Causes of Portage compile errors

I just finished installing Gentoo from the stage 1 tarball and, after a bit of experimenting, I have gotten it to work fantastically; it is definitely one of the coolest distros around. However, I have been experiencing very odd compile errors. For example, I don't have the exact mesage, but a while back I received a parse error when compiling libvorbis. Just now I tried again, without changing anything, and it works.

In general, what causes these types of errors, and what can I do about them? Please remember I have a total of 3 days of Gentoo experience.

Thanks in advance!

One thing that can cause compiling to fail at random points in the code is using -O3. Stepping it down to -O2 may fix it. There are some other flags that can cause trouble, but I think -O3 would be the best to check first.

If you don't have -O3 set, post your CFLAGS, maybe someone will notice something fishy.

Thanks for your help; I hadn't realized that was even set in the first place. Unfortunately, even when I changed it in make.conf from -O3 to -O2 I'm still having problems. When compiling gnome-base/ORBit2-2.6.2 (required for Gnome), I get this sort of thing:

Hi sploo22,

I can confirm this compile error of libvorbis (1.0-r4) too. I don't know how the first merge of this ebuild happened without these errors. I often made world updates in the last time and did not see any.

Unfortunately I had an evil boring evening and so I wanted to hear some music.

*bang*

... and xmms was dead

. I started it from terminal and repeated what went wrong. The output said "Ungültiger Maschinenbefehl" (eng. "invalid machine command"). So I tried to play this oggvorbis file with ogg123 - same message. Hmm.... why not looking into the system log? Yo! My big old friend grsec :lol:

killed everything that wanted to play oggvorbis with signal 4 (illegal instruction). The idea remerging libvorbis was near aaaand.....

The only thing I can think of is that the package was written for a version of gcc that's different from the one I have. Have you successfully compiled gnome? What CFLAGS and gcc version did you use?

Thanks for the bug report, I'll try changing that. But I'm not getting an internal compiler error, it's a syntax error. I'm compiling ORBit2-2.6.2, and it keeps giving me errors in a file called corba-defs.h (I think; I don't have the exact location handy as my Gentoo system is no longer directly connected to the Internet). The thing is, it doesn't even look like C code - it's got colons and =>'s and ['s and stuff all over the place.
