Re: RE: [MXE-Octave]Build Failed on CentOS6.6 64bit

[Tatsuro MATSUOKA]

This is a correction.

Mxe-octave will build their own bunutils.
If you finished mxe build, you have dist/octave-4.0.0/bin directory.
$ cd ( path to dist/octave-4.0.0/bin in your mxe directory tree)
$ ./ld -v
You can check bunutils version. (e.g. GNU ld (GNU Binutils) 2.25)
As I wrote

If version of binutils in your mxe tree is 2.25,

modify src/openblas.mk

From
define $(PKG)_BUILD
    $(MAKE) -C '$(1)' -j '$(JOBS)' $($(PKG)_MAKE_OPTS)  
    $(MAKE) -C '$(1)' -j 1 $($(PKG)_MAKE_OPTS) install
endef

to
define $(PKG)_BUILD
    PATH=(path to dist/octave-4.0.0/bin in your mxe directory tree ):$PATH 
$(MAKE) -C '$(1)' -j '$(JOBS)' $($(PKG)_MAKE_OPTS)  
    $(MAKE) -C '$(1)' -j 1 $($(PKG)_MAKE_OPTS) install
endef

and

Try to build openblas again.


Another option is to upgrade your binutils to ver. 2.25 on your system.
http://rpmfind.net/linux/rpm2html/search.php?query=binutils


and back to
> $(PKG)_MAKE_OPTS := PREFIX=$(HOST_PREFIX) DYNAMIC_ARCH=1 NO_LAPACK=1

is also required

Do not forget to backup libopenblas.so, libopenblas.a in your 
dist/octave-4.0.0/lib to somewhere 
before re-build because they are working openblas.
