[Bug 1200527] Re: compiler flags order bug

[Dmitrijs Ledkovs]

I believe this is an intentional linker change.
Libraries that provide a symbol, must come after said symbol is used.

Title:
  compiler flags order bug

Status in “gcc-4.6” package in Ubuntu:
  Invalid

Bug description:
  When I compile a open source software
  "2HDMC"(http://2hdmc.hepforge.org/) on my computer,  it occurs
  "SM.cpp:(.text+0x4d8): undefined reference to `gsl_matrix_set'".

  platform: Ubuntu12.04LST

  The compiler:  g++ version 4.6.3)

  flags :   -lgsl -lgslcblas -Llib -l2HDMC

  
  when I use flags:  -Llib -l2HDMC   -lgsl -lgslcblas, it works!

  when I user g++-4.4 , the makefile also works!

  So, it must be wrong on the flag orders of g++-4.6.3
