: I am having trouble drawing images, using GrDrawImageBits(),
: GrDrawImageFromFile() and GrDrawImageToFit().
: I just followed the examples in 'install.txt'. The examples run fine
: on
: my x86 PC; however, they only run 'partially' on our ARM platform.
: The underlying operating system is uClinux for ARM.
A couple of ideas: make sure that the MAXREQUESTSZ
macro in nanox/nxproto.h is larger than the image
size you're using. Also, you might try using
the LINK_APP_INTO_SERVER=Y config option so that
you eliminate any client/server issues. Finally,
there may be some alignment problems in the
image conversion routines - try a few different
types of image files.

Greg
:
: For GrDrawImageBits(), it causes the error:
: # nano-X: GsError (GrDrawImageBits) Bad graphics context: 1000
:
: For both GrDrawImageFromFile() and GrDrawImageToFit(), it endlessly
: prints out:
: # nano-X: Error accept failed (88)
: where errno of 88 corresponds to:
: #define ENOTSOCK 88 /* Socket operation on non-socket */
: It actually finishes drawing the image and then prints out the error
: message...
: Adding some debug printf's would not reproduce the problem but causes
: nano-X
: server to stop responding even though the other parts of the system
: remain alive.
:
: I tried both 0.89pre8 and 0.89pre7 and the results were similar.
:
: The 'landmine' game and a simple 'hello world' program run fine on our
: system;
: therefore, I think the nano-X server is ok.
:
: Has anyone experienced the same problems?
: Our system is very slow. Does clock speed have anything to do with
: it? (I personally
: do not think so...)
:
: I have trouble sorting out the source of the problems. Could anyone
: give me a hint here?
:
: Thanks. : )
