I usually work on release+asserts build, which is much faster and doesn't require that much RAM as Debug/RelWithDebInfo build. I only build debug when I need it :) Also lowering jobs for linking is very helpful when building with debug/LTO etc. On Tue, Sep 6, 2016 at 3:37 PM, Alexandre Isoard via llvm-dev < llvm-dev at lists.llvm.org> wrote:> And again... > LLVM_BUILD_LLVM_DYLIB:BOOL=ON > LLVM_LINK_LLVM_DYLIB:BOOL=ON > > This one is the good one... maybe. > > On Tue, Sep 6, 2016 at 11:35 PM, Alexandre Isoard < > alexandre.isoard at gmail.com> wrote: > >> That is because I mistyped it: >> LLVM_ENABLE_LLVM_DYLIB:BOOL=ON >> LLVM_LINK_LLVM_DYLIB:BOOL=ON >> >> On Tue, Sep 6, 2016 at 11:31 PM, Wink Saville <wink at saville.com> wrote: >> >>> On Tue, Sep 6, 2016 at 3:05 PM, Alexandre Isoard >>> <alexandre.isoard at gmail.com> wrote: >>> > LLVM_ENABLE_DYLIB >>> >>> Where/when/how do you specify LLVM_ENABLE_DYLIB and LLVM_LINK_DYLIB? >>> >>> I tried the following on the cmake command line: >>> >>> $ cmake -G Ninja .. -DCMAKE_INSTALL_PREFIX=/home/wink/opt/llvm >>> -DLLVM_ENABLE_DYLIB=true -DLLVM_LINK_DYLIB=true >>> >>> >>> And got: >>> ... >>> -- Performing Test CXX_SUPPORTS_NO_NESTED_ANON_TYPES_FLAG - Failed >>> -- Configuring done >>> -- Generating done >>> CMake Warning: >>> Manually-specified variables were not used by the project: >>> >>> LLVM_ENABLE_DYLIB >>> LLVM_LINK_DYLIB >>> >>> >>> -- Build files have been written to: /home/wink/foss/llvm.3.9.0/build >>> >> >> >> >> -- >> *Alexandre Isoard* >> > > > > -- > *Alexandre Isoard* > > _______________________________________________ > LLVM Developers mailing list > llvm-dev at lists.llvm.org > http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev > >-------------- next part -------------- An HTML attachment was scrubbed...

@prazek, can you share your cmake and or ninja command line? Actually are most people using -G Ninja for cmake as the documentation suggests?

I'll give it a try on the next build, txs again.

So with this cmake command line:
$ cmake -G Ninja .. -DCMAKE_INSTALL_PREFIX=/home/wink/opt/llvm
-DLLVM_PARALLEL_LINK_JOBS=2
And then running the build with "time ninja" took 21min:
$ time ninja
...
[3345/3481] Building C object

For maybe 20 seconds 100% of RAM was used while compiling
and then twice during linking it was 95-98% so overall not to bad.
I'm now going to try "time ninja check-all" I'll report back
what happens.
Thanks everyone for the assistance!!!
