First of all, as you can see, the CXX env variable isn't honored (and g++ 3.4.3 is invoked instead 4.7.2).
Second, the correct linking should look like:

./gyp-sun-tool flock /home/emz/node.js-clean/node-v0.10.0/out/Release/linker.lock g++ -rdynamic -m64 -pthreads -Wl,-z,allextract -o /home/emz/node.js-clean/node-v0.10.0/out/Release/mksnapshot -Wl,-z,rescan /home/emz/node.js-clean/node-v0.10.0/out/Release/obj.target/mksnapshot/deps/v8/src/mksnapshot.o /home/emz/node.js-clean/node-v0.10.0/out/Release/obj.target/deps/v8/tools/gyp/libv8_base.a /home/emz/node.js-clean/node-v0.10.0/out/Release/obj.target/deps/v8/tools/gyp/libv8_nosnapshot.a -Wl,-lsocket -lnsl

Third, the -lrt library is missing.
With all of that, node.js can be built and ran on Solaris 10 (this is first of two crashes, but the same thing applies to the second one).

I saw a closed #2123 , the patch doesn't help any more - it complains about ar invocation (I guess first argument is missing).

So, this is still the issue. Since Solaris 10 will remain active as a platform for some time, it would be really nice to build node.js on it without problems.

The fact that solaris ld is used is not something either node or gyp can fix, I think - I'm reasonably sure it's hard-coded into the g++ binary. That said, if you build with make LINK=/path/to/gnu-toolchain-g++ it should work (same for CXX).

Why is librt needed? Is it because V8 calls sched_yield() in a couple of places? I can't take patches for that but if you submit it to (and get it landed in) upstream V8, I'll be happy to cherry-pick it.

[drook]

Nah, librt is needed because of the various sem_*() stuff, that's why linking fails without it.
Solaris ld is used because I compiled gcc 4.7.2 mentioning that I want to use it. By the way I thought that since it's the official linker for this platform, I have to use it, but seems like I was wrong.
Thanks.
