[Chicken-users] Compiling with --std=c99 supported?
Hi there, I came across something I think might be a bug. While I don't have a deep understanding of what c99 and gnu99 really mean, I noted that this happens on my 64bit system: $ chicken -version (c) 2008-2013, The Chicken Team (c) 2000-2007, Felix L. Winkelmann Version 4.8.0.4 (stability/4.8.0) (rev 578619b) linux-unix-gnu-x86-64 [ 64bit manyargs dload ptables ] compiled 2013-07-15 on aeryn.xorinia.dim (Darwin) $ cat c99test.scm (print hi) $ # gnu99 works: $ csc -C --std=gnu99 c99test.scm ./c99test hi $ # c99 does not work: $ csc -C --std=c99 c99test.scm ./c99test In file included from c99test.c:11:0: /usr/include/chicken/chicken.h:1532:1: error: unknown type name ‘sigjmp_buf’ C_varextern C_TLS sigjmp_buf C_restart; ^ Error: shell command terminated with non-zero exit status 256: gcc c99test.c -o c99test.o -c -fno-strict-aliasing -fwrapv -DHAVE_CHICKEN_CONFIG_H -DC_ENABLE_PTABLES -Os -fomit-frame-pointer --std=c99 -I/usr/include/chicken Is chicken supposed to be compilable with c99?

I'm afraid those options are like the retarded -ansi option, which utterly disables any POSIX extensions, accepting only vanilla ANSI C code. And indeed, the docs for -ansi say in C mode, this is equivalent to --std=c90. IIRC, the way to make this work again is to selectively re-enable POSIX extensions by passing some flags like -DPOSIX and such. If you can, try to avoid these options unless you're prepared to dig deep into compatibility differences.

Ok, I will rewrite my C-code so I don't have to use either of those flags. Thanks Peter! K.
