Error message: sysinfo.c:18:24: fatal error: linux/user.h: No such file or directory, compiling Gccgo on Fedora 11 i386.
I came across this error message after following the instructions on the Gccgo website,
1) install any dependancies ( kernel-devel, kernel-headers, the usual compilations tools including gcc )
2) Configure the source ../gccgo/configure --enable-languages=c,c++,go
3) Make and then the error :
sysinfo.c:18:24: fatal error: linux/user.h: No such file or directory
The only other link in Google for this error is on the Golang-Nuts Group list / website.
Having read this page I am testing by installing more possibly silent or otherwise missing dependancies and recompiling before I start changing the code at all. I will update the page with more information shortly ...
So after some tinkering i decided to find out where it expected to include these files, and found them using locate. ( on my Fedora 11 box, it was searching /usr/local/src )
[root@f11 include]# cp /usr/src/kernels/2.6.30.8-64.fc11.i586/arch/x86/include/asm/user_64.h asm/
I repeated the solution, only to come accross a new error:
libgo/syscalls/sysfile.go sysinfo.go -fPIC -o .libs/libsyscall.a.o

So back to the drawing board, I suspect I should do an SVN update, make sure I have the latest src, rm -fr the source tree, and start again. I might have to work on the config script, look in more detail at what its doing. I am pretty sure my environment is not setup well for gccgo and its not that it does not compile. I am not afraid to change the code, but it complicates troubleshooting if you do mess with it :) Other people do report sucess compiling, I must do more research and try again.
