Hello All, Here is the small description of the issue:
OS: RHEL 6.6 cmake ver. 2.8.12.2 gmake ver. 3.81 I launch the build and got the following error: make build_release -j5 make[1]: Entering directory `/home/igor/build_root/release_target' make[1]: warning: jobserver unavailable: using -j1. Add `+' to parent make rule. So, make[1] reported that's job server is unavailable. Here is typical process subtree of my make: root 1731 0.0 0.0 66688 580 ?
