!MAGMA 1.0
[MAGMA 1.0|http://icl.cs.utk.edu/magma/]をコンパイルして試してみよう...と
したのだけど，一筋縄では上手くいかなかった．
試した環境は，CUDA SDK 3.2と GotoBLAS2 な環境．
 ../lib/libmagma.a(zlatrd.o): In function `magma_zlatrd':
 zlatrd.cpp:(.text+0x3ce): undefined reference to `zdotc'
 zlatrd.cpp:(.text+0xd16): undefined reference to `zdotc'
というエラー．で，検索してみるとフォーラムに↓な書き込みが．

と修正．clatrd.cppでも同様のエラーが発生したので，修正

工作モードからシフトチェンジせねば．
