Hello all,
Recently, I tried to compile the unix source for racket-textual found
here:
http://download.racket-lang.org/racket-textual-5-2-1-src-unix-tgz.html
using GCC 4.7.1 and kernel Linux 3.4.4-3 x86_64.
cd src && ./configure=/opt && make returned the following errors:
In file included from ./newgc.c:2436:0,
from ./gc2.c:15:
./sighand.c:63:35: warning: ‘struct siginfo’ declared inside parameter
list [enabled by default]

declaration, which is probably not what you want [enabled by default]

make[4]: *** [gc2.o] Error 1
i opened src/racket/gc2/sighand.c and looked at the offending line 63,
where struct siginfo doesnt seem to be an actual struct. Scrolling down
a bit more to line 131, i see that siginfo_t is a valid typedef so on
line 63 i did s/struct siginfo/siginfo_t/ and the syntax errors
disappeared.
make && sudo make install then ran fine and I used the racket executable
to run a .rkt source file with no problems.
seems like a typedef might have been changed somewhere along the road?
