Hi All,

today I tried a fresh install with

git clone git://github.com/JuliaLang/julia.git  
cd julia  
git checkout v0.6.1  
make

…  
ld: library not found for -lSystem  
collect2: error: ld returned 1 exit status  
make[4]: \*\*\* [testlsame] Error 1  
make[3]: \*\*\* [lapack\_install] Error 2  
make[2]: \*\*\* [netlib] Error 2  
\*\*\* Clean the OpenBLAS build with ‘make -C deps clean-openblas’. Rebuild with ‘make OPENBLAS\_USE\_THREAD=0’ if OpenBLAS had trouble linking libpthread.so, and with ‘make OPENBLAS\_TARGET\_ARCH=NEHALEM’ if there were errors building SandyBridge support. Both these options can also be used simultaneously. \*\*\*  
make[1]: \*\*\* [scratch/openblas-85636ff1a015d04d3a8f960bc644b85ee5157135/build-compiled] Error 1  
make: \*\*\* [julia-deps] Error 2

which cannot be solved (I tried the suggestions). I have MacOS 10.12.3, XCode 9.01 with all bits and bobs, gfortran is GNU Fortran 7.2.0 form homebrew.

I fail to understand what is going on

I was trying to build from source last night on Linux, and didn’t realize there was now a v0.6.1. But I had the same error.  
I got around it by cloning, building, and installing [OpenBLAS](https://github.com/xianyi/OpenBLAS). Then returning to Julia, creatrf the file Make.user with the following lines:

```julia
USE_SYSTEM_BLAS=1
LIBBLAS=-lopenblas
LIBBLASNAME=libopenblas

```

as described in Linux troubleshooting. Even though you’re on a Mac, given that your error is in building OpenBLAS, if you can just get it on your system and then use system BLAS you should be fine.

because I am lazy, and I do mean it, I was wondering whether there is an option that does not require me to install my own OpenBLAS (or use OSX supplied one, assuming it supplies one), mostly because I would have to baby the darn thing forevermore rather than just clone the latest stable release and `make`. Do not get me wrong, I think you are suggesting a good fix, but let’s see if a less work approach comes up.

Try adding a `Make.user` file in the your julia directory after `git checkout v0.6.1` and before running `make` containing just:

```julia
OPENBLAS_TARGET_ARCH=HASWELL

```

or if your Mac is super old, maybe:

```julia
OPENBLAS_TARGET_ARCH=NEHALEM

```

instead. Presumably putting those options in the command line as suggested is equivalent, but maybe not?

I tried this (the other option has been already tried and does not work) and it did not work.

I gave up and went with the brew cast approach – life is too short for this kind of malarky.
