Hi 4Diac Team,

i have a questions about the buildsize from forte as posix.
The size of my build is 10MB now,
i have removed the "-g" entries on C_FLAGS_DEBUG, and add "-O3" on C-FLAGS

My forte buildsize from 9M1 is 1,6MB but with the same CMAKE Values have my 9M2 more then 10MB.

Maybe who has a tip for me what i´m doing wrong.

Hi,

this is quite strange. What does the size command (in your case arm-linux-gnueabihif-size) gives you as output. What you you use the arm-linux-gnueabihif-strip command to remove the debug symbols (i.e., arm-linux-gnueabihif-strip -S forte)?

I spent some more thinking on the problem. I noticed that there is a hardecoded -ggdb in line 35 of /src/arch/posix/CMakeList.txt. I think this could cause your issue.

Hello Mr. Zoitl,

thanks for this info!
I have adjusted the entry and now the build have a size from ~1,3MB

in line 35 of /src/arch/posix/CMakeList.txt
--- forte_add_definition("-W -Wall -Wextra -Woverloaded-virtual -Wconversion -DFORTE_LITTLE_ENDIAN -ggdb")
+++ forte_add_definition("-W -Wall -Wextra -Woverloaded-virtual -Wconversion -DFORTE_LITTLE_ENDIAN")

This make my tests easier, the builds are faster and the -tftp upload to my TestPLC runs faster... but i have less time for coffee ;)

Thank you very much!
best regards
Michael

Hi,

thanks for pointing this out. I know we added this a convenience for testing and debugging Forte but it should not be forced on everybody. A better practice is to add this flag in the specific cmake configuration or even better via specific cmake build types (e.g., release, debug). I created an issue in bugzilla [1] based on this discussion.

Yes I'm sorry but I forgot to fix it for RC1. But it will be in RC2.
