malloc error when compiling insn-attrtab.c

malloc error when compiling insn-attrtab.c

[Jens Bauer]

Hi,

I'm having so much trouble compiling gcc-4.6.x (4.6.1, 4.6.2, 4.6.3).

A malloc error occurs when I try to compile 'insn-attrtab.c'.

Here's the last output from my build.

My computer is a PowerMac G5, I'm running Mac OS X 10.5.8; I have nothing 'newer', so I can't try it on an intel based machine.
I use gcc-4.2 (which does _not_ work the same as gcc-4.2 on intel, so it might work fine on intel, even though it fails on PowerPC).

I can compile gcc 4.3.x up to 4.5.x (all inclusive), but 4.6.x is giving me trouble.
Does anyone know how to get me going ?


Love,
Jens

It shouldn't be trying to allocate that much, it looks like an
overflow, or a negative number wrapping to a very large unsigned one.

Since the problem may be in the GCC 4.2 you got from Apple, have you
tried using a different compiler to build 4.6?  I would try using GCC
4.5, which you can build successfully.

I just checked the size of insn-attrtab.c, it's actually 1.4GB! :S

I forgot to mention that this is a cross-compiler I'm building for the ARM target on my Mac.
On my Mac, I have gcc-4.0 and gcc-4.2.
gcc builds fine for ARM, but I do not yet know if it builds for Mac/PowerPC.

2 questions:
1: Wouldn't gcc-4.5 [by default, that is] have the same malloc-problem as 4.2 ?
2: Doesn't Apple compile gcc in a special way, so that it differs from a standard ./configure && make install ?

Anyway, I'm trying (once again) to compile gcc for Mac/PowerPC


Love,

This is the most silly way of 'fixing' such errors, but very straight-forward and simple:

I quit all applications (Safari, GyazMail, etc, whatever I could find - except for some minor apps like TextEdit, Terminal and Activity Monitor)

I wrote a small test command-line utility, which tested how large blocks I could 'malloc'. The result was 2GB blocks (0x7fffffff), larger than that, we'd get a negative number (it's kinda silly to make a length-argument a signed integer in my opinion).

Then I tried building gcc-4.6.3 (for ARM) again, and malloc succeeded this time; I finally got a complete ARM build for the very first time on a PPC Mac!
(I'll have to fine-tune it, before I start using it, though - so I'll have to build a number of times still, but now it seems I'm over the worst part)
Thank you all, for the suggestions and help, especially Johathan for the invaluable help you've provided over a long time!

For the people sifting the Web...
Basics are:
* Use gcc-4.2 for compiling, gcc-4.0 will not succeed.
* don't touch the ABI; leave it as is, the default is working fine.
* don't CC='gcc -m32'. The default is fine. You can, of course CC='gcc -mcpu=... -mtune=...'
* don't compile gmp, mpfr and mpc in advance, make a symlink from within gcc's source directory, make sure the names of the symlinks are 'gmp', 'mpfr', 'mpc' and they point to the root of the unpacked library archives; eg. symlink 'gmp' points to 'gmp-5.0.4'; I made some mistakes with the symlinking a couple of times, so if you're getting any errors regarding gmp, mpfr and mpc, it's most likely because your symlinks are incorrect, check them again.

I placed the build directory outside the source directories; I find it much more fun to 'rm -R Build' to get a complete clean, than 'make clean' or unpack the source directory all over. ;)
I built the boot-gcc, then newlib, then the real gcc (without running configure again)
