I am trying to rejoin the development team but am having loads of
problems.

Latest is with liblo.   I have sources of 2019-02-28: Release 0.31
and it builds/installs apparently with no problem. But when I try to
build Csound I get

Looks like a version change?  Any ep welcome.  I am
missing the buzz from coding

==John ffitch

I have liblo 0.29 here, and it works. I think some lo types may have changed in 0.31
and your compiler is barfing at that. I made some changes that should help:

1) First error: 
I checked the header lo/lo_lowlevel.h and I have

uint32_t lo_blobsize(lo_blob b);

so I suppose the correct cast should be (lo_blob) not (lo_blob *)

I think the change may be in the type, in my lo/lo_types.h  I have

def void *lo_blob;

but your error says it’s struct lo_blob_ *

I changed this and it’s ok here still 

2) Second error:

I think if we change the signature of OSC_handler to

static int32_t OSC_handler(const char *path, const char *types,
                       lo_arg **argv, int32_t argc, lo_msg data, void *p)

that could fix it.  I changed it here and it’s ok.

I have committed these changes to the develop branch. Pull it and see if it works now.

Still fails to uild.
peraps #i soukd look for  0.29

Can you post the errors after the pull?

I have built and installed the latest here and Csound builds correctly, so I am thinking the version does not matter

I’ve noted something odd though. Your error message says

/usr/local/include/lo/lo_lowlevel.h:1065:10: note: expected ‘lo_blob {aka struct lo_blob_ *}’ but argument is of type ‘struct lo_blob_ **’
uint32_t lo_blobsize(lo_blob b);

But in my 0.31 installation that line does not have "uint32_t lo_blobsize(lo_blob b);”. I can’t reconcile your error message with the
0.31 sources.

I am wondering if you have two versions of liblo in your system?

I see the headers you are using are in /usr/local/include/

In my installation, they are /usr/local/lib/include.

I typed too soon.  The liblo part seems to work now.  To be replaced by parsing errors in booleans.  These were working earlier so not sure what is wrong. Probably time to give up for the night.
