  1. POgcc - How to remove all absolute path from static library output (.a)
    text
    copied!<p>I am using GCC for ARM (<a href="http://www.code-red-tech.com/red-suite-4-nxp.php" rel="nofollow">Red Suite 4 NXP</a>). I am compiling static library files (.a) that are used for a final application. I need to configure the project so any developer can produce the exact same static library output. (This is mainly so a new developer can verify they have their setup correct.) I have two copies of my project (two checkouts from SVN). When I build with each, I notice some absolute path information in the static library .a output files. This means that SVN detects as a change. I'm using the ar -D (deterministic) option already. Are there any other options to remove path information? I tried gcc -s but this didn't work (it appears this is only for final executable, not libraries)</p> <p>I don't know where/why the absolute paths are in the .a, but I can provide more information if someone can point me in the right direction. </p> <p>I've looked at the strip utility man pages (haven't tried it yet), would this remove this path information?</p> <p>Also, I am using Red Suite to manage the project, so I'm trying to do things the Red Suite way (and to let it do its thing). However, if there is a gcc or ar option I need to adjust, I do know how to do that. I just don't know what option to change.</p> <p>Here is the build console output. This causes the absolute path of my project to be included into the resulting .a. That is what I am trying to fix.</p> <pre><code>**** Build of configuration Release for project lib_touch **** make -j all Building file: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/Touch.c Building file: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchCalibration.c Building file: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchPoint.c Building file: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchEventQueue.c Invoking: MCU C Compiler Invoking: MCU C Compiler arm-none-eabi-gcc -D__REDLIB__ -DNDEBUG -D__CODE_RED -D__USE_CMSIS=CMSISv2p00_LPC177x_8x -I"C:\Users\my_user_name\Documents\My Project Verification build\src\build\RedSuite4NXP\CMSISv2p00_LPC177x_8x\inc" -I../../../../board -I../../../../board/lpc1788 -I../../../../communication -I../../../../events -I../../../../geometry -I../../../../graphics -I../../../../hmilogic/include -I../../../../sound -I../../../../util -O3 -Wall -Werror -c -fmessage-length=0 -fno-builtin -ffunction-sections -fdata-sections -std=gnu99 -mcpu=cortex-m3 -mthumb -MMD -MP -MF"touch/Touch.d" -MT"touch/Touch.d" -o"touch/Touch.o" "C:/Users/my_user_name/Documents/My Project Verification build/src/touch/Touch.c" arm-none-eabi-gcc -D__REDLIB__ -DNDEBUG -D__CODE_RED -D__USE_CMSIS=CMSISv2p00_LPC177x_8x -I"C:\Users\my_user_name\Documents\My Project Verification build\src\build\RedSuite4NXP\CMSISv2p00_LPC177x_8x\inc" -I../../../../board -I../../../../board/lpc1788 -I../../../../communication -I../../../../events -I../../../../geometry -I../../../../graphics -I../../../../hmilogic/include -I../../../../sound -I../../../../util -O3 -Wall -Werror -c -fmessage-length=0 -fno-builtin -ffunction-sections -fdata-sections -std=gnu99 -mcpu=cortex-m3 -mthumb -MMD -MP -MF"touch/TouchCalibration.d" -MT"touch/TouchCalibration.d" -o"touch/TouchCalibration.o" "C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchCalibration.c" Invoking: MCU C Compiler Invoking: MCU C Compiler arm-none-eabi-gcc -D__REDLIB__ -DNDEBUG -D__CODE_RED -D__USE_CMSIS=CMSISv2p00_LPC177x_8x -I"C:\Users\my_user_name\Documents\My Project Verification build\src\build\RedSuite4NXP\CMSISv2p00_LPC177x_8x\inc" -I../../../../board -I../../../../board/lpc1788 -I../../../../communication -I../../../../events -I../../../../geometry -I../../../../graphics -I../../../../hmilogic/include -I../../../../sound -I../../../../util -O3 -Wall -Werror -c -fmessage-length=0 -fno-builtin -ffunction-sections -fdata-sections -std=gnu99 -mcpu=cortex-m3 -mthumb -MMD -MP -MF"touch/TouchEventQueue.d" -MT"touch/TouchEventQueue.d" -o"touch/TouchEventQueue.o" "C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchEventQueue.c" Finished building: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/Touch.c arm-none-eabi-gcc -D__REDLIB__ -DNDEBUG -D__CODE_RED -D__USE_CMSIS=CMSISv2p00_LPC177x_8x -I"C:\Users\my_user_name\Documents\My Project Verification build\src\build\RedSuite4NXP\CMSISv2p00_LPC177x_8x\inc" -I../../../../board -I../../../../board/lpc1788 -I../../../../communication -I../../../../events -I../../../../geometry -I../../../../graphics -I../../../../hmilogic/include -I../../../../sound -I../../../../util -O3 -Wall -Werror -c -fmessage-length=0 -fno-builtin -ffunction-sections -fdata-sections -std=gnu99 -mcpu=cortex-m3 -mthumb -MMD -MP -MF"touch/TouchPoint.d" -MT"touch/TouchPoint.d" -o"touch/TouchPoint.o" "C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchPoint.c" Finished building: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchEventQueue.c Finished building: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchCalibration.c Finished building: C:/Users/my_user_name/Documents/My Project Verification build/src/touch/TouchPoint.c Building target: lib_touch.a Invoking: MCU Archiver arm-none-eabi-ar -rD "lib_touch.a" ./touch/Touch.o ./touch/TouchCalibration.o ./touch/TouchEventQueue.o ./touch/TouchPoint.o c:\code_red\RedSuiteNXP_4.3.0_1033\redsuite\tools\bin\arm-none-eabi-ar.exe: creating lib_touch.a Finished building target: lib_touch.a make --no-print-directory post-build Performing post-build steps arm-none-eabi-size "lib_touch.a" ; cp "lib_touch.a" "../../../../lib/lib_touch.a"; # arm-none-eabi-objdump -h -S "lib_touch.a" &gt;"lib_touch.lss" text data bss dec hex filename 1864 0 156 2020 7e4 Touch.o (ex lib_touch.a) 576 0 0 576 240 TouchCalibration.o (ex lib_touch.a) 320 0 0 320 140 TouchEventQueue.o (ex lib_touch.a) 96 0 0 96 60 TouchPoint.o (ex lib_touch.a) </code></pre> <p>UPDATE: MORE INFORMATION</p> <p>I have done some more digging, and it appears the full file path is in front of a string constant.
