Question: Getting the error message " Command Line Too Long " from a TI compiler/assembler/linker.

Answer: DOS restricts the length of the command line to a total of 128 characters. The 128 character restriction also exists for the command lines that the compiler shell invokes for calling the other tools (optimizer, code generator...). When these command lines are generated, the entire path is included for the executable

Solution:

• More options can be included if you run the tools from the directory where they exist or if you try to minimize the length of the path to the executable files.
• Use the C_OPTIONS environment variable. However this might not solve the problem in the case of a very long command line. Example (C_OPTIONS solution) below...
• If it's the linker that is sending the error messages, move options to the linker command file.
