The build was failing, because rts/OSThreads.h via Rts.h from libraries/bytestring/cbits/is-valid-utf8.c had no definition of `clockid_t`. This type is not exposed with _POSIX_C_SOURCE is not defined to a sufficiently high value:
SYNOPSIS #include <time.h> int clock_getres(clockid_t clockid, struct timespec *res); int clock_gettime(clockid_t clockid, struct timespec *tp); int clock_settime(clockid_t clockid, const struct timespec *tp); Link with -lrt (only for glibc versions before 2.17). Feature Test Macro Requirements for glibc (see feature_test_macros(7)): clock_getres(), clock_gettime(), clock_settime(): _POSIX_C_SOURCE >= 199309L I quick-and-dirty work-around was: --- a/libraries/bytestring/cbits/is-valid-utf8.c +++ b/libraries/bytestring/cbits/is-valid-utf8.c @@ -27,6 +27,10 @@ LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. */ +#undef _POSIX_C_SOURCE +#define _POSIX_C_SOURCE 200809L +#undef _XOPEN_SOURCE +#define _XOPEN_SOURCE 700 #pragma GCC push_options #pragma GCC optimize("-O2") #include <stdbool.h> There's surely a better solution. -- Viktor. _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
