Hi, per posix.mak:



I just tried:

make std/algorithm/comparison.test

and it seems to build and run all tests. Before I look into it closer, 
any known change that affected this? Thanks.

Note that we only run unittests of std/algorithm/comparison.d, but need
to build Phobos. If you don't change any other parts of Phobos, you can
typically get away with

dmd -unittest -main -run std/algorithm/comparison.d

Though while it sometimes might work with the latest relase, on my
system I get linker errors as things have changed:

---
comparison.o:std/algorithm/comparison.d:function
_D3std4math__T11approxEqualTdTdTdZQuFNaNbNiNfddddZb: error: undefined
reference to '_D3std4math4fabsFNaNbNiNedZd'
comparison.o:std/algorithm/comparison.d:function
_D3std4math__T11approxEqualTdTdTdZQuFNaNbNiNfddddZb: error: undefined

comparison.o:std/algorithm/comparison.d:function
_D3std4math__T11approxEqualTdTdTdZQuFNaNbNiNfddddZb: error: undefined
reference to '_D3std4math4fabsFNaNbNiNedZd'
collect2: error: ld returned 1 exit status
---

So you'll need to make sure to use the latest DMD which by default
includes your freshly built Phobos library. Then you don't need to
rebuild Phobos constantly.

Cheers,

Seb
