iar中make和compile 的原意如下
make:Brings the current build configuration up to date by compiling, assembling, and linking only the files that have changed since the last build.
Compiles :Compiles or assembles the currently selected file, files, or group.
One or more files can be selected in the Workspace window—all files in the same project, but not necessarily in the same group. You can also select the editor window containing the file you want to compile. The Compile command is only enabled if every file in the selection is individually suitable for the command. You can also select a group, in which case the command is applied to each file in the group (including inside nested groups) that can be compiled, even if the group contains files that cannot be compiled, such as header files.
