[17:01] are there any differences between whats packaged in Ubuntu Gnome 16.4.3 and whats packaged in Ubuntu 16.04.3 (in terms of development packages) [17:03] for some reason i have a project which does not build in Ubuntu Gnome 16.04.3 but builds fine Vanilla Ubuntu 16.04.3 [17:04] G__81: no, you probably don't have the same dependencies installed on those computers [17:05] my source tree looks for protobuf-c and it fails. But i have the package installed in Ubuntu Gnome [17:05] i have installed the necessary packages though [17:06] I don't work with protobuf but do you have the *development headers package* installed? [17:06] I guess that's libprotobuf-c-dev [17:07] i have build-essential installed [17:13] is there anything else to be installed? [17:15] I generally start with sudo apt build-dep packageNameI'mTryingToBuild [17:23] thanks for your help jbicha its pkg-config that solved the issue.I guess pkg-config is installed in 16.04
