I tried to install Bison according to the instructions. When I configure the source code with
./configure in my directory
the error message below appears:
checking for GNU M4 that supports accurate traces... configure: error: no acceptable m4 could be found in $PATH. GNU M4 1.4.6 or later is required; 1.4.16 or newer is recommended. GNU M4 1.4.15 uses a buggy replacement strstr on some systems. Glibc 2.9 - 2.12 and GNU M4 1.4.11 - 1.4.15 have another strstr bug.
Though I have already included M4 in my PATH variable with
PATH=$PATH:/home/LCU1/m4-1.4.17/bin. However, I cannot find a folder named
/m4-1.4.17 in the file manager.
