Root installation with gcc4.9.2 in osX 10.10.3

I have gcc installed via Homebrew:

[code]$ gcc --version
gcc (Homebrew gcc49 4.9.2_1 --with-fortran --with-all-languages) 4.9.2

Trying to install root using the following configuration:
./configure --prefix= --with-cc=gcc --with-cxx=g++ --with-ld=g++ --with-f77=gfortran --disable-cocoa --disable-vc --disable-fink --enable-builtin-freetype[/code]

It is not working. Could you please help?

I already see error in config.log

after make -j 4, I get the following error (included only the last few lines)

Looks like your linker and your gcc don’t work together. I don’t think we can fix that on the ROOT side… Maybe contact the homebrew GCC people? Or install a newer binutils from homebrew?
