cross compiling gcc for mips

cross compiling gcc for mips

[qi tao]

hello:
I am building a toolchain for mips platform. I am using

binutils-2.17
gcc-4.1.1
glibc-2.4
linux-2.6.17.4
linux-headers-2.6.17.4

First I built binutils and now I was setting up the bootstrap compiler.
However when I do "make all-gcc" I get the following errors:
  

  -c ../../gcc-4.1.1/gcc/crtstuff.c -DCRT_BEGIN \
  -o crtbegin.o

 It would raise the probability of someone being able to provide you some 
help if you set your locale to English before reporting error messages.

You can't build the gcc libraries unless you have a C library first. 
And, of course, you can't build a C library unless you have a compiler
first.  This circular dependency makes bootstrapping a bit tricky.  

The basic process here is that you have to do a glibc make
install-headers first which gives you C library headers, and then a
partial gcc build minus the libraries, then a full glibc build, then a
full gcc build.

This is simpler is you just follow instructions written up by someone
else who already knows how to do it.  The one I recommend is the
crosstool scrips written by Dan Kegel.  There is a pointer to them on
the linux-mips.org wiki.

RE: cross compiling gcc for mips

[Mudeem Iqbal]

Hi,

Initially I was configuring gcc by

../gcc-3.4.3/configure --target=mipsel-linux --prefix=${PREFIX}
--without-headers --with-newlib --enable-languages=c

I looked up a bit and found --disable-threads option, so when I configure
gcc using --disbale-threads option I don't get the the initial threads
related errors but i just get

/home/mudeem/ashwaria_rai/tools/mipsel-linux/bin/ld: crti.o: No such file:
No such file or directory
collect2: ld returned 1 exit status
make[2]: *** [libgcc_s.so] Error 1
make[2]: Leaving directory
`/home/mudeem/ashwaria_rai/build-tools/build-boot-gcc/gcc'
make[1]: *** [libgcc.a] Error 2
make[1]: Leaving directory
`/home/mudeem/ashwaria_rai/build-tools/build-boot-gcc/gcc'
make: *** [all-gcc] Error 2

Steve, if I am specifying --without-headers flag, that means not using
headers at all right??? Actaully I am following the instructions from the
O'Reilly's book "building Embedded Linux Systems" It is written that
--without-headers option is broken in gcc 3.2 and subsequent 3.2.1 releases.
Has it been fixed in gcc 3.4.3 ???

Try using 2.4 headers instead.  I haven't had much success using 2.6 
headers to build a mips (cross)toolchain.

cross compiling gcc for mips

[Mudeem Iqbal]

Hi,

I am building a toolchain for mips platform. I am using

binutils-2.15
gcc-3.4.3
glibc-2.3.3
linux-2.6.9	(from linux-mips.org)

First I built binutils and now I was setting up the bootstrap compiler.
However when I do "make all-gcc" I get the following errors.

Try using 2.4 headers instead.  I haven't had much success using 2.6 
headers to build a mips (cross)toolchain.

Re: cross compiling gcc for mips

[Gilad Rom]

Just incase you haven't tried it yet, I'd recommend
crosstool (http://kegel.com/crosstool/) a very nice
set of scripts to automate the toolchain building
process. Also, uClibc has a very nice toolchain
build script at http://www.uclibc.org/toolchains.html
(if you are aiming for an embedded target).
