xfont complie error

Postby Gablea » Apr 07, 2019 23:29

hi all,

I have just updated my windows PC to version 1.6 and I am now getting a build error (as below)

    Build error(s)

Any ideas what it means as in 1.5 it compiled with no problem what so ever and it ran fine.

In xfont.bi
changing the four properties to ulong stops the error.
(I have never has any luck with xfont since fb 24)
But it is worth a try.

lines 166 - 169

Code: Select all

Declare Property BackColor  () As ulong
        Declare Property BackColor  (ByVal Expression As ulong)
        Declare Property ForeColor  () As ulong
        Declare Property ForeColor  (ByVal Expression As ulong)

Thanks for the tip I shall try that when I get back to the office.

Did something change then between 1.5 and 1.6?

I see in the changelog ,
first line:
Name mangling of Integer/Long parameters was reversed on 32bit to match 64bit.
So, perhaps this could be a cause, but the experts will tell you exactly.
In the lib I see
00003250 T __ZN5XFONT9INTERFACE16BACKCOLOR__get__Ev@4
00003150 T __ZN5XFONT9INTERFACE16BACKCOLOR__set__Ej@8
Which correspond to the get set property in the .bi file in which the set no longer accepts uinteger but doesn't error at ulong.
Anyway you can fiddle around with the .bi file when you finish.
