Hello

<div>Lately I have been using:</div>

<div>This is an alternative search algorithm code that I find easier to use (Thanks again Martin!). You may want to give it a try</div>

Are these run as part of the daily builds? I can't get it to build.<br>
<br>
Following part 3.18.4.2 of the .pdf manual (I don't think this section has been ported online yet)...<br>
<br>
</div>
In lsopt/, the supplied blas libraries are 10+ years old and my compiler says the Pentium 4 blas1 library is incompatible.<br>
<br>
</div>
<div>In optim/, "make depend" doesn't work (makedepend undefined).<br>
<br>
"make" obviously causes the compiler to complain about -lblas1 not existing.<br>
<br>
After changing the makefile to use -lblas instead of -lblas1, "make" gives the output<br>
<br>
f77 -o optim.x optim_main.o optim_sub.o optim_numbmod.o optim_initmod.o optim_readdata.o optim_writedata.o optim_write_control.o xerbla.o simul.o -L. -L../lsopt/ -llsopt_ecco -lblas<br>
/usr/lib/gcc/x86_64-linux-gnu/<wbr>4.9/../../../x86_64-linux-gnu/<wbr>crt1.o: In function `_start':<br>
(.text+0x20): undefined reference to `main'<br>
optim_numbmod.o: In function `optim_numbmod_':<br>
optim_numbmod.f:(.text+0x1ff1)<wbr>: undefined reference to `ilnblnk_'<br>
optim_numbmod.f:(.text+0x2478)<wbr>: undefined reference to `ilnblnk_'<br>
collect2: error: ld returned 1 exit status<br>
Makefile:78: recipe for target 'optim.x' failed<br>
make: *** [optim.x] Error 1<br>
<br>
</div>
<div>And this just looks like broken code rather than anything BLAS-related. An undefined reference to main, and two undefined references to ilnblnk.<br>
</div>
<br>
ilnblnk is defined with<br>
c == external ==<br>
integer ilnblnk<br>
<br>
</div>
Then used twice as<br>
il = max(ilnblnk(record),1)<br>
<br>
</div>
Any ideas?<br>
</div>
</div></div></div>
