Hello,

I am having some difficulty getting Lazarus installed on an Udoo SBC (ARM device).

I installed "lubuntu 12.04 LTS armHF based" from here: http://www.udoo.org/downloads/

I installed FPC from here:
ftp://ftp.freepascal.org/pub/fpc/dist/2.6.4/arm-linux/ then
sudo bash
sh install.sh

Then I installed Lazarus as follows:
svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus cd lazarus
make

then the following errors appeared:
...
Linking ../lazbuild
/usr/bin/ld: warning: ../link.res contains output sections; did you forget -T? /usr/lib/fpc/2.6.4/units/arm-linux/rtl/cprt0.o: In function `_haltproc_eabi': (.text+0x88): undefined reference to `_fini'
/usr/lib/fpc/2.6.4/units/arm-linux/rtl/cprt0.o: In function `_haltproc_eabi': (.text+0x90): undefined reference to `_init'
lazbuild.lpr(1742) Error: Error while linking

make[2]: Leaving directory `/home/debian/lazarus/ide' make[1]: *** [lazbuilder] Error 2
make[1]: Leaving directory `/home/debian/lazarus/ide' make: *** [lazbuild] Error 2
$

Any ideas?

Thanks,
Anthony

The FPC you downloaded probably does not support ARM HF. IIRC, none of 2.6.x does, except that there's a version maintained by Debian with patches. You could try installing that or perhaps compile using FPC trunk (manually or using a tool like fpcup [warning: fpcup author speaking ;)] see here
http://wiki.lazarus.freepascal.org/Odroid#Installing_FPC.2FLazarus_using_fpcup for instructions for installation on another ARMHF+*buntu device so that should be quite usable)

I've had the same problem but only when Synapse is used in my Free Pascal program. Here is something from a year ago but I don't think it is related to my current problem:
http://bugs.freepascal.org/view.php?id=24518

I left messages on 20 and 26 May 2014 on the Synapse list but never heard any more from anyone about this.

Interesting, but why does my program compile OK using FPC 2.6.2 but fails using 2.6.4?

I had the problem on 20 May 2014 and just reverted to 2.6.2 to avoid the problem?

Are you using an ARMHF OS?

,,. and are you using FPC from your OS repository or from another source like the OP?

If your circumstances are the same, then I have no idea.

I don't think so. FPC 2.6.2 works OK. It is a Nexus 7 32 GB tablet 2013 version (I think).

Yes, you mentioned 2.6.2 works OK. You probably have a regular ARM OS that supports non-HF operation which lets you run "normal" (non hardfloat) ARM programs.

I'm using only public FPC releases. I should have done more work and reported this FPC 2.6.4 bug a month ago. Sorry for lack of time to do that.

I was not talking about public releases. I was asking whether you got it as (e.g.) a .deb from the package manager from your OS or downloaded it or did as the OP did:

I installed FPC from here: ftp://ftp.freepascal.org/pub/fpc/dist/2.6.4/arm-linux

... however the question is moot as you don't know if the OS you're is running is ARMHF...

Thank you.

I now have an Odroid U3 and am trying the instructions from your link with the following error in fpcup.log:

It seems fpcup cannot see the SVN repository. Is a simple fix?

Thanks,

Yes, it seems it finds the svn command but has problems downloading.

Try again would be my suggestion. You can also try the svn checkout command manually in the relevant directory to see if that works.

The missing svn (from incomplete directory) was due to the disk size being too small, I just had to enlarge as per leaflet that came with odroid U3. I did not try to run the svn command from the command line before I tried "df -h" to see 100% usage on that drive.

Next, locale was screwed up, fcpup --verbose showed this: svn: warning: cannot set LC_CTYPE locale
svn: warning: environment variable LANG is en_CA.UTF-8 svn: warning: please check that your locale name is correct I had to do this:
sudo locale-gen en_US.UTF-8

Next, there were some errors regarding Lazarus build: fpcup: info: Lazarus: buildmodulecustom: make/lazbuild returned error code 2 Details:
fpcup: info: Error running fpcup. Technical details: error executing sequence useride; line: 2, param: USERIDE fpcup: info: Error running fpcup. Technical details: error executing sequence Only; line: 5, param: useride FPCUp failed.
so I did a "fpcup --clean" then tried the standard command (from your link).

Lazarus is installed now.

Thanks,
Anthony

Hello,
I am using Odroid too. I Update it via update.sh which was created by the people from lazarusforum.de

http://www.lazarusforum.de/viewtopic.php?f=3&t=5520&hilit=+update

But there is a problem with runnning the compiled program. Pressing F9 or CTRL + F9 creates the binary, but the IDE then freezes partly, so that compiling again is impossible (F9 does not run the application, only compile).

I can run the created binary's without Lazarus and all is fine. => So the IDE has do be killed via x-kill after each compile. Can you reproduce this ?

Corpsman

Also, I have a larger project that causes the IDE to restart constantly as soon as the project is loaded. I have not tracked that problem down yet. I just went back to a test project with one button and was able to get that working fine. I will have to do more testing to narrow down the offending part of my large project.

I used the instructions from here:
http://wiki.lazarus.freepascal.org/Odroid#Installing_FPC.2FLazarus_using_fpcup and this command to install Lazarus:
./fpcup_linux_armhf --inifile=fpcupodroid.ini --inisection=full --verbose

I had a problem where the IDE complained about:
Lazarus error lclclasses.pp unit Classes not found so I rebuilt Lazarus (Tools->Build Lazarus) and that seemed to help.

I'm still learning.

Anthony

Note: I get the following warnings:
Warning: "crtbegin.o" not found, this will probably cause a linking failure Warning: "crtend.o" not found, this will probably cause a linking failure

According to this posting, the warnings can be ignored: http://lists.lazarus.freepascal.org/pipermail/lazarus/2013-June/081661.html
