Is there a test in configure script to set the CPL_LSB macro automatically?
I am building on both big and little endian and I am not seeing the
macro being set
CPL_IS_LSB is not being set to either 0 or 1
thanks
Jared,
The AC_C_BIGENDIAN step in configure sets the WORDS_BIGENDIAN macro (or not)
in cpl_config.h. cpl_port.h then checks for this to decide whether to set
CPL_LSB or CPL_MSB and how to set CPL_IS_LSB.
The following code in cpl_port.h should ensure that anything including
cpl_port.h gets a 1 or 0 definition of CPL_IS_LSB. Note that there are
some files (such as sublibraries such as libtiff or libpng) that do not
include cpl_port.h.
#if defined(CPL_LSB)
# define CPL_IS_LSB 1
#else
# define CPL_IS_LSB 0
#endif
Best regards,
