GCC2 compilation failure under Ubuntu Linux 10.04 (Lucid).

[bga]

today I tried to compile Haiku under Ubuntu 10.04 (64 bit) using the following configure command:

linux32 ../haiku/configure --alternative-gcc-output-dir ../haiku-gcc4 --build-cross-tools ../buildtools --include-gpl-addons --include-patented-code --target=haiku --use-gcc-pipe --use-32bit --use-xattr

At some point it failed when trying to generate a info file with makeinfo:

gcc -o c++filt -DCROSS_COMPILE -DIN_GCC     -O2 -U_FORTIFY_SOURCE  -DHAVE_CONFIG_H  \
	  cxxmain.o underscore.o obstack.o        ../libiberty/libiberty.a

Too many errors!  Gave up.
make[1]: ** [cpp.info] Erro 4
make[1]: Saindo do diretório `/haiku-dev/haiku-gcc2/cross-tools-build/gcc/gcc'
make: ** [cross] Erro 2
ERROR: Building gcc failed.

it seems the problem is that the generated makeinfo is, somehow, broken. For instance, the first error says:

/home/bga/haiku-dev/buildtools/legacy/gcc/gcc/cpp.texi:10: Bad argument to `end', `direnryy', using `direntry'.

But line 10 of cpp.texi is:

@end ifinfo

The previous line is:

@end direntry

Which is probably what it refers to, but notice that while the file has "direntry", the error message is mentioning "direnryy".

Any ideas about this one?

Replying to bga:

Any ideas about this one?

No, sorry. As a solution, since the documentation is utterly superfluous when building the cross-compiler, you could look whether there's an option to disable it, or, if not, hack the gcc build system to always not build it in cross-compilation mode.

[bga]

Oh well... I installed the 32 bit version and, then, it worked. I will try to investigate it a bit more.

[Shisui]

I got the same error when re-configuring my Haiku build under Ubuntu 10.04 x64. The first time, I was able to bypass this error by replacing the generated makeinfo by a symlink to /usr/bin/makeinfo. This time, I search in the makeinfo sourcecode what was going wrong.

A bad strcpy() call is involved, which tries to copy a buffer over himself, which is strongly discouraged since it may or may not work, depending on the implementation (I believe the strcpy implementation in the x64 version of libc can't handle buffer overlap).

The above patch correct this strcpy() call. :-)

edit: The patch is to be applied to buildtools/legacy/gcc/texinfo/makeinfo/makeinfo.c

[bonefish]

Shisui, thanks for the patch! It is unnecessarily complicated, though. The to be replaced strcpy(string, string + x) is semantically equivalent to memmove(string, string + x, strlen(string + x) + 1), with the latter handling the potential overlap correctly.

Bruno, assigning to you. If you can verify this fixes the problem, please apply the change and close the ticket.

[bga]

Will do this tomorrow. Thank you both for your help. now i just need a working Intel Extreme driver. :)

[bga]

I went ahead and tried the fix. It worked.

Fixed in hrev37574.
