我编译octave不通过。看了看log,有下面一段话:
***********************************************************
*
* To compile Octave, you will need a recent versions of
* the following software:
*
* GNU Make (a recent version)
*
* g++ (preferably a recent 4.x version, though later
* 3.x versions may also work)
*
* flex (2.5.4 or a more recent version) -- required if
* you need to recreate lex.cc from lex.l
*
* bison (1.31 or a more recent version) -- required if
* you need to recreate parse.cc from parse.y
*
* gperf (3.0.1 or a more recent version) -- required if
* you need to recreate oct-gperf.h from octave.gperf
*
* Now would be a good time to read INSTALL.OCTAVE if
* you have not done so already.
*
***********************************************************
我对了一些,基本都满足,就是flex好像版本不满足:
yjhu@localhost ~ $superuser access is required... adding --pretend to options.
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-devel/flex-2.5.35 USE="nls -static" 1,228 kB
Total: 1 package (1 reinstall), Size of downloads: 1,228 kB
我如何强制安装2.5.4版本的flex呀? |
