|||
--enable-iodebug \ |
|||
--disable-plugins \ |
|||
--disable-docbook \ |
|||
--with-x --with-x11 --with-term |
|||
A few notes: |
|||
* Bochs has GDB-stub support, and its own internal debugger. These cannot be compiled into the same Bochs binary. |
|||
* The GDB-stub in Bochs does not support SMP, last time I checked. |
|||
* If you do not enable PCI, then the Intel Multiprocessing tables will not appear in memory. |
|||
* I was unable to successfully load the GUI debugger without specifying <tt>--disable-plugins</tt>. Otherwise, I get dynamic loading symbol errors. |
