3.3.10.2 installs on FreeBSD, but 3.3.10.4 does not about libv8

[courtland]

Trying to compile from source also breaks.

My first attempt resulted in this error:
Writing install/lib/scons-2.1.0/scons-2.1.0-py2.7.egg-info
Installed SCons library modules into install/lib/scons-2.1.0
Installed SCons scripts into install/bin

cp -r v8 build
patch -td build/v8 -i ../../fpic-on-linux-amd64.patch
Hmm... Looks like a unified diff to me...

The text leading up to this was:

|--- SConstruct

|+++ SConstruct

Notice that GCC_VERSION was not parsed/determined correctly and the arch flag passed to ../scons/install/bin/scons is missing.

If I make the following changes to the Makefile and manually specify GCC_VERSION and ARCH, I get a littler further.

If you manually build the gem from the master branch, you can get around this issue. We are preparing a new gem release but for now some user intervention is required.

Sorry about the trouble,

Thanks for the response. I did try to build the gem from the master branch and it seems to break. See my second post on this issue. Maybe I am missing something?

[fractaloop]

Hrm I don't know but I built a FreeBSD 8.2 image last night. I'll try to check it out during some spare cycles.

[mat813]

the main problem is that extconf.rb calls make where it should call gmake :-) (which is gnu make's name on FreeBSD)

[mat813]

hum, also, I noticed a small thing, the error actually is :
extconf.rb:13: uninitialized constant Gem (NameError)

adding require 'rubygems' at the top of the file fixes it.

[mat813]

Also, hum, on amd64, you need -fPIC, so adding the same than is done by the fpic-on-linux-amd64.patch to the freebsd section of the SConstruct file would be nice :-)

[cowboyd]

this should be fixed on master and with the switch to the GYP build
