Installation

[Trent]

Just so I know (I’m still unable to get it to compile at all) what are the steps that you are using to get it that far Gordon?

What OS are you using as a base and what are you doing to it after (what packages are you installing?)

[Gordon]

binutils seems to make without error, but I still get the error…

is everything required in the svn archive? (guessing here)

Hi Gordon,

I suspect the earlier GNU tools configure failed.
Go into ~/ellcc/gnu and type “./build”. That should build all the GNU tools, including the assemblers.

Disregard last, I was trying to mimic your file structure – have moved it back and am compiling now.

gnu built ok:

Hi Trent:
Here (as far as i can be sure) are the steps i took to get it going – in case its useful to anyone else getting started:

I created a Ubuntu 12-04 LTS Desktop VM from Ubuntu iso on VMWare Fusion.
(Only take a few minutes to get a clean environment).
I had to load the following packages (commands given):
sudo apt-get update
sudo apt-get install byacc flex
sudo apt-get install zlib1g-dev libncurses5-dev
sudo apt-get install libglib2.0-dev
sudo apt-get install dh-autoreconf
(I hope this list is complete but you’ll found out soon enough 🙂
Then I checkout the latest ellcc from the repo.
Note: svn checkout kept failing – repo is a long way away from me and latency is a killer – I kept repeating the failing checkout
– finally worked out i could update the partly populated repository with svn update 🙂
It then build successfully from the ./build script

[Gordon]

When I omit the last option I get the EABI5 failure:
/home/gordon/Applications/ellcc/bin/ecc-ld: error: Source object /home/gordon/Applications/ellcc/bin/../libecc/lib/arm/linux/crtend.o has EABI version 0, but target a.out has EABI version 5

gordon@ubuntu:~/armwork$ /home/gordon/Applications/ellcc/bin/ecc helloarm.c -target arm-ellcc-linux-eabi -march=armv7 -mfpu=vfp -mfloat-abi=softfp

But when i use it I get nothing:
gordon@ubuntu:~/armwork$ /home/gordon/Applications/ellcc/bin/ecc helloarm.c -target arm-ellcc-linux-eabi -march=armv7 -mfpu=vfp -mfloat-abi=softfp -no-integrated-as
gordon@ubuntu:~/armwork$

just the prompt (I’m probably doing something silly)

my bin directory looks like:
gordon@ubuntu:~/Applications/ellcc/bin$ ls

OSX – Mavericks story.

With the latest code, I can almost build it using CLANG on Mavericks, still has the same EABI5/0 issue for arm, and the qemu is not building correctly – has no “qemu-mips” and “qemu-arm” (etc.) components int eh bin directory despite no errors on build. The bin directory listing is:
FileCheck ecc-c++filt ecc-size llvm-dis llvm-symbolizer qemu-system-mips
arm-elf-as ecc-elfedit ecc-strings llvm-dwarfdump llvm-tblgen qemu-system-mipsel
bugpoint ecc-embedspu ecc-strip llvm-extract macho-dump qemu-system-ppc
c-index-test ecc-gdb i386-elf-as llvm-link microblaze-elf-as qemu-system-ppc64
clang-check ecc-gprof llc llvm-mc mips-elf-as qemu-system-sparc
clang-format ecc-ld lli llvm-mcmarkup ncurses5-config qemu-system-x86_64
clang-tblgen ecc-ld.bfd lli-child-target llvm-nm not sparc-elf-as
count ecc-lit llvm-ar llvm-objdump opt x86_64-elf-as
ecc ecc-nm llvm-as llvm-ranlib ppc-elf-as
ecc++ ecc-objcopy llvm-bcanalyzer llvm-readobj ppc64-elf-as
ecc-addr2line ecc-objdump llvm-config llvm-rtdyld qemu-system-arm
ecc-ar ecc-ranlib llvm-cov llvm-size qemu-system-i386
ecc-as ecc-readelf llvm-diff llvm-stress qemu-system-microblaze

So to recap, very close with Ubuntu 12.04 and very close with Mavericks. (Centos looks pretty hard as most of the tools are need updating).

What OS are you using to build – it might be easier to just make a VM of the right flavor to run ellcc.

Trent: any luck?

Hi,

It turns out that because of the way that ELLCC is built, you don’t need to build it specifically for each individual Linux distribution. ELLCC is statically linked after you run the top-level build script twice, so does not depend on userland shared libraries.

I made a tar file containing a binary distribution for x86_64 Linux systems as a test. I then created a CentOS 6.5 virtual machine to try it on.
After I logged on to the virtual machine I did the following:

wget ftp://ellcc.org/pub/x86_64-ellcc-linux.tgz
tar xvfpz x86_64-ellcc-linux.tgz
cat hello.c
#include 

int main(int argc, char **argv)
{
        printf("hello world\n");
}

ellcc/bin/ecc -target x86_64-ellcc-linux hello.c
./a.out
hello world

Then, for the ARM:

ellcc/bin/ecc -target arm-ellcc-linux-eabi -march=armv7 -mfpu=vfp -mfloat-abi=softfp -no-integrated-as hello.c
file a.out
a.out: ELF 32-bit LSB executable, ARM, version 1, statically linked, BuildID[sha1]=bd8055c52cb24e047da4b7be4cd697548fbacd64, not stripped

[Gordon]

Hi Rich, I cant replicate you success, the x86 example works well, but I still get the EABI5 error which stops the compile for arm.

This was in a Centos 6.5 x64 virtual machine with a Mavericks host – is that likely to be a factor (I’m hoping not).

[richKeymaster]

Hi Gordon,

The ARM still needs -no-integrated-as. I haven’t had a chance to fix that yet.

-Rich

[richKeymaster]

Gordon,

I missed your previous post about getting nothing when you used -no-integrated-as. That’s good! Nothing means that the output file was created and is named a.out. Put it on your ARM board and have it say hello.

-Rich

Hi Rich, I’m gett an illegal instruction now – could be some other mismatch.
I tried chaging the endianness, but hen I got a non executable error…

Nore: My embedded ARM Linux DMESG is:
Linux version 2.6.35.3-571-gcca29a0 (dave@dave-debian) (gcc version 4.4.4 (4.4.4_09.06.2010) ) #2 PREEMPT Tue Feb 19 11:17:33 PST 2013
CPU: ARM926EJ-S [41069265] revision 5 (ARMv5TEJ), cr=00053177
CPU: VIVT data cache, VIVT instruction cache
Machine: Freescale MX28EVK board
what march or mcpu option do you recommend?

[Trent]

I’ve gotten it to compile the first time, However the second compile has an error (getting ellcc to build itself)

/home/build/nuchain/bin/ecc -c -target x86_64-ellcc-linux -DHAVE_CONFIG_H -I. -I../../../src/binutils/intl ../../../src/binutils/intl/ngettext.c

Options:
-b file_prefix set filename prefix (default “y.”)
-d write definitions (y.tab.h)
-i write interface (y.tab.i)
-g write a graphical description
-l suppress #line directives
-o output_file (default “y.tab.c”)
-p symbol_prefix set symbol prefix (default “yy”)
-P create a reentrant parser, e.g., “%pure-parser”
-r produce separate code and table files (y.code.c)
-s suppress #define’s for quoted names in %token lines
-t add debugging support
-v write description (y.output)
-V show version information and exit

Also after I get it compiling, If I were to want to install other libraries so that ellcc can access them (for various targets) how would I go about that?
