Cross Compile Build Question

Cross Compile Build Question

[James Don]

Hi ...

I posted a question regarding this a little while ago but I didn't really
get anywhere with solutions I was given ...

I am trying to build GCC with the below 3 scripts build-gccBootStrap.sh,
build-glibc.sh, and build-gccWithGlibc.sh ... I keep having problems once I
get to the part where gcc is build gthr-threads.h ...

I can build glibc and bootstrapped compiler with newlib just fine ...

The error I get is:

In file included from gthr-default.h:1,
                 from ../../gcc-2.95.3/gcc/gthr.h:98,
                 from ../../gcc-2.95.3/gcc/libgcc2.c:3034:
../../gcc-2.95.3/gcc/gthr-posix.h:39: parse error before `__gthread_key_t'

or storage class
../../gcc-2.95.3/gcc/gthr-posix.h:40: parse error before `__gthread_once_t'

../../gcc-2.95.3/gcc/gthr-posix.h:59: `pthread_create' undeclared here (not
in a function)
../../gcc-2.95.3/gcc/gthr-posix.h:78: parse error before `*'
../../gcc-2.95.3/gcc/gthr-posix.h:78: parse error before `)'


I have been told it is probably a problem with --headers ... but I am not so
sure ... I think I have set it up properly ... as you can see below ...

Thanks as always,
Jim

[Allen Curtis]

Let me dig up my notes. I spent an hour with someone before we got this to
work. You needed to comment out some stuff.
