cross-compilers available?

Hi,

Are the gcc cross-compilers that 0day uses available for download
somewhere on the internet?

I am currently using the cross-compilers from
https://mirrors.edge.kernel.org/pub/tools/crosstool/ but I am having
problems with MIPS cross-builds.

thanks.

yes, and you can have a check at https://download.01.org/0day-ci/cross-package/
which contains the cross packages we use.

Thanks

Well, that was disappointing.  I am seeing the same errors with
the 0day compilers that I did with the crosstool builds from kernel.org.

I conclude that the problem is in asm (assembler language) processing
instead of gcc, but please correct me if you know better than I do
(which easily could be).

With either gcc cross-compiler for MIPS (32-bit), I see:

{standard input}: Assembler messages:
{standard input}:1974: Error: found '(', expected: ')'
{standard input}:1974: Error: found '(', expected: ')'
{standard input}:1974: Error: non-constant expression in ".if" statement
{standard input}:1974: Error: junk at end of line, first unrecognized character is `('

and also
/home/rdunlap/crosstool/gcc-9.3.0-nolibc/mipsel-linux/bin/mipsel-linux-ld: /lib64/libc.so.6: version `GLIBC_2.27' not found (required by /home/rdunlap/crosstool/gcc-9.3.0-nolibc/mipsel-linux/bin/mipsel-linux-ld)

Hm, it seems that I am using libc 2.26. Guess I will try to find 2.27
or later although that seems (to me) to be unrelated to the Assembler
errors that I am seeing.


Thanks.
