Re: [Bino-list] configure failure of bino package

[Krishna Kishore]

Hi Martin,

  Yes. I set it correctly. 

        $ export CXXFLAGS="-march=i686"
        $ export CFLAGS="-march=i686"
        $ ./configure

   Also,
      $ ./configure CFLAGS="-march=i686" CXXFLAGS="-march=i686"

Regards,
Kishore.

Hi, 

did you set it in the correct way, i.e.

$ ./configure CFLAGS="-march=i686" CXXFLAGS="-march=i686"
