Re: [CMake] Parallel jobs failed for cmake

2015-12-13 Thread Igor Sobinov

 Hello Bill,

Thanks, that's clear.

So, If I write in makefile


build_release: $(RELEASE_DIR)
    @cd $(RELEASE_DIR); $(MAKE) release

I got an error

Also if I write build_release: $(RELEASE_DIR)
    $(MAKE) release -C   $(RELEASE_DIR)

I got an error too

But this is successfull command:
# cd $ RELEASE_DIR; make release -j10

Why make doesn't support jobs for subdirs?

Re: [CMake] Parallel jobs failed for cmake

2015-12-11 Thread Igor Sobinov

 Hello Bill,

yes, make release is a custom command but that's not important.
I do the following:
# cd  /home/igor/build_root/release_target
#  make release -j5

and again got an error

make[4]: warning: jobserver unavailable: using -j1.  Add `+' to parent make 
rule.

All Makefiles in  release_target are auto generated by cmake, there are no any 
user's code.

Unfortunately I can't send you  CMakeLists.txt(

[CMake] Parallel jobs failed for cmake

2015-12-09 Thread Igor Sobinov

 Hello,

I compiled cmake based project with -jN option, but failed: I got the following 
error:

make[4]: warning: jobserver unavailable: using -j1.  Add `+' to parent make 
rule.

How to make cmake to compile with multiple targets?

Bye, Igor

Re: [CMake] Parallel jobs failed for cmake

2015-12-09 Thread Igor Sobinov

 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:
