Note that this still builds on sage.math with GCC-4.2.4... But it doesn't build on Skynet with newer GCC's.

Hi William,

Yes, it is just a question of a few extra includes. I haven't fixed it
since I was making a new release of Frobby anyway. That new release
has become rather large since that has been convenient for my
research, and so it is taking longer than expected. I'll submit a fix
once I get back from this conference next week.

Cheers

The error in the ticket mentions srand. What I do is google srand and I get e.g.

 http://www.cplusplus.com/reference/clibrary/cstdlib/srand/

it says it is in cstdlib, so add

 #include <cstdlib>

to the cpp file that is having a problem. Then likely another file
will have the same problem due to the same or another missing header,
and after a few iterations of this the problem should be solved. Most
likely all the missing includes are in cpp files, though it is
possible that a header might miss something too. The problem is caused
by older versions of GCC having header A also pull in header B without
the standard saying that it should do so (which is allowed but
unfortunate). The newer version of header A in a newer GCC then stops
pulling in header B, and suddenly it becomes apparent that header B
should have been included where A was also included, but before it was
invisible that this should have happened.

Cheers
Bjarke

Even with gcc-4.4.3, Frobby doesn't build.

If somebody doesn't post a new frobby spkg on this ticket for review this week, I'm moving the frobby spkg to "experimental".

I wish you would clarify in the developers handbook, or even just on sage-devel, what is the difference between "optional" and "experimental".

I have moved Frobby from optional to experimental. I'll move it back when this problem is addressed.

I've had some problems on this because I don't have access to a computer that both has Sage on it and that at the same time has a recent enough version of GCC that this issue comes up. What I've done is patch the spkg so that the Frobby code in it compiles on a Cygwin machine I've got, and then I've tested that it still installs on sage.math, which I've recently gotten access to. So if we are lucky this will work, though someone with both Sage and a recent version of gcc should check it. I put the spkg here:

​http://sage.math.washington.edu/home/bjarke/frobby-0.7.6.p1.spkg

I looked at this for 1 minute:

(1) There are some tmp ~ files laying around

wstein@sage:~/tmp/frobby-0.7.6.p1$ ls
patches  spkg-check  spkg-install  spkg-install~  SPKG.txt  SPKG.txt~  src
wstein@sage:~/tmp/frobby-0.7.6.p1$ rm *~

(2) The hg repo has lots of files that have been added but not checked in:

wstein@sage:~/tmp/frobby-0.7.6.p1$ ls
patches  spkg-check  spkg-install  SPKG.txt  src
wstein@sage:~/tmp/frobby-0.7.6.p1$ hg status

(3) I don't understand why *upstream* -- i.e., the *author* of frobby-- is adding a ton of patches to his own code. Why not just fix the src/ directly?

[was]

That said, Frobby *does* build with GCC-4.5.0, which is great news!!

if [ -f bin/release/frobby.exe ]; then \
          mv -f bin/release/frobby.exe bin/release/frobby; \
        fi
strip bin/release/frobby
cd bin; rm -f frobby; link ../bin/release/frobby frobby; cd ..

(Oops, I put my response as the description. Now fixed.)

Thanks for the prompt review. I committed the outstanding files in the repository and removed the two ~ files. The result is up in the same place:

​http://sage.math.washington.edu/home/bjarke/frobby-0.7.6.p1.spkg

I'm adding patches rather than edit src/ because as I understand it the code in src/ must be an official release of the upstream code. No version 0.7.6 of Frobby exists that compiles under gcc 4.3.0, and I'd rather add some patches here than make an official release of an old version.
