[edit] Installing SDCC on OpenBSD 6.0

As of OpenBSD 6.0 (released 2016), SDCC 2.8.0 (released 2008) is included in the OpenBSD packages.

To use a more current SDCC, such as 3.6.0 on OpenBSD it will have to be built from source:

  • Get the source of the desired SDCC version, e.g. download and unpack a release tarball or checkout from svn.
  • Configure via
CXXFLAGS=-I/usr/local/include ./configure --disable-pic14-port --disable-pic16-port

This will complain about any missing dependencies. If that happens, install the dependency, and try configure again. The CXXFLAGS is necessary to find the boost headers, since /usr/local/include is not in the default include path for OpenBSD. The dependencies of the pic ports are hard to satisfy on OpenBSD; the easiest way aroaund is to just disable building of those ports.

  • Build via
MAKE=gmake gmake

gmake is not part of the default install and might have to be installed first. We need it since SDCC won't build with the OpenBSD make.

[edit] Using SDCC

SDCC uses more stack space than typical applications, and OpenBSD has a lower stack size limit than typical operating systems. The limit can be increased e.g. via

ulimit -s 32768
