3.3.10.2 installs on FreeBSD, but 3.3.10.4 does not

[courtland]

Something seems to have broken between the .2 point release and .4 that breaks installing the gem under FreeBSD.

Trying to compile from source also breaks.

My first attempt resulted in this error:

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:

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
