Hello,

Vexing problem: running suse 9.1 pro. When compiling programs from source, i get an error 'errno.h undeclared'. I check the source files and sure enough, '#include <errno.h>' is up there at the top of the file. I've tried: restoring a fresh copy of errno.h to /usr/include from /usr/include/bits and from ~/src/linux/include. This happens with most of the programs i try to install from source.

I've also tried using many different compiler options offered by the program(s) in question to no avail. I'm using the GCC compiler what came with suse 9.1 pro. I've installed every other compiler as well out of sheer desparation.

I'd welcome any suggestions because i'm in the dark.

what are you trying to install? Suse is an rpm based distro and I'd try to find a rpm for the software instead. I mean it *is* possible, but a lot of times the file path info is wrong or it tries to put files in places or grab them from places that don't exist.

this ain't right !
header files are not spit out as undeclared
possibly a variable or a function is undeclared within errno.h

you have to give us exact error output from trying to compile a specific program

that was a very wrong thing to do

the kernel source includes are not at all the same include files used in the user space kernel interface
those files have to match exactly the ones used to compile glibc

that's i bet the problem

time to reinstall glibc-devel

I appreciate the suggestions. As I said in the original post, the problem happens with MANY programs i try to install from source (50% of them or more). I'm only trying to compile from source the programs i cannot find in rpm form or binaries for.

Every change that i've made had no effect. I have re-installed glibc twice after making changes with no effect. I'm carefull to reverse the changes I do make if they are ineffective. I've also re-installed the gcc compiler and related packages. Again: no change. Same !&#^@&$*&# error.

Right now i'm thinking of updating the gcc compiler. The version that shipped w/ suse 9.1 pro was 3.3.3.

This is a general problem that i'm having so, after pursuing as many avenues as I could, I'm coming here. In other words, i'm pretty frustrated....

Thanks again.
