emerge matroxset would give me: gcc -c -o matroxset.o matroxset.c matroxset.c: In function `main': matroxset.c:95: error: syntax error before '[' token matroxset.c:101: error: syntax error before '[' token matroxset.c:104: error: syntax error before '[' token matroxset.c:110: error: syntax error before '[' token make: *** [matroxset.o] Error 1 I tracked down the error but don't know the correct fix. Here's the deal: In /usr/include/asm/ioctl.h this is defined: /* provoke compile error for invalid uses of size argument */ extern unsigned int __invalid_size_argument_for_IOC; #define _IOC_TYPECHECK(t) \ ((sizeof(t) == sizeof(t[1]) && \ sizeof(t) < (1 << _IOC_SIZEBITS)) ? \ sizeof(t) : __invalid_size_argument_for_IOC) This fails and if i remove the first check, like this: #define _IOC_TYPECHECK(t) \ (( sizeof(t) < (1 << _IOC_SIZEBITS)) ? \ sizeof(t) : __invalid_size_argument_for_IOC) It compiles and should in most cases do the same thing. This is probably not a good fix but it's at least something. Reproducible: Always Steps to Reproduce: 1. emerge matroxset 2. 3.
Created attachment 45800 [details, diff] the patch Here's a patch if you want that for some reason. I guess the sizeof-check should still be done in some way though. Should i forward this to the linux-devel list?
No comment on this?
This is a kernel patch. Kernel team needs to check on this.
It's not kernel. Its headers. Which headers are in use?
I use sys-kernel/linux26-headers-2.6.8.1-r1
Try linux-headers-2.6.10 please (not linux26-headers).

Error: The above package list contains packages which cannot be installed !!! on the same system. --- Well that package was masked. Is this due to me using an old profile? Anyway, i really dont want to go through a lot of hassle to get this working. Especially since i don't use matroxset anymore.
I just emerged it with linux-headers-2.4.19 and linux-headers-2.4.22 and linux-headers-2.6.10 and it worked fine for me. So it's a header issue with the linux26-headers. I am closing this since the original poster no longer uses matroxset.
