Error building GCC

[0xDani]

Hello!

/* Sorry for my english, it isn't my native language */

I'm following this wiki article in order to build GCC 4.6.1, enabling C and C++, but in this step:

Code: Select all

make all-gcc

the compiler throws me some errors:

gcc -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -DHAVE_CONFIG_H -I. -I. -I../../gcc-4.6.1/gcc -I../../gcc-4.6.1/gcc/. -I../../gcc-4.6.1/gcc/../include -I../../gcc-4.6.1/gcc/../libcpp/include -I../../gcc-4.6.1/gcc/../libdecnumber -I../../gcc-4.6.1/gcc/../libdecnumber/dpd -I../libdecnumber gtype-desc.c -o gtype-desc.o
gtype-desc.c:8868:18: error: el valor del subíndice no es ni matriz ni puntero ni vector
gtype-desc.c:8987:36: error: el valor del subíndice no es ni matriz ni puntero ni vector
gtype-desc.c:9071:31: error: el valor del subíndice no es ni matriz ni puntero ni vector
gtype-desc.c:9092:31: error: el valor del subíndice no es ni matriz ni puntero ni vector
gtype-desc.c:9099:31: error: el valor del subíndice no es ni matriz ni puntero ni vector
gtype-desc.c:9106:31: error: el valor del subíndice no es ni matriz ni puntero ni vector

As you can see, error messages are in Spanish (sorry), here is my translation, that might be incorrect:

error: index value is neither a matrix nor a pointer nor a vector

I actually know C programming, but I'm not gonna get through the whole code to try to fix it.

Could you help me?

Its a known issue.

Basically, use the patch there or a more modern version of gcc.

Regards,

Thanks for the help! I'll download a newer version of GCC.

Set the LC_ALL=C environmental variable and build your gcc with --disable-nls to be sure to have english error messages. If you don't put in some effort so we have proper error messages, it's harder for us to help you and it'll be be harder to get help.

But yeah, there was a few minor releases of gcc that didn't bootstrap correctly with newer gcc versions, but the later patched versions fixed the problems.

Yes, I've built gcc and g++ with --disable-nls in order to get errors in english, as it was recommended in the wiki.

Finally I downloaded the 4.7.0 version and could build it succesfully.

I recommend you use the newest minor version of every major release. For instance, if you wish to use the gcc 4.7.x series, I recommend you use gcc 4.7.3. I normally recommend you use the newest compiler. I just updated the cross-compiler tutorial (http://wiki.osdev.org/GCC_Cross-Compiler) heavily, and added a tutorial if you wish to update your system compiler (http://wiki.osdev.org/Building_GCC).
