Hi Ben,

 

Sorry I didn't get a chance to test 2.0.13 before it was released.

 

I've now tested 2.0.99, which I understand is a development version of what will become 2.1.0.

 

It also does not build on win32-x86, but with a different error.

 

Here are the errors and warnings on win32-x86:

I have a couple of other comments.

 

- 2.1.0 will require the utility program re2c.  I was able to install this on Linux with “yum”.  On Windows it is just a .zip file containing only a re2c.exe, which I just put somewhere in my PATH.  Is this utility available for all EPICS supported hosts?  The last release of re2c was 3 years ago.  Will it continue to be well supported?  It would certainly be nicer if the lexical tools provided in EPICS base could be used, rather than requiring another utility.

 

- Your documentation says: “Please respect the coding style when making changes. This includes indentation (tabs or spaces, how many) and all the other little things on which programmers like to differ ;-) like placement of braces etc. Note that for historical reasons the style differs somewhat between subdirectories. It is much easier for me to review patches if they do not contain gratuitous changes or combine several unrelated changes in a single patch.”

 

I completely understand what you are saying here.  However, one of the things that Eric Norum did post 2.0.12 was to convert all hard tabs to spaces in the files.  2.0.99 still has hard tabs in many files.  All C and C++ style guides I’ve read recommend strongly against hard tabs.  They make the files difficult to edit, because the default tab spacing is editor dependent, etc.  It would be nice to get rid of hard tabs if possible.

 

Thanks for all the work on this.

 

Cheers,

Mark

Hi Mark

Sorry for that. Note that I am *not* able to test nor build on all supported

platforms. Which is why I sent out two release candidates and waited more than

a week for people to report problems like that *before* making the release.

I became aware of the subversion repository at APS only after I had already

made extensive changes based on the released 2.0.12. This is why I had to

(manually) merge the changes in the APS repo after 2.0.12 into my development

branch. I tried to merge *those* changes back into 2.0.13 but I must have

overlooked this one. Note that I never expected to continue development of the

old 2.0.12 branch and that releasing 2.0.13 is purely a stop-gap measure

because the work on 2.1.0 took a lot more time than I originally expected.

This relates to printf warnings and is fixed in 2.0.13 since I can compile on

64 bit linux w/o getting such warnings.

This change is in 2.0.13.

This change is in 2.0.13.

This change is irrelevant as I don't use svn.

Same.

I was already done ansificating everything in the compiler when I became aware

of this change, so I ignored it. This is the only change amnong teh ones you

listed that touches src/snc/snc_lex.l, and indeed addition of the #include

<osiUnistd.h> line has been hiding here. I'll fix this, but it means I have to

make a 2.0.14 release.

This is also fixed in 2.0.13.
