Hello everybody,
For a while I've been trying to compile gcc (7.2.0) by following this site's tutorial (Hosted GCC Cross Compiler) and I'm blocking when compiling gcc:

Code: Select all

make all-gcc

I get this error:

Code: Select all

Do not hesitate to ask me for more details if necessary
How to solve this problem? Thank you!

PS: Sorry for my bad English but i'm french

Most likely your config.gcc or one of your target header files (i.e. gcc/config/foo.h) is broken.

Does tm_file in your config.gcc include i386/att.h and elfos.h?

EDIT: I'm assuming that you're building GCC for your own OS' user space and not a generic ELF compiler (?).

Yes, I'm building GCC for your own OS' user space. I tried with gcc 6.4.0 and it works perfectly, so I'm going to use GCC 6.4

. But I don't now why it doesn't work with gcc 6.4 (I did the same things as with gcc 7.2)
But thank you for your response.

EDIT: i'v found the att.h: it's ok but i's located in gcc/config/i386: i try to copy its in gcc and rebuild

The file should be in gcc/config/i386, that is correct.

Your tm_file variable should include it though.

I'm using a GCC 7 port on my OS, that GCC version should not be a problem.

OK, my file include ASM_GENERATE_INTERNAL_LABEL in tm_file but i does'nt work... I try to redownload source ,remodify and recompile
