Hi all,

has anybody success using serial ports with Pharo on Mac or Linux? We're having reports of lack of success, including lack of success in recompiling a Pharo VM with a correct serial port access (a few months ago), where the same approach was sucessfull with a squeak VM.

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
