Hi all,<br>
<br>
Looks like I am following the long line of people failing to build numpy<br>
:). I must admit I am clueless with building problems.<br>
<br>
Numpy builds alright, but I get:<br>
<br>
ImportError: /usr/lib/sse2/atlas/libblas.so.3gf: undefined symbol:<br>
_gfortran_st_write_done<br>
<br>
On import.<br>
<br>
This used to work a while ago. I am not sure what I changed, but it sure<br>
does fail. I really don&#39;t understand where the gfortran comes in. I tried<br>
building numpy with or without gfortran. From what I gather it is the<br>
numpy is being built by a different compiler than the atlas libraries<br>
(hurray for ABI compatibility), but I don&#39;t really understand how this is<br>
possible.<br>
<br>
How can I debug this?<br>
<br>
Cheers,<br>
<br>
Gaël<br>
