I've just noticed Chris's announcement a few days ago of a new version,
and have reinstalled as suggested.
0 The JQT terminal screen is still taking its time to appear, apparently
around 60sec +- 15.
1 Please note that before this reinstallation, either running
install'qtide' in console or running the updatejqt shortcut (new in
j802) produced error messages ; I forget their exact content, but they
were on the lines of "unable to connect" or "unexplained connection
problems" or the like. It would be helpful if the error messages could
indicate version incompatibility or something along those lines, always
assuming that it is detectable!
2 Bill Lam had asked me to run shader under qtdemo, so I've had another
go with this new install.
shader does run on the first invocation without producing an error box,
although the resulting window is filled with vibrating black -
presumably rapidly repainting or alternating with white or the like -
it's not clear.
Here is the rather voluble output following that first firing:
GL_VERSION: 4.0.0 - Build 10.18.10.3304
GL_VENDOR: Intel
GL_RENDERER: Intel(R) HD Graphics 4000
GL_SHADING_LANGUAGE_VERSION: 4.00 - Build 10.18.10.3304
#version 400
in vec3 vertex;
in vec3 color;
out vec4 v_color;
uniform mat4 mvp;
void main(void)
{
gl_Position = mvp * vec4(vertex,1.0);
v_color = vec4(color,1.0);
}
#version 400
in vec4 v_color;
void main(void)
{
gl_FragColor = v_color;
}
glCreateProgram error
'0 726392815808 > i'&(15!:0)
cder : 2 0
A second attempt to run shader DOES produce around 6 error boxes in
sequence, each regarding "error in a_g_initialize" .
These don't produce any terminal output at all. Perhaps the first run
leaves stuff lying around in memory and/or locales.
Removing "version 2.0" in the cc opengl command (as Bill had suggested)
doesn't seem to affect matters.
I get the impression that quickview2 and samegame are now performing
correctly, though I don't know what they are supposed to do!
The version information is:
JVERSION
Engine: j701/2011-01-10/11:25
Library: 8.02.09
Qt IDE: 1.1.2/5.3.0
Platform: Win 64
Installer: J802 install
InstallPath: c:/d/j802
Thanks again

Zdravstvuitye, Bill!
But shader isn't of particular concern for me - I ran it since you
asked, but what I'm still principally interested in is the slow
loading of JQT on my machine.
NB. I haven't snipped the rather long history below this! [I have now
- 3/6/14!]
Thanks again for any help,
Mike

Thanks Mike! I received other report that shader did not work
for win8. For the time being, you may use the ANGLE version of
Qt libraries if you want opengl.
I have no idea why your win8 is so slow other than some
background scan or disk read/write activity. FWIW the total size
of windows 64-bit Qt 5.3 library is about 100MB. There will be a
slim version.
