llvm dev - Dec 2008 - [LLVMdev] Error when attempting to build llvm-gcc-4.2-2.4.source on Mac OS X 10.5.6

Hi,
        I'm new to LLVM and I want to setup the Trident Compiler  
system on Mac OS X. I downloaded the llvm-gcc-4.2-2.4.source.tar.gz  
package, created a build directory and ran the following command to  
configure

$ ../src/configure --program-prefix=llvm- --disable-bootstrap --enable- 
checking --enable-languages=c,c++
$ make -j 2

Configure works fine, but I get the following error after running the  
make command:

gcc -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict- 
prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-

attribute -fno-common  -mdynamic-no-pic -DHAVE_CONFIG_H -I. -I. -

undeclared (first use in this function)
../../src/gcc/tree-nested.c:1846: error: (Each undeclared identifier  
is reported only once

in.)
make[2]: *** [tree-nested.o] Error 1
make[1]: *** [all-gcc] Error 2
make: *** [all] Error 2

How can I resolve this error?

Best regards,

Hello, Elvis

You haven't configured llvm-gcc properly. Please do read readme.llvm file.

However, afair, Trident was LLVM 1.5-based, and it will require
massive rewrite to use LLVM 2.x
(bytecode format was also changed)

Thanks Anton,
                               Yes, I just realized this. I am going  
through the steps now.

So, you're saying that Trident will not work with llvm-2.4?

If I have to use llvm-1.5, which is the corresponding C front end? I  
couldn't locate the C front end package on the Trident Compiler   
website.

Best regards,

Elvis Dowson

Hi,
        Here are the steps that I followed to create a successful  
build on Mac OS X 10.5.6.

Best regards,

Technote llvm-gcc4.2-2.4-001: How to build llvm-gcc4.2-2.4 for Mac OS  
X 10.5.6

Procedure

Step 01: Configure, build and install llvm-2.4.

Directory structure:

llvm-2.4
	/	build
	/	src

The following commands will build a debug version of llvm.

$ cd build
$ ../src/configure
$ make -j 2 ENABLE_OPTIMIZED=0

To build a release version of llvm, type the following command

$ make ENABLE_OPTIMIZED=1

Step 02: Configure, build and install llvm-gcc4.2-2.4.

When building the llvm-gcc front end with a debug version of llvm,  
ensure that the --enable-checking configure option is set.

If building for Darwin/X86 (32-bit support):
     TARGETOPTIONS='--with-arch=nocona --with-tune=generic'

In addition, you *must* specify the following options to configure:
   --with-gxx-include-dir=/usr/include/c++/4.0.0

With these options, llvm-gcc will build the same way as Apple's system  
GCC.

Directory structure:

llvm-gcc4.2-2.4
	/	build
	/	install
	/	src

Type the following commands to build a debug version of llvm-gcc

$ cd build
$ export TARGETOPTIONS='--with-arch=nocona --with-tune=generic'
$ export TRIPLE=i386-apple-darwin9.6.0
$ export BUILDOPTIONS=LLVM_VERSION_INFO=2.4
$ ../src/configure --enable-checking --with-gxx-include-dir=/usr/ 
include/c++/4.0.0 --prefix=`pwd`/../install --program-prefix=llvm- -- 
enable-llvm=$LLVM_HOME/build --enable-languages=c,c++$EXTRALANGS  
$TARGETOPTIONS --disable-bootstrap --disable-multilib
$ make $BUILDOPTIONS -j 2 ENABLE_OPTIMIZED=0
$ make install

Step 03: Update PATH environment variable

export LLVM_HOME=$HOME/Tool/llvm-2.4
export LLVM_GCC_HOME=$HOME/Tool/llvm-gcc4.2-2.4
export PATH=$PATH:$LLVM_HOME/build/Debug/bin:$LLVM_GCC_HOME/install/bin

Step 04: Verify the installation

$ llvm-gcc -v
$ gcc version 4.2.1 (Based on Apple Inc. build 5623) (LLVM build 2.4)

If the -v line above doesn't include "LLVM", you probably mistyped
the
--enable-llvm=xxx line and have a normal gcc, not an llvm-gcc.
