I think there might be a <string.h> in FL sources somehow, which is the wrong one or something like that. I saw that happen with a <math.h> before (which was a hard one to trace actually). Someone had reported similar problems with c headers apparently missing, when building with FLTK in one of the csound lists (and no one had a clue why). A student came to me with a similar error and after banging our heads on the wall we discovered a spurious math.h in FL/.

Do a search for string.h  in your filesystem. You should not have more than one. If there are duplicates, this may be the problem.

Ok, this is really weird. Things were compiling fine. I made an upgrade to FLTK 1.1.10 and then things were broken. But what's weirder is that I downgraded then things were really not working. So, now I can't compile Csound-CVS anymore....(other things seem unaffected)

'#include <string.h>' is missing in many of the files where string functions like 'memset' are declared, and I get lots of warnings about 'incompatible implicit declarations of built-in functions', but then how to explain why I *could* compile before? I suppose <string.h> is included in other files which are included, but grepping the H directory for references to <string.h> brings up only 2 files.....is my system somehow broken? But why can I compile other packages?

Interestingly, I tried adding '#include <string.h> to a few sample files, like auxfd.c, and ran their relevant compile lines by cut/paste.....no joy.....as if the addition of the include were invisible!!! What's going on in my system? I hate C/C++. So bloody impossible to untangle sometimes.

I did a major upgrade later on in the day of my whole system in Arch Linux. Still no joy. I wonder if there is something incompatible in versions, like I'm using a 'too bleeding edge system' now compared to the devs. Here's some relevant info, what I'm using now:

gcc version 4.5.0 20100610 (prerelease) (GCC)
gcc-libs 4.5.0-6
glibc 2.12-4
fltk 1.1.10-1

If anyone can help ( a C/C++ guru especially), I'd be most appreciative. Help me if you can, I'm feeling down....and I do appreciate yer being 'round!
