Hi Team, Can someone list all the steps to compile the code after cloning the repository from [GitHub - openziti/ziti-tunnel-sdk-c](https://github.com/openziti/ziti-tunnel-sdk-c.git) Thanks. Shiv ---

Hi Shiv - you’re just trying to build? Are you familiar with cmake? ---

I have used it but not too familiar with setting it up. ---

Assuming you’re not cross-compiling, give this a try after the clone: ```auto $ mkdir ziti-tunnel-sdk-c/build $ cd ziti-tunnel-sdk-c/build $ cmake .. && make ``` ---

Hi Dave, I have been trying to cross compile Ziti -tunnel-sdk-c for windows using Ubuntu and the following command: cmake -DCMAKE\_SYSTEM\_NAME=Windows -DCMAKE\_C\_COMPILER=i686-w64-mingw32-gcc -DCMAKE\_CXX\_COMPILER=i686-w64-mingw32-g++ WIN32 … && make but have got stuck and not sure what I need to do toresolve this.

I tried using the toolchains file and get a slightly different error ```bash # install mingw-w64: sudo apt install mingw-w64 # make/cd the build folder mkdir build cd build # gen the project using cmake and the toolchain file cmake .. -DCMAKE_TOOLCHAIN_FILE=../toolchains/Windows-x86.cmake # cmake build cmake --build . ``` Error I see is at ```auto [69%] Generating zlib1rc.obj /bin/sh: 1: windres: not found make[2]: *** [_deps/zlib-build/CMakeFiles/zlib.dir/build.make:62: _deps/zlib-build/zlib1rc.obj] Error 127 make[1]: *** [CMakeFiles/Makefile2:1571: _deps/zlib-build/CMakeFiles/zlib.dir/all] Error 2 make: *** [Makefile:163: all] Error 2 ``` @ekoby - can you take a look? ---

Oh and I just noticed I was building the sdk-c not the tunneler-sdk-c - my bad. ---

Thanks Clint, as a side note I have also had to fix following in order to be able to compile, not sure if it is something that needs to get fixed from your side or not: In file included from /home/daniel/ZITI/ziti-tunnel-sdk-c/build/\_deps/ziti-sdk-c-src/library/ziti-socket.c:33: /home/daniel/ZITI/ziti-tunnel-sdk-c/build/\_deps/ziti-sdk-c-src/library/…/includes/ziti/socket.h:31:10: fatal error: WinSock2.h: No such file or directory 31 | #include \ | ^ ~~~~~~~~~~~ Edited: vi /home/daniel/ZITI/ziti-tunnel-sdk-c/build/\_deps/ziti-sdk-c-src/library/…/includes/ziti/socket.h Changed: #include \ to read #include \ also have had to copy cp \_deps/wintun-src/bin/x86/wintun.dll \_deps/wintun-src/bin/ as wintun was missing ---

I can’t replicate the issue you’re seeing @Danieleb . On my Ubuntu 20 install with cmake 3.16.3 i can generate the project fine with: ```auto cmake -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_C_COMPILER=i686-w64-mingw32-gcc -DCMAKE_CXX_COMPILER=i686-w64-mingw32-g++ WIN32 .. ``` However running just `make` or `cmake --build .` both produce the same error for me: ```auto ziti-tunneler-sdk-c/build$ make make: *** No targets specified and no makefile found. Stop. ziti-tunneler-sdk-c/build$ cmake --build . make: *** No targets specified and no makefile found. Stop. ``` I ended up being able to build using: ```auto cmake -DCMAKE_SYSTEM_NAME=Windows --build . ``` I was going to ask you the wintun dll question too 🙂 We only build using a windows build machine in GitHub actions. I don’t know if anyone has tried crosscompiling from Ubuntu for windows yet. I’ll do what you have tried as well and see if i can get to the same place you’re at ---
