make has a very stupid relationship with tabs   All actions of every rule are identified by tabs  And  no  four spaces don t make a tab   Only a tab makes a tab  To check  I use the command cat -e -t -v makefile name  It shows the presence of tabs with  I and line endings with     Both are vital to ensure that dependencies end properly and tabs mark the action for the rules so that they are easily identifiable to the make utility  Example  Kaizen   so test   cat -e -t -v  mk t all ll          here the   is end of line                          ll ll c      Igcc  -c  -Wall -Werror -02 c c ll c  -o  ll        lt       the  I above means a tab was there before the action part  so this line is ok      clean        rm -fr ll     see here there is no  I which means   tab is not present          in this case you need to open the file again and edit ensure a tab     starts the action part

Its pretty old question but still I would like say about one more option using vi vim editor to visualize the tabs  If you have vi vim installed then open a Makefile  e g  vim Makefile  and enter  set list  This will show number of tabs inserted as below     -linux  force   I if      GCC VERSION      2 96      then     I Iecho       Generating build tree for legacy    architecture            I I  CONFIGURE    CWD     legacy      Ielse     I Iecho       Generating build tree for    architecture            I I  CONFIGURE    CWD          Ifi   Icd build-   make
