[texhax] pdflatex could not recognize .eps

[Tran Hong Quang]

Hi,

I use package graphicx in order to add .eps file into my latex file. I then
use \includegraphics{my_file.eps}.
Then I run latex, no problem. Since I need .pdf or .ps file, so I use
pdflatex ti compile but I got error.
LaTeX error: Unknown graphics extension.

I then tried dvi2ps: no error, but the document .ps is nearly blank.

Anyone can help me out? Thanks
