build problem

[sagaertj]

Hi Make Error at /home/buildroot12git/output/host/usr/share/cmake-3.1/Modules/ExternalProject.cmake:1584 (message): error: no download info for 'jansson' -- please specify existing/non-empty SOURCE_DIR or one of URL, CVS_REPOSITORY and CVS_MODULE, SVN_REPOSITORY, GIT_REPOSITORY, HG_REPOSITORY or DOWNLOAD_COMMAND

How do i solve this, besides this i want to crosscompile this for embedded usage.

I think you miss command to download jansson dependency: git submodule update --init

It looks like that jannsson is compiled for the host I guess something needs to be changed in the cmake source files.

followup:

After running cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="/home/buildroot12git/output/host/usr/share/buildroot/toolchainfile.cmake" -DCMAKE_INSTALL_PREFIX=//home/buildroot12git/output/staging/usr -DUSE_CCACHE=OFF ../

i modified build/CMakeFiles/apn-pusher.dir/link.txt and build/CMakeFiles/capn.dir/link.txt

have replaced
../src/third_party/jansson/lib/libjansson.a
into -ljansson

then ran make again

So since i already had a cross libjansson on my target system using that one solved the jansson problem. This is just a quick and dirty fix, maybe the cmakefiles need some tweaking . I am always available to test things if you have modified something in the cmake project to resolve this.
