在Mac上将GCC 4.4与NetBeans集成

Question

I've got NetBeans 6.9 installed on a Mac OS Snow Leopard. Also, I installed gcc 4.4 through MacPorts in order to experiment with C++0x. I believe, by default NetBeans uses the standard Apple gcc 4.2 compiler which is invoked through a g++ symlink found in /usr/bin .

My question is: how can I still use the new compiler?

I tried creating a new Tool Collection in NetBeans by specifying the default directory to /opt/local/bin which is where gcc 4.4 is present. But this caused error messages, ie No compiler sets were found... . I also tried modifying the existing GNU Tool Collection by selectively specifying the C++ Compiler command as /opt/local/bin/x86_64-apple-darwin10-g++-mp-4.4 . However, this caused build errors which I didn't even understand. Any ideas appreciated.

Answer 1

What you describe here, adding a new tools chain with that path, just should work with gcc 4.4, see here http://forums.netbeans.org/post-70004.html
Are you sure nothing is missing in your GCC 4.4 ?

The only missing step is to click "Reset Settings" help in Code Assistance tab after creating the tool chain, to make sure that code assistance picks the new headers.

Answer 2

This works for me:

Create a directory for your toolchain:

mkdir -p ~/toolchains/gcc-4.4-mp/bin

then link gcc's binaries into the bin directory

cd ~/toolchains/gcc-4.4-mp/bin
ln -fs /opt/local/bin/*-mp-4.4

and give gcc's tools their unmodified names back:

for x in *-mp-4.4 ; do ln -fs $x ${x%-mp*} ; done

or

for x in *-mp-4.4 ; do mv $x ${x%-mp*} ; done

Now you can add ~/toolchains/gcc-4.4-mp/bin as a new Toolchain Collection .

Answer 3

Here's the "easiest" solution. Edit your PATH environment variable and then open NetBeans.

sudo port install gcc_select
sudo gcc_select mp-gcc44

# tcsh:
setenv PATH /opt/local/bin:${PATH}

# bash:
PATH=/opt/local/bin:${PATH}; export PATH

# And then:
open /Applications/NetBeans.app

You should be good to go after that unless NetBeans (uses an absolute path to the compiler).
