Hello
I'm embarking on my first attempt to cross-compile something for riscos.
I have the environment all set up and figured out how to make the
project, but i'm not sure what the appropriate fix is for an issue:
The project in question (https://github.com/google/benchmark) runs a
check at build time to see which regex engine is available (std::regix,
posix regex, or gnu posix regex). It does this by compiling some test
programs and seeing which succeeds. The issue is that none do for riscos
(yet).
The closest I get is with the posix regex version, which includes
`regex.h`. This fails with the error:
$ $CXX posix_regex.cpp
In file included from posix_regex.cpp:1:0:
/home/dominic/gccsdk/cross/lib/gcc/arm-unknown-riscos/4.7.4/../../../../arm-unknown-riscos/include/regex.h:56:2:
error: 'size_t' does not name a type
I believe I could fix this by including <sys/types.h> in the crosslib's
regex.h (linux does this
https://code.woboq.org/linux/include/regex.h.html#23) but is this
appropriate? It seems like the right fix to me as regex.h shouldn't be
using types that haven't been declared.
Would this change be acceptable?
It does sound like regex.h should be including sys/types.h. If you make
this change locally in your environment, does the project build? If so,
then I will commit it.
Thanks,
Lee.
