texlive-bin won't build correctly with clang

[mike-savory]

I had a different issue with #30849: libzzip won't build correctly with clang

Clang on Lion (Clean install of Lion, MacPorts 2.0.1 from dmg, and Xcode 4.2 (4D151a)

First Error seems to be

Poppler would seem to be installed

$ sudo port installed | grep popp

poppler @0.16.6_0 (active)

poppler-data @0.4.4_0 (active)

[mike-savory]

Confirmed as a clang issue. Reverted to Xcode 4.1, build still failed with clang but worked with configure.compiler llvm-gcc-4.2 added to the portfile

[drkp (Dan Ports)]

r82984 forces llvm-gcc instead of clang for now, but we should still figure out what it'll take to make it build with clang at some point.

[jmroot (Joshua Root)]

Should just need -I${prefix}/include. Clang doesn't handle CPATH: ​http://llvm.org/bugs/show_bug.cgi?id=8971

[drkp (Dan Ports)]

It really needs to come after the -I options, though, which is why we're using C_INCLUDE_PATH instead of -I. It doesn't look like clang supports -isystem either.

[drkp (Dan Ports)]

...or maybe it does, it's just not listed in the manpage.

[drkp (Dan Ports)]

Fixed and reenabled in r83018.

For those following along at home, clang lists C_INCLUDE_PATH in its manpage but doesn't actually support it. It supports -isystem but doesn't list that in the manpage. Go figure.
