[parsec-users] xext lib error when building PARSEC

Hi Ke,


I don't know the library or what this error means. Here is what you can do:


1.       Try to build the mesa library without the PARSEC framework. Mesa is
an open-source implementation of the OpenGL specification. You can also go
to their mailing lists to get help for that, they will probably be able to
help you more.

2.       You might already have an OpenGL implementation on your system, or
you should be able to get one easily. You can link to that with raytrace.
The only thing to look out for is to make sure that your OpenGL
implementation does the rendering in software - your simulator probably does
not support a GPU.

Subject: [parsec-users] xext lib error when building PARSEC


Hi All,

I had trouble building PARSEC on Ubuntu 10.04 when building package
raytrace.  The log displayed in the shell is listed below with the error
message highlighted.  

I have already installed the xext lib, by installing x11proto-xext-dev
package in the Synaptic Package Manager.  And I also tried to modify the
PKG_CONFIG_PATH to /usr/lib where the xext lib is supposed to be installed.
But there is still the same error. 

If you have the same problem before, please give me a hand to solve it.
Thank you for helping.

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XLIBGL_CFLAGS
and XLIBGL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
