Re : [GCC front end] trying to install sample_fe but fail in make

Hello Andi,

thank you for your answer. 

I modified the sfe1.c as you suggested. previous error disappears
but I get 2 other errors generated while calling make bootstrap

I am calling ./configure after creating an other directory (not related in the source directory) named gcc-obj.
this time, I think the error comes from the driver (gsfe); xhnich line should I modify ;)
thank you very much

Hey,

Thanks for trying this :-) And thanks for catching this silly mistake!

Generally, you should follow the install instructions on
http://gcc.gnu.org/install/ and NOT call configure from the source
directory, but from a separated build directory.

Yes, I think that as well. You could possibly fix this by changing line 24
of sfe1.c

from

struct GTY(()) lang_identifier

to

struct lang_identifier GTY(())

But, I'm not totally sure if this version of sample_fe will work anyway
with your version, because I just tested it with 4.4.x and you seem to
compile a 4.1.0 version. If you for some reason require to use 4.1.0, then
please continue trying and let me know if you face further problems.
Otherwise, I would recommend using a 4.4.x. I'll upload a 4.5.0-based
version this weekend, so that you could also use gcc-4.5.0 for your
experiments.

I'll update the web page with a modified version ...

Best regards,
Andi
