Hmmm Solaris :)

Sorry I'm not familiar with Solaris and we currently have too few resources to seriously support it.

In any case, we only support gcc at the moment. I suggest trying compiling with that.

See 0004121 for another issue on Solaris (10) -- which also happens to show how to use gcc by the way. Hopefully that issue is not an issue on Solaris 11, I don't know, let us know.

It used to work at one point.. and I don't think we added any incompatible code since then.. so it's probably something easy.

>> we currently have too few resources to seriously support it

you can get solaris and the studio for free from sun, eh, i mean oracle ;-)
a small vm is installed in less than 10 minutes and letting it run there every once in a while takes even less time. if something shows up it could be a quick fix and an improvement for the code as well. if not then no harm done either.


>> we only support gcc at the moment

as pretty much any other project these days. a pity tho because not only that gcc has never been known for great results it also gives a much better view at the program and so far unnoticed potential issues when running it through a serious compiler.


>> Hopefully that issue is not an issue on Solaris 11

it's not. a gcc build was successful.

seems i found a solution here. basically the sun compiler doesn't allow mixing static and inline functions. there're 2 solutions for that:
1. remove inline
2. use option -features=no%extinl

the docs say:
Compile new codes with -features=no%extinl to obtain the same treatment of extern inline functions as provided by older versions of the C and C++ compilers.
http://docs.oracle.com/cd/E24457_01/html/E21990/bjapr.html#bjaqo

then the oracle compiler is not C99-compliant.

'static' defines a symbol as having internal linkage (similar to visibility 'hidden', which is a GNU-ism).

GNU C is the correct interpretation of C99 here...

 did you check the second link?

EDIT: anyway there're 2 more things to get it done properly using suncc:
1. option -features=extensions to avoid problems with anonymous structures, and
2. there're 2 versions of install available. the native one /usr/sbin/install doesn't work with the Makefile so in case that has been found first and added to the Makefile replace it with /usr/gnu/bin/install

I did check the link. The oracle compiler is not C99-compliant.

Both 'static' and 'inline' define a translation unit as having internal linkage.

Beyond that, anonymous structures are a valid feature in both C99 and C11.

my bad, it was anonymous structures with union(s).

anyway this seems solved for now :-)
