Problems in building gcc on linux

Problems in building gcc on linux

[RakeshN]

 
Hi ,

I am building gcc on linux 6.1 .

My configuration command is ----

configure --target=h8300-hms --host=i386-coff-go32 --build=sun4 --prefix=/b/dosbin

My target is hitachi h8/300 processor for MS-DOS.

After configuring successfully i gave the command

make all

make info 

make install. But there are some errors....

My queries are

1] There is a makefile in each and every directory. Should i make them all individually?

2] There are errors reported during make. Please clarify these errors?

In make all--------

make[1]: i386-coff-go32-ar: Command not found
make[1]: *** [libiberty.a] Error 127
make: *** [all-libiberty] Error 2

In make info-------

make[1]: i386-coff-go32-ar: Command not found
make[1]: *** [libiberty.a] Error 127
make: *** [all-libiberty] Error 2

In make install-----

In file included from /root/rakesh/src/gcc/gencheck.c:21:
hconfig.h:1: auto-build.h: No such file or directory
make[1]: *** [gencheck.o] Error 1
make: *** [install-gcc] Error 2

Thanks in advance

IIRC --host=i386-coff-go32 means you are building it on an
i386-coff-go32 machine, which you are not, since you are in fact
building it on a linux machine. You cannot create a compiler to run on
the hitachi without first creating a cross compiler from linux to the
hitachi and with that gcc (often called i386-go32-gcc or something like
that) compile the compiler you want.

I suggest finding the crossgcc FAQ and following the steps detailed
therein.

Good luck,
Jurriaan

What you are doing is called a Canadian cross. Since your compiler is going to
be hosted on a system (MS-DOS) other than the one you are building it on
(Linux), you must build it on your Linux box with a Linux x MS-DOS cross-
compiler. I.e., you must first build that and then use it to build your MS-DOS
x H8/300 compiler. Building a cross-compiler with a cross-compiler is called
Canadian cross. You must also build a Linux x H8/300 cross-compiler before you
build your MS-DOS x H8/300 cross-compiler, because building the latter will
need it to build target libraries. This is all explained very well in Ian Lance
Taylor's "The GNU configure and build system", see:

No, you just run make in the top level build directory and it will
automatically descend into every subdirectory.

You just have to run make in the top level directory (the same place you ran
configure)

As for the errors, it looks like make can't find binutils for your target.
Assuming you've built/installed them, have a poke around in the gcc
makefiles to figure out why it can't find them.
