Some operating systems restrict the length of the command line. You can either:
specify options that extend beyond this limit by including them in a text file
place all of your command-line options in a text file.
To use a text file to specify command-line options:
Create a text file containing the required command-line options. The options must be specified on a single line. For example:
--debug --cpu=ARM926EJ-S
Use the
--viacommand-line option to specify the file location containing the required options. For example:armcc --via myoptions.txt
You can use any filename extension, or no filename extension.
Priority of command-line options when using them in
a text fileThe compiler reads the command-line options from the specified file and combines them with any additional options you have specified on the command-line. The priority given to a command-line option depends on:
the command-line option
the position of the --via option on the command-line.
To see the priority of the options, specify the --show_cmdline option.
For example, if armcc.txt contains the options --debug
--cpu=ARM926EJ-S:
armcc -c --show_cmdline --cpu=ARM7TDMI --via=armcc.txt hello.c [armcc --show_cmdline --debug -c --cpu=ARM926EJ-S hello.c]In this case,
--cpu=ARM7TDMIis not used because--cpu=ARM926EJ-Sis the last instance of--cpuon the command-line.armcc --via=armcc.via -c --show_cmdline --cpu=ARM7TDMI hello.c [armcc --show_cmdline --debug -c hello.c]In this case,
--cpu=ARM926EJ-Sis not used because--cpu=ARM7TDMIis the last instance of--cpuon the command-line. In addition,--cpu=ARM7TDMIis not shown in the output, because this is the default option for--cpu.
