how to speed up the compiling?

Are you able to isolate it to a particular file/set of files that take longer to build than others? Is most of the time spent in the compilation (optimizer) stage or in the linker stage? How many files are in your project?

Does it build faster if optimization is disabled? What is the version of code generation tools being used - you can check this by going into Help->Component Manager and expanding Build Tools and checking the version of the C6000 code generation tools.

Yes,the opt6x.exe costs most of the time.

Yes,if no optimization ,such as -o2 ro -o3, is chosen. The compiler will success very quikly.But if without choosing optimization level,it will reduce the preformance of my project.

The version of cg6x.exe is v6.0.27.

Thank you very much for your help.what can I do? do I need to change the version of my cg6x.exe?

My project is large.There are aboot 15 files.

Do you mean I should try to compile one file seperately?

Thank you  for your help .

I have try like you said.Yes, it can speed up.But I find it seems to get a .out file without optimization.is it right?

I use the code generation tools is v6.0.27.Can it choose the -oi100 ? Or only version 6.1.* or later can use -oi100 optimization levle ?

v6.0.x codegen tools do support the -oi[size] option, so you can specify a threshold for automatic inlining.

Thank you very much!

If -oi[size] is chosen,  Is the project optimized (like -o2 or -o3)?

-oi is useless without -o.  -oi will not turn on optimization, you must still use -o2 or -o3.  For instance:

cl6x -o2 -oi0 file.c

Thank you very much!!

Wish you happy every day!
