  4. # Normally configure builds both a static and a shared library.
    5. 

  5. # If you want to build just a static library, use: ./configure --static
    6. 

  6. #
    7. 

  7. # To impose specific compiler or flags or install directory, use for example:
    8. 

  8. #    prefix=$HOME CC=cc CFLAGS="-O4" ./configure
    9. 

  9. # or for csh/tcsh users:
    10. 

  10. #    (setenv prefix $HOME; setenv CC cc; setenv CFLAGS "-O4"; ./configure)
    11. 

  11. 

  12. # Incorrect settings of CC or CFLAGS may prevent creating a shared library.
    13. 

  13. # If you have problems, try without defining CC and CFLAGS before reporting
    14. 

  14. # an error.
