errors in "make" about online-multiclass-lpboost HOT 8 OPEN

I believe you need to look for getpid in your platform and check which header has it. This is unrelated to eigen and libconfig.

Alternatively, remove the getpid() from that line.

Thank you for your reply. I have added

#include <unistd.h>

to utilities.h. But ,there are more problems in here :

what's wrong? thanks for you time

from online-multiclass-lpboost.

I think the linker is not able to find libconfig. Make sure that you install the correct version of the libconfig .

from online-multiclass-lpboost.

So, where should I install the libconfig to a correct linker? Thank you.

Hi @amirsaffari I met the same libconfig++ linking errors. Specifying the path (/usr/lib/x86_64-linux-gnu) of libconfig++.so in Makefile does not help. I am using Ubuntu 16.04.4, G++ 5.4.0, libconfig++ 9.2.0

from online-multiclass-lpboost.

Move the reference to the library to the end of the line in the make file e.g move -libconf++ to the end of the line it is in

from online-multiclass-lpboost.

I also suffer from the same problem, it is as follow:
Makefile:28: recipe for target 'OMCBoost' failed
make: *** [OMCBoost] Error 1
The version of Libconfig is 1.4.4, it is consistent with the recommended version, can you give me a solution to this problem? Thanks!

Thank you, @admfisher14 ! Worked!!
