while running configure, i've got this error:

It seems you are not on a Debian x86 VM, please check the requirements to spksrc.

it seems readelf is missing in TC_ENV:

if i add readelf to TOOLS in spksrc.tc.mk like:
TOOLS = ld cpp nm cc:gcc as ranlib cxx:g++ ar strip objdump readelf
the file tc_vars.mk in $(WORK_DIR) seems to be ok:

next try:

if i remove --target-tools-prefix=arm-none-linux-gnueabi- from CONFIGURE_ARGS, it seems readelf would be found:

but readelf seems to be from build-host (no path to toolchain binary) and not from toolchain :-(

http://en.wikipedia.org/wiki/Executable_and_Linkable_Format

"Unlike many proprietary executable file formats, ELF is flexible and extensible, and it is not bound to any particular processor or architecture."

Have you installed build-essentials on your Debian ? I think readelf is part of it.

mfr69bs commented Jun 20, 2012

yes, you are right! but this could only a work-around, because the toolchain contains a readelf, which should be used.

maybe the hardest software to cross-compile: perl :-)

i can compile it in my own environment. actually i use perl-5.14.2 with perlcross from berlios. the following script works for me and i want to switch to spksrc as a new environment.

as i wrote before: when --target-tools-prefix=arm-none-linux-gnueabi- is removed from CONFIGURE_ARGS it starts compling (with the readelf from build-host).

but it fails on new erros:

Well I don't know why the configure script doesn't pick the good one but really that's no big deal. Maybe look into the script and hack some stuff or find a way to pass the good variable that will override the detected "readelf" as it seems that READELF doesn't work.

You should convert your scripts to makefile targets within the Makefile of "perl". There are several places where you can put your targets : (PRE|POST)_(CONFIGURE|COMPILE|INSTALL)_TARGET = myTarget
There are more possibilities but those are the common ones.

Does it work with the readelf from your local system? Can you cross compile perl?

Diaoul commented Jun 20, 2012

I don't know what was your previous process but some stuff is overriden in SPKSRC : environment variables. Try to erase some targets and write them by hand without the $(RUN) so that TC_ENV isn't evaluated.

COMPILE_TARGET = myCompile
myCompile:
    make

and so on

yes, i can cross compile perl in my environment. i provide also a ready-build spk on my homepage (search for "perl mfr spk" on google ;-) ). i need a newer perl on synology for an other open source project im working for. these project need some cpan stuff, that missed at original synology perl. I dont want impose optware to the users.

actually my Makefile within spksrc looks like:

PKG_NAME = perl
PKG_VERS = 5.14.2
PKG_EXT = tar.gz
PKG_DIST_NAME = $(PKG_NAME)-$(PKG_VERS).$(PKG_EXT)

As I said, get rid of $(RUN) and create a target that can reproduce the exact same environment as you have (without all the TC_ENV variables defined). I think maybe the original CC (from host) is needed to do some native compilation in the process. Environment variables could maybe set certain values on variables that do not belong here.

Also, do not hesitate to join #synocommunity on Freenode

ok.. thanks for now.. i will give it a try...

last question:
if i do my own target, do i need the including of spksrc.cross-cc.mk or anything else?

@mfr69bs

mfr69bs commented Jun 20, 2012

another last question: :-)
is there an global variable for the toolchain directory (including bin, libs, include, etc...)?

@Diaoul

Diaoul commented Jun 20, 2012

By target I just meant redefine the compile and install targets just as you did with the configure target.
If you do not use $(RUN) you will have to cd in the good dir yourself and set up environment variables.

Override CONFIGURE_TARGET, COMPILE_TARGET and INSTALL_TARGET and put the same stuff as you do within your env.

As for the paths, don't worry about that just now and hardcode them. You'll replace with the dynamic ones later on when you make a successful build :)

no, not yet. i had to switch back to my own environment, because i had to fix a bug in my perl-package for the other open source project i am working on.

so it's ok, to close this issue at this moment.
