[khangprolxag]

i'm using Ubuntu 16.04 ... but when I tried to compile it cause a lot of problems..
undefined reference to sio::client::socket undefined reference tosio::client::connect, ..

please help me, thank you

[emmanuelgeoffray]

Hi @khangprolxag
Are you compiling the example app ?
If not, could you try to compile it first please ?

[khangprolxag]

I've tried to compile it with "make" command and it showed that error . Did i miss somethings? Thanks for reply me! 

[hugohil]

Can you trace the make output back to the error and put it there, please ?

I hope you can fix it..

Hi,

I am having the same issue. Did anybody find a solution for this?
To my novice eyes this looks like the linux64 libraries couldn't be linked properly or the libraries don't contain the implementation declared in the libraries header files.

My setup:
openframeworks 0.9.8
Ubuntu 16.04 LTS

Does anyone know how to fix this?

[neobits]

I'm having the same errors with OF 0.11.0 on a raspberry 4.
But I'm still cannot fix this.

[neobits]

https://forum.openframeworks.cc/t/how-to-link-static-library-in-android-project/16584/2

PROJECT_LDFLAGS= -lsndfile -L$(PROJECT_ROOT)/bin/libs
PROJECT_LDFLAGS= $(PROJECT_ROOT)/bin/libs/libsndfile.a

But this didn't helped.

Kindly from khangprolxag there's a fix on Raspberry Pi (ARM architecture):
