[SOLVED] Configuring lazarus for linux arm

[capslock]

Hi folks,

I trying to configure lazarus for linux arm building the compiler my self like described in http://wiki.lazarus.freepascal.org/Android_Interface .

When I tried to compile the first app an error ocurred:

Error: Assembler arm-linuxas not found, switching to external assembling.

Environment:
Ubuntu 9.10 karmic koala
Lazarus 0.9.30.4 (compiled by myself)
fpc 2.4.0

How can I solve this?
I tried the virtual machine available in the wiki, but doesn't not work too.

Error: Assembler arm-linuxas not found...

What's your arm-linux assembler binary name? And in your fpc.cfg, what's your -XP setting?

Thank you for replying, Leledumbo!

I'm a newbie in lazarus. I hope answer your questions correctly:

1) About the arm-linux assembler binary name:

And there are a symbolic links here:

total 0
lrwxrwxrwx 1 root root 27 2013-01-15 07:12 ar -> /usr/local/bin/arm-linux-ar

root@ubuntu:/home/menthor/lazarus/fpc/binutils#
root@ubuntu:/home/menthor/lazarus/fpc/binutils#
root@ubuntu:/home/menthor/lazarus/fpc/binutils#

2) In /etc/fpc.cfg:

#IFDEF FPC_CROSSCOMPILING
#IFDEF NEEDCROSSBINUTILS
  -XP$fpctarget-
#ENDIF NEEDCROSSBINUTILS
#ENDIF

[Leledumbo]

-XP$fpctarget- ...  arm-linux-as

This should be correct, then something must be wrong on your system because it searched for arm-linuxas instead of arm-linux-as (I assume it's not a copy-paste error). Is /usr/local/bin part of your PATH?

Anyway, I don't think your FPC and Lazarus version adequate for compiling for Android. You should use the one pointed by the article.

[capslock]

You right.

There was an incorrect parameter in Project Options | Compiler Options | Other | Custom Options:

-XParm-linux  instead of -XParm-linux-

Now, I received an other error trying to compile my project:

/usr/local/bin/arm-linux-ld: warning: link.res contains output sections; did you forget -T?
/usr/local/bin/arm-linux-ld: skipping incompatible /usr/lib/crti.o when searching for /usr/lib/crti.o
/usr/local/bin/arm-linux-ld: cannot find /usr/lib/crti.o
teste.lpr(21) Error: Error while linking
teste.lpr(21) Fatal: There were 1 errors compiling module, stopping

Any idea?

I was tried other versions like described in article, but doesn't work too. It's sounds like a nightmare :-(

[Leledumbo]

skipping incompatible /usr/lib/crti.o when searching for /usr/lib/crti.o

It should NEVER link to that library, it belongs to your system, not the android system. You need to give path to NDK libraries. See this important note.

[capslock]

You right again. The problem was solved.

I made an update for most recent versions of lazarus, fpc, binutils and ubuntu and reconfigure all again from scratch. It's all working properly now.

Thanks for you help

Hello, I'm having the same problem, follow the step by step of http://wiki.lazarus.freepascal.org/Setup_Cross_Compile_For_ARM.

I'm trying to build lazarus and I get the error: /home/mint/lazarus/packager/registration/lazaruspackageintf.pas(104) Error: Assembler arm-linuxas not found, switching to external assembling

Could anyone help me?
