Very simple application fails with “multiple target patterns” from Eclipse

Question

Since I\'m more comfortable using Eclipse, I thought I\'d try converting my project from Visual Studio. Yesterday I tried a very simple little test. No matter what I try,

Answer 1

according to other internet sources this is related to a problem that cygwin make has with windows path names, specially the c:. For me it workes fine with setting relative paths instead.

e.g. if you have something like

proj/mymodule/headers/afile.h
proj/mymodule/source/abc/afile.c

just add ../mymodule/headers/ as include path in the project configuration for the compiler this will find the header afile.h and will generate make files with relative path. (compiler command will have the statement -I../mymodule/headers/ )

looks like execution directory is always the project base directory.

Answer 2

Are you working from a Cygwin installation?

I've seen this problem before using Cygwin--basically, make sees the : in the path and thinks it is another target definition, hence the error.

If you are working from a Cygwin installation, you might try replacing the c:/ with /cygdrive/c/. If not, you might try using relative paths or using a network mount and see if that fixes it.

Answer 3

One change that worked for me (I use Cygwin and SSH terminal into an SVN server in parallel) was to delete the .d files. When I called the make -f makefile from Cygwin, it broke something. I usually compile from the Putty terminal, and after deleting the .d files from my project it stopped complaining about the multiple targets.
