I see that the current out of the box build gives:

buildUnix32
CogNativeBoostPlugin setTargetPlatform: #Linux32PlatformId.
 PharoUnixConfig new
"generateForDebug;"
 addExternalPlugins: #( FT2Plugin SqueakSSLPlugin );
addInternalPlugins: #( UnixOSProcessPlugin  );
addThirdpartyLibraries: #(
 'libssh2'
'libgit2' );
generateSources;
 generate.

So, there is no SerialPlugin in there for sure.

platforms/unix/plugins/SerialPlugin has the unix specific code with the
primitives implementation.

It looks like the code uses those to access the serial ports.

#ifdef BUILD_FOR_OSX
static const char *serialPortBaseNameDefault = "/dev/ttys%d";
#else
static const char *serialPortBaseNameDefault = "/dev/ttyS%d";
#endif

and the SerialPlugin code inside the image looks okay.

Changing the buildUnix32 into:

buildUnix32
CogNativeBoostPlugin setTargetPlatform: #Linux32PlatformId.
 PharoUnixConfig new
"generateForDebug;"
 addExternalPlugins: #( FT2Plugin SqueakSSLPlugin );
addInternalPlugins: #( UnixOSProcessPlugin SerialPlugin );
 addThirdpartyLibraries: #(
'libssh2'
'libgit2' );
 generateSources;
generate.

generates all without an issue.

Now, I am going to compile this on CentOS and get back to you.

Phil
