Build fails on FreeBSD / Clang

[NuLL3rr0r]

It won't build on my FreeBSD 10.1 system due to lack of GCC presence. FreeBSD uses Clang as it's default compiler (clang, clang++ and clang-cpp) providing alternative symlinks such as (c++, c89, c99, cc, cpp) to remain compatible with GCC.

This is what I get after trying npm install

bcrypt@0.8.0 install /usr/home/babaei/dev/TaxiServer/node_modules/bcrypt
node-gyp rebuild

I fixed the issue by editing binding.gyp as follows (also I had to install sysutils/flock from ports):

{
'make_global_settings': [
['CXX','/usr/bin/clang++'],
['LINK','/usr/bin/clang++'],
],
'targets': [
{
'target_name': 'bcrypt_lib',
'sources': [
'src/blowfish.cc',
'src/bcrypt.cc',
'src/bcrypt_node.cc'
],
'include_dirs' : [
"<!(node -e "require('nan')")"
],
'conditions': [
[ 'OS=="win"', {
'defines': [
'uint=unsigned int',
],
}],
],
}
]
}

Is there anyway to make clang the default compiler on FreeBSD systems? cause putting cc and link settings in conditions section won't work.

This is a node-gyp issue. Please search the node-gyp repo for how to do this or create an issue there.

The cause is gyp itself which defaults to g++. a good workaround is:

export CXX=clang++
npm install --clang=1

Thanks @springmeyer it solved the issue ;)
Unfortunately, most developers are so much used to Linuxism. Why should someone assume the compiler is always gcc/g++ ? or Bash resides in /usr/bin/bash while the shebang line can be written like this #!/usr/bin/env bash in a crossplatform way.
I'll open an issue on node-gyp project.

[springmeyer]

This has nothing to do with linuxism. Freebsd used to use g++ and gyp has not caught up to the clang++ change because https://code.google.com/p/gyp/issues/detail?id=251 has not been landed. Note: this is a gyp issue and not node-gyp. Once gyp itself fixes this then all node-gyp needs to do is update to the latest gyp version.
