This package uses autotools, so the usual ./configure && make is enough to build
the libraries. If cloning the bare sources the package needs to be bootstrapped
in advance with the autoreconf -vfi command. This step requires the xa cross-assembler
to compile the 6502 code, usually provided by distributions with the xa65 package
or available at http://www.floodgap.com/retrotech/xa/.
To enable full quality SID emulation libresidfp
is required.
In addition to the standard build options the following are available:
-
--enable-debug[=no/yes]: compile with debugging messages (disabled by default) -
--enable-testsuite=PATH_TO_TESTSUITE: add support for running VICE's testsuite (in PRG format). The testsuite is available in the repository. Intended only for regression tests since it may break normal code execution. The path to testsuite must include terminal path separator. (disabled by default) -
--enable-tests: enables unit tests. Usemake checkto launch the testsuite (disabled by default) -
--with-exsid: Build with exsid support. Requires either libexsid or one of libfdti1 or libftd2xx -
--with-usbsid: Build with usbsid support. Requires libusb
If doxygen is installed and detected by the configure script, the documentation
can be built by invoking make doc.
Known bugs/limitations:
- mus data embedded in psid file is not supported
- hashlib https://github.com/Cra3z/hashlib distributed under MIT license
