Compile virtual box with gcc 4.7

[sergiomb]

Hi, has you may know for Fedora 17 will have packages rebuild with gcc 4.7, I try build VB with gcc 4.7, patch in attach.

but it will fail with a :

There are much more problem with gcc 4.7 of the current VBox code. We will adapt the code once gcc 4.7 has settled down a bit more.

Has package builder we also build kBuid , after user kBuid compile with gcc 4.7 I got this error on building virtuaBox

/usr/bin/kmk_sed: file /builddir/build/BUILD/VirtualBox-4.1.8_OSE/src/VBox/Runtime/common/err/errmsg.sed line 31: Unmatched [ or [^
kmk: *** [/builddir/build/BUILD/VirtualBox-4.1.8_OSE/obj/obj/Runtime/errmsgdata.h] Error 1
kmk: *** Deleting file `/builddir/build/BUILD/VirtualBox-4.1.8_OSE/obj/obj/Runtime/errmsgdata.h'
kmk: *** Waiting for unfinished jobs....

build virtualbox with same kBuild but that was build with gcc 4.6 I don't have this problem using kBuild-0.1.98-1.r1.fc17 works, using kBuild-0.1.98-2.r1.fc17 I got this error, with kmk_sed.
Any clue is appreciated
Thanks,

[Frank Mehnert]

It would be interesting if you could attach the file in question (errmsg.sed).

VirtualBox-4.1.8_OSE/src/VBox/Runtime/common/err/errmsg.sed

I will follow another tip from fedora-devel, I will send news soon. Thanks,

[Frank Mehnert]

Sorry, my fault. I actually meant to attach errmsgdata.h, see your error message.

[sergiomb]

the problem is exactly when is generate errmsgdata.h, if I got this error I don't have any errmsgdata.h. I try change sed regexp removing

extensions to regular expressions reefer : ​http://sed.sourceforge.net/sedfaq3.html

change [[:alnum:]] by [A-Za-z0-9] Alphanumeric characters

and [[:space:]] by [ \t\v\f] All whitespace chars,

but some white sapces aren't clean like EOL (end of line). and errmsgdata.h got errors, like miss " in EOL

Hi, this ticket report two problems.

First I believe that is solved in VirtaulBox-4.1.10,

But the second about kmk_sed that begins in #comment:2 , I will move it to ​http://svn.netlabs.org/kbuild , so please close this bug (I don't have permissions). I will open a new one for kmk_sed, if necessary.

[sergiomb]

the problem is after compile kBuild with gcc 4.7

​http://koji.fedoraproject.org/koji/packageinfo?packageID=7356

kmk_sed doesn't read well /builddir/build/BUILD/VirtualBox-4.1.10/src/VBox/Runtime/common/err/errmsg.sed
