fpc subversion trunk installation on raspberry PI

[nomorelogic]

hi all

I'm trying to install the fpc trunk compiler from subversion on my raspberry.
The distro is gentoo and I've used following commands:

Code: [Select]

1) su
2) mkdir /usr/local/fpc
3) cd /usr/local/fpc
4) wget http://sourceforge.net/projects/freepascal/files/Bootstrap/2.6.2/arm-linux-ppcarm.bz2/download
5) mv download ppcarm.bz2
6) bunzip2 ppcarm.bz2
7) svn co http://svn.freepascal.org/svn/fpc/trunk trunk
8) svn export --force trunk trunktmp
9) cd trunktmp
10) make all OPT='-gl -O3p3' -j 8 FPMAKEOPT="-T 8" FPC=/usr/local/fpc/ppcarm >/usr/local/fpc/makeall.log

when "make all" ends, I get an error.
Attached is the stdout while below you can see other messages printed on shell

Code: [Select]

trunktmp # make all OPT='-gl -O3p3' -j 8 FPMAKEOPT="-T 8" FPC=/usr/local/fpc/ppcarm >/usr/local/fpc/makeall.log

make[2]: ./fpmake: Command not found

make[1]: *** [packages_smart] Error 2
make: *** [build-stamp.arm-linux] Error 2

Any idea about the error?

The warnings are normal.  The error is that it can't find the build tool fpmake. which should be built as part of the build process.

[nomorelogic]

well
looking at last lines in log:

make[3]: Leaving directory `/usr/local/fpc/trunktmp/packages/fpmkunit'
/usr/local/fpc/trunktmp/compiler/ppcarm fpmake.pp  -Fu/usr/local/fpc/trunktmp/packages/fpmkunit/units_bs/arm-linux -Fu/usr/local/fpc/trunktmp/rtl/units/arm-linux  -gl -O3p3

make[2]: Leaving directory `/usr/local/fpc/trunktmp/packages'
make[1]: Leaving directory `/usr/local/fpc/trunktmp'

I repeated manually last commands:
once in '/usr/local/fpc/trunktmp/packages' folder I executed

Code: [Select]

/usr/local/fpc/trunktmp/compiler/ppcarm fpmake.pp [...]and I've got a warning:

/usr/bin/ld: warning: link.res contains output sections; did you forget -T?

anyway fpmake was builted:

Code: [Select]

ls fpmake -l

-rwxr-xr-x 1 root root 4140367 Apr 25 15:34 fpmake

after that I executed (just to check existence)

Code: [Select]

./fpmakeand the answer is:

-bash: ./fpmake: No such file or directory

something went wrong in fpmake compilation?

a little step forward

looking at readelf output in my previous post, I noted:
'[Requesting program interpreter: /lib/ld-linux.so.3]'

well, this library is present as: /lib/ld-linux-armhf.so.3
so I created a link with following command:

Code: [Select]

ln -s ld-linux-armhf.so.3 ld-linux.so.3
now the error is different (and less cryptic):

Code: [Select]

# ./fpmake
The installer encountered the following error:
Access violation

then I tried the entire rebuild and the error was exactly as expected

Code: [Select]

./fpmake compile -T 8 --localunitdir=.. --os=linux --cpu=arm -o -Ur -o -Xs -o -O2 -o -n -o -Fu/usr/local/fpc/trunktmp/rtl/units/arm-linux -o -gl -o -O3p3 -o -darm -o -dRELEASE --compiler=/usr/local/fpc/trunktmp/compiler/ppcarm -bu -o -XX -o -CX
The installer encountered the following error:
Access violation
make[2]: *** [smart] Error 1
make[2]: Leaving directory `/usr/local/fpc/trunktmp/packages'
make[1]: *** [packages_smart] Error 2
make[1]: Leaving directory `/usr/local/fpc/trunktmp'
make: *** [build-stamp.arm-linux] Error 2

well, inspecting with strace I found something, but, since in the meantime 2.6.4 (for arm) was posted, I'll repeat all using the latest version (now I'm trying with 2.6.2) .

[Loesje]

Where did you get your fpc-version from? The default arm-versions of the compiler are for armel. As your ld-linux.so has an 'hf' suffix, I doubt that your system is armel-based. (uname -a will give more information)

You could try to install the fpc-packages from Fedora, which are using hf. (http://koji.fedoraproject.org/koji/buildinfo?buildID=455287)

You can download the patches which are used to build fpc-2.6.2 for Fedora here: http://pkgs.fedoraproject.org/cgit/fpc.git/tree/

In one of those patches the path to the default linker is changed. But it's still different then the name of the linker you found on your system ( /lib/ld-linux-armhf.so.3).

You could try to set the name of the dynamic-linker in your fpc.cfg (add the line: -FL/lib/ld-linux-armhf.so.3) Or to your make options:

make all [your stuff here] OPT=-FL/lib/ld-linux-armhf.so.3

uname

Code: [Select]

pastoo trunktmp # uname -a
Linux pastoo 3.10.37+ #669 PREEMPT Tue Apr 15 14:44:32 BST 2014 armv6l BCM2708 GNU/Linux
ok I'm a bit confused
ld-linux.so has hf suffix but armv6l means armel?

[Loesje]

I'm not 100% sure, but hf just means hardware-floatingpoint support. That's in principle possible with armel *and* armb.

During the bootstrap-process, fpmake is the first application which is build by the new compiler and which is also run. (Except from the compiler itself, but that one doesn't use dynamic linking)

For some reason the compiler you've build does not work very well... You have to find out what's wrong with it.

[nomorelogic]

in fact ppcarm 2.7.1 is built
but I have not yet compiled any source: I would do the job without errors.

If someone has a raspberry and want to try install the fpc trunk, I can share my ssd image (gentoo).

[nomorelogic]

a little step forvard, using this command:

Code: [Select]

# make all OPT='-gl -O3p3' -j 8 FPMAKEOPT="-T 8" FPC=/usr/local/lib/fpc/2.6.4/ppcarm OPT=-FL/lib/ld-linux-armhf.so.3
fpmake was built!

but I've got another error related to assembler (see at the end)

Code: [Select]

seems that the "assembler error" is raised after some assembling statemens
attached you can found the full log
can anyone help me?

related to the build of fpmake, in full log I've found this

crtbegin/end are part of general Linux development packages (iirc on debian and derivatives it is in a package "build-essentials" or so)

P.s. do you REALLY have an 8 core ARM that can uses all cores at the same time? (so not 4.4 little.BIG ?)

emh... no 
I just copy/paste from a script found here

I have not actually checked the parameters as I thought they were correct

Try adding that -Fo in OPT also to fpmakeopt.

[nomorelogic]

compilation success!

now I'm doing some test, I'll post the results
