No rule to make target install But Makefile exists

Question

I am running into issues installing a C   library  The CMake command is successful and generates the Makefile  but it gives a warning   CMake Warning  dev  at CMakeLists txt 27  LINK DIRECTORIES   This command specifies the relative path     usr local lib  as a link directory   Policy CMP0015 is not set  link directories   treats paths relative to the source dir   Run  cmake --help-policy CMP0015  for policy details   Use the cmake policy command to set the policy and suppress this warning  This warning is for project developers   Use -Wno-dev to suppress it    Line 27 in CMakeLists txt is  Boost LIBRARY DIR DEBUG PATH  usr local lib   I don t see why this warning would cause me any issues  But when I run make install  I get an error   make      No rule to make target  install    Stop    Any ideas

I was receiving the same error message  and my issue was that I was not in the correct directory when running the command make install  When I changed to the directory that had my makefile it worked   So possibly you aren t in the right directory

Could you provide a whole makefile  But right now I can tell - you should check that  install  target already exists  So  check Makefile whether it contains a  install   anything there    line  If not  there is no such target and so make has right  Probably you should use just  make  command to compile and then use it as is or install yourself  manually   Install is not any standard of make  it is just a common target  that could exists  but not necessary

I also came across the same error  Here is the fix  If you are using Cmake-GUI   Clean the cache of the loaded libraries in Cmake-GUI File menu  Configure the libraries  Generate the Unix file   If you missed the 3rd step       No rule to make target  install    Stop   error will occur
