qt-3.0.4.1 compilation error

[Roy]

I am upgrading from kde2 to kde3.

I get an error when my computer tries to compile QT.

There are more warnings. All saying the same sort of thing. Then it dies with that error.

I have been trying to fix this problem for weeks. So if you know what is wrong please tell me.

I'm getting the same error here. It looks like it's a clash of some sort between several different kernel header files.

Thats what I thought. But I uninstalled all the old versions of everything. I even tried to uninstall the linux-headers. Of course that didn't work.

[jtanner]

Did you try unmerging kde 2.2.2?

That didn't work

Just a few thoughts:

Just wondering, did you explicitly unmerge the headers, and re-emerge them? Have you applied any third party patches, or are you using low_latency/preemptive patches? Could you quote some of the line numbers referenced in some of the include files? For example, the inline function read_lock is defined as such in my spinlock.h:

Code: Select all

static inline void read_lock(rwlock_t *rw)

which is different to yours (not sure if kernel config options can affect this or not). What version does emerge -s linux-headers say you have installed? I am using 2.4.18 - I noticed that r1 & r2 revisions are available but emerge uses stock 2.4.18 by default.

Also, I am using the newest binutils because I want to use the new combreloc performance enhancements (and presumably, bugs have been fixed from older versions). Have no idea whether it's considered "production" quality or not (wish the Changelogs would tell you), but you could give it a whirl - you have to use ebuild not emerge. And try toning down your compiler options in make.conf if you are using a lot of nutty optimisations - I used to use them, but nowadays I only add omit-frame-pointer, recompiled everything and things have been a lot less problematic from then (and not noticeably slower). Excessive optimisations can create broken binaries (which is really bad if some of these binaries are your core system tools) ...

I tried to everge 3.0.4.1 and it said blocked by package mask. Try 3.0.4-r1

It isn't that. I can't merge any version of QT anymore. Not even 2.3.2

I explicitly unmerged the linux headers and then remerged them. 2.4.18 is the only version of the headers installed.

I haven't applied any patches myself. I've only used the kernel supplied with gentoo. I'm using gentoo-sources 2.4.19-r5

My read_lock function looks like this:

Code: Select all

static inline void read_lock(rwlock_t *rw)
{
#if SPINLOCK_DEBUG
        if (rw->magic != RWLOCK_MAGIC)
                BUG();
#endif
        __build_read_lock(rw, "__read_lock_failed");
}

Line 192 is:

Code: Select all

        __build_read_lock(rw, "__read_lock_failed");
