#78 SConstruct fails to find static build of QT

[Anonymous]

The SConstruct function CheckForQtAt (line 84) fails if QT is build statically only.

I'm trying to build Lprof statically on OS X - as a workaround I am making CheckForQtAt always return true.

Actually it is AttemptLinkWithVariables that is causing the trouble, I'm not sure where that comes from.

AttemptLinkWithVariables ends up calling DoWithVariables where it builds a command that looks like this when expanded:

context.TryLink(""
#include <qapplication.h>
int main(int argc, char **argv) {
QApplication qapp(argc, argv);
return 0;
}
"" , ".cpp")

context contains the location of Qt (IE. normally the same as QTDIR for most builds). Perhaps it has the wrong QTDIR when only statically linking? Just before the call to AttemptLinkWithVariables you can do

print QTDIR

to see what value it is using. If this is not the location of the static Qt installation (or a valid Qt installation) then the call to AttemptLinkWithVariables will fail.

This Qt checking code is borrowed from another project so I am far from an expert on how it works. But you may be trying to do something for which it will need to be modified to work.

Since you currently have a work around I will hold off doing anything with this until the other issues you are having are worked out.

Changed how this works. So it should no longer be an issue.
