alliance: non-void function 'elpLotrsShrink' should return a value

[yannick.heinrich@…]

The port does not compile on Mac Os X Lion

[ryandesign (Ryan Carsten Schmidt)]

The first error in the log is:

:info:build elp.c:252:1: error: non-void function 'elpLotrsShrink' should return a value [-Wreturn-type]

I also see you're using clang. This could be because clang is more strict. Have you tried using a different compiler? Let us know if a different one works better and we can fix the port.

I tried with 'sudo port install -d alliance configure.compiler=gcc' it compiles but not linked :( I join the log files. Some classes referenced in libU.a are not found

I confirm I get the same error of the reporter when using clang on 10.7.2 .

Switching to llvm-gcc-4.2 gives a symbol not found error in an archive library

Using apple-gcc42 compiler comletes the build just fine.

I think we should force apple-gcc42 on Lion and report the issue with different compilers upstream.

[yannick.heinrich@…]

I tried to force with sudo port -d install alliance configure.compiler=apple-gcc42 but it tells me that the value is incorrect. Itried with sudo port -d install alliance configure.compiler=apple-gcc-4.2 but I get the same linking error :(

Replying to yannick.heinrich@…:

I tried to force with sudo port -d install alliance configure.compiler=apple-gcc42 but it tells me that the value is incorrect.

The port name is apple-gcc42, the configure.compiler value to trigger its use is apple-gcc-4.2 so the option becomes configure.compiler=apple-gcc-4.2.

I tried with sudo port -d install alliance configure.compiler=apple-gcc-4.2 but I get the same linking error :(

Please clean the port, clear terminal buffer and re-run

sudo port install foo configure.compiler=apple-gcc-4.2 configure.cxx=g++-apple-4.2

save the output and attach it.

Notice the C++ compiler option as per the link Ryan provided, alliance is using it.

[yannick.heinrich@…]

It compiles fine and seems to work good :) Thanks your great help !

Committed r89248, ticket closed.

This has been further edited in r89292, now it will compile with clang as well. You may want to uninstall apple-gcc42 if not needed.
