Hi,
The problem arises when the mingw64 header winreg.h gets included.
We then get errors like:
C:/tmp64ng/c/include/projects.h:161:47: error: conflicting types for
'PVALUE'
typedef union { double f; int i; char *s; } PVALUE;
....
C:/tmp64ng/c/x86_64-w64-mingw32/include/winreg.h:75:3: note: previous
declaration of 'PVALUE' was here
__MINGW_TYPEDEF_AW(PVALUE)
^
The fairly simple (though tedious) workaround is, prior to building proj,
change each of the few occurrences of "PVALUE" in the proj source to a
symbol that doesn't clash.
(I've been using "_P_VALUE", but perhaps something like "PROJVALUE" is a
better choice .... I'm happy with *any* symbol that's not going to clash.)
Could the proj developers please rename "PVALUE" to something that doesn't
clash ?
I really would like to not have to alter the proj source in future proj
releases.
I did raise this matter a few years ago but, as nothing was ever done, I
thought that maybe I should instead submit a bug report along with a patch.
However, AFAICT, to submit a bug report I need to go to
http://www.osgeo.org/osgeo_userid/ and create a user id so that I can first
log in.
Unfortunately the link to "this simple form" (
https://www.osgeo.org/cgi-bin/ldap_create_user.py ) results in a "page can't
be displayed error" for me.
There's a suggestion there that this could be a problem with my browser
settings, though I don't usually have any trouble with secure connections.
Is there any other way I can create a user id ?
Cheers,
Rob
