Re: Error on enum statement. Can sombody take a little time and explain the enum and the error?
Okay casting to value type did fix the error message. Should I commit
the fix to trunc?
@Shannon:
I could imagine it could be that my gcc version my dirstibution uses.
Someone said he is running into errors because of it.
My distribution compiles with: gcc (GCC) 6.2.1 20160830
However I do not find this a satisfactory explanation :)
All the best

Subject: Error on enum statement. Can sombody take a little time and

Hello all,
I tried to compile the source again. since I had again missing
definition on trunc I wanted to know if I can build at least the 4.1.3
release. I checked out the branch and started all over.
And I ran into following Issue:
../inc/basebmp/packedpixeliterator.hxx:80:10: error: enumerator value
for 'bit_mask' is not an integer constant
The corresponding code is:
enum {
/** The number of pixel within a single value_type value
*/
num_intraword_positions=sizeof(value_type)*8/bits_per_pixel,
/** Bit mask for one pixel (least significant bits)
*/
bit_mask=~(~0 << bits_per_pixel)
[orcmid]
Try a couple of things:
1. Put spaces in the "=~" to be something like " = ~" in the definition of
bit_mask.
2. If that makes no difference, try
bit_mask = ~ ((value_type)(~0 << bits_per_pixel))
and if that doesn't work, see if
bit_mask = ~ ((int)(~0 << bits_per_pixel))
or even
bit_mask = (int) (~(~0 << bits_per_pixel))
get the job done.
It seems strange for an enum being used this way. It is a clumsy way to define
two numeric constants that are not involved in an enumeration at all.
};
An explanation would be great. I found [1] on the net, but I am realy
unsure if this is the same. And I do not understand the code in
packedpixeliterator at all.
All the best and thanks for your time.

If this is the 4.1.3 source, it has been compiled many times. I would
look for a configuration problem affecting the the value of bits_per_pixel.
