[gentoo-science] Compiling the development version of GNU Octave

[José Romildo Malaquias]

Hello.

I want to try the development version of GNU Octave[1] on my ~amd64
gentoo linux system.

After cloning the repository[2], reading the instructions at [3],
bootstrapping, changing to directory .build and running ./configure, I
am getting the error messages:

[...]
checking for sgemm_ in -lblas... (cached) no
../configure: line 32516: test: =: unary operator expected
../configure: line 34026: test: =: unary operator expected
../configure: line 35581: test: =: unary operator expected
configure: error: BLAS and LAPACK libraries are required


Any clues?

I appears you have to configure octave with the output of pkg-config --libs
{blas/lapack}. Here I have

$ pkg-config --libs blas
-lrefblas

$ pkg-config --libs lapack
-lreflapack -lrefblas

So the following configure works here

../configure --with-blas=refblas --with-lapack=reflapack

Or you may get something like this (all on one line) to work

../configure --with-blas=`pkg-config --libs blas | sed 's:-l::g' | sed
's:[[:space:]].*$::g'` --with-lapack=`pkg-config --libs lapack | sed 's:-l::g'
| sed 's:[[:space:]].*$::g'`

There may be other things that are missing but I'm able to generate the
makefiles with the above.
