Eclipse's C/C++ Development Tooling (CDT) uses GNU makefiles to manage dependencies. The differences between supported shell characters on Windows and Linux systems results in a number of file and path limitations in Eclipse projects. Command-lines containing a character that is not supported on the host Windows or Linux system result in command-line parsing errors that cause projects to fail to build. ARM recommends that you:

• On Windows: do not place a backslash at the end of include paths. 
  For example, always use H: rather than H:\

• On all platforms: do not use spaces in file names.
  C:\Work is a good choice of Eclipse workspace on Windows

• On Linux or in UNIX-style shells on Windows: use quotes around command-line options such as 
  --first and --keep that contain parentheses:
  
  armlink "--first=init.o(init)" "--keep init.o(reset)" main.o -o main.axf

• On Windows: do not use the MSYS shell. Command-line options such as --apcs that start with forward slashes will cause builds to fail on Windows under the MSYS shell.
