I need help. I try to build JRTPLIB 3.1.1 with SRTP 2.1.0 and OpenSSL 1.1.0 but got linker error while try to make JRTPLIB.
Dependencies:
Debian 9 (also tried on Ubuntu 16.04 LTS)
JRTPLIB v.3_1_11(from git+changes)
JTHREAD v.1_3_3 (from git)
LIBSRTP v.2_1_0 (by tag)
LIBSSL v.1_1_0 Stable (by branch)
Source changes:
JRTPLIB v.3_1_11 (from git): changed srtp to srtp2; link to lib source archive: https://drive.google.com/drive/folders/0B_Q0HXvHrCzabVpsSUp0TXNka1U?usp=sharing
Cmake settings (image cmake_JRTPLIB.JPG): https://drive.google.com/drive/folders/0B_Q0HXvHrCzabVpsSUp0TXNka1U?usp=sharing
Build:
1)OpenSSL:
build from source and also tried on a Virtual Machine to install libssl1.1 and libssl-dev by sudo apt-get install libssl1.1 libssl-dev)
2)libSRTP:
$./configure --enable-debug-logging --enable-log-stdout --enable-openssl
3)JTHREAD: build with cmake
4)JRTPLIB: Cmake config - see image cmake_JRTPLIB.JPG
$make

You can see that I've commented out a number of attempts at getting this imported. CMake does not throw any errors. However, if I try building the project, I get:

The library to link with is likely not in the include directory with the header files. It's more likely they're in a lib directory:

Hello and thanks in advance for the help,
I have a linking issue with my cmake that I don't get. I'm trying to include a shared lib(modbuspp) in submodule which require another shared lib(libmodbus) on my computer. It seem simple but during exec linking it give me undefined reference to my computer lib (libmodbus) when I did add the includes. Does anyone has an idea why ? Here is my Cmake:

I've extracted official llvm/clang sources for 3.7 release, did some minor patching (NSGetEnviron()), configured and build for iOS with cmake:
cmake ../llvm_37_ios \

For some reason shared library was created but static was not:

Did i miss something or it's clang configuration bug?
libclang is built as a shared library by default because it simplifies consumption from other languages such as Python using FFI or similar mechanisms.
To build a static library use LIBCLANG_BUILD_STATIC CMake option defined in clang/tools/libclang/CMakeLists.txt:
option(LIBCLANG_BUILD_STATIC
"Build libclang as a static library (in addition to a shared one)" OFF)
You can use it as follows:
cmake -DLIBCLANG_BUILD_STATIC=ON ...
I tried to install mlpack in cygwin and I have already installed armadillo, but I encountered following problems:
After running cmake ../ I run the make command and here is the process:

I don't know how to deal with this problem.
Cygwin's gnulib does not provide execinfo.h, possibly due to compatibility issues with the underlying (Windows) system.
From the gnulib documentation:
This header file is missing on some platforms: Mac OS X 10.3, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin, mingw, MSVC 9, Interix 3.5, BeOS.
You may want to try a WinAPI function like CaptureStackBackTrace instead.

That's probably not your problem, but one idea is to try to install OpenCV 32-bits:
brew install opencv --32-bit
And if that doesn't work:
please report the bug:
https://github.com/mxcl/homebrew/wiki/checklist-before-filing-a-new-issue
You can always download OpenCV source code and compile it yourself. It's what I did on Mac OS X.
