error: request for member ‘draw’ in ‘ofEvents’, which is of non-class type ‘ofCoreEvents&()

[benbridts]

I'm trying to compile lpmt on a Raspberry Pi with Arch ARM.

This it what I've done. Can you tell me If i've forgotten something or done something wrong?

EDIT: I always got the master branch from each project

• Got openFrameworks from https://github.com/openframeworks/openFrameworks and extracted it to ./OF
• ran install_codeblocks.sh, install_codecs.sh and install_dependencies.sh form OF/scripts/linux/archlinux
• pacman -S base-devel glew gstreamer0.10-base just to be sure
• downloaded addons to OF/addons:
  • ofxMostPixelsEver from https://github.com/Flightphase/Most-Pixels-Ever
  • ofxMSAInteractiveObject and ofxSimpleGuiToo from https://github.com/memo/msalibs
• Downloaded and unzipped lpmt to OF/apps/extra/lpmt
• cd OF/apps/extra/lpmt

But when I run make I get these errors (output from stderr)

the error in mostPixelsEver addon is due to a change introduced in OF 071, you must change any occurrence of 'ofEvents' to 'ofEvents()'. I suggest you to get ofxSimpleGuiToo from my branch as well, as it is tailored for LPMT. Actually you should probably expect more troubles in compiling lpmt on rasperry pi, I'm not sure OF has been tested on the pi yet, and porting things to it seems quite a hard job. I'm very curious about it, as I just got a rasperry pi myself. please, keep me informed about your effort.

Update:

• I replaced ofEvents in both MostPixelsEver and MSAInteractiveObject (source can be found on my github page)
• I got your branch of SimpleGuiToo and ofxTextInputField from https://github.com/Flightphase/ofxTextInputField
• I added ofxTextInputField to addons.make

Compiling seems to work now, but the linker fails on some missing static libs. So then I did (not ideal, but good enough when trying to get things working)

• edited the make file to use LIBSPATH=android/armeabi (these should be the same libs)
• copied OF/libs/openFrameworksCompiled/lib/linux (compiled when installen OF) to OF/libs/openFrameworksCompiled/lib/android/armeabi
• ran make again

Now i get make: *** No rule to make target../../../libs/poco/lib/android/armeabi/libPocoUtil.a', needed by bin/lpmt'. Stop. There is a libPocoUtil.a for linux(i386) but not for arm, so I'm now going to try to compile libPoco on the RPI

I'm afraid porting OF on raspi needs to find a solution to the problem of Glut not being usable with OpenGL ES.
