I'm using Ubuntu Erlang/OTP 19 [erts-8.1] Elixir (1.3.3) in a phoenix application.

However, I'm able to run it without any problems on OSX Erlang/OTP 19 [erts-8.0.2] Elixir (1.3.2).
ejabberd 16.06 is not compliant with Erlang OTP R19. You should use ejabberd 16.09.

Im trying to compile this file ecc-sign.c authored by you.
/home/user/Desktop/contiki-2.7/examples/cc2538-common/pka/ecc-sign.c
but what im getting is the errors below,
LD ecc-sign.z1
ecc-sign.co: In function `process_thread_ecdsa_sign_test':

ecc-sign.c:(.text+0x122): undefined reference to `ecc_compare'
ecc-sign.c:(.text+0x148): undefined reference to `pka_disable'
here is the make file in folder /home/user/Desktop/contiki-2.7/examples/cc2538-common/pka/
CONTIKI_PROJECT = ecc-ecdh ecc-sign ecc-verify
all: $(CONTIKI_PROJECT)
CONTIKI = ../../..
include $(CONTIKI)/Makefile.include
What is the hardware platform you are using?
LD ecc-sign.z1
If it's the Z1, the compilation fails, because this is example is based on the CC2538 chip, which supports hardware acceleration for ECDSA.
The Z1's MSP430 however doesn't and that's why it fails.
I am going to build my Open CV project(C++) in Eclipse, but it gives an error in makefile, the error is
recipe for target `Open_CV.exe' failed
i have also included the lib and opencv in project successfuly, but i don't know why i am getting this error, sometimes i am also getting an error in its subdir file
and Error log is :

I think you missed to link the libcxcore "-lcxcore" (or maybe "-lcvaux").
I'm running OpenCV 2.3.1 on Ubuntu 11.10. I can compile various program I've written myself wih no issue.
Now, however, I have a half-done Haar cascade, that I need to assemble into the xml-cascade file. For this purpose I need to use the included sample program convert_cascade.c. It is not compiled by default, so I need to do that.
Running gcc like this fails:
gcc -lopencv_core -lopencv_highgui -lopencv_objdetect -I/usr/local/include/opencv/ -L/usr/local/lib/ convert_cascade.c -o convert_cascade
It gives me the following errors:

It seems that all the missing functions areare old C-style OpenCV functions prototyped in core_c.h. But including that ( #include <opencv2/core/core_c.h> ) makes no difference. I also tried compiling with the -lopencv_legacy flag (basically just a guess that it might have something to do with older functions), to no avail.
What should I do in order to compile it?
There should be a build_all.sh script in the /samples/c/ directory that will build all the examples for you; no CMAKE tweaks required.
Nevermind. It turned out I had to recompile OpenCV anyway in order to enable TBB, so I simply gave CMAKE the BUILD_EXAMPLES=ON command, and now I have it in a compiled version. I'm pretty sure that is not the proper solution though ;-)
