Compile error on weird circumstances

[NicoHood]

Originally I had a huge sketch which failed to compile. The issue could be solved by removing a warning (removed a typedef before an enum). This was weird enough.

I simplified my example and the original "workaround" with the enum was no required anymore. Now including another library caused the error. In the original sketch even more libraries were included, so I guess its a library detection problem.

The sketch:

#include "HID-Project.h"

#include "PinChangeInterrupt.h"

void setup() {
  Keyboard.begin();
}

void loop() {}

Error compiling.

Now I tried to fix this (original sketch) by removing the enum typedef but ran into the next error on adding an if statement. This needs to be fixed.

I also want to note that compiling takes a long time.

I cannot go back in time and use an old arduino builder, since I need the PUSB changes to test this bug. Otherwise my libraries wont compile.

BTW:
PinChangeInterrupt and HID-Project both use .a linkage!

It looks to me that in the last line the 2nd .a file (from HID-Project) is just not included:
"/Arduino/build/linux/work/hardware/tools/avr/bin/avr-gcc" -Wall -Wextra -Os -Wl,--gc-sections -mmcu=atmega32u4 -o "/tmp/builda905e339abe3b59fd5c5e8847955095e.tmp/Remote_USB_MCU_2_test.ino.elf" "/tmp/builda905e339abe3b59fd5c5e8847955095e.tmp/sketch/Remote_USB_MCU_2_test.ino.cpp.o" "/tmp/builda905e339abe3b59fd5c5e8847955095e.tmp/libraries/PinChangeInterrupt/PinChangeInterrupt.a" "/tmp/builda905e339abe3b59fd5c5e8847955095e.tmp/libraries/HID/HID.cpp.o" "/tmp/builda905e339abe3b59fd5c5e8847955095e.tmp/core/core.a" "-L/tmp/builda905e339abe3b59fd5c5e8847955095e.tmp" -lm

Normally it looks like this (other sketch, consumer example):
build/linux/work/hardware/tools/avr/bin/avr-gcc" -Wall -Wextra -Os -Wl,--gc-sections -mmcu=atmega32u4 -o "/tmp/build73dc87b9e01b4b500f5d5759e779d20c.tmp/Consumer.ino.elf" "/tmp/build73dc87b9e01b4b500f5d5759e779d20c.tmp/sketch/Consumer.ino.cpp.o" "/tmp/build73dc87b9e01b4b500f5d5759e779d20c.tmp/libraries/HID-Project/HID-Project.a" "/tmp/build73dc87b9e01b4b500f5d5759e779d20c.tmp/libraries/HID/HID.cpp.o" "/tmp/build73dc87b9e01b4b500f5d5759e779d20c.tmp/core/core.a" "-L/tmp/build73dc87b9e01b4b500f5d5759e779d20c.tmp" -lm

The full sketch (which I was originally testing) then also missed all other libraries that were included and gives a huge error message.

The problem is here: https://github.com/arduino/arduino-builder/blob/master/src/arduino.cc/builder/phases/libraries_builder.go#L101

compileLibrary() gets passed a slice of object files and should add new object files to it, but when DotALinkage is set, it instead takes all the previously compiled object files (including any from other libraries), puts them all into a .a file and then replaces the entire list of object files with a new slice containing just the single .a file.

The correct fix here would be to, if DotALinkage is set, call builder_utils.CompileFilesRecursive() with an empty slice as the first argument and store the result in a new variable (not the existing objectFiles parameter). Then pass that new variable to builder_utils.ArchiveCompiledFiles() and add the resulting .a file to the objectFiles slice.

@ffissore, I presume you will take care of this one?

[NicoHood]

Wow. I am really impressed. :O

Will this code ever get any comments or is it intended to stay like that?

[ffissore]

Comments are scent for smelling code. Plus, they are not executed, hence they can lie (and they usually do)
@matthijskooijman thanks, I'll look into it

[ffissore]

@NicoHood I can't include your code in the test suite as it relies on an unreleased version of the avr core. So I blindly fixed this. Find it in next Arduino IDE hourly build http://www.arduino.cc/en/Main/Software#hourly

[matthijskooijman]

Fix looks good to me (slightly different from what I had in mind, but it should work).

[NicoHood]

Seems to work now.
