[Users] questions about compilation

[Roland Haas]

Hello Chia Hui Lin,

hmm. I am not sure about the -ljpeg since ExternalLibraries/libjpeg
should provide this. 

You are also receiving a link time warning about using dlopen in a
statically linked application. While not directly related to the jpeg
library issue a possible workaround is force dynamic linking (not the
default one edison) by setting:

export CRAYPE_LINK_TYPE=dynamic
export CRAY_ADD_RPATH=yes

either as part of the envsetup lines in the file
simfactory/mdb/machine/edison.ini or on your command line (if eg not
using simfactory).

Yours,
Roland
