In the portfile: configure.compiler gcc-4.2

If the port requires, apple-gcc42 then it should be in the build depencies? Attached is a patch which fixes this issue.

[jm@…]

The patch does not solve the issue. Can you help?

[jm@…]

I could compile automoc with gcc4 and remove the requirement for gcc42. I don't know MacPorts enough to judge if this fix is correct.

The reason gcc42 is set as the compiler for the kde ports is because gcc4 won't work and gnu's gcc 4.2 doesn't work either. So the fix, would be to update the apple-gcc42 port to the latest version. I'm trying to get this working in ticket #16666.

[illogic-al@…]

btw, all these patches aren't necessary. All the common building bits are in a port group so only one file would need to be patched. See trunk/dports/_resources/port1.0/group/kde4-1.0.tcl​ :-) If you get this working, that is probably the only file you would need to patch.

[jm@…]

I changed the file on my local svn checkout files. Now how to use them for testing locally?

[jm@…]

Please find attached a patch which adds gcc42 build requirement to kde4-1.0.tcl. It is quite a trivial patch for consistency. Then we may decide to replace gcc42 by mac-gcc42. This is becoming quite important and it would be nice to fix Kde4 compilation rapidly.

[jm@…]

According to Kde team, KDE4 should be able to compile using gcc42. Now, how do I apply the kde4port patch locally to testing purpose?

[illogic-al@…]

Replying to jm@…:

It should already be applied (how would you have made a patch otherwise)? If you mean you want it applied in macports you need to prove to me that this actually works. Normally I'd test it myself but I'm still working on other things atm, and am not willing to break things for everybody. So, prove that using gcc42 both a) compiles and b) produces programs that actually run and i'll make the change.

[jm@…]

I am stuck trying to prepare packages for Kdenlive (​http://www.kdenlive.org)
Tuning compilation parameters in trunk/dports/_resources/port1.0/group/kde4-1.0.tcl​ is important.
Can you help us? We are stuck on kde4 and this is normal.

[jm@…]

Okay. I was able to patch automoc to use macports gcc42. Then I modified kde4-1.0.tcl and I am recompiling the buzz. Stay tuned.

[sergio.roa@…]

Hi! Please take a look at this ticket: #18471. I managed to install the above mentioned libraries and kdebase4-runtime

[illogic-al@…]

What's the word jm? What happened with using macports gcc42? Can this ticket be closed?

[jm@…]

This bug only affect MacOs 10.4, which offre gcc4.0.
apple-gcc-42 compiles fine. Now there are two issues:

• apple-gcc42 does not correspond to any compiler option. I tried apple-gcc-42 without success. So this should be solved first.
• automoc compiler should be configured to use a specific compiler.
• Then trunk/dports/_resources/port1.0/group/kde4-1.0.tcl​ should be partched to reference apple-gcc-42

I think the way to configure apple-gcc-42 is this

configure.compiler  apple-gcc-4.2

See UsingTheRightCompiler

Does the apple-gcc-4.2 port build a c++ compiler now?
