expected unqualified-id before 'long'

[jefferai]

I'm trying to use this library and hitting a problem. Below is the (verbose) output. I did notice that the StandardCplusplus.h include does an #undef abs, which I'm assuming is related to this, but including that file or not made no difference in my project. Any ideas?...thanks in advance.

Oh, I'm using Atmel's official toolchain: gcc version 4.6.2 (AVR_8_bit_GNU_Toolchain_3.4.0_663)

I had this issue when I only had:

include StandardCplusplus.h

include vector

I then added the rest of the header files listed in the string-vector example and no longer saw this error message.

Hi! I have the exact same error message and ryantucks tip didn't work. I have all includes of the string-vector example in my test program :-/

[widarr]

I have tried again and I can't even get the example to work the ŕesult is always:

/home/vidar/sketchbook/libraries/StandardCplusplus/cstdlib:60: error: expected unqualified-id before ‘long’ /home/vidar/sketchbook/libraries/StandardCplusplus/cstdlib:60: error: expected )' before ‘long’ /home/vidar/sketchbook/libraries/StandardCplusplus/cstdlib:60: error: expected)' before ‘long’

I would really like to use this lib though :-/

[eric-wieser]

This is because the builtin Arduino.h contains the line #define abs ..., which then ruins the function definition.

This is fixed with #include "StandardCplusplus.h" at the top of all your files, although arguably #undef abs should appear within cstdlib.

[0x0c]

I include Arduino.h after including another C++ library like std::vector and this issue is fixed.

Hi there,

GH-34 has a fix for this, as suggested by @eric-wieser -- thanks! We are hosting a working version at ^1 on behalf of the next branch. Pulling in the StandardCplusplus library by using a PlatformIO configuration like outlined below works for us.

With kind regards, Andreas.

[platformio]
src_dir = .

[env:atmega328p]
platform = atmelavr@^2
board = uno
framework = arduino

[maniacbug]

Merged #34 which fixes this. Thanks!

Wow. Fun to see my bug from 11 years ago get closed! Just a lovely unexpected GitHub notification.
