Can not build Rmath

[simonbyrne]

looks like you're using a non-system gcc. You should be able to do:

make -C ~/.julia/v0.6/Rmath/deps/src/Rmath-julia-0.2.0/ USECLANG=1

(we should probably make that the default on OS X anyway)

[simonbyrne]

Can you try running the script from the package directory (/Users/mcawte/.julia/v0.6/Rmath)?

[mcawte]

The build.jl script?

[simonbyrne]

Actually, can you run

make -C ~/.julia/v0.6/Rmath/deps/src/Rmath-julia-0.2.0/

[mcawte]

Sure, the result is

Mcawte:Rmath mcawte$ make -C ~/.julia/v0.6/Rmath/deps/src/Rmath-julia-0.2.0/
/Applications/Xcode.app/Contents/Developer/usr/bin/make -C src
gcc  -Wall -O3 -fPIC -DMATHLIB_STANDALONE   -std=gnu99 -I../include -DNDEBUG -c bd0.c -o bd0.o
make[1]: *** [bd0.o] Segmentation fault: 11
make: *** [all] Error 2
Mcawte:Rmath mcawte$ 

[simonbyrne]

Hmm. Can you try:

make -C ~/.julia/v0.6/Rmath/deps/src/Rmath-julia-0.2.0/ CFLAGS=-v

[mcawte]

Same error unfortunately

Mcawte:Rmath mcawte$ make -C ~/.julia/v0.6/Rmath/deps/src/Rmath-julia-0.2.0/ CFLAGS=-v
/Applications/Xcode.app/Contents/Developer/usr/bin/make -C src
gcc  -Wall -O3 -fPIC -DMATHLIB_STANDALONE -v  -std=gnu99 -I../include -DNDEBUG -c bd0.c -o bd0.o
make[1]: *** [bd0.o] Segmentation fault: 11
make: *** [all] Error 2

[simonbyrne]

does gcc -v work?

[simonbyrne]

also, what does which gcc give?

[mcawte]

Okay, so there is probably something wrong with my compiler?

Mcawte:Rmath mcawte$ gcc -v
Segmentation fault: 11
Mcawte:Rmath mcawte$ which gcc
/usr/local/bin/gcc

[ararslan]

Did you install GCC from Homebrew?

[mcawte]

Mcawte:Rmath mcawte$ brew list
ffmpeg		imagemagick	lame		libtiff		x264		xz
freetype	jpeg		libpng		libtool		xvid

Should it be using gcc through homebrew?

[mcawte]

make -C ~/.julia/v0.6/Rmath/deps/src/Rmath-julia-0.2.0/ USECLANG=1

That seems to have worked. Should I add USECLANG=1 into the build.jl file and then build from julia?

[simonbyrne]

That seems to have worked. Should I add USECLANG=1 into the build.jl file and then build from julia?

I think it should be sufficient to just run Pkg.build("Rmath").

Should it be using gcc through homebrew?

No. By default, /usr/bin/gcc on mac is actually a small wrapper around clang: I guess this is for compatibility reasons. You can also install GCC itself, which appears to have been done on your system at some stage, though it appears to be broken.

[mcawte]

Okay, I will change the path to the correct version of clang and get rid of this gcc install. Thank you for your time.
