External Builder: Cannot run program "rm": Command line too long #643
Description
Hello, I have a big project which have a lot of files, and I faced a issue during link and clean process, it is caused by windows 32k command line limit, I have searched in website, found the following bugs
- related to long rm command line https://bugs.eclipse.org/bugs/show_bug.cgi?id=505882
- related to long link command line https://bugs.eclipse.org/bugs/show_bug.cgi?id=72965
For the first one, is current embedded cdt also fixed, for our IDE based on embedded cdt, this issue still present, but I can manually change the C/C++ Build -> Tool Chain Editor -> Current builder -> Gnu Make Builder select it and do Apply and close, and then do clean project and build project, and clean project, then you will see the clean target changed.
# orginal target
clean:
-$(RM) $(CCM_DEPS)$(C_UPPER_DEPS)$(SECONDARY_LIST)$(SECONDARY_SIZE)$(CXXM_DEPS)$(C_DEPS)$(CC_DEPS)$(SX_DEPS)$(C++_DEPS)$(OBJS)$(CXX_DEPS)$(SECONDARY_FLASH)$(ASM_DEPS)$(S_UPPER_DEPS)$(C++M_DEPS)$(CPP_DEPS) 2222.elf
-@echo ' '
# new target
clean:
-$(RM) 2222.elf 2222.hex 2222.lst 2222.siz
-@echo ' '
I have create a project to test it, you can check it in ide_better_clean-target.zip, this is a git maintained project, so just check last commit change via git log -1 -p
Regarding the link command line too long issue, we can try with gcc response file like this
We can add new line in elf generation target like this
@echo 'Building target: $@'
# Add after it
@echo 'Generate response file: [email protected]'
$(file >$@.linkargs,$(OBJS) $(USER_OBJS) $(LIBS))
# replace key words
In later lines replace $(OBJS) $(USER_OBJS) $(LIBS) to @$@.linkargsThen it can fix linker command line too long issue, but can this be done directly in embedded cdt?
Thanks
