H2o: Not possible to create shared libs

Created on 29 Aug 2016 · 5Comments · Source: h2o/h2o

I am using the following cmake line
cmake -DWITH_BUNDLED_SSL=on -DWITH_MRUBY=on -DCMAKE_INSTALL_PREFIX=%{_prefix} -DBUILD_SHARED_LIBS=on -DBUILD_SHARED_LIBS=yes .
It builds okay, but after the make install. I dont find any libh20.so* files. What is the correct flag?

I think I found it, I will confirm later. It requires libuv > 1.0 to create shared libraries.

Which CMake version did you use ? I didn't get such error with CMake version 3.6.1.

Fixed, i was having a typo in the libuv.pc file. I can confirm you must have libuv-devel in order to create the .so files

I have recently used cmake -DBUILD_SHARED_LIBS=ON .. to build shared lib (libh2o-evloop.so.0.11.4) for h2o-2.0.4 on ubuntu 16.04, with no libuv installed. My cmake version is 3.5.1 (comes with ubuntu).
